Configuration of custom links is stored under `FLUENT_DASHBOARD_QUICK_ACCESS_LINKS` settings key and for current example has following structure:
```python
FLUENT_DASHBOARD_QUICK_ACCESS_LINKS = [
{
'title': '[Custom] Waldur - Cloud Service',
'url': 'https://waldur.com',
'external': True, # adds an icon specifying that this link is external,
'description': 'Open-source Cloud Brokerage Platform',
'attrs': {'target': '_blank'} # add an attribute to generated anchor element which will open link in a new tab.
},
]
```
Here is a short description of link parameters:
| **Name** | **Type** | **Required** | **Description** |
| -------- | -------- | ------------ | --------------- |
| description | string | No | Tool tip on the link |
| external | boolean | No | Specifies whether additional icon indicating an external URL has to be added |
|url | URL | Yes | A URL of the link|
| title | string | Yes | A title of the generated link |
| attrs | dict | No | A dictionary of anchor attributes to be added to generated element |
It is also possible to omit optional fields and add links by specifying only a title and a URL to the generated link.
```python
FLUENT_DASHBOARD_QUICK_ACCESS_LINKS = [
['[Custom] Waldur - Cloud Service', 'https://waldur.com'],
['Find us on GitHub', 'https://github.com/opennode/waldur-core'],
]
```
## Custom templates configuration
To overwrite default templates you should use [django-dbtemplates](https://github.com/jazzband/django-dbtemplates). It allows creation of templates through `/admin`.
## Local time zone configuration
Set `TIME_ZONE` setting in `/etc/waldur/override.conf.py` to use local time zone. By default it is set to UTC. See the [list of time zones](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones) for possible options.

This may indicate a bug causing unbounded data growth. Please investigate the affected tables.
Common causes:
Using a non-unique field in get_or_create() lookup
Missing cascade deletes leaving orphaned records
Excessive logging or audit records
Recommended actions:
Check recent code changes affecting these tables
Review the model's get_or_create() and update_or_create() calls
Verify foreign key cascade behavior
Consider adding cleanup tasks for temporary data

## Roles
### Waldur roles and permissions
# Waldur roles and permissions
## Overview
Waldur provides a flexible Role-Based Access Control (RBAC) system, enabling administrators to manage user permissions efficiently. Roles define the actions users can perform within the system, ensuring structured and secure access to resources.
This guide outlines Waldur's roles, their associated permissions, and how they govern access within the platform.
## Managing roles in Waldur
Roles in Waldur are structured to define user access within specific scopes. The key attributes of a role include:
- **Name** – A unique identifier for the role
- **Scope** – The context in which the role is applicable (e.g., Organization, Project, Call, etc.)
- **Description** – A brief explanation of the role's purpose and responsibilities
- **Active** – Indicates whether the role is currently available for assignment
Users can be assigned one or more roles within an Organization, Project, Call, Offering, Service Provider, Proposal, or Call managing organization scope.
## Default roles and permissions
Waldur provides predefined roles to streamline access management across different scopes. Below is an overview of available roles, grouped by scope.
### Organization roles
**Scope**: Organization
| Name | Description | Active |
|------|-------------|--------|
| Customer owner | The highest-level role in an organization, granting full administrative control | Yes |
| Customer manager | A managerial role for service providers within an organization | Yes |
| Customer support | Provides limited support access within an organization | No |
### Project roles
**Scope**: Project
| Name | Description | Active |
|------|-------------|--------|
| Project administrator | Grants full control over a project, including resource and order management | Yes |
| Project manager | Similar to the administrator role but includes additional permission management capabilities | Yes |
| Project member | A limited role with basic project access | No |
### Offering roles
**Scope**: Offering
| Name | Description | Active |
|------|-------------|--------|
| Offering manager | Manages an offering's configuration and associated resources | Yes |
### Call managing organization roles
**Scope**: Call managing organization
| Name | Description | Active |
|------|-------------|--------|
| Customer call organizer | An organization-specific role for handling calls | Yes |
### Call roles
**Scope**: Call
| Name | Description | Active |
|------|-------------|--------|
| Call manager | Oversees calls and proposal approvals | Yes |
| Call reviewer | A role dedicated to reviewing submitted proposals | Yes |
### Proposal roles
**Scope**: Proposal
| Name | Description | Active |
|------|-------------|--------|
| Proposal manager | Responsible for managing proposals within a call | Yes |
### Service provider roles
**Scope**: Service provider
| Name | Description | Active |
|------|-------------|--------|
| Service provider manager | Manages service provider-specific settings and operations | Yes |
## Role assignment and management
Roles are assigned to users based on their responsibilities and required access levels. Administrators can:
- Add or remove user roles
- Modify permissions associated with roles
- Revoke roles manually or set expiration times for temporary access
## Managing roles via the interface
The Waldur administration interface offers an intuitive way to manage user roles. Staff users can:
1. Navigate to the Administration panel
2. Select the User roles section under Settings menu
3. Modify existing roles by updating permissions or changing their status
4. Disable roles as needed
Using the administration interface simplifies role management and ensures a structured approach to access control.
⚠️ **Important notes**:
- Roles should follow the principle of least privilege
- Some roles are disabled by default (e.g., Customer support)
- Regular audits of role assignments are recommended
- Certain roles are scope-restricted (e.g., Customer call organizer)
- Changes to role permissions should be carefully considered
- Document any custom role configurations

## Billing
### Billing and accounting in Waldur
# Billing and accounting in Waldur
Waldur's accounting and billing components are responsible for collecting accounting data and presenting
it to end users. It features built-in reporting and accounting functionality, enabling the tracking of
usage information for each project and its resources. During the service offering creation process,
providers can define accounting components (such as CPU-h, GPU-h, and storage for HPC; CPU, RAM, and
storage for VMs) and set the pricing plans for each component. Consumers can view usage information
according to the policies established by the provider.
From a provider point of view, Waldur supports invoice generation and exposes enough of information via APIs to
integrate with custom payment providers.
Waldur offers convenient tools for consumers to view resource usage information. The user interface displays
overall usage data within a project and breaks down monthly usage across resource components such as CPU,
GPU, and storage. End users can export this usage data in PDF, CSV, and XLSX formats. Access to information
varies by user role: project members can see details for their specific projects, while organization owners
can view information for all projects within their organization.
In addition to that, Waldur offers convenient way for exporting the usage information for visualization [with
Grafana](grafana.md).

## Identity Providers
### LDAP
# LDAP
Waldur allows you to authenticate using identities from a LDAP server.
## Prerequisites
- Below it is assumed that LDAP server is provided by FreeIPA. Although LDAP authentication would work with any other
LDAP server as well, you may need to customize configuration for Waldur MasterMind.
- Please ensure that Waldur Mastermind API server has access to the LDAP server. By default LDAP server listens
on TCP and UDP port 389, or on port 636 for LDAPS (LDAP over SSL). If this port is filtered out by firewall,
you wouldn't be able to authenticate via LDAP.
- You should know LDAP server URI, for example, FreeIPA demo server has ``ldap://ipa.demo1.freeipa.org``.
- You should know username and password of LDAP admin user. For example, FreeIPA demo server uses
username=admin and password=Secret123.
### Add LDAP configuration to Waldur Mastermind configuration
Example configuration is below, please adjust to your specific deployment.
```python
import ldap
from django_auth_ldap.config import LDAPSearch, GroupOfNamesType
# LDAP authentication.
# See also: https://django-auth-ldap.readthedocs.io/en/latest/authentication.html
AUTHENTICATION_BACKENDS += (
'django_auth_ldap.backend.LDAPBackend',
)
AUTH_LDAP_SERVER_URI = 'ldap://ipa.demo1.freeipa.org'
# Following variables are not used by django-auth-ldap,
# they are used as templates for other variables
AUTH_LDAP_BASE = 'cn=accounts,dc=demo1,dc=freeipa,dc=org'
AUTH_LDAP_USER_BASE = 'cn=users,' + AUTH_LDAP_BASE
# Format authenticating user's distinguished name using template
AUTH_LDAP_USER_DN_TEMPLATE = 'uid=%(user)s,' + AUTH_LDAP_USER_BASE
# Credentials for admin user
AUTH_LDAP_BIND_DN = 'uid=admin,' + AUTH_LDAP_USER_BASE
AUTH_LDAP_BIND_PASSWORD = 'Secret123'
# Populate the Django user from the LDAP directory.
AUTH_LDAP_USER_ATTR_MAP = {
'full_name': 'displayName',
'email': 'mail'
}
# Set up the basic group parameters.
AUTH_LDAP_GROUP_BASE = "cn=groups," + AUTH_LDAP_BASE
AUTH_LDAP_GROUP_FILTER = "(objectClass=groupOfNames)"
AUTH_LDAP_GROUP_SEARCH = LDAPSearch(AUTH_LDAP_GROUP_BASE,
ldap.SCOPE_SUBTREE, AUTH_LDAP_GROUP_FILTER)
AUTH_LDAP_GROUP_TYPE = GroupOfNamesType(name_attr="cn")
AUTH_LDAP_USER_FLAGS_BY_GROUP = {
'is_staff': 'cn=admins,' + AUTH_LDAP_GROUP_BASE,
'is_support': 'cn=support,' + AUTH_LDAP_GROUP_BASE,
}
```
Configuration above is based on LDAP server exposed by FreeIPA. To make it work, there are some things
that need to be verified in FreeIPA:
1. Ensure that admins and support groups exist in LDAP server. You may do it using FreeIPA admin UI.
[[Image: FreeIPA groups]](img/freeipa-groups.png)
2. If user is assigned to admins group in LDAP, he becomes staff in Waldur.
If user is assigned to support group in LDAP, he becomes support user in Waldur.
For example, consider the manager user which belong to both groups:
[[Image: Manager user]](img/manager-freeipa.png)
## Field mapping
``displayName`` attribute in LDAP is mapped to full_name attribute in Waldur.
``mail`` field in LDAP is mapped to email attribute in Waldur.
Consider for example, the following user attributes in LDAP:
[[Image: LDAP explorer]](img/manager-ldap-explorer.png)
Here's how it is mapped in Waldur:
[[Image: Waldur admin]](img/manager-django-admin.png)
And here's how it is displayed when user initially logs into Waldur via HomePort:
[[Image: Homeport login]](img/manager-waldur.png)

### MyAccessID
# MyAccessID
Waldur supports integration with [MyAccessID](https://wiki.geant.org/display/MyAccessID/MyAccessID+Home) identity service.
The MyAccessID Identity and Access Management Service is provided by GEANT with the purpose of offering a common
Identity Layer for Infrastructure Service Domains (ISDs).
The AAI proxy of MyAccessID connects Identity Providers from eduGAIN, specific IdPs which are delivered in context of
ISDs such as HPC IdPs, eIDAS eIDs and potentially other IdPs as requested by ISDs.
MyAccessID delivers the Discovery Service used during the user authentication process for users to choose their IdP.
It enables the user to register an account in the Account Registry, to link different identities and it guarantees
the uniqueness and persistence of the user identifier towards connected ISDs.
To enable MyAccessID, please [register a new client](https://wiki.geant.org/display/MyAccessID/Registering+Relying+Parties)
for Waldur deployment and set configuration settings for MyAccessID.
Check [configuration guide](../mastermind-configuration/configuration-guide.md) for available settings.
## Fetch user data using CUID of a user
You can use CUID of user in order to fetch user permissions from MyAccessID registry.
[This document](../waldur-shell.md) describes how to perform it via Waldur shell.
---
### TARA
# TARA
Waldur supports integration with [TARA](https://tara.ria.ee/) authentication service.
To enable it, please register a new client for Waldur deployment and set configuration settings for TARA.
Check [configuration guide](../mastermind-configuration/configuration-guide.md) for available settings.

### eduGAIN
# eduGAIN
## Overview
[eduGAIN](https://wiki.geant.org/display/eduGAIN/eduGAIN+Home) is a global federation of identity and service
providers, based technically on SAML2.
In order to allow eduGAIN users to access Waldur, there are two steps:
- Waldur deployment must be registered as a service provider in eduGAIN federation.
- Waldur must get a list of identities that are trusted for authentication.
!!! tip
SAML is a complicated and fragile technology. GEANT provides an alternative to direct integration of SAML -
[eduTEAMS](eduTEAMS.md), which exposes an OpenID Connect protocol for service providers.
Waldur relies on [djangosaml2](https://djangosaml2.readthedocs.io/) for the heavylifting of SAML processing,
so for fine tuning configuration, contact corresponding project documentation.
## Registering Waldur as Service Provider
### Add SAML configuration to Waldur Mastermind configuration
Example configuration is below, please adjust to your specific deployment. Once applied, service metadata will be
visible at Waldur deployment URL: ``https://waldur.example.com/api-auth/saml2/metadata/``. That data needs to be
propagated to the federation operator for inclusion into the federation.
!!! tip
[Managed ansible](../managing-with-ansible.md) simplifies configuration of the eduGAIN integration and should
be a preferred method for all supported deployments.

## Adding trusted identity providers
In order to configure Waldur to use SAML2 authentication you should specify identity provider metadata.
- If metadata XML is stored locally, it is cached in the local SQL database. Usually metadata XML file is big, so it
is necessary to use local cache in this case. But you should ensure that metadata XML file is refreshed via cron
on a regular basis. A management command ``waldur sync_saml2_providers`` performs refreshing of the data.
- If metadata XML is accessed remotely, it is not cached in SQL database. Therefore you should ensure that metadata
XML is small enough. In this case you should download metadata signing certificate locally and specify its path in
Waldur configuration. The certificate is used to retrieve the metadata securely. Please note that security
certificates are updated regularly, therefore you should update configuration whenever certificate is updated.
By convention, both metadata signing certificate and metadata itself are downloaded to ``/etc/waldur/saml2`` in
Waldur Mastermind instances.
## References
### TAAT configuration
TaaT certificates can be downloaded from: [http://taat.edu.ee/main/dokumendid/sertifikaadid/](http://taat.edu.ee/main/dokumendid/sertifikaadid/).
Metadata URL for test hub is [https://reos.taat.edu.ee/saml2/idp/metadata.php](https://reos.taat.edu.ee/saml2/idp/metadata.php)
and for production hub is [https://sarvik.taat.edu.ee/saml2/idp/metadata.php](https://sarvik.taat.edu.ee/saml2/idp/metadata.php).
Note, the certificate must correspond to the hub you want connect to.
#### Using Janus
[Janus](https://taeva.taat.edu.ee/module.php/janus/index.php) is a self-service for managing Service Provider records.
- Create a new connection:
[[Image: Janus]](img/janus-add-new.png)
New connection ID must be equal to the base_url in saml.conf.py + /apu-auth/saml2/metadata/
- Choose SAML 2.0 SP for connection type.
- Click Create button
- In connection tab select or create ARP. Fields that ARP include must be in the saml_attribute_mapping.
- Navigate to the Import metadata tab and paste same URL as in the first step. Click on the Get metadata.
- Navigate to the Validate tab and check whether all the tests pass. You can fix metadata in Metadata tab.
## HAKA configuration
Production hub metadata is described at [https://wiki.eduuni.fi/display/CSCHAKA/Haka+metadata](https://wiki.eduuni.fi/display/CSCHAKA/Haka+metadata).
Test hub metadata is described at [https://wiki.eduuni.fi/display/CSCHAKA/Verifying+Haka+compatibility](https://wiki.eduuni.fi/display/CSCHAKA/Verifying+Haka+compatibility).
## FEDI configuration
Production hub metadata is described at [https://fedi.litnet.lt/en/metadata](https://fedi.litnet.lt/en/metadata).
Discovery is supported: [https://discovery.litnet.lt/simplesaml/module.php/discopower/disco.php](https://discovery.litnet.lt/simplesaml/module.php/discopower/disco.php).

### eduTEAMS
# eduTEAMS
Waldur supports integration with [eduTEAMS](http://keycloak.org/) identity service.
To enable it, please [register a new client](https://wiki.geant.org/display/eduTEAMS/Registering+services+on+the+eduTEAMS+Service)
for Waldur deployment and set configuration settings for eduTEAMS.
Check [configuration guide](../mastermind-configuration/configuration-guide.md) for available settings.
## Fetch user data using CUID of a user
You can use CUID of user in order to fetch user permissions. [This file](../../integrator-guide/APIs/permissions.md) describes how to perform it, you only need to provide CUID as a username.
---
### FreeIPA
# FreeIPA
!!! tip
For integrating FreeIPA as source of identities, please see [LDAP](LDAP.md).
This module is about synchronising users from Waldur to FreeIPA
For situations when you would like to provide access to services based on the Linux usernames, e.g. for SLURM
deployments, you might want to map users from Waldur (e.g. created through eduGAIN) to an external FreeIPA service.
To do that, you need to enable module and define settings for accessing FreeIPA REST APIs. See
[Waldur configuration guide](../mastermind-configuration/configuration-guide.md) for the list of supported FreeIPA
settings.
At the moment at most one deployment of FreeIPA per Waldur is supported.
---
### Keycloak
# Keycloak
Waldur supports integration with [Keycloak](http://keycloak.org/) identity manager.
Below is a guide to configure Keycloak OpenID Connect client and Waldur intergration.
## Configuring Keycloak
Instructions below are aimed to provide a basic configuration of Keycloak, please refer to Keycloak documentation for full details.
1. Login to admin interface of Keycloak.
2. Create a new realm (or use existing)
[[Image: New realm]](img/keycloak-add-realm.png)
3. Open a menu with a list of clients.
[[Image: List clients]](img/keycloak-client-list.png)
4. Add a new client for Waldur by clicking on `Create client` button.
[[Image: Add client]](img/keycloak-add-client.png)
5. Make sure that `Client authentication` is enabled.
[[Image: Set access type]](img/keycloak-client-access-type.png)
6. Change client's Valid redirect URIs to "*".
[[Image: Valid redirect URIs]](img/keycloak-client-redirect.png)
7. Copy secret code from `Credentials` tab.
[[Image: Secret code]](img/keycloak-client-secret.png)
8. You can find the settings required for configuration of Waldur under the following path on your Keycloak deployment (change `test-waldur` to the realm that you are using): `/realms/test-waldur/.well-known/openid-configuration`
## Configuring Waldur
1. Make sure `SOCIAL_SIGNUP` is added to the list of available authentication methods:
```python
WALDUR_CORE['AUTHENTICATION_METHODS'] = ["LOCAL_SIGNIN", "SOCIAL_SIGNUP"]
```
[[Image: Identity providers]](img/keycloak-identity-providers.png)
3. Open Keycloak identity provider details by clicking on `Edit` menu of Keycloak dropdown menu
[[Image: HomePort provider details]](img/keycloak-homeport.png)
4. Copy `Client ID`, `Client secret` and `Discovery URL`. For extra security, enable SSL, PKCE and post-logout redirect.

## Cloud Providers
### Azure
# Azure
## Overview
This guide will help you set up Azure integration with Waldur by creating a service principal and collecting the necessary credentials. You can use either the **Azure CLI** (recommended) or the **Azure Portal**.
## Prerequisites
- An Azure account with an active subscription
- One of the following:
- **Azure CLI installed** (for CLI method) - [Install Azure CLI](https://learn.microsoft.com/en-us/cli/azure/install-azure-cli)
- **Sufficient Azure permissions** (for either method):
- To create service principals: **Cloud Application Administrator** role or higher in Microsoft Entra ID
- To assign roles: **Owner** or **User Access Administrator** role on the subscription
## Login to Azure CLI
```bash
az login
```
This will open a browser window for authentication. Complete the login process.
## Get Your Subscription ID
```bash
az account show --query id --output tsv
```
Save this value - you'll need it for Waldur configuration.
## Register Resource Providers
To avoid errors when creating Virtual Machines and related resources, register the necessary resource providers:
```bash
# Register Network
az provider register --namespace Microsoft.Network
# Register Compute
az provider register --namespace Microsoft.Compute
# Register Storage
az provider register --namespace Microsoft.Storage
```
**Verify registration:**
```bash
az provider show -n Microsoft.Network --query "registrationState"
# Should output: "Registered"
```
## Create Service Principal with Role Assignment
Run the following command to create a service principal with **Contributor** access to your subscription:
```bash
az ad sp create-for-rbac \
--name "waldur-integration" \
--role Contributor \
--scopes /subscriptions/
```
Replace `` with the subscription ID from Step 2.

You can use a different role if needed. See [Azure built-in roles](https://learn.microsoft.com/en-us/azure/role-based-access-control/built-in-roles) for other options.
## Save the Output
The command will output JSON containing all the credentials you need:
```json
{
"appId": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"displayName": "waldur-integration",
"password": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"tenant": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
}
```
**Map these values for Waldur:**
- `appId` → **Client ID**
- `password` → **Client Secret**
- `tenant` → **Tenant ID**
- Subscription ID from Step 2 → **Subscription ID**
!!! warning
The `password` (Client Secret) is only shown once. Save it immediately in a secure location.

### Custom scripts
# Custom scripts
`Custom scripts` is a type of plugin that allows defining custom scripts that are executed
at different lifecycle events of the resource. The scripts are executed in one time containers.
Depending on the deployment type, it can be either a docker container for docker-compose-based, or
Kubernetes Jobs for Helm-based deployments.
The following lifecycle events are supported:
- Creation;
- Update - change of plans or limits;
- Termination;
- Regular updates - executed once per hour, aka pull script.
## Script output format
It is possible to control certain aspects of resource management with outputs of the custom scripts.
Below we list currently supported conventions and their impact.
### Creation script
You can set the the backend_id of the created resource by passing a single string as the last
line of the output.
```python
# for python-based scripts
import uuid
UUID = uuid.uuid4()
print(UUID)
```
If you want to save additional metadata, then last line of output should consist of 2 space separated strings:
- ID of the created resource that will be saved as backend_id;
- Base64 encoded metadata object.
```python
# for python-based scripts
import base64
import uuid
UUID = uuid.uuid4()
metadata = {"backend_metadata": {"cpu": 1}}
print(UUID + ' ' + base64.b64encode(metadata))
```
### Regular updates script
The script for regular updates allows to update usage information as well as provide updates of reporting.
In all cases the last line should include a base64-encoded string containing a dictionary with keywords:
- "usages" for usage reporting;
- "report" for updating resource report.
Examples of Python-based scripts are:
```python
# for python-based scripts
import base64
info = {
"usages": [
{
"type": "cpu",
"amount": 10
},
]
}
info_json = json.dumps(info)
info_json_encoded = info_json.encode("utf-8")
print(base64.b64encode(info_json_encoded).decode("utf-8"))
```
```python
# for python-based scripts
import base64
info = {
"report": [
{
"header": "header",
"body": "body"
},
]
}
info_json = json.dumps(info)
info_json_encoded = info_json.encode("utf-8")
print(base64.b64encode(info_json_encoded).decode("utf-8"))
```
## Example scripts
Each of the scripts below require access to remote Waldur instance.
Credentials for this passed as environment variables to the scripts with keys:
- `WALDUR_API_URL` - URL of remote Waldur API including `/api/` path, example: `http://localhost/api/`
- `WALDUR_API_TOKEN` - token for a remote user with permissions of service provider owner
### Script for resource creation
In the remote Waldur site, customer and offering should be pre-created for successful resource creation.
Please, add the necessary variables to the local offering's environment:
- `REMOTE_CUSTOMER_NAME` - name of the pre-created customer in the remote Waldur
- `REMOTE_OFFERING_UUID` - UUID of the remote offering for creation of the remote resource
- `PROJECT_NAME` - name of the remote project to be created
- `PI_EMAILS` - optional comma-separated list of emails receiving invitations to the project after creation of the remote resource
- `REMOTE_PROJECT_CREDIT_AMOUNT` - optional amount of credit applied to the remote project

### OpenStack (Tenant)
# OpenStack (Tenant)
## Requirements for OpenStack (Tenant)
OpenStack versions tested:
- Queens
- Rocky
- Stein
- Train
- Ussuri
- Victoria
- Wallaby
- Xena
- Yoga
- Zed
- Antelope
In order to integrate an OpenStack-based cloud as a shared provider, the following data is required:
- URL of Keystone's public endpoint (v3).
- Access to public interfaces of Keystone, Nova, Cinder, Neutron and Glance should be opened to Waldur MasterMind server.
- Admin credentials (username/password) as well as domain name (in case non-default domain is used).
- External network UUID - the network will be by default connected to all created OpenStack Projects (Tenants).
## Advanced settings
It's possible to override some settings for OpenStack in MasterMind admin interface.
To do that, please go to Waldur MasterMind Admin interface with a staff account.
Go to Structure → Shared provider settings and select the one you want to update.
Define specific customisation options. To add an option select append on item block under the object tree. Most typical are:
- external_network_id – external network to connect to when creating a VPC from this provider.
- access_url - a URL to access OpenStack Horizon dashboard from a public network. Typically a reverse proxy URL in production deployments.
- flavor_exclude_regex - flavors matching this regex expression will not be pulled from the backend.
- dns_nameservers - default value for new subnets DNS name servers. Should be defined as list.
- create_ha_routers - create highly available Neutron routers when creating Tenants.
## Support for Organization specific OpenStack networks
You can provide specific external network for all OpenStack Tenants created by Organiztion by providing external
network UUIDs in Organization configuration in Waldur Mastermind admin portal.

### Remote Offering
# Remote Offering
!!! warning
Documentation is in progress. Plugin development is in progress.
## Introduction
It is possible to import into a Waldur offerings from a remote Waldur.
## Pre-requisites
- An organization in the remote Waldur, which will contain requests and projects from the local Waldur.
- Account with owner role that will be used for integration.
- Access to APIs of remote Waldur.
## High level process
- In local Waldur, make sure that you have a [service provider](../../user-guide/service-provider-organization/adding-an-offering.md) organization available.
- Click on "Import offering".
- Input remote Waldur API and authentication token.
- Select the remote organization and offering to be imported.
- Review and activate the offering.
## eduTEAMS account SYNC
In case both local and remote Waldurs are relying on a common set of identities
from [eduTEAMS](../identities/eduTEAMS.md), it is possible to configure synchronisation of the identities as well,
i.e. when a resource is provisioned in a remote Waldur, local accounts from organization and project are pushed and
mapped to the remote project.
!!! note
For this to work, remote Waldur must be integrated with eduTEAMS registry and integration user must have
`identity_manager` role.
## Remote offering actions
Remote offering actions are available in the integration section of the offering edit page.

### Plugin Architecture
# Plugin Architecture
The Waldur Site Agent uses a pluggable backend system that allows
external developers to create custom backend plugins without modifying the core codebase.
## Core architecture & plugin system
```mermaid
---
config:
layout: elk
---
graph TB
subgraph "Core Package"
WA[waldur-site-agent": {
"TOTAL_ACCOUNT_USAGE": {
"": , # Sum of all per-user values
...
},
"": {
"": ,
...
},
"": {
"": ,
...
},
},
"": { ... },
}
```
### Rules
1. **Component keys** must exactly match those in the `backend_components` YAML config.
2. **Values** must be integers in Waldur units (i.e., divide raw backend values
by `unit_factor`).
3. **`TOTAL_ACCOUNT_USAGE`** is a required key and must equal the sum of all
per-user values for each component.
4. If a resource has no usage, return
`{"TOTAL_ACCOUNT_USAGE": {"cpu": 0, "mem": 0, ...}}`.
5. If usage reporting is not supported, return `{}` (empty dict).
### Example: SLURM CPU and memory
Given config:
```yaml
backend_components:
cpu:
unit_factor: 60000
measured_unit: "k-Hours"
mem:
unit_factor: 61440
measured_unit: "gb-Hours"
```
If SLURM reports 120000 cpu-minutes and 122880 MB-minutes for user1:
```python
{
"hpc_my_allocation": {
"TOTAL_ACCOUNT_USAGE": {"cpu": 2, "mem": 2},
"user1": {"cpu": 2, "mem": 2},
}
}
```
Calculation: `120000 / 60000 = 2`, `122880 / 61440 = 2`.
## `supports_decreasing_usage` class attribute
Set this to `True` on your backend class if usage values can decrease between
reports (e.g., a storage backend reporting current disk usage rather than
accumulated compute time).
```python
class MyStorageBackend(BaseBackend):
supports_decreasing_usage = True
```
When `False` (default), the reporting processor skips updates where the new
usage value is lower than the previously reported value, treating it as a
data anomaly.
## `handled_resource_states` class attribute
Controls which resource states the membership processor fetches and processes.
Defaults to `[ResourceState.OK, ResourceState.ERRED]`. Override this when your
backend needs to manage users on resources that are still being provisioned.
```python
from waldur_api_client.models.resource_state import ResourceState
class MyAsyncBackend(BaseBackend):
handled_resource_states = [ResourceState.OK, ResourceState.ERRED, ResourceState.CREATING]
```
## Decision matrix for no-op implementations
If your backend does not support a certain operation, use these return values:
| Method | No-op return | Meaning |
|---|---|---|
| `ping` | `False` | Backend has no health check |
| `diagnostics` | `True` | Diagnostics not implemented but OK |
| `list_components` | `[]` | No component discovery |
| `_get_usage_report` | `{}` | No usage reporting |
| `_collect_resource_limits` | `({}, {})` | No limits support |
| `_pre_create_resource` | `pass` | No pre-creation setup |
| `downscale_resource` | `True` | No downscaling concept |
| `pause_resource` | `True` | No pausing concept |
| `restore_resource` | `True` | No restore concept |
| `get_resource_metadata` | `{}` | No metadata |

storage:
limit: 1000
measured_unit: "GB"
unit_factor: 1

label: "Storage"
```
### `unit_factor` explained
The `unit_factor` converts between Waldur display units and backend-native units:
- `backend_value = waldur_value * unit_factor`
- `waldur_value = backend_value / unit_factor`
Examples:
- CPU k-Hours to SLURM cpu-minutes: `unit_factor = 60000` (60 min x 1000)
- GB-Hours to SLURM MB-minutes: `unit_factor = 61440` (60 min x 1024 MB)
- GB to GB (no conversion): `unit_factor = 1`
## Entry point registration
Register your plugin in `pyproject.toml`:
```toml
[project]
name = "waldur-site-agent-mycustom"
version = "0.1.0"
dependencies = ["waldur-site-agent>=0.7.0"]
[project.entry-points."waldur_site_agent.backends"]
mycustom = "waldur_site_agent_mycustom.backend:MyCustomBackend"
# Optional: component schema validation
[project.entry-points."waldur_site_agent.component_schemas"]
mycustom = "waldur_site_agent_mycustom.schemas:MyCustomComponentSchema"
# Optional: backend settings schema validation
[project.entry-points."waldur_site_agent.backend_settings_schemas"]
mycustom = "waldur_site_agent_mycustom.schemas:MyCustomBackendSettingsSchema"
```
The entry point name (e.g., `mycustom`) is what users put in
`backend_type` or `order_processing_backend` in the config YAML.
## Processor-plugin data flow
Plugins generally do not have direct access to the Waldur API client.
The core processor pre-resolves any Waldur data the plugin might need and
passes it via `user_context`. Plugins return metadata to Waldur by setting
`resource.backend_metadata`.
> **Exception:** `evaluate_pending_order` receives `waldur_rest_client`
> directly, because the order has not been approved yet and no resource
> context exists at that point.
### Pre-resolved data in `user_context`
The processor enriches the `user_context` dict before calling backend
methods. Plugins read from it without making API calls:
| Key | Type | Contents |
|---|---|---|
| `team` | `list[dict]` | Team members with usernames |
| `offering_users` | `list[dict]` | Offering users |
| `ssh_keys` | `dict[str, str]` | Mapping of SSH key UUID → public key text |
| `plan_quotas` | `dict[str, int]` | Plan component quotas (component key → value) |
### Returning metadata via `backend_metadata`
To push metadata back to Waldur (e.g., access credentials, connection
endpoints), set `resource.backend_metadata` in `post_create_resource`:
```python
def post_create_resource(self, resource, waldur_resource, user_context=None):
# ... create credentials, gather endpoints ...
resource.backend_metadata = {
"username": "admin",
"password": generated_password,
"endpoint": "https://service.example.com",
}
# The processor pushes this to Waldur automatically
```
### Data flow

sequenceDiagram
participant P as Processor
participant B as YourBackend

P->>B: post_create_resource(resource, waldur_resource, user_context)
B->>B: Set resource.backend_metadata
B-->>P: Return
P->>W: Push backend_metadata to Waldur
```
### Example: resolving an SSH key UUID from `user_context`
When a resource attribute contains a UUID reference (e.g., an SSH key UUID
from the order form), look it up in the pre-resolved `ssh_keys` dict:
```python
from uuid import UUID
class MyBackend(BaseBackend):
@staticmethod
def _resolve_ssh_key(key_value: str, ssh_keys: dict[str, str]) -> str:
"""Resolve SSH key from pre-resolved context.
If key_value is a UUID, look it up. Otherwise treat as raw key text.
"""
try:
key_uuid = UUID(key_value.strip())
except ValueError:
return key_value # Raw public key text, use as-is
return ssh_keys.get(str(key_uuid), "") or ssh_keys.get(key_uuid.hex, "")
def _pre_create_resource(self, waldur_resource, user_context=None):
user_context = user_context or {}
ssh_keys = user_context.get("ssh_keys", {})
raw_key = waldur_resource.attributes.get("ssh_public_key", "")
resolved_key = self._resolve_ssh_key(raw_key, ssh_keys)
# Use resolved_key for resource setup ...
```
### Design principles
- **Plugins should avoid importing `waldur_api_client`** for runtime API calls.
All Waldur data should come via `user_context` or `BaseBackend` attributes.
The exception is `evaluate_pending_order`, which receives `waldur_rest_client`
for querying project or order data before approval.
- **`service_provider_uuid`** is still set on `BaseBackend` by the processor
and can be read by plugins for constructing backend-side identifiers.
- **Handle missing context gracefully** — `user_context` may be `None` or
missing keys in unit tests. Always default to `{}` or empty values.
## Common pitfalls
### 1. Unit factor direction
The `unit_factor` converts **from Waldur units to backend units** by multiplication.
When reporting usage back, you must **divide** by `unit_factor`. Getting this
backwards causes limits to be set at 1/60000th of the intended value
or usage to be reported 60000x too high.
### 2. Missing TOTAL_ACCOUNT_USAGE
The `_get_usage_report` return dict **must** include a `"TOTAL_ACCOUNT_USAGE"` key
for each resource. If missing, the core will substitute zeros, and reported
usage will appear as zero in Waldur.
### 3. Entry point not discovered
Common causes:
- Package not installed (`uv sync --all-packages`)
- Entry point group name misspelled (must be `"waldur_site_agent.backends"`)
- Entry point value points to wrong class or module
Debug with:
```python
from importlib.metadata import entry_points
print(list(entry_points(group="waldur_site_agent.backends")))
```
### 4. Forgetting super().__init__()
Your backend `__init__` **must** call `super().__init__(backend_settings, backend_components)`.
This sets up `self.backend_settings`, `self.backend_components`, and
`self.client`. Then assign your own client:
```python
def __init__(self, backend_settings, backend_components):
super().__init__(backend_settings, backend_components)
self.backend_type = "mycustom"
self.client = MyCustomClient()
```
### 5. Returning wrong types from client methods
- `get_resource` must return `None` (not raise) when resource is absent.
- `get_association` must return `None` (not raise) when no association exists.
- `list_resources` must return `list[ClientResource]`, not raw dicts.
### 6. Component key mismatch
Component keys in `_get_usage_report` must exactly match the keys in
`backend_components` config. If config has `"cpu"` but you report `"CPU"`,
the usage will be silently ignored.
## Testing guidance
### What to test per mode
| Mode | Test focus |
|---|---|
| `order_process` | `create_resource`, `delete_resource`, limit conversion |
| `report` | `_get_usage_report` format, unit conversion math |
| `membership_sync` | `add_user`, `remove_user`, pause/restore |
| All | `ping`, error handling, edge cases |
### Mock patterns
Mock the client to avoid needing a real backend:
```python
from unittest.mock import MagicMock, patch
from waldur_site_agent.backend.structures import ClientResource, Association
def test_create_resource():
backend = MyCustomBackend(
backend_settings={"default_account": "root", "allocation_prefix": "test_"},
backend_components={"cpu": {"unit_factor": 60000, "limit": 10}},
)
backend.client = MagicMock()
backend.client.get_resource.return_value = None # Resource doesn't exist yet
backend.client.create_resource.return_value = "created"
# ... test resource creation
```
### Fixtures
```python
import pytest
@pytest.fixture
def backend_settings():
return {
"default_account": "root",
"customer_prefix": "c_",
"project_prefix": "p_",
"allocation_prefix": "a_",
}
@pytest.fixture
def backend_components():
return {
"cpu": {
"limit": 10,
"measured_unit": "k-Hours",
"unit_factor": 60000,
"accounting_type": "usage",
"label": "CPU",
},
}
@pytest.fixture
def backend(backend_settings, backend_components):
b = MyCustomBackend(backend_settings, backend_components)
b.client = MagicMock()
return b
```
### Key assertions
```python
# Usage report format
report = backend._get_usage_report(["alloc_1"])
assert "TOTAL_ACCOUNT_USAGE" in report["alloc_1"]
assert all(k in report["alloc_1"]["TOTAL_ACCOUNT_USAGE"]
for k in backend.backend_components)
# Limit conversion
backend_limits, waldur_limits = backend._collect_resource_limits(mock_resource)
assert backend_limits["cpu"] == waldur_limits["cpu"] * 60000
```
## LLM implementation checklist
When implementing a new backend plugin with an LLM, follow these steps in order:
1. **Read existing plugins**: Study `plugins/slurm/` and `plugins/mup/` for patterns.
2. **Copy the template**: Start from `docs/plugin-template/` and rename.
3. **Implement `__init__`**: Call `super().__init__()`, set `backend_type`, create client.
4. **Implement `BaseClient` methods**: Start with `get_resource`, `create_resource`,
`delete_resource`, `list_resources`.
5. **Implement `BaseBackend` abstract methods**: Start with `ping`, then
`_pre_create_resource`, then `_collect_resource_limits`, then `_get_usage_report`.
6. **Handle unit conversion**: Verify `unit_factor` math in both directions.
7. **Write tests**: Mock the client, test each abstract method.
8. **Register entry points**: Add to `pyproject.toml`.
9. **Test integration**: Install with `uv sync --all-packages` and run
`waldur_site_diagnostics`.
10. **Verify**: Run `uv run pytest` and `pre-commit run --all-files`.
### Files to study
- `waldur_site_agent/backend/backends.py` - Base classes with all abstract methods
- `waldur_site_agent/backend/clients.py` - Base client class
- `waldur_site_agent/backend/structures.py` - Data structures (`ClientResource`,
`Association`, `BackendResourceInfo` with `pending_order_id` for async orders
and `backend_metadata` for returning data to Waldur)
- `plugins/slurm/waldur_site_agent_slurm/backend.py` - Reference implementation
(CLI-based)
- `plugins/mup/waldur_site_agent_mup/backend.py` - Reference implementation
(API-based)
### Common mistakes to avoid
- Do not forget `super().__init__(backend_settings, backend_components)`.
- Do not return raw dicts from `list_resources`; return `ClientResource` objects.
- Do not raise exceptions from `get_resource` when resource is absent; return `None`.
- Do not forget the `"TOTAL_ACCOUNT_USAGE"` key in usage reports.
- Do not confuse Waldur units with backend units in `_collect_resource_limits`.
- Do not hardcode component keys; read them from `self.backend_components`.

### Releasing
# Releasing
This document describes how to create a new release of
waldur-site-agent.
## Quick Start
```bash
# Stable release
./scripts/release.sh 0.10.0
# Review the commit, then push:
git push origin main --tags
# Release candidate
./scripts/release.sh 0.10.0-rc.1
git push origin main --tags
```
The script handles version bumping, changelog generation,
committing, and tagging. CI takes care of publishing.
## Prerequisites
- You are on the `main` branch with a clean working tree.
- The [Claude CLI][claude-cli] is installed (used for
changelog generation).
- Python 3.9+ is available.
[claude-cli]: https://docs.anthropic.com/en/docs/claude-code
## What the Release Script Does
`scripts/release.sh ` runs four steps:
### 1. Bump Versions
Calls `scripts/bump_versions.py `, which auto-discovers
all packages and updates:
- `version = "..."` in the root `pyproject.toml`
- `version = "..."` in every `plugins/*/pyproject.toml`
- Internal dependency pins like `waldur-site-agent>=X.Y.Z`
and `waldur-site-agent-keycloak-client>=X.Y.Z`
Plugin discovery is automatic — no hardcoded list. Adding a new
plugin directory with a `pyproject.toml` is all that's needed.
### 2. Generate Changelog
Calls `scripts/changelog.sh `, which:
1. Determines the previous version from `CHANGELOG.md`
(or the latest git tag as fallback).
2. Runs `scripts/generate_changelog_data.py` to collect commits
between the two versions and output structured JSON with
categories, stats, and changed files.
3. Feeds the JSON to Claude with a prompt template
(`scripts/prompts/changelog-prompt.md`) to draft a
human-readable changelog entry.
4. Shows the result and asks you to **accept**, **edit**,
**regenerate**, or **quit**.
5. Prepends the accepted entry to `CHANGELOG.md`.
### 3. Commit
Creates a single commit with the message `Release X.Y.Z`
containing:
- All updated `pyproject.toml` files
- The updated `CHANGELOG.md`
### 4. Tag
Creates a git tag `X.Y.Z` pointing at the release commit.
## What Happens After You Push
Pushing the tag to origin triggers GitLab CI, which:
| Job | What it does |
|---|---|
| **Publish python module** | Bumps versions, builds, publishes to PyPI |
| **Publish Helm chart** | Packages chart, pushes to GitHub Pages |
| **Publish Docker image** | Builds and pushes multiarch images |
| **Generate SBOM** | Creates CycloneDX SBOM, uploads to docs |
## Running Individual Scripts
### Bump versions only
Update all `pyproject.toml` files without committing or tagging:
```bash
python3 scripts/bump_versions.py
```
### Generate changelog only
Generate a changelog entry without bumping versions:
```bash
scripts/changelog.sh
```
This is useful if you want to manually edit the changelog before
running the full release.
### Collect commit data only
Get the raw commit data as JSON (useful for debugging or custom
tooling):
```bash
python3 scripts/generate_changelog_data.py
```
## Version Scheme
All packages (core + plugins) share the same version number,
following `MAJOR.MINOR.PATCH` (e.g. `0.10.0`). Tags do **not**
use a `v` prefix.
Release candidates use the `-rc.N` suffix in git tags
(e.g. `0.10.0-rc.1`). The release script automatically converts
this to PEP 440 format (`0.10.0rc1`) for `pyproject.toml` files
and PyPI publishing. Helm and Docker use the git tag as-is.
## Release Candidates
RC releases follow the same workflow as stable releases:
```bash
./scripts/release.sh 0.10.0-rc.1
git push origin main --tags
```
### How RCs differ from stable releases
| Aspect | Stable | RC |
|---|---|---|
| Git tag | `0.10.0` | `0.10.0-rc.1` |
| pyproject.toml version | `0.10.0` | `0.10.0rc1` (PEP 440) |
| Helm chart version | `0.10.0` | `0.10.0-rc.1` |
| Docker `:latest` tag | Updated | **Not** updated |
| Changelog | New entry | Replaces prior RC entries for same base version |
### Typical RC workflow
1. `./scripts/release.sh 0.10.0-rc.1` — first candidate
2. Test, find issues, fix on main
3. `./scripts/release.sh 0.10.0-rc.2` — replaces rc.1 changelog entry
4. `./scripts/release.sh 0.10.0` — stable release, includes all changes since last stable
## Troubleshooting
### "Error: working tree is not clean"
Commit or stash any uncommitted changes before releasing.
### "Error: tag 'X.Y.Z' already exists"
The version has already been tagged. Choose a different version
number, or delete the tag if it was created by mistake
(`git tag -d X.Y.Z`).
### "Error: 'claude' CLI is not on PATH"
The changelog generation step requires the Claude CLI. Install it
or generate the changelog manually by editing `CHANGELOG.md`
directly, then run the version bump and commit/tag steps
separately:
```bash
python3 scripts/bump_versions.py
# Edit CHANGELOG.md manually
git add pyproject.toml plugins/*/pyproject.toml CHANGELOG.md
git commit -m "Release "
git tag
```
### CI publish job fails
The CI publish job calls `bump_versions.py` as a safety net
before building. If versions are already correct from the release
script, this is a no-op. If someone tagged manually without
running the release script, CI still stamps the correct versions.

### Local pipeline for developers: OpenAPI -> Python SDK -> Site Agent
# Local pipeline for developers: OpenAPI -> Python SDK -> Site Agent
This document describes the process of regenerating and linking the
Waldur Python SDK (`waldur-api-client`) for local development. The SDK
is published to GitHub and consumed as a git dependency, but a local
pipeline is essential when you need to work with unreleased Mastermind
API changes before they are officially deployed.
## Background
The production pipeline runs in GitLab CI on the `waldur-mastermind`
repository:
1. `uv run waldur spectacular` exports the OpenAPI schema.
2. A custom fork of `openapi-python-client` generates the Python SDK.
3. The generated `waldur_api_client/` package is pushed to
`github.com/waldur/py-client` (main branch).
4. `waldur-site-agent` consumes it via `pyproject.toml`:
```toml
[tool.uv.sources]
waldur-api-client = { git = "https://github.com/waldur/py-client.git", rev = "main" }
```
## Prerequisites
Before proceeding, ensure you have the following:
- **uv**: For managing Python dependencies.
- **pip**: For installing the OpenAPI code generator.
- **Waldur MasterMind**: Cloned and set up in a directory (default:
`../waldur-mastermind`).
- **py-client**: Cloned from `github.com/waldur/py-client` (default:
`../py-client`).
## Steps to regenerate and link the SDK
### 1. Generate the OpenAPI schema
In the `waldur-mastermind` directory, run:
```bash
uv run waldur spectacular --file waldur-openapi-schema.yaml --fail-on-warn
```
This produces `waldur-openapi-schema.yaml` with the full API definition.
### 2. Generate the Python SDK from the schema
Still in the `waldur-mastermind` directory:
```bash
pip install git+https://github.com/waldur/openapi-python-client.git
openapi-python-client generate \
--path waldur-openapi-schema.yaml \
--output-path py-client \
--overwrite \
--meta poetry
```
This creates (or overwrites) the `py-client/` directory with the
generated `waldur_api_client` package.
### 3. Copy the generated code to the local py-client checkout
```bash
cp -rf py-client/waldur_api_client ../py-client/waldur_api_client
```
### 4. Point waldur-site-agent at the local py-client
Temporarily override the source in `pyproject.toml`:
```toml
[tool.uv.sources]
waldur-api-client = { path = "../py-client", editable = true }
```
Then re-sync dependencies:
```bash
uv sync --all-packages
```
### 5. Verify
```bash
uv run python -c "import waldur_api_client; print(waldur_api_client.__file__)"
```
This should print the path to your local `py-client` checkout.
## Helper script
A convenience script is provided at `docs/update-local-sdk.sh`:
```bash
./docs/update-local-sdk.sh [mastermind_path] [py_client_path]
```
It automates steps 1-4 above. After running it, remember to revert the
`pyproject.toml` source change before committing.
## Reverting to the published SDK
To switch back to the GitHub-hosted SDK:
```toml
[tool.uv.sources]
waldur-api-client = { git = "https://github.com/waldur/py-client.git", rev = "main" }
```
Then:
```bash
uv sync --all-packages
```

### SLURM Usage Reporting Setup Guide
# SLURM Usage Reporting Setup Guide
This guide explains how to set up a single Waldur Site Agent instance for usage reporting with SLURM backend.
This configuration is ideal when you only need to collect and report usage data from your SLURM cluster to
Waldur Mastermind.
## Overview
The usage reporting agent (`report` mode) collects CPU, memory, and other resource usage data from SLURM
accounting records and sends it to Waldur Mastermind. It runs in a continuous loop, fetching usage data for
the current billing period and reporting it at regular intervals.
## Prerequisites
### System Requirements
- Linux system with access to SLURM cluster head node
- Python 3.11 or higher
- `uv` package manager installed
- Root access (required for SLURM commands)
- Network access to Waldur Mastermind API
### SLURM Requirements
- SLURM accounting enabled (`sacct` and `sacctmgr` commands available)
- Access to SLURM accounting database
- Required SLURM commands:
- `sacct` - for usage reporting
- `sacctmgr` - for account management
- `sinfo` - for cluster diagnostics
## Installation
### 1. Clone and Install the Application
```bash
# Clone the repository
git clone https://github.com/waldur/waldur-site-agent.git
cd waldur-site-agent
# Install dependencies with SLURM plugin
uv sync --package waldur-site-agent-slurm
```
### 2. Create Configuration Directory
```bash
sudo mkdir -p /etc/waldur
```
## Configuration
### 1. Create Configuration File
Create `/etc/waldur/waldur-site-agent-config.yaml` with the following configuration:
```yaml
sentry_dsn: "" # Optional: Sentry DSN for error tracking
timezone: "UTC" # Timezone for billing period calculations
offerings:
- name: "SLURM Usage Reporting"
waldur_api_url: "https://your-waldur-instance.com/api/"
waldur_api_token: "your-api-token-here"
waldur_offering_uuid: "your-offering-uuid-here"
# Backend configuration for usage reporting only
username_management_backend: "base" # Not used in report mode
order_processing_backend: "slurm" # Not used in report mode
membership_sync_backend: "slurm" # Not used in report mode
reporting_backend: "slurm" # This is what matters for reporting
# Event processing (not needed for usage reporting)
stomp_enabled: false
backend_type: "slurm"
backend_settings:
default_account: "root" # Root account in SLURM
customer_prefix: "hpc_" # Prefix for customer accounts
project_prefix: "hpc_" # Prefix for project accounts
allocation_prefix: "hpc_" # Prefix for allocation accounts
# QoS settings (not used in report mode but required)
qos_downscaled: "limited"
qos_paused: "paused"
qos_default: "normal"
# Home directory settings (not used in report mode)
enable_user_homedir_account_creation: false
homedir_umask: "0700"
# Define components for usage reporting
backend_components:
cpu:
limit: 10 # Not used in usage reporting
measured_unit: "k-Hours" # Waldur unit for CPU usage
unit_factor: 60000 # Convert CPU-minutes to k-Hours (60 * 1000)
accounting_type: "usage" # Report actual usage
label: "CPU"
mem:
limit: 10 # Not used in usage reporting
measured_unit: "gb-Hours" # Waldur unit for memory usage
unit_factor: 61440 # Convert MB-minutes to gb-Hours (60 * 1024)
accounting_type: "usage" # Report actual usage
label: "RAM"
```
### 2. Configuration Parameters Explained
#### Waldur Connection
- `waldur_api_url`: URL to your Waldur Mastermind API endpoint
- `waldur_api_token`: API token for authentication (create in Waldur admin)
- `waldur_offering_uuid`: UUID of the SLURM offering in Waldur
#### Backend Settings
- `default_account`: Root account in SLURM cluster
- Prefixes: Used to identify accounts created by the agent (for filtering)
#### Backend Components
- `cpu`: CPU usage tracking in CPU-minutes (SLURM native unit)
- `mem`: Memory usage tracking in MB-minutes (SLURM native unit)
- `unit_factor`: Conversion factor from SLURM units to Waldur units
- `accounting_type: "usage"`: Report actual usage (not limits)
## Deployment
### Option 1: Systemd Service (Recommended)
1. **Copy service file:**
```bash
sudo cp systemd-conf/agent-report/agent.service /etc/systemd/system/waldur-site-agent-report.service
```
1. **Reload systemd and enable service:**
```bash
sudo systemctl daemon-reload
sudo systemctl enable waldur-site-agent-report.service
sudo systemctl start waldur-site-agent-report.service
```
1. **Check service status:**
```bash
sudo systemctl status waldur-site-agent-report.service
```
### Option 2: Manual Execution
For testing or one-time runs:
```bash
# Run directly
uv run waldur_site_agent -m report -c /etc/waldur/waldur-site-agent-config.yaml
# Or with installed package
waldur_site_agent -m report -c /etc/waldur/waldur-site-agent-config.yaml
```
## Operation
### How It Works
1. **Initialization**: Agent loads configuration and connects to SLURM cluster
2. **Account Discovery**: Identifies accounts matching configured prefixes
3. **Usage Collection**:
- Runs `sacct` to collect usage data for current billing period
- Aggregates CPU and memory usage per account and user
- Converts SLURM units to Waldur units using configured factors
4. **Reporting**: Sends usage data to Waldur Mastermind API
5. **Sleep**: Waits for configured interval (default: 30 minutes)
6. **Repeat**: Returns to step 3
### Timing Configuration
Control reporting frequency with environment variable:
```bash
# Report every 15 minutes instead of default 30
export WALDUR_SITE_AGENT_REPORT_PERIOD_MINUTES=15
```
### Logging
#### Systemd Service Logs
```bash
# View service logs
sudo journalctl -u waldur-site-agent-report.service -f
# View logs for specific time period
sudo journalctl -u waldur-site-agent-report.service --since "1 hour ago"
```
#### Manual Execution Logs
Logs are written to stdout/stderr when running manually.
## Monitoring and Troubleshooting
### Health Checks
1. **Test SLURM connectivity:**
```bash
uv run waldur_site_diagnostics
```
1. **Verify configuration:**
```bash
# Check if configuration is valid
uv run waldur_site_agent -m report -c /etc/waldur/waldur-site-agent-config.yaml --dry-run
```
### Common Issues
#### SLURM Commands Not Found
- Ensure SLURM tools are in PATH
- Verify `sacct` and `sacctmgr` are executable
- Check SLURM accounting is enabled
#### Authentication Errors
- Verify Waldur API token is valid
- Check network connectivity to Waldur Mastermind
- Ensure offering UUID exists in Waldur
#### No Usage Data
- Verify accounts exist in SLURM with configured prefixes
- Check SLURM accounting database has recent data
- Ensure users have submitted jobs in the current billing period
#### Permission Errors
- Agent typically needs root access for SLURM commands
- Verify service runs as root user
- Check file permissions on configuration file
### Debugging
Enable debug logging by setting environment variable:
```bash
export WALDUR_SITE_AGENT_LOG_LEVEL=DEBUG
```
## Data Flow
```text
SLURM Cluster → sacct command → Usage aggregation → Unit conversion → Waldur API
↓ ↓ ↓ ↓ ↓
- Job records - CPU-minutes - Per-account - k-Hours - POST usage
- Resource - MB-minutes - Per-user - gb-Hours data
usage - Account data - Totals - Converted
values
```
## Security Considerations
1. **API Token Security**: Store Waldur API token securely, restrict file permissions
2. **Root Access**: Agent needs root for SLURM commands - run in controlled environment
3. **Network**: Ensure secure connection to Waldur Mastermind (HTTPS)
4. **Logging**: Avoid logging sensitive data, configure log rotation
## Historical Usage Loading
In addition to regular usage reporting, the SLURM plugin supports loading historical usage data into Waldur.
This is useful for:
- Migrating existing SLURM usage data when first deploying Waldur
- Backfilling missing usage data due to outages or configuration issues
- Reconciling billing periods with historical SLURM accounting records
### Prerequisites for Historical Loading
**Staff User Requirements:**
- Historical usage loading requires a **staff user API token**
- Regular offering API tokens cannot submit historical data
- The staff user must have appropriate permissions in Waldur
**Data Requirements:**
- SLURM accounting database must contain historical data for the requested periods
- Resources must already exist in Waldur (historical loading cannot create resources)
- Offering users must be configured in Waldur for user-level usage attribution
### Historical Usage Command
```bash
# Load usage for specific date range
waldur_site_load_historical_usage \
--config /etc/waldur/waldur-site-agent-config.yaml \
--offering-uuid 12345678-1234-1234-1234-123456789abc \
--user-token staff-user-api-token-here \
--start-date 2024-01-01 \
--end-date 2024-03-31
```
#### Command Parameters
- `--config`: Path to agent configuration file (same as regular usage reporting)
- `--offering-uuid`: UUID of the Waldur offering to load data for
- `--user-token`: **Staff user API token** (not the offering's regular API token)
- `--start-date`: Start date in YYYY-MM-DD format
- `--end-date`: End date in YYYY-MM-DD format
#### Processing Behavior
**Monthly Processing:**
- Historical usage is always processed **monthly** to align with Waldur's billing model
- Date ranges are automatically split into monthly billing periods
- Each month is processed independently for reliability and progress tracking
**Data Attribution:**
- Usage data is attributed to the first day of each billing month
- User usage includes both username and offering user URL when available
- Resource-level usage totals are calculated and submitted separately
**Error Handling:**
- Failed months are logged but don't stop processing of other months
- Individual user usage failures don't affect resource-level usage submission
- Progress is displayed: "Processing month 3/12: 2024-03"
### Usage Examples
#### Load Full Year of Data
```bash
# Load all of 2024
waldur_site_load_historical_usage \
--config /etc/waldur/waldur-site-agent-config.yaml \
--offering-uuid 12345678-1234-1234-1234-123456789abc \
--user-token your-staff-token \
--start-date 2024-01-01 \
--end-date 2024-12-31
```
#### Load Specific Quarter
```bash
# Load Q1 2024
waldur_site_load_historical_usage \
--config /etc/waldur/waldur-site-agent-config.yaml \
--offering-uuid 12345678-1234-1234-1234-123456789abc \
--user-token your-staff-token \
--start-date 2024-01-01 \
--end-date 2024-03-31
```
#### Load Single Month
```bash
# Load just January 2024
waldur_site_load_historical_usage \
--config /etc/waldur/waldur-site-agent-config.yaml \
--offering-uuid 12345678-1234-1234-1234-123456789abc \
--user-token your-staff-token \
--start-date 2024-01-01 \
--end-date 2024-01-31
```
### Monitoring Historical Loads
#### Progress Tracking
The command provides detailed progress information:
```text
🚀 Starting historical usage loading
📊 Will process 12 months of data
📅 Processing month 1/12: 2024-01
📋 Found 5 active resources to process
📊 Processing usage data for 5 accounts
📤 Submitted usage for resource project1_allocation: {'cpu': 15000, 'mem': 25000}
✅ Completed processing 2024-01 (5 resources)
📅 Processing month 2/12: 2024-02
...
🎉 Historical usage loading completed successfully!
Processed 12 months from 2024-01-01 to 2024-12-31
```
#### Log Files
For production use, redirect output to log files:
```bash
waldur_site_load_historical_usage \
--config /etc/waldur/waldur-site-agent-config.yaml \
--offering-uuid 12345678-1234-1234-1234-123456789abc \
--user-token your-staff-token \
--start-date 2024-01-01 \
--end-date 2024-12-31 \
> historical_load_2024.log 2>&1
```
### Troubleshooting Historical Loads
#### Error Messages and Solutions
**No Staff Privileges:**
```text
❌ Historical usage loading requires staff user privileges
```
- Solution: Use an API token from a user with `is_staff=True` in Waldur
**No Resources Found:**
```text
ℹ️ No active resources found for offering, skipping month
```
- Solution: Ensure resources exist in Waldur and have `backend_id` values set
**No Usage Data:**
```text
ℹ️ No usage data found for 2024-01
```
- Solution: Check SLURM accounting database has data for that period
- Verify SLURM account names match Waldur resource `backend_id` values
**Backend Not Supported:**
```text
❌ Backend does not support historical usage reporting
```
- Solution: Ensure you're using the SLURM backend and have updated code
#### Performance Considerations
**Large Date Ranges:**
- Historical loads can take hours for multi-year ranges
- Each month requires multiple API calls to Waldur
- SLURM database queries may be slow for old data
**Rate Limiting:**
- Waldur may rate limit API calls during bulk submission
- Consider adding delays between months if encountering 429 errors
**Database Impact:**
- Large historical queries may impact SLURM cluster performance
- Consider running during maintenance windows for multi-year loads
#### Validation and Verification
**Verify Data in Waldur:**
1. Check resource usage in Waldur marketplace
2. Verify billing calculations include historical periods
3. Confirm user-level usage attribution is correct
**Cross-Reference with SLURM:**
```bash
# Verify SLURM usage data matches what was submitted
sacct --accounts=project1_allocation \
--starttime=2024-01-01 \
--endtime=2024-01-31 \
--allocations \
--allusers \
--format=Account,ReqTRES,Elapsed,User
```
### Integration Notes
This setup is designed for **usage reporting only**. For a complete Waldur Site Agent deployment that includes:
- Order processing (resource creation/deletion)
- Membership synchronization
- Event processing
You would need additional agent instances or a multi-mode configuration with different service files for each mode.
**Historical Loading Integration:**
- Historical loading is a separate command, not part of regular agent operation
- Run historical loads **before** starting regular usage reporting to avoid conflicts
- Historical data submission requires staff tokens, regular reporting uses offering tokens

### Waldur Site Agent
# Waldur Site Agent
A stateless Python application that synchronizes data between Waldur Mastermind and service provider
backends. Manages account creation, usage reporting, and membership synchronization across different cluster
management systems.
## Architecture
The agent uses a **uv workspace architecture** with pluggable backends:
- **Core Package**: `waldur-site-agent` (base classes, common utilities)
- **Plugin Packages**: Standalone backend implementations under `plugins/` (see table below)
### Agent Modes
- `order_process`: Fetches orders from Waldur and manages backend resources
- `report`: Reports usage data from backend to Waldur
- `membership_sync`: Synchronizes user memberships
- `event_process`: Event-based processing using STOMP
## Usage
```bash
waldur_site_agent -m -c
```
## Logging
The agent emits structured logs in JSON format to stdout. This applies to both the core
agent and CLI tools.
Example log entry:
```json
{"event": "Running agent in order_process mode", "level": "info", "logger": "waldur_site_agent.backend", "timestamp": "2026-02-03T14:02:35.551020+00:00"}
```
### CLI Arguments
- `-m`, `--mode`: Agent mode (`order_process`, `report`, `membership_sync`, `event_process`)
- `-c`, `--config-file`: Path to configuration file
### Environment Variables
- `WALDUR_SITE_AGENT_ORDER_PROCESS_PERIOD_MINUTES`: Order processing period (default: 5)

### Croit S3 Storage Plugin for Waldur Site Agent
# Croit S3 Storage Plugin for Waldur Site Agent
This plugin provides integration between Waldur Mastermind and Croit S3 storage systems via RadosGW API.
Each marketplace resource automatically creates one S3 user with configurable safety limits.
## Features
- **Automatic S3 User Creation**: One S3 user per marketplace resource with slug-based naming
- **Usage-Based Billing**: Track actual storage and object consumption
- **Safety Quota Enforcement**: Optional bucket quotas based on user-specified limits
- **Usage Reporting**: Real-time storage and object count metrics
- **Credential Management**: S3 access keys exposed via resource metadata
- **Bearer Token Authentication**: Secure API access with configurable SSL verification
## Installation
Add the plugin to your UV workspace:
```bash
cd /path/to/waldur-site-agent
uv add ./plugins/croit-s3
```
## Configuration
### Basic Configuration
```yaml
offerings:
- name: "Croit S3 Object Storage"
waldur_api_url: "https://waldur.example.com/api/"
waldur_api_token: "your_waldur_api_token"
waldur_offering_uuid: "713c299671a14f5db9723a793291bc78"
# Event processing settings
stomp_enabled: true
websocket_use_tls: false
# Backend type
backend_type: "croit_s3"
# Croit S3-specific backend settings
backend_settings:
api_url: "https://192.168.240.34"
token: "your-bearer-token"
verify_ssl: false
user_prefix: "waldur_"

s3_storage:
accounting_type: "usage"
backend_name: "storage"
unit_factor: 1073741824 # Convert GB to bytes
enforce_limits: true
s3_objects:
accounting_type: "usage"
backend_name: "objects"
enforce_limits: true
```
### Configuration Options
#### Backend Settings
- **`api_url`** (required): Croit API base URL (will be appended with /api)
- **`token`** (optional): Bearer token for API authentication
- **`username`** (optional): API username (alternative to token)
- **`password`** (optional): API password (alternative to token)
- **`verify_ssl`** (optional, default: `true`): Enable/disable SSL certificate verification
- **`timeout`** (optional, default: `30`): Request timeout in seconds
- **`user_prefix`** (optional, default: `"waldur_"`): Prefix for generated usernames
- **`slug_separator`** (optional, default: `"_"`): Separator for slug components
- **`max_username_length`** (optional, default: `64`): Maximum username length
- **`default_tenant`** (optional): Default RadosGW tenant
- **`default_placement`** (optional): Default placement rule
- **`default_storage_class`** (optional): Default storage class
#### Component Types
##### Usage-Based Storage (`s3_storage`)
Tracks actual storage consumption with optional safety quota enforcement:
```yaml
s3_storage:
accounting_type: "usage"
backend_name: "storage"
unit_factor: 1073741824 # Bytes to GB conversion
enforce_limits: true # Apply safety limits from resource options as bucket quotas
```
##### Usage-Based Objects (`s3_objects`)
Tracks object count with optional safety quota enforcement:
```yaml
s3_objects:
accounting_type: "usage"
backend_name: "objects"
enforce_limits: true # Apply safety limits from resource options as object quotas
```
**Note**: The plugin automatically creates one S3 user per marketplace resource. No separate user component is needed.
## Username Generation
Usernames are automatically generated from Waldur resource metadata:
**Format**: `{prefix}{org_slug}_{project_slug}_{resource_uuid_short}`
**Example**: `waldur_myorg_myproject_12345678`
### Slug Cleaning Rules
- Convert to lowercase
- Replace non-alphanumeric characters with underscores
- Remove consecutive underscores
- Truncate if exceeds maximum length
- Preserve prefix and resource UUID
## Usage Reporting
The plugin collects usage metrics for all user buckets:
### Storage Usage
- Sums `usageSum.size` across all user buckets
- Converts bytes to configured units (e.g., GB)
- Reports actual storage consumption
### Object Usage
- Sums `usageSum.numObjects` across all user buckets
- Reports total object count
### Report Format
```json
{
"waldur_org_proj_12345678": {
"s3_storage": {"usage": 150},
"s3_objects": {"usage": 5000}
}
}
```
## Resource Metadata
Each S3 user resource exposes comprehensive metadata:
### S3 Credentials
```json
{
"s3_credentials": {
"access_key": "AKIAIOSFODNN7EXAMPLE",
"secret_key": "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY",
"endpoint": "https://192.168.240.34",
"region": "default"
}
}
```
### Storage Summary
```json
{
"storage_summary": {
"bucket_count": 3,
"total_size_bytes": 5368709120,
"total_objects": 1250,
"buckets": [
{
"name": "my-bucket",
"size_bytes": 1073741824,
"objects": 500
}
]
}
}
```
### Quota Information
```json
{
"quotas": {
"bucket_quota": {
"enabled": true,
"maxSize": 107374182400,
"maxObjects": 10000
},
"user_quota": {
"enabled": true,
"maxSize": 107374182400,
"maxObjects": 10000
}
}
}
```
## Safety Quota Enforcement
When `enforce_limits: true` is set for usage-based components, the plugin automatically applies safety limits from
resource options as RadosGW bucket quotas:
1. **Create Resource**: Apply initial quotas based on user-specified safety limits (storage_limit, object_limit)
2. **Prevent Overages**: Quotas act as safety nets to prevent unexpected usage charges
3. **Monitor Usage**: Include quota utilization in usage reports
### Quota Types
- **Storage Quota**: `maxSize` in bytes (converted from storage_limit in GB)
- **Object Quota**: `maxObjects` as integer count (from object_limit)
### How Safety Limits Work
1. **User Configuration**: Users set `storage_limit` and `object_limit` via Waldur marketplace form
2. **Resource Options**: Waldur passes these as resource attributes to the site agent
3. **Quota Application**: Plugin applies these as bucket quotas during S3 user creation
4. **Usage Billing**: Actual consumption is tracked and billed separately from quotas
## Waldur Marketplace Integration

}
```
## Testing
Run the test suite:
```bash
cd plugins/croit-s3
uv run pytest tests/ -v
```
## Development
### Adding New Components
1. Define component in site agent configuration:
```yaml
my_custom_component:
accounting_type: "usage"
backend_name: "custom_metric"
unit_factor: 1
enforce_limits: false
```
- Add usage collection logic in `_get_usage_report()`
- Add safety limit handling in `_apply_bucket_quotas()` if needed
- Add corresponding field in Waldur offering options for user input
### Error Handling
The plugin includes comprehensive error handling:
- **`CroitS3AuthenticationError`**: API authentication failures
- **`CroitS3UserNotFoundError`**: User doesn't exist
- **`CroitS3UserExistsError`**: User already exists
- **`CroitS3APIError`**: General API errors
- **`CroitS3Error`**: Base exception class
## Troubleshooting
### SSL Certificate Issues
```yaml
backend_settings:
verify_ssl: false # Disable for self-signed certificates
```
### Connection Timeouts
```yaml
backend_settings:
timeout: 60 # Increase timeout for slow networks
```
### Username Length Issues
```yaml
backend_settings:
max_username_length: 32 # Adjust for backend constraints
user_prefix: "w_" # Shorten prefix
```
### Debug Logging
Use standard Python logging configuration or waldur-site-agent logging settings to enable debug output for the plugin modules:
- `waldur_site_agent_croit_s3.client` - HTTP API interactions
- `waldur_site_agent_croit_s3.backend` - Backend operations
## Resource Lifecycle
1. **Order Creation**: User submits order with `storage_limit` and `object_limit`
2. **User Creation**: Plugin creates S3 user with slug-based username
3. **Quota Application**: Safety limits applied as bucket quotas
4. **Credential Exposure**: Access keys returned via resource metadata
5. **Usage Tracking**: Real-time storage and object consumption reporting
6. **Limit Updates**: Users can modify safety limits (creates new orders)
7. **Resource Deletion**: S3 user and all buckets are removed

### CSCS-DWDI Plugin for Waldur Site Agent
# CSCS-DWDI Plugin for Waldur Site Agent
This plugin provides integration with the CSCS Data Warehouse Data Intelligence (DWDI) system to report both
computational and storage usage data to Waldur. The plugin supports secure OIDC authentication and optional
SOCKS proxy connectivity for accessing DWDI API endpoints from restricted networks.
## Features
- **Dual Backend Support**: Separate backends for compute and storage resource usage reporting
- **OIDC Authentication**: Secure client credentials flow with automatic token refresh
- **Proxy Support**: SOCKS and HTTP proxy support for network-restricted environments
- **Flexible Configuration**: Configurable unit conversions and component mappings
- **Production Ready**: Comprehensive error handling and logging
## Overview
The plugin implements two separate backends to handle different types of accounting data:
- **Compute Backend** (`cscs-dwdi-compute`): Reports CPU and node hour usage from HPC clusters
- **Storage Backend** (`cscs-dwdi-storage`): Reports storage space and inode usage from filesystems
## Backend Types
### Compute Backend
The compute backend queries the DWDI API for computational resource usage and reports:
- Node hours consumed by accounts and users
- CPU hours consumed by accounts and users
- Account-level and user-level usage aggregation
**API Endpoints Used:**
- `/api/v1/compute/usage-month/account` - Monthly usage data
- `/api/v1/compute/usage-day/account` - Daily usage data
### Storage Backend
The storage backend queries the DWDI API for storage resource usage and reports:
- Storage space used (converted from bytes to configured units)
- Inode (file count) usage
- Path-based resource identification
**API Endpoints Used:**
- `/api/v1/storage/usage-month/filesystem_name/data_type` - Monthly storage usage
- `/api/v1/storage/usage-day/filesystem_name/data_type` - Daily storage usage

```
## Authentication
Both backends use OIDC client credentials flow for authentication with the DWDI API. The authentication tokens are
automatically managed with refresh capabilities.
### Required Settings
- `cscs_dwdi_client_id`: OIDC client identifier
- `cscs_dwdi_client_secret`: OIDC client secret
- `cscs_dwdi_oidc_token_url`: OIDC token endpoint URL
### Optional Settings
- `cscs_dwdi_oidc_scope`: OIDC scope (defaults to "openid")
### Token Management
- Tokens are automatically acquired and cached
- Automatic token refresh before expiration
- Error handling for authentication failures
## SOCKS Proxy Support
Both backends support SOCKS proxy for network connectivity. This is useful when the DWDI API is only accessible
through a proxy or jump host.
### SOCKS Proxy Configuration
Add the SOCKS proxy setting to your backend configuration:
```yaml
backend_settings:
# ... other settings ...
socks_proxy: "socks5://localhost:12345" # SOCKS5 proxy URL
```
### Supported Proxy Types
- **SOCKS5**: `socks5://hostname:port`
- **SOCKS4**: `socks4://hostname:port`
- **HTTP**: `http://hostname:port`
### Usage Examples
**SSH Tunnel with SOCKS5:**
```bash
# Create SSH tunnel to jump host
ssh -D 12345 -N user@jumphost.cscs.ch
# Configure backend to use tunnel
backend_settings:
socks_proxy: "socks5://localhost:12345"
```
**HTTP Proxy:**
```yaml
backend_settings:
socks_proxy: "http://proxy.cscs.ch:8080"
```
## Resource Identification
### Compute Resources
For compute resources, the system uses account names as returned by the DWDI API. The Waldur resource
`backend_id` should match the account name in the cluster accounting system.
### Storage Resources
For storage resources, there are two options:
1. **Direct Path Usage**: Set the Waldur resource `backend_id` to the actual filesystem path
2. **Path Mapping**: Use the `storage_path_mapping` setting to map resource IDs to paths
## Usage Reporting
Both backends are read-only and designed for usage reporting. They implement the `_get_usage_report()` method
but do not support:
- Account creation/deletion
- Resource management
- User management
- Limit setting
## Historical Usage Loading
The core `waldur_site_load_historical_usage` command can be used to bulk-load past usage data
from DWDI into Waldur. This requires implementing `get_usage_report_for_period()` on the
backend, which queries the same DWDI API endpoints but for a specific historical month instead
of the current one.
### Cluster Filtering
For compute backends, the normal reporting flow reads the cluster from each Waldur resource's
`offering_backend_id`. The historical loader does not pass Waldur resources, so you can
configure a cluster filter in `backend_settings`:
```yaml
backend_settings:
cscs_dwdi_cluster: "alps" # optional: filter historical queries by cluster
```
When set, all historical compute queries will include `cluster=["alps"]` in the API request.
If omitted, no cluster filter is applied.
### How It Works
The DWDI API already supports date-range queries (`from`/`to` parameters on
`/compute/usage-month/account` and `exact-month` on `/storage/usage-month`). The historical
loader calls `get_usage_report_for_period(resource_backend_ids, year, month)` for each month in
the requested range, then submits the returned usage to Waldur.
### Running Historical Loads
```bash
# Load compute usage for all of 2024
waldur_site_load_historical_usage \
--config /etc/waldur/cscs-dwdi-config.yaml \
--offering-uuid \
--user-token \
--start-date 2024-01-01 \
--end-date 2024-12-31 \
--no-staff-check
# Load resource-level totals only (skip per-user breakdown)
waldur_site_load_historical_usage \
--config /etc/waldur/cscs-dwdi-config.yaml \
--offering-uuid \
--user-token \
--start-date 2024-06-01 \
--end-date 2024-09-30 \
--no-staff-check \
--skip-user-usage
```
### CLI Flags
| Flag | Description |
|------|-------------|
| `--config` | Path to waldur-site-agent configuration file |
| `--offering-uuid` | UUID of the Waldur offering to load data for |
| `--user-token` | Waldur API token (staff or service provider) |
| `--start-date` | Start date in YYYY-MM-DD format |
| `--end-date` | End date in YYYY-MM-DD format |
| `--no-staff-check` | Skip staff user validation (use with service provider tokens) |
| `--skip-user-usage` | Only submit resource-level totals, skip per-user breakdown |
### Notes
- The `--no-staff-check` flag is useful when using a service provider token instead of a
staff token — the Waldur API enforces permissions server-side regardless
- The `--skip-user-usage` flag skips the `marketplace_offering_users_list` API call and all
per-user usage submission, which can significantly speed up large loads
- Resources must already exist in Waldur with valid `backend_id` values matching DWDI accounts
- Maximum date range is 5 years
## Example Configurations
See the `examples/` directory for complete configuration examples:
- `cscs-dwdi-compute-config.yaml` - Compute backend only
- `cscs-dwdi-storage-config.yaml` - Storage backend only
- `cscs-dwdi-combined-config.yaml` - Both backends in one configuration

## API Compatibility
This plugin is compatible with DWDI API version 1 (`/api/v1/`). It requires the following API endpoints to be available:
**Compute API:**
- `/api/v1/compute/usage-month/account`
- `/api/v1/compute/usage-day/account`
**Storage API:**
- `/api/v1/storage/usage-month/filesystem_name/data_type`
- `/api/v1/storage/usage-day/filesystem_name/data_type`
## Troubleshooting
### Authentication Issues
**Problem**: Authentication failures or token errors
**Solutions**:
- Verify OIDC client credentials are correct
- Check that the token endpoint URL is accessible
- Ensure the client has appropriate scopes for DWDI API access
- Verify network connectivity to the OIDC provider
- Check logs for specific authentication error messages
**Testing authentication**:
```bash
# Test OIDC token acquisition manually
curl -X POST "https://auth.cscs.ch/realms/cscs/protocol/openid-connect/token" \
-H "Content-Type: application/x-www-form-urlencoded" \
-d "grant_type=client_credentials&client_id=YOUR_CLIENT_ID&client_secret=YOUR_SECRET&scope=openid"
```
### Storage Backend Issues
**Problem**: Storage usage data not found or incorrect
**Solutions**:
- Verify `storage_filesystem` and `storage_data_type` match available values in DWDI
- Check `storage_path_mapping` if using custom resource IDs
- Ensure storage paths exist in the DWDI system
- Validate that the paths have usage data for the requested time period
### Connection Issues
**Problem**: Network connectivity or API access failures
**Solutions**:
- Use the `ping()` method to test API connectivity
- Check network connectivity to the DWDI API endpoint
- Verify SSL/TLS configuration and certificates
- If behind a firewall, configure SOCKS proxy (`socks_proxy` setting)
- Check DNS resolution for the API hostname
### Proxy Issues
**Problem**: SOCKS or HTTP proxy connection failures
**Solutions**:
- Verify proxy server is running and accessible
- Check proxy authentication if required
- Test proxy connectivity manually: `curl --proxy socks5://localhost:12345 https://dwdi.cscs.ch`
- Ensure proxy supports the required protocol (SOCKS4/5, HTTP)
- Verify proxy URL format is correct (e.g., `socks5://hostname:port`)
### Debugging Tips
**Enable debug logging**:
```python
import logging
logging.getLogger('waldur_site_agent_cscs_dwdi').setLevel(logging.DEBUG)
```
**Test API connectivity**:
```bash
# Test direct API access
curl -H "Authorization: Bearer YOUR_TOKEN" https://dwdi.cscs.ch/api/v1/
# Test through proxy
curl --proxy socks5://localhost:12345 -H "Authorization: Bearer YOUR_TOKEN" https://dwdi.cscs.ch/api/v1/
```

### CSCS HPC Storage Backend
# CSCS HPC Storage Backend
A Waldur Site Agent backend plugin for managing CSCS HPC Storage systems. This backend provides a REST API proxy to
access storage resource information from Waldur.
## Overview
The CSCS HPC Storage backend provides a REST API proxy that serves storage resource information from Waldur
Mastermind. The proxy translates Waldur resource data into CSCS-specific JSON format for consumption by external web
servers and storage management systems.
## Features
- **REST API Proxy**: Provides HTTP API access to storage resource information from Waldur
- **Multi-offering support**: Aggregates resources from multiple storage system offerings (capstor, vast, iopsstor)
- **Hierarchical storage structure**: Maps Waldur offering customer → resource customer → resource project to
storage tenant → customer → project
- **Configurable quotas**: Automatic inode quota calculation based on storage size
- **UNIX GID from Waldur API**: Fetches project Unix GID values from Waldur project metadata
- **GID caching**: Project GID values are cached in memory until server restart to reduce API calls
- **Configurable GID field**: Specify custom backend_metadata field name for Unix GID lookup
- **Mock data support**: Development/testing mode with generated target item data and fallback GID values
- **Flexible configuration**: Customizable file system types and quota coefficients
- **API Filtering**: Supports filtering by storage system, data type, status, and pagination
## Configuration
### Backend Settings
```yaml
backend_settings:
storage_file_system: "lustre" # Storage file system type
inode_soft_coefficient: 1.33 # Multiplier for soft inode limits
inode_hard_coefficient: 2.0 # Multiplier for hard inode limits
use_mock_target_items: false # Enable mock data for development
unix_gid_field: "unix_gid" # Field name in project backend_metadata for Unix GID (default: "unix_gid")
development_mode: false # Enable development mode with fallback mock GID values
```
### Backend Components
```yaml
backend_components:
storage:
measured_unit: "TB" # Storage unit (terabytes)
accounting_type: "limit" # Accounting type for quotas
label: "Storage" # Display label in Waldur
unit_factor: 1 # Conversion factor (TB to TB)
```
### Storage Systems Configuration
The storage proxy supports multiple storage systems through offering slug mapping:
```yaml
# Storage systems configuration - maps storage_system names to offering slugs
# The API will fetch resources from all configured offering slugs
storage_systems:
capstor: "capstor" # CAPSTOR storage system
vast: "vast" # VAST storage system
iopsstor: "iopsstor" # IOPSSTOR storage system
```

## Resource attributes
You can override defaults per resource using attributes passed from Waldur:
- `region` or `backend_region_id`
- `image` or `backend_image_id`
- `size` or `backend_size_id`
- `user_data` or `cloud_init`
- `ssh_key_id`, `ssh_key_fingerprint`, or `ssh_public_key`
- `ssh_key_name` (optional when using `ssh_public_key`)
- `tags` (list of strings)
If `ssh_public_key` is provided, the plugin will create the key in DigitalOcean
if it does not already exist.
## Resize via limits
To resize droplets from UPDATE orders, you can provide a size mapping:
```yaml
backend_settings:
size_mapping:
s-1vcpu-1gb:
cpu: 1
ram: 1024
disk: 25
```
When limits match an entry in `size_mapping`, the droplet will be resized to
the corresponding `size_slug`.

```bash
# Using uv (recommended)
uv sync --extra okd
# Or using pip
pip install -e plugins/okd
```
## Configuration
Create a configuration file (see `examples/okd-config.yaml` for a complete example):
```yaml
backend_type: okd
backend_settings:
api_url: https://api.okd.example.com:8443
token: your-service-account-token
verify_cert: true
namespace_prefix: waldur-
default_role: edit
backend_components:

accounting_type: limit
memory:
measured_unit: GB
accounting_type: limit
storage:
measured_unit: GB
accounting_type: limit
pods:
measured_unit: Count
accounting_type: limit
```
### Authentication Token Management
The plugin supports multiple authentication methods with automatic token refresh:
#### Static Token (Simple)
For testing or when manually managing tokens:
```yaml
backend_settings:
api_url: https://api.okd.example.com:8443
token: sha256~your-static-token-here
verify_cert: true
```
#### Service Account Token (Production Recommended)
For production deployments with automatic token refresh:
```yaml
backend_settings:
api_url: https://api.okd.example.com:8443
verify_cert: true
token_config:
token_type: service_account
service_account_path: /var/run/secrets/kubernetes.io/serviceaccount
```
#### File-Based Token Refresh
When tokens are managed by external systems:
```yaml
backend_settings:
api_url: https://api.okd.example.com:8443
verify_cert: true
token_config:
token_type: file
token_file_path: /etc/okd-tokens/current-token
```
#### OAuth Token Refresh (Future)
Framework ready for OAuth-based authentication:
```yaml
backend_settings:
api_url: https://api.okd.example.com:8443
verify_cert: true
token_config:
token_type: oauth
oauth_config:
client_id: your-oauth-client-id
client_secret: your-oauth-client-secret
refresh_token: your-refresh-token
token_endpoint: https://oauth.okd.example.com/oauth/token
```
## Waldur to OKD Object Mapping
The plugin maps Waldur organizational hierarchy to OKD/OpenShift projects and namespaces:
```mermaid
graph TB
subgraph "Waldur Hierarchy"
WC[Customer/Organization **Note:** The restore operation currently applies hardcoded default quotas rather than
> restoring previously configured values.
### User Access
Users from Waldur are automatically granted access to OKD projects through RoleBindings. The plugin
maps Waldur roles to OpenShift ClusterRoles for fine-grained access control.
## Testing
Run the plugin tests:
```bash
# Run all OKD plugin tests
uv run pytest plugins/okd/tests/
# Run specific test
uv run pytest plugins/okd/tests/test_okd_backend.py::TestOkdBackend::test_create_resource
```
## Troubleshooting
### Token Refresh Behavior
The plugin automatically handles token expiration and refresh:
- **Automatic Detection**: Monitors for 401/403 authentication errors
- **Refresh Triggers**: Automatically refreshes tokens before expiration (5 minutes buffer)
- **Fallback Handling**: Gracefully handles token refresh failures
- **Retry Logic**: Automatically retries failed requests with refreshed tokens
#### Token Refresh Flow
1. **Initial Request**: Uses current token for API calls
2. **Failure Detection**: Detects 401 Unauthorized responses
3. **Token Refresh**: Invalidates current token and loads new one
4. **Request Retry**: Retries the original request with the new token
5. **Error Handling**: Reports refresh failures with detailed error messages
### Authentication Issues
If authentication fails:
1. **Verify Token Validity**:
```bash
# Test token directly
curl -k -H "Authorization: Bearer YOUR_TOKEN" \
"https://your-okd-api:6443/api/v1"
```
2. **Check Token Expiration**:
```bash
# Decode JWT token (if using JWT format)
echo "YOUR_TOKEN" | cut -d'.' -f2 | base64 -d | jq .exp
```
3. **Validate Service Account Permissions**:
```bash
# Check if service account exists
oc get serviceaccount waldur-site-agent -n waldur-system
# Verify cluster role binding
oc get clusterrolebinding waldur-site-agent
```
### Connection Issues
If the agent cannot connect to the OKD cluster:
1. Verify the API URL is correct and accessible
2. Check the service account token is valid and not expired
3. For self-signed certificates, set `verify_cert: false`
4. Ensure network connectivity to the cluster
### Permission Errors
If operations fail with permission errors:
1. Verify the service account has the required ClusterRole permissions
2. Check the ClusterRoleBinding is correctly configured
3. Ensure the token has not expired (check logs for 401 errors)
4. Validate that the service account namespace exists
### Token Refresh Issues
If automatic token refresh fails:
1. **File-based tokens**: Ensure the token file path is readable and contains valid token
2. **Service account tokens**: Verify the service account path is mounted correctly
3. **Static tokens**: Replace expired static tokens manually
4. **OAuth tokens**: Check OAuth configuration and refresh token validity
### Debug Mode
Enable debug logging for detailed token management information:
```bash
# Set log level to DEBUG in configuration
log_level: DEBUG
# Or use environment variable
WALDUR_LOG_LEVEL=DEBUG waldur_site_agent -m order_process -c okd-config.yaml
```
### Diagnostics
Run diagnostics to verify configuration:
```bash
# Standard diagnostics
waldur_site_diagnostics -c okd-config.yaml
```

### OpenNebula Plugin for Waldur Site Agent
# OpenNebula Plugin for Waldur Site Agent
This plugin provides OpenNebula resource management for Waldur Site Agent.
It supports two independent offering modes:
- **VDC mode**: Virtual Data Centers with groups, quotas, networking, and
optional user account creation
- **VM mode**: Virtual Machines instantiated within an existing VDC, sized
by plan quotas with resize on plan switch
Each mode is configured as a separate Waldur offering with its own
`resource_type` setting.
## Features
### VDC Management
- **VDC Provisioning**: Each Waldur resource maps to one OpenNebula VDC + group
- **Quota Enforcement**: CPU, RAM, storage, and floating IP limits via group quotas
- **Usage Reporting**: Current resource usage from OpenNebula group quota counters
- **Idempotent Operations**: Create operations handle retries gracefully
(e.g. after connection resets)
- **User Account Creation** (optional): Creates an OpenNebula user with VDC
group membership, credentials displayed in Waldur Homeport via `backend_metadata`
- **Keycloak SAML Integration** (optional): Manages Keycloak groups per VDC
for SSO access to Sunstone — see the
[SAML Setup Guide](docs/saml-setup/index.md)
### VM Management
- **Plan-Based Sizing**: VM specs (vCPU, RAM, disk) come from Waldur plan quotas
(FIXED billing components), not from user-specified limits
- **VM Provisioning**: Instantiates VMs from templates within a parent VDC
- **VM Resize**: Plan switch triggers automatic resize (poweroff, resize
CPU/RAM, grow disk, resume)
- **SSH Key Injection**: Resolves SSH keys from Waldur service provider keys
- **Scheduling**: Optional `SCHED_REQUIREMENTS` for cluster placement
- **Usage Reporting**: Reports current VM allocation (vCPU, RAM, disk)
- **Independent Offering**: VM mode is a separate offering, not auto-created
### Networking (Optional)
When the Waldur offering includes networking configuration in `plugin_options`,
VDC creation automatically provisions:
- **VXLAN Network**: Internal tenant network with auto-allocated or
user-specified subnet
- **Virtual Router**: VNF appliance with internal + external NICs for NAT/DHCP
- **Security Groups**: Default inbound rules (SSH, ICMP, etc.)
- **Subnet Allocation**: Stateless next-available subnet allocation from a
configured pool
### Concept Mapping
| Waldur / OpenStack Concept | OpenNebula Equivalent | Auto-Created with VDC? |
|---|---|---|
| Tenant / Project | VDC + Group | Yes |
| Internal Network + Subnet | VXLAN VNet + Address Range | Yes (if configured) |
| Router + External Gateway | Virtual Router (VNF appliance) | Yes (if configured) |
| Security Group | Security Group | Yes (if rules provided) |
| Nova/Cinder/Neutron Quotas | Group Quotas | Yes |
| Floating IP | SDNAT4 via Virtual Router | Quota tracked, not auto-assigned |
## Installation
The OpenNebula plugin is included in the Waldur Site Agent workspace.
For general installation instructions, see the main
[Installation Guide](../../docs/installation.md).
### Dependencies
- **pyone** (>= 6.8.0): Python bindings for the OpenNebula XML-RPC API
- **OpenNebula** (>= 6.x): Target OpenNebula instance with XML-RPC enabled
- **VNF Appliance** (optional): Service Virtual Router template for networking
## Configuration
### VDC Offering Configuration
The agent YAML only needs API credentials. Component metadata
(`backend_components`) is automatically synced from the Waldur offering
at startup via `extend_backend_components()`.
```yaml
offerings:
- name: "OpenNebula VDC"
backend_type: "opennebula"
backend_settings:
api_url: "http://opennebula-host:2633/RPC2"
credentials: "oneadmin:password"
create_opennebula_user: true # optional: create ONE user per VDC
backend_components: {}
```
### VM Offering Configuration
VM offerings reference a parent VDC and a VM template. VM specs are
defined by Waldur plan quotas (FIXED components), not by resource limits.
```yaml
offerings:
- name: "OpenNebula VM"
backend_type: "opennebula"
backend_settings:
api_url: "http://opennebula-host:2633/RPC2"
credentials: "oneadmin:password"
resource_type: "vm"
parent_vdc_backend_id: "my-vdc-1"
template_id: 0
backend_components: {}
```
VM specs come from the Waldur plan's component quotas. Define plans with
FIXED billing components:
| Component | Description | Example values |
|---|---|---|
| `vcpu` | Virtual CPUs | Small: 1, Medium: 2, Large: 4 |
| `vm_ram` | Memory in MB | Small: 512, Medium: 2048, Large: 8192 |

`template_id`, `cluster_ids`, and `sched_requirements`.
### Waldur Offering Configuration
Infrastructure settings and user options are configured in the Waldur
offering, not in the agent YAML. This keeps secrets minimal on the agent
side and allows provider admins to manage infrastructure config from the
Waldur UI.
#### VDC Offering Components
Configured by the provider in the Waldur offering. Defines the resource
limits available to users.
```yaml
components:
cpu:
measured_unit: "cores"
unit_factor: 1
accounting_type: "limit"
ram:
measured_unit: "MB"
unit_factor: 1
accounting_type: "limit"
storage:
measured_unit: "MB"
unit_factor: 1
accounting_type: "limit"
floating_ip:
measured_unit: "IPs"
unit_factor: 1
accounting_type: "limit"
```
#### VM Offering Components
VM offerings use FIXED billing components. The component keys define
which values the agent reads from plan quotas. No `unit_factor` is
needed (default 1).
```yaml
components:
vcpu:
measured_unit: "cores"
accounting_type: "fixed"
vm_ram:
measured_unit: "MB"
accounting_type: "fixed"
vm_disk:
measured_unit: "MB"
accounting_type: "fixed"
```
#### Offering Plugin Options (Networking)
Set in the Waldur offering's `plugin_options`. Flows to the agent via
`waldur_resource.offering_plugin_options`. Required only if networking
should be auto-provisioned with VDC creation.
```yaml
plugin_options:
zone_id: 0
cluster_ids: [0, 100]
external_network_id: 10
vxlan_phydev: "eth0"
virtual_router_template_id: 8
default_dns: "8.8.8.8"
internal_network_base: "10.0.0.0"
internal_network_prefix: 8
subnet_prefix_length: 24
security_group_defaults:
- direction: "INBOUND"
protocol: "TCP"
range: "22:22"
- direction: "INBOUND"
protocol: "ICMP"
type: "8"
```
| Key | Required | Default | Description |
|---|---|---|---|
| `external_network_id` | Yes* | - | Provider network ID for router uplink |
| `virtual_router_template_id` | Yes* | - | VNF appliance VM template ID |
| `zone_id` | No | `0` | OpenNebula zone for VNet/VDC assignment |
| `cluster_ids` | No | `[]` | Clusters for VNet/VM placement |
| `vxlan_phydev` | No | `eth0` | Physical interface for VXLAN tunnels |
| `default_dns` | No | `8.8.8.8` | DNS server for tenant networks |
| `internal_network_base` | No | `10.0.0.0` | Base address for subnet pool |
| `internal_network_prefix` | No | `8` | Prefix length of the subnet pool |
| `subnet_prefix_length` | No | `24` | Prefix length per tenant subnet |
| `security_group_defaults` | No | `[]` | Default inbound rules for new VDCs |
| `sched_requirements` | No | - | ONE scheduling expression for VMs/VRs |
*Required for networking. If `external_network_id` or
`virtual_router_template_id` is absent, VDCs are created without networking.
#### Offering Order Options (User Inputs)
Optional fields presented to users at order time. Flows to the agent via
`waldur_resource.attributes`.
```yaml
options:
order:
- key: "subnet_cidr"
label: "Internal Subnet CIDR"
type: "string"
required: false
- key: "ssh_public_key"
label: "SSH Public Key"
type: "string"
required: false
```
| Key | Description |
|---|---|
| `subnet_cidr` | User-specified subnet (e.g. `192.168.50.0/24`). Auto-allocated if empty. |
| `ssh_public_key` | SSH public key or Waldur SSH key UUID. Injected into VMs. |

### 1.3 Configure Group Membership Mapper
Add a SAML protocol mapper to include group membership in the assertion:
| Setting | Value |
|---------|-------|
| Mapper Type | Group list |
| Name | `member` |
| SAML Attribute Name | `member` |
| Full group path | ON |
| Single Group Attribute | ON |
### 1.4 Create Test Users
Create users in the `opennebula` realm (e.g., `testuser1`, `admin1`). Set passwords for each.
### 1.5 Create an Admin Service Account
The site-agent needs admin access to the Keycloak API.
Use the built-in `admin` user in the `master` realm,
or create a dedicated service account with group management permissions.
[Image: Keycloak Groups]
*Keycloak admin console showing VDC groups created by the site-agent*
## Step 2: Configure OpenNebula SAML Auth Driver
### 2.1 Edit `/etc/one/auth/saml_auth.conf`
```yaml
:sp_entity_id: 'opennebula-sp'
:acs_url: 'https:///fireedge/api/auth/acs'
:identity_providers:
:keycloak:
:issuer: 'https:///keycloak/realms/opennebula'
:idp_cert: ''
:user_field: 'NameID'
:group_field: 'member'
:mapping_generate: false
:mapping_key: 'SAML_GROUP'
:mapping_mode: 'keycloak'
:mapping_timeout: 300
:mapping_filename: 'keycloak_groups.yaml'
:mapping_default: 1
```
Key settings:
- **`mapping_generate: false`** — the site-agent manages the mapping file, not OpenNebula
- **`mapping_key: 'SAML_GROUP'`** — matches the template attribute set on ONE groups
- **`mapping_mode: 'keycloak'`** — uses Keycloak group paths for matching
- **`mapping_filename`** — must match `saml_mapping_file` in the agent config
### 2.2 Get the IDP Certificate
Export the signing certificate from Keycloak:
- Realm Settings > Keys > RS256 > Certificate
Or fetch from the SAML metadata endpoint:
```text
https:///keycloak/realms/opennebula/protocol/saml/descriptor
```
## Step 3: Configure the Site Agent
### 3.1 Agent Configuration
```yaml
offerings:
- name: "opennebula-vdc"
uuid: ""
backend_type: "opennebula"
backend:
api_url: "http://:2633/RPC2"
credentials: "oneadmin:"
zone_id: 0
cluster_ids: [0, 100]
resource_type: "vdc"
# Keycloak SAML integration
keycloak_enabled: true
keycloak:
keycloak_url: "https:///keycloak/"
keycloak_realm: "opennebula"
keycloak_user_realm: "master"
client_id: "admin-cli"
keycloak_username: "admin"
keycloak_password: ""
keycloak_ssl_verify: true
# Must match mapping_filename in saml_auth.conf
saml_mapping_file: "/var/lib/one/keycloak_groups.yaml"
# Default role when adding users without explicit role
default_user_role: "user"
components:
cpu:
type: "cpu"
name: "CPU Cores"
measured_unit: "cores"
billing_type: "limit"
unit_factor: 1
ram:
type: "ram"
name: "RAM"
measured_unit: "MB"
billing_type: "limit"
unit_factor: 1
storage:
type: "storage"
name: "Storage"
measured_unit: "MB"
billing_type: "limit"
unit_factor: 1
```
See [`examples/opennebula-config-saml.yaml`](../../examples/opennebula-config-saml.yaml) for a complete example.
### 3.2 VDC Roles (Optional)
The default roles are `admin`, `user`, and `cloud`. Each role creates:
- A Keycloak child group under `vdc_{slug}/{role_name}`
- An OpenNebula group `{slug}-{suffix}` with SAML_GROUP and FIREEDGE template attributes
Override defaults in `backend_settings.vdc_roles`:
```yaml
vdc_roles:
- name: "admin"
one_group_suffix: "admins"
default_view: "groupadmin"
views: "groupadmin,user,cloud"
group_admin: true
- name: "user"
one_group_suffix: "users"
default_view: "user"
views: "user"
- name: "cloud"
one_group_suffix: "cloud"
default_view: "cloud"
views: "cloud"
```
## Step 4: Create the OpenNebula VDC Offering in Waldur
### 4.1 Register the Organization as a Service Provider
Navigate to **Organizations** and select the organization that will provide
the OpenNebula VDC service. Go to the **Edit** tab and click
**Service provider** in the sidebar.
If the organization is not yet registered as a service provider,
click **Enable service provider profile**.
[Image: Service Provider Tab]
*Organization settings showing the Service provider configuration*
### 4.2 Create the VDC Offering
Switch to the **Service provider** tab at the top, then navigate to
**Marketplace > Offerings**. Click **Add** to create a new offering.
[Image: Provider Dashboard]
*Service provider dashboard showing active offerings and resources*
In the creation dialog, fill in:
| Field | Value |
|-------|-------|
| Name | `OpenNebula VDC` |
| Category | `Private Clouds` (or create a new VDC-specific category) |
| Type | `Waldur site agent` |
[Image: Create Offering]
*New offering dialog with name, category, and type selected*
### 4.3 Configure Offering Details
After creation, you'll be taken to the offering editor.
The offering UUID shown in the URL is what you'll use in the
site-agent config (`waldur_offering_uuid`).
[Image: Offering Created]
*Offering editor showing the newly created OpenNebula VDC offering in Draft state*
### 4.4 Add the Sunstone Endpoint
Navigate to **Public information > Endpoints** and click **Add endpoint**.
This endpoint will be displayed to users on the offering page,
giving them a direct link to the OpenNebula Sunstone UI.
| Field | Value |
|-------|-------|
| Name | `OpenNebula Sunstone` |
| URL | `https://lab-1910.opennebula.cloud` (your Sunstone URL) |
[Image: Add Endpoint]
*Adding the Sunstone endpoint URL*
[Image: Endpoint Added]
*Endpoint successfully added to the offering*
### 4.5 Load Accounting Components from the Site Agent
Components (CPU, RAM, Storage) are defined in the site agent configuration
under `backend_components`. Use `waldur_site_load_components` to push them
into Waldur:
```bash
waldur_site_load_components -c opennebula-saml-agent-config.yaml
```
This creates the offering components with the correct types, units, and
limits. Then create plans (e.g., Small VDC, Medium VDC) via the
**Accounting** tab in the offering editor.
### 4.6 Activate the Offering
Once the offering is configured, click **Activate** to publish it to the
marketplace. Users will then be able to order VDCs through the Waldur
self-service portal.
## Step 5: End-to-End Walkthrough
This section demonstrates the complete flow from ordering a VDC in Waldur to logging in to Sunstone.
### 5.1 Site Agent Configuration
Create a configuration file for the site agent that matches the offering
created in Step 4. The key fields are `waldur_offering_uuid`
(from the offering URL) and the `keycloak` settings.
See [`opennebula-saml-agent-config.yaml`](opennebula-saml-agent-config.yaml) for the full example.
### 5.2 Order a VDC in the Marketplace
Navigate to **Marketplace** in Waldur and find the "OpenNebula VDC" offering. Click **Add resource**.
[Image: Marketplace]
*OpenNebula VDC offering visible in the marketplace*
Fill in the order form:
- **Organization**: Select your organization
- **Project**: Select or create a project (e.g., "OpenNebula SAML Demo")
- **Plan**: Select a plan (e.g., "Small VDC")
- **Allocation name**: Enter a name for the VDC (e.g., `demo-saml-vdc`)
[Image: Order Form]
*Order form with project, plan, and allocation name filled in*
Click **Create** and confirm. The order will be placed in `pending-provider` state.
[Image: Order Submitted]
*Order submitted and awaiting site agent processing*
### 5.3 Process the Order with the Site Agent
Start the site agent (or let the polling loop run). The agent will:
1. Poll Waldur for pending orders
2. Approve the order
3. Create the VDC + group in OpenNebula
4. Create Keycloak groups (`vdc_{name}/admin`, `vdc_{name}/user`, `vdc_{name}/cloud`)
5. Create ONE groups with SAML templates
6. Update the SAML mapping file
7. Set the backend ID and mark the order as done
```bash
# Process orders (creates VDCs, Keycloak groups, SAML mappings)
waldur_site_agent -m order_process -c opennebula-saml-agent-config.yaml
# Sync user memberships (adds/removes users from Keycloak groups)
waldur_site_agent -m membership_sync -c opennebula-saml-agent-config.yaml
```
**Example output** from a successful order processing run:
```text

[Image: Resource Created]
*VDC resource created and visible in the project*
### 5.4 Add a Keycloak User to the Project
Add a user (who exists in Keycloak) to the Waldur project as a member.
This can be done via the project's **Team** tab or via the API.
On the next membership sync cycle, the site agent will call `add_user()`
which adds the user to the correct Keycloak group (`vdc_{name}/user`).
```bash
# Run membership sync (typically on a schedule or as a separate agent instance)
waldur_site_agent -m membership_sync -c opennebula-saml-agent-config.yaml
```
**Example output** from membership sync:
```text
INFO: Processing offering OpenNebula VDC (6a0a1626-...)
INFO: Syncing user list for resource demo-saml-vdc
INFO: Adding user testuser1 to VDC demo-saml-vdc with role user
INFO: Added user 0f329cb6-... to group 2efcd37b-...
INFO: Added user testuser1 to Keycloak group vdc_demo-saml-vdc/user
```
### 5.5 Verify Sunstone Access
After the site agent syncs the membership, the user can log in to Sunstone
via SAML. The group switcher will now show the new VDC alongside any
existing ones.
[Image: Three VDCs in Sunstone]
*testuser1 can see three VDC groups after being added to a new project*
## Step 6: Verify the Integration
### 6.1 Sunstone Login Page
Navigate to Sunstone. The login page shows a "Sign In with SAML service" link at the bottom.
[Image: Sunstone Login]
### 6.2 Keycloak SAML Login
Clicking the SAML link redirects to the Keycloak login page for the `opennebula` realm.
[Image: Keycloak SAML Login]
### 6.3 Sunstone Dashboard
After successful SAML login, the user lands on the Sunstone dashboard with the correct FireEdge view matching their role.
[Image: Sunstone Dashboard]
### 6.4 Group Switcher
Users assigned to multiple VDCs can switch between them using the group switcher in the top bar.
[Image: Group Switcher]
*testuser1 can see both `vdc-demo-users` and `e2e-saml-test-users` groups*
## How It Works
### VDC Creation
When the site-agent creates a VDC with `keycloak_enabled: true`:
1. Creates the OpenNebula VDC, base group, and clusters (standard flow)
2. Creates a Keycloak parent group `vdc_{slug}`
3. Creates Keycloak child groups `admin`, `user`, `cloud` under the parent
4. Creates OpenNebula groups `{slug}-admins`, `{slug}-users`, `{slug}-cloud`
5. Sets `SAML_GROUP` and `FIREEDGE` template attributes on each ONE group
6. Adds all ONE groups to the VDC
7. Writes the mapping file (`keycloak_groups.yaml`) with KC group path -> ONE group ID entries
### User Management
When a user is added to a Waldur project that has a VDC:
1. Site-agent calls `add_user(resource, username, role="user")`
2. Finds the user in Keycloak by username
3. Adds the user to the `vdc_{slug}/user` Keycloak group
4. On next SAML login, OpenNebula reads the SAML assertion's `member` attribute
5. Matches the Keycloak group path against `keycloak_groups.yaml`
6. Places the user in the corresponding ONE group with the correct FireEdge view
### VDC Deletion
When a VDC is terminated:
1. Deletes ONE SAML groups (`{slug}-admins`, `{slug}-users`, `{slug}-cloud`)
2. Deletes Keycloak child groups, then parent group
3. Removes entries from the mapping file
4. Deletes the VDC and base group (standard flow)
## SAML Mapping File Format
The mapping file is a YAML dictionary mapping Keycloak group paths to OpenNebula group IDs:
```yaml
---
"/vdc_demo/admin": "202"
"/vdc_demo/user": "203"
"/vdc_demo/cloud": "204"
"/vdc_my-project/admin": "210"
"/vdc_my-project/user": "211"
"/vdc_my-project/cloud": "212"
```
The site-agent writes this file atomically (via temp file + rename) and merges new entries with existing ones.
## Running Integration Tests
```bash
OPENNEBULA_INTEGRATION_TESTS=true \
OPENNEBULA_API_URL="http://:2633/RPC2" \
OPENNEBULA_CREDENTIALS="oneadmin:" \
OPENNEBULA_CLUSTER_IDS="0,100" \
KEYCLOAK_URL="https:///keycloak/" \
KEYCLOAK_REALM="opennebula" \
KEYCLOAK_ADMIN_USERNAME="admin" \
KEYCLOAK_ADMIN_PASSWORD="" \
KEYCLOAK_TEST_USERNAME="testuser1" \
uv run pytest plugins/opennebula/tests/test_saml_integration_e2e.py -v
```
The integration test suite (`test_saml_integration_e2e.py`) runs 21 ordered tests covering the full lifecycle:
| # | Test | Verifies |
|---|------|----------|
| 01 | Connectivity | ONE + Keycloak reachable |
| 02 | Keycloak init | Client created successfully |
| 03 | Create VDC | VDC + KC groups + ONE groups created |
| 04-06 | KC groups | Parent + 3 children exist |
| 07-09 | ONE groups | SAML_GROUP template, FIREEDGE views, VDC membership |
| 10 | Mapping file | Contains correct entries |
| 11 | Quotas | VDC quotas set |
| 12-13 | Add user | User in correct KC group (user + admin roles) |
| 14 | Remove user | User removed from all role groups |
| 15 | User not found | BackendError raised |
| 16-20 | Delete VDC | Full cleanup (KC groups, ONE groups, mappings, VDC) |
| 21 | Idempotent | Second create reuses existing groups |
## Troubleshooting
### SAML login fails with "Invalid credentials"
- Verify the user exists in the Keycloak `opennebula` realm (not `master`)
- Check that the user has a password set
### User doesn't see the correct VDC after login
- Check that the user is in the correct Keycloak group (`vdc_{slug}/{role}`)
- Verify the mapping file on the ONE server contains the correct entries
- Check that the ONE group has `SAML_GROUP` set: `onegroup show `
- The `mapping_timeout` in `saml_auth.conf` controls how often the mapping file is re-read (default 300s)
### Keycloak client init fails with 401
- The `keycloak_user_realm` must be set to `master` if the admin user is in the master realm
- Verify admin credentials work: `curl -X POST .../realms/master/protocol/openid-connect/token`
### Groups created but user not mapped
- Ensure `mapping_generate: false` in `saml_auth.conf`
- Ensure `mapping_key: 'SAML_GROUP'` matches the template attribute name
- Ensure `mapping_mode: 'keycloak'` is set
- Check that the SAML client has a "Group list" protocol mapper with attribute name `member`

### Waldur Site Agent - Rancher Plugin
# Waldur Site Agent - Rancher Plugin
This plugin enables integration between Waldur Site Agent and Rancher for Kubernetes project management with optional
Keycloak user group integration.
## Features
- **Rancher Project Management**: Creates and manages Rancher projects with resource-specific naming
- **OIDC Group Integration**: Creates hierarchical Keycloak groups that map to Rancher project roles via OIDC
- **Automatic User Management**: Adds/removes users from Keycloak groups based on Waldur project membership
- **Resource Quotas**: Sets CPU and memory limits as Rancher project quotas
- **Usage Reporting**: Reports actual allocated resources (CPU, memory, storage) from Kubernetes
- **Complete Lifecycle**: Creates groups, binds to projects, manages users, cleans up empty groups
- **Enhanced Descriptions**: Project descriptions include customer and project names for clarity
## Architecture
The plugin follows the Waldur Site Agent plugin architecture and consists of:
- **RancherBackend**: Main backend implementation that orchestrates project and user management
- **RancherClient**: Handles Rancher API operations for project management
- **KeycloakClient**: Manages Keycloak groups and user memberships
### Key Architecture Features
- **Resource-Specific Naming**: Rancher projects named after resource slugs for better identification
- **OIDC-Based Access**: No direct user-to-Rancher assignments; all access via Keycloak groups
- **Enhanced Backend Interface**: Full `WaldurResource` context available to all backend methods
- **Automatic Cleanup**: Empty groups and role bindings automatically removed
- **Real-World Validated**: Tested with actual Rancher and Keycloak instances
## Installation
1. Install the plugin using uv:
```bash
uv sync --all-packages
```

## Usage
### Running the Agent
Start the agent with your configuration file:
```bash
uv run waldur_site_agent -c rancher-config.yaml -m order_process
```
### Diagnostics
Run diagnostics to check connectivity:
```bash
uv run waldur_site_diagnostics -c rancher-config.yaml
```
### Supported Agent Modes
- **order_process**: Creates and manages Rancher projects based on Waldur resource orders
- **membership_sync**: Synchronizes user memberships between Waldur and Rancher/Keycloak
- **report**: Reports resource usage from Rancher projects to Waldur
## Project Management
### Project Creation
When a Waldur resource (representing project access) is created:
1. A Rancher project is created with the name `{project_prefix}{waldur_project_slug}`
2. If Keycloak is enabled, hierarchical groups are created:
- **Parent Group**: `c_{cluster_uuid_hex}` (cluster-level access)
- **Child Group**: `project_{project_uuid_hex}_{role_name}` (project + role access)
3. Resource quotas are applied to the Rancher project
4. OIDC binds the Keycloak groups to Rancher project roles
### User Management
When users are added to a Waldur resource:
1. User is added to the Rancher project with the configured role
2. If Keycloak is enabled, user is added to the child group (`project_{project_uuid_hex}_{role_name}`)
3. OIDC automatically grants the user access to the Rancher project based on group membership
When users are removed:
1. User is removed from the Rancher project
2. If Keycloak is enabled, user is removed from the project role group
### Naming Convention
The plugin follows the waldur-mastermind Rancher plugin naming patterns:
- **Rancher Project Name**: `{project_prefix}{waldur_resource_slug}` (configurable prefix)
- **Keycloak Parent Group**: `c_{cluster_uuid_hex}` (cluster access)
- **Keycloak Child Group**: `project_{project_uuid_hex}_{role_name}` (project + role access)
Where:
- `{project_prefix}` is configurable (default: `waldur-`)
- `{waldur_resource_slug}` is the Waldur resource slug (more specific than project slug)
- `{cluster_uuid_hex}` is the cluster UUID in hex format
- `{project_uuid_hex}` is the Waldur project UUID in hex format (for permissions)
- `{role_name}` is configurable (default: `workloads-manage`)
## Supported Components and Accounting Model
The plugin supports the following resource components (all with `billing_type: "limit"`):
- **CPU**: Measured in cores
- **Memory**: Measured in GB
- **Storage**: Measured in GB
### Accounting Model
**Project Limits (Quotas)**:
- Only **CPU and memory limits** are set as Rancher project quotas
- Storage is not enforced as quotas (reported only)
**Usage Reporting** (for all components):
All components report **actual allocated resources**:
- **CPU**: Sum of all container CPU requests in the project
- **Memory**: Sum of all container memory requests in the project
- **Storage**: Sum of all persistent volume claims in the project
### Accounting Flow
1. **Project Creation**: CPU and memory limits → Rancher project quotas
2. **Usage Reporting**: All components → actual allocated resources from Kubernetes
## Complete Workflow
The plugin provides end-to-end automation for Rancher project and user management:
### Order Processing
1. **Order Detection**: Monitors Waldur for new resource orders
2. **Project Creation**: Creates Rancher project named `{prefix}{resource_slug}`
3. **Enhanced Descriptions**: Includes customer and project context
4. **Quota Management**: Sets CPU and memory limits if specified
5. **OIDC Setup**: Creates and binds Keycloak groups to project roles
### Membership Sync
1. **User Detection**: Monitors Waldur for user membership changes
2. **Group Management**: Creates missing Keycloak groups if needed
3. **User Addition**: Adds users to appropriate Keycloak groups
4. **User Removal**: Removes users when removed from Waldur projects
5. **Cleanup**: Removes empty groups and their Rancher role bindings
### OIDC Integration Flow
1. **Keycloak Groups**: `c_{cluster_hex}` (parent) → `project_{project_slug}_{role}` (child)
2. **Group Binding**: `keycloakoidc_group://{group_name}` bound to Rancher project role
3. **User Management**: Users added to Keycloak groups only (not directly to Rancher)
4. **Automatic Access**: OIDC grants Rancher project access based on group membership
## Error Handling
- Rancher connectivity issues will be logged and retried
- Keycloak failures will be logged but won't stop Rancher operations
- Invalid configurations will be detected during diagnostics
- Missing users in Keycloak will be logged as warnings
## Development
### Running Tests
```bash
uv run pytest plugins/rancher/tests/
```
### Code Quality
```bash
pre-commit run --all-files
```
## Troubleshooting
### Common Issues
#### 1. Order Processing Disabled
```text
Order processing is disabled for offering X, skipping it
```
**Solution**: Add backend configuration to your offering:
```yaml
order_processing_backend: "rancher"
membership_sync_backend: "rancher"
reporting_backend: "rancher"
```
#### 2. Rancher Authentication Fails (401 Unauthorized)
```text
401 Client Error: Unauthorized for url: https://rancher.../v3
```
**Solutions**:
- Verify access key and secret key are correct
- Ensure token is **unscoped** (not cluster-specific)
- Check token hasn't expired
- Verify API URL format: `https://your-rancher.com` (without `/v3`)
#### 3. Keycloak Connection Fails (404)
```text
404: "Unable to find matching target resource method"
```
**Solutions**:
- Verify Keycloak URL (try with/without `/auth/` suffix)
- Check realm name is correct
- Ensure user exists in the specified realm
#### 4. Keycloak Group Creation Fails (403 Forbidden)
```text
403: "HTTP 403 Forbidden"
```
**Solution**: Grant user `manage-users` role:
- **Realm**: Select target realm
- **Users** → Your service user
- **Role Mappings** → **Client Roles** → `realm-management`
- **Add**: `manage-users`
#### 5. Cluster ID Format Error
```text
Cluster not found or invalid cluster ID
```
**Solution**: Use correct format:
- ✅ **Correct**: `c-j8276` (cluster ID only)
- ❌ **Incorrect**: `c-j8276:p-xxxxx` (project reference)
#### 6. Component Loading Fails
```text
KeyError: 'accounting_type'
```
**Solution**: Use correct component format:
```yaml
backend_components:
cpu:
type: "cpu"
measured_unit: "cores"
accounting_type: "limit" # Not billing_type
label: "CPU Cores"
unit_factor: 1
```
### Logging
Enable debug logging to see detailed operation logs:
```yaml
logging:
level: DEBUG
```
### Diagnostic Commands
Run comprehensive diagnostics:
```bash
uv run waldur_site_diagnostics -c your-config.yaml
```
This will test:
- Rancher API connectivity and authentication
- Keycloak connectivity and permissions (if enabled)
- Project listing capabilities
- Backend discovery and initialization
- Component configuration validity
### Verification Commands
Test individual components:
```bash
# Test Rancher connection
curl -u "token-xxxxx:secret-key" "https://your-rancher.com/v3"
# Test Keycloak realm access
curl "https://your-keycloak.com/auth/admin/realms/your-realm" \
-H "Authorization: Bearer $(get-keycloak-token)"
# List Rancher projects in cluster
curl -u "token-xxxxx:secret-key" \
"https://your-rancher.com/v3/projects?clusterId=c-xxxxx"
```

### SLURM Plugin for Waldur Site Agent
# SLURM Plugin for Waldur Site Agent
The SLURM plugin provides SLURM cluster management capabilities for Waldur Site Agent,
including resource management, usage reporting, periodic limits, and historical data loading.
## Features
### Core SLURM Management
- **Account Management**: Create, delete, list, and manage SLURM accounts
- **User Association**: Add/remove users from SLURM accounts with automatic association management
- **Resource Limits**: Set and manage CPU, memory, GPU, and custom TRES limits
- **Usage Reporting**: Real-time usage data collection and reporting to Waldur
- **Health Monitoring**: Cluster status checking and connectivity validation
### Periodic Limits System
- **Dynamic Fairshare**: Automatic fairshare adjustments based on usage patterns
- **TRES Limits**: GrpTRESMins, MaxTRESMins, and GrpTRES limit management
- **QoS Management**: Threshold-based Quality of Service adjustments
- **Carryover Allocation**: Unused allocation carryover between billing periods
- **Decay Calculations**: Configurable half-life decay for historical usage
- **Event-Driven Updates**: Real-time periodic limits updates via STOMP
### Historical Usage Loading
The `waldur_site_load_historical_usage` command has been moved to the core package and is now
available to all backend plugins. The SLURM backend implements `get_usage_report_for_period()`
to supply historical data from SLURM accounting records.
### Dual-Mode Operation
- **Production Mode**: Direct SLURM cluster integration via `sacctmgr` and `sacct`
- **Emulator Mode**: Development and testing with SLURM emulator integration
- **Seamless Switching**: Configuration-driven mode selection
## Installation
The SLURM plugin is included in the main Waldur Site Agent installation. For specific
installation instructions, see the main [Installation Guide](../../docs/installation.md).
### Dependencies
- **SLURM Tools**: `sacctmgr`, `sacct` commands available on cluster head node
- **Python Packages**: Automatically installed with the plugin
- **Optional**: SLURM emulator for development and testing
## Configuration
### Basic Configuration
```yaml
offerings:
- name: "My SLURM Cluster"
backend_type: "slurm"
backend_settings:
# Core SLURM account management
default_account: "root"
customer_prefix: "waldur_"
project_prefix: "waldur_"
allocation_prefix: "waldur_"
backend_components:
cpu:
unit: "k-Hours"
unit_factor: 60000
mem:
unit: "GB-Hours"
unit_factor: 61440
gpu:
unit: "GPU-Hours"
unit_factor: 60
```
### Periodic Limits Configuration
```yaml
backend_settings:
# Periodic limits system
periodic_limits:
enabled: true
emulator_mode: false # true for development
emulator_base_url: "http://localhost:8080"
# Limit type: GrpTRESMins, MaxTRESMins, or GrpTRES
limit_type: "GrpTRESMins"
# TRES billing configuration
tres_billing_enabled: true
tres_billing_weights:
cpu: 1.0 # 1 CPU-hour = 1 billing unit
mem: 0.1 # 10 GB-hours = 1 billing unit
gpu: 10.0 # 1 GPU-hour = 10 billing units
# QoS management
qos_levels:
default: "normal"
slowdown: "slowdown"
blocked: "blocked"
```
### Event Processing Configuration
```yaml
# Event processing for real-time periodic limits
event_processing:
enabled: true
stomp_settings:
host: "mastermind.example.com"
port: 61613
username: "site_agent"
password: "${STOMP_PASSWORD}"
# Subscribe to periodic limits updates
observable_object_types:
- "RESOURCE_PERIODIC_LIMITS_UPDATE"
```
## Usage
### Basic Agent Operations
```bash
# Resource management mode
uv run waldur_site_agent -m order_process -c config.yaml
# Usage reporting mode
uv run waldur_site_agent -m report -c config.yaml
# User synchronization mode
uv run waldur_site_agent -m membership_sync -c config.yaml
# Event processing mode (for periodic limits)
uv run waldur_site_agent -m event_process -c config.yaml
```
### Loading Historical Usage
```bash
# Load historical data for specific date range
uv run waldur_site_load_historical_usage \
--config /etc/waldur/config.yaml \
--offering-uuid 12345678-1234-1234-1234-123456789abc \
--user-token staff-user-api-token \
--start-date 2024-01-01 \
--end-date 2024-12-31
```
**Requirements for historical loading:**
- **Staff user token** (regular offering tokens cannot submit historical data)
- Resources must already exist in Waldur
- SLURM accounting database must contain historical data for requested periods
### Periodic Limits Management
Periodic limits are managed automatically via event processing when enabled. The system:
1. **Receives signals** from Waldur Mastermind with calculated periodic settings
2. **Applies settings** to SLURM cluster (fairshare, limits, QoS)
3. **Monitors thresholds** and adjusts QoS based on current usage
4. **Reports status** back to Waldur
### Account Diagnostics
The `waldur_site_diagnose_slurm_account` command provides diagnostic information for SLURM
accounts by comparing local cluster state with Waldur Mastermind configuration.
```bash
# Basic diagnostic
waldur_site_diagnose_slurm_account alloc_myproject -c config.yaml
# JSON output for scripting
waldur_site_diagnose_slurm_account alloc_myproject --json
# Verbose output with reasoning
waldur_site_diagnose_slurm_account alloc_myproject -v
```
#### Diagnostic Data Flow

# Install development dependencies
uv add --dev slurm-emulator
# Install plugin in development mode
uv sync --all-packages
# Run tests
uv run pytest plugins/slurm/tests/ -v
```
### Adding New Features

## Troubleshooting
### Common Issues
#### SLURM Commands Not Found
```text
❌ Command 'sacctmgr' not found
```
**Solution**: Install SLURM client tools or use emulator mode for development.
#### Permission Denied
```text
❌ Permission denied executing sacctmgr
```
**Solution**: Ensure site agent runs with appropriate SLURM privileges or configure sudo access.
#### Periodic Limits Not Working
```text
❌ Periodic limits updates not received
```
**Solutions**:
- Verify event processing is enabled
- Check STOMP connection settings
- Ensure offering has `periodic_limits.enabled: true`
- Verify STOMP broker is publishing periodic limits events
#### Historical Loading Errors
```text
❌ Historical usage loading requires staff user privileges
```
**Solution**: Use an API token from a user with `is_staff=True` in Waldur.
### Debug Commands
```bash
# Test SLURM connectivity
sacctmgr list account format=account,description
# Test site agent backend
python -c "
from waldur_site_agent_slurm.backend import SlurmBackend
backend = SlurmBackend({}, {})
print(backend.ping())
"
# Test periodic limits
python -c "
from waldur_site_agent_slurm.backend import SlurmBackend
backend = SlurmBackend({'periodic_limits': {'enabled': True}}, {})
result = backend.apply_periodic_settings('test_account', {'fairshare': 100})

### SLURM Emulator Usage in Tests
# SLURM Emulator Usage in Tests
## How the Emulator is Used
### 🎯 **Integration Method: PyPI Package**
The SLURM emulator is available as a pip package:
```python
# Clean package imports
try:
import emulator
EMULATOR_AVAILABLE = True
except ImportError:
EMULATOR_AVAILABLE = False
# Import emulator components directly
from emulator.core.database import SlurmDatabase
from emulator.scenarios.sequence_scenario import SequenceScenario
from emulator.periodic_limits.calculator import PeriodicLimitsCalculator
```text
### 📦 **Package Features:**
- ✅ **Clean imports**: No `sys.path` manipulation needed
- ✅ **Test dependency**: Optional dependency in SLURM plugin
- ✅ **CI/CD friendly**: Standard uv installation
## Three Ways to Use the Emulator
### 1. **Running API Server** (Current Production Method) ✅
```bash
# Start emulator API server
uvicorn emulator.api.emulator_server:app --host 0.0.0.0 --port 8080
```text
**Used by**:
- Site agent backend in emulator mode
- Integration tests that need HTTP API
- Real-time scenario execution
**API Endpoints**:
- `GET /api/status` - Emulator state
- `POST /api/apply-periodic-settings` - Apply settings
- `POST /api/time/advance` - Time manipulation
- `POST /api/usage/inject` - Usage injection
### 2. **Direct Python Import** (New Testing Method) ✅
```python
# Import emulator components directly
from emulator.scenarios.sequence_scenario import SequenceScenario
from emulator.periodic_limits.calculator import PeriodicLimitsCalculator
# Use emulator's calculation engine
calculator = PeriodicLimitsCalculator(database, time_engine)
settings = calculator.calculate_periodic_settings(account)
```text
**Used by**:
- Unit tests that need exact emulator calculations
- Scenario validation tests
- Performance benchmarking
**Benefits**:
- No network overhead
- Direct access to calculation engines
- Can inspect internal state
### 3. **CLI Command Interface** (Available but Limited) ⚠️
```bash
# Interactive CLI
python -m emulator.cli.main
# Or programmatic CLI
echo "account create test-account 'Test' 1000" | python -m emulator.cli.main
```text
**Used by**:
- Manual testing and exploration
- Some integration tests via subprocess
**Limitations**:
- More complex to automate
- Harder to extract results programmatically
## Test Integration Architecture
### **Current Test Structure** ✅
```text

### Waldur Federation Plugin for Waldur Site Agent
# Waldur Federation Plugin for Waldur Site Agent
Waldur-to-Waldur federation backend plugin for Waldur Site Agent. Enables federating
resources, usage, and memberships between two Waldur instances (Waldur A and Waldur B),
replacing the `marketplace_remote` Django app with a stateless, polling-based approach.
## Overview
The plugin acts as a bridge: Waldur A (the "local" instance) receives orders from users
and delegates resource lifecycle management to Waldur B (the "target" instance) via its
marketplace API. Usage is pulled back from Waldur B and reported to Waldur A, with
optional component type conversion.
```mermaid
graph LR
subgraph "Waldur A (Local)"
USER[User]
ORDER_A[Marketplace Order]
RESOURCE_A[Resource on A]
end
subgraph "Site Agent"
BACKEND[WaldurBackend]
MAPPER[ComponentMapper]
CLIENT[WaldurClient]
end
subgraph "Waldur B (Target)"
ORDER_B[Marketplace Order]
RESOURCE_B[Resource on B]
USAGE_B[Usage Data]
end
USER --> ORDER_A
ORDER_A --> BACKEND
BACKEND --> MAPPER
MAPPER --> CLIENT
CLIENT --> ORDER_B
ORDER_B --> RESOURCE_B
USAGE_B --> CLIENT
CLIENT --> MAPPER
MAPPER --> BACKEND
BACKEND --> RESOURCE_A

classDef waldurB fill:#fff3e0
class USER,ORDER_A,RESOURCE_A waldurA
class BACKEND,MAPPER,CLIENT agent
class ORDER_B,RESOURCE_B,USAGE_B waldurB
```
## Features
- **Order Forwarding**: Create, update, and terminate resources on Waldur B via marketplace orders
- **Non-blocking Order Creation**: Returns immediately after submitting order on B;
tracks completion via `check_pending_order()` on subsequent polling cycles
- **Target STOMP Subscriptions**: Optional instant order-completion notifications
from Waldur B via STOMP, eliminating polling delay
- **Component Mapping**: Configurable conversion factors between Waldur A and Waldur B component types
- **Passthrough Mode**: 1:1 forwarding when no conversion is needed
- **Usage Pulling**: Fetches total and per-user usage from Waldur B, reverse-converts to Waldur A components
- **Membership Sync**: Synchronizes project memberships with configurable user matching (CUID, email, username)
- **Role Mapping**: Configurable role name translation between Waldur A and B (e.g., `PROJECT.ADMIN` → `PROJECT.MANAGER`)
- **Project Tracking**: Automatic project creation on Waldur B with `backend_id` mapping
## Architecture
### Component Overview
```mermaid
graph TB
subgraph "WaldurBackend"
INIT[Initialization:`. |
### User Attributes Synced
The backend pushes all exposed offering user attributes to identity bridge, including:
first name, last name, email, organization, affiliations, phone number, gender,
birth date, nationality, and other profile fields configured via `OfferingUserAttributeConfig`.
## Project Mapping
Projects on Waldur B are tracked using `backend_id`:
```text
backend_id = "{customer_uuid_on_A}_{project_uuid_on_A}"
```
On each resource creation, the plugin:
1. Searches for an existing project on Waldur B with the matching `backend_id`
2. Creates a new project under the configured `target_customer_uuid` if not found
3. Uses the project for all subsequent operations on that resource

### Waldur Federation E2E Test Plan
# Waldur Federation E2E Test Plan
## Overview
End-to-end tests for Waldur-to-Waldur federation via the site agent.
The agent sits between two Waldur instances and forwards orders, usage,
and memberships.
```text
Waldur A (source) Site Agent Waldur B (target)
Marketplace.Slurm offering <--> OfferingOrderProcessor <--> Marketplace.Slurm offering
WaldurBackend
```
The tests exercise both operational modes:
- **REST polling mode** (`order_process`): Agent polls for orders on A,
creates resources on B, checks order completion on B via
`check_pending_order()` on subsequent processor cycles.
- **STOMP event mode** (`event_process`): Agent receives ORDER events
from both Waldur A (source) and Waldur B (target) via STOMP over
WebSocket. Target STOMP provides instant order completion notification.
## Environment
| Variable | Value | Description |
|---|---|---|
| `WALDUR_E2E_TESTS` | `true` | Gate: skip all E2E tests if not set |
| `WALDUR_E2E_CONFIG` | `` | Agent config file |
| `WALDUR_E2E_PROJECT_A_UUID` | `` | Project UUID on Waldur A |
### Instance Requirements
| Instance | Requirements |
|---|---|
| Waldur A (source) | Active `Marketplace.Slurm` offering with plan; see Step 2 for token permissions |
| Waldur B (target) | Active `Marketplace.Slurm` offering with matching components; see Step 1 for token permissions |
### Setup Instructions
Follow these steps to prepare two Waldur instances for E2E testing.
All operations can be done via Waldur Admin UI or REST API.
#### Step 1: Waldur B (Target) — Organization and Offering
Create the target side first, because you'll need its UUIDs for the
agent config.
1. **Create or choose an organization** on Waldur B.
Note its UUID — this becomes `target_customer_uuid`.
2. **Create a `Marketplace.Slurm` offering** under that organization:
- Offering type: `Marketplace.Slurm` (required for STOMP event signals
and agent identity registration)
- Add components that match your source offering. For each component:
- **Type**: `limit` (billing type)
- **Billing type**: `limit`
- **Measured unit**: any (e.g., "Units", "Hours")
- Note the offering UUID — this becomes `target_offering_uuid`.
3. **Add a plan** to the offering:
- Any name (e.g., "Default")
- Set prices for each component (can be 0 for testing)
4. **Activate the offering**:
- Set offering state to `Active` (via Admin UI or API)
5. **Create an API token** on Waldur B:
- The token user must be a **customer owner** (can be a non-SP
customer separate from the offering's service provider) and an
**ISD identity manager** (`is_identity_manager: true` with
`managed_isds` set)
- This becomes `target_api_token`
#### Step 2: Waldur A (Source) — Offering and Project
1. **Create a `Marketplace.Slurm` offering** on Waldur A:
- Offering type: `Marketplace.Slurm`
- Add components that map to B's components. For each component:
- **Type**: `limit` (billing type)
- **Billing type**: `limit`
- **Measured unit**: any (e.g., "Node-hours", "TB-hours")
- Note the offering UUID — this becomes `waldur_offering_uuid`.
2. **Add a plan** to the offering:
- Any name (e.g., "Default")
- Set prices for each component (can be 0 for testing)
3. **Activate the offering**:
- Set offering state to `Active`
4. **Create a project** on Waldur A:
- The project must belong to an organization that has access to the
offering (via category or direct assignment)
- Note the project UUID — this becomes `WALDUR_E2E_PROJECT_A_UUID`
5. **Create an API token** on Waldur A:
- The token user must have **OFFERING.MANAGER** role on the offering
- This becomes `waldur_api_token`
#### Step 3: Component Mapping
The agent config maps source components (A) to target components (B).
Two modes are available:
**Passthrough mode** (1:1, same component names):
```yaml
backend_components:
cpu:
measured_unit: "Hours"
unit_factor: 1.0
accounting_type: "limit"
label: "CPU"
# No target_components → forwarded as-is to B
```
Both offerings must have a component with the internal name `cpu`.
**Conversion mode** (N:M with factors):
```yaml
backend_components:
node_hours: # Component name on A
measured_unit: "Node-hours"
unit_factor: 1.0
accounting_type: "limit"
label: "Node Hours"
target_components:
cpu_k_hours: # Component name on B
factor: 128.0 # target_value = source_value * 128
```
A's `node_hours` component maps to B's `cpu_k_hours` with a 128x
multiplier. One source component can map to multiple target components.
**Important:** Component internal names (the YAML keys) must match the
component types defined on each respective offering. Check component
types via API:
```text
GET /api/marketplace-provider-offerings// → components[].type
```
#### Step 4: Optional — STOMP Event Processing
For STOMP tests (Tests 5-8), additional setup is required.
**On Waldur A:**
- Verify `/rmqws-stomp` WebSocket endpoint is available:
```bash
curl -sI https:///rmqws-stomp
# Expected: HTTP 426 (Upgrade Required)
```
- Set `stomp_enabled: true` and `websocket_use_tls: true` in config
**On Waldur B (target STOMP):**
- Verify `/rmqws-stomp` WebSocket endpoint is available (same curl test)
- The target offering must be `Marketplace.Slurm` for STOMP to work
(`Marketplace.Basic` does not support STOMP event signals)
- Set `target_stomp_enabled: true` in backend settings
If Waldur B does not have `/rmqws-stomp` configured (returns HTTP 200
instead of 426), skip target STOMP tests. The agent will fall back to
polling via `check_pending_order()`.
#### Step 5: User Matching
The agent maps users between Waldur A and B using a configurable field.
Set `user_match_field` in backend settings:
| Value | Matches on | When to use |
|---|---|---|
| `cuid` | Community User ID | Both instances use same IdP (e.g., eduTEAMS) |
| `email` | Email address | Users have same email on both instances |
| `username` | Username | Users have same username on both |
For E2E tests that only exercise order processing (Tests 1-4), user
matching is not critical. For membership sync tests, users must exist
on both instances with matching field values.
### Configuration Template
```yaml

```
## Test Scenarios: REST Polling Mode
### Test 1: Processor Initialization (`test_processor_init`)
**Purpose:** Verify `OfferingOrderProcessor` connects to Waldur A with
`WaldurBackend` pointing at Waldur B.
**Steps:**
1. Load config from YAML
2. Create `OfferingOrderProcessor(offering, waldur_client_a, backend)`
3. Verify `processor.resource_backend` is the backend instance
**Expected:** Processor initializes without errors.
### Test 2: Create Order (`test_create_order`)
**Purpose:** Full non-blocking create lifecycle:
order on A -> processor creates resource on B -> order completes.
**Steps:**
1. Fetch offering URL and plan URL from
`marketplace-public-offerings/{uuid}/` on A
2. Fetch project URL from `projects/{uuid}/` on A
3. Build limits from configured components (small test values)
4. Create order on A via `marketplace_orders_create`
5. Run `_run_processor_until_order_terminal()` (max 15 cycles, 3s delay):
- Cycle 1: Processor picks up order, calls
`WaldurBackend.create_resource_with_id()` (non-blocking)
- Backend submits order on B, returns `pending_order_id`
- Processor sets source order `backend_id` = target order UUID
- Cycle 2+: Processor calls `check_pending_order(backend_id)`
- `AutoApproveWaldurBackend` auto-approves `PENDING_PROVIDER` on B
- Eventually returns `True` -> processor marks order DONE
6. Verify resource on A has `backend_id` set (= B's resource UUID)
7. Verify resource exists on B using A's `backend_id` as UUID
**Expected:**
- Order reaches terminal state (DONE or ERRED)
- Resource on A has non-empty `backend_id`
- Resource exists on B at UUID = A's `backend_id`
- Component limits converted correctly (source * factor = target)
**Key design rule:** Agent does NOT set `backend_id` on target resource (B).
Only A's resource gets `backend_id` = B's resource UUID.
### Test 3: Update Limits (`test_update_limits`)
**Purpose:** Update limits on an existing resource.
**Depends on:** Test 2 (needs `resource_uuid_a`)
**Steps:**
1. Create update order on A via
`POST /api/marketplace-resources/{uuid}/update_limits/`
2. Run `_run_processor_until_order_terminal()`
- Processor calls `WaldurBackend.set_resource_limits(backend_id, limits)`
- Backend converts limits and creates update order on B
- `AutoApproveWaldurClient.poll_order_completion()` auto-approves on B
3. Verify order reaches terminal state
**Expected:**
- Resource limits updated on B (with conversion factor applied)
**Known issue:** Waldur may create a "shadow" resource for Update orders
with empty `backend_id`. See Known Issues section.
### Test 4: Terminate Resource (`test_terminate_resource`)
**Purpose:** Terminate resource through the processor.
**Depends on:** Test 2 (needs `resource_uuid_a`, `resource_uuid_b`)
**Steps:**
1. Create terminate order on A via
`POST /api/marketplace-resources/{uuid}/terminate/`
2. Run `_run_processor_until_order_terminal()`
- Processor calls `WaldurBackend.delete_resource(waldur_resource)`
- Backend creates terminate order on B
- Polls B for order completion
3. Verify resource on A state != `OK`
4. Verify resource on B state != `OK`
**Expected:**
- Both resources end up in non-OK state (typically `TERMINATED`)
## Test Scenarios: STOMP Event Mode
These tests require `stomp_enabled: true` in the config and
a Waldur instance with STOMP-over-WebSocket (`/rmqws-stomp`) configured.
### Test 5: Source STOMP Connection (Waldur A) — Automated
**Purpose:** Verify STOMP connections to Waldur A establish correctly.
**Pre-flight:** `check_stomp_available()` sends HTTP GET to
`/rmqws-stomp` — expects HTTP 426. Skips test if unavailable.
**Steps:**
1. `setup_stomp_offering_subscriptions()` registers agent identity,
creates event subscriptions, and establishes STOMP connections
2. Test verifies each source consumer `conn.is_connected()`
3. Report captures connection details per subscription type
**Expected:**
- 5 source STOMP connections established (ORDER, USER_ROLE, RESOURCE,
SERVICE_ACCOUNT, COURSE_ACCOUNT)
- All connections report `is_connected() == True`
**Prerequisites:** Waldur A must have `/rmqws-stomp` WebSocket endpoint
configured in nginx, proxying to RabbitMQ's `rabbitmq_web_stomp` plugin.
**Verification:**
```bash
# Should return HTTP 426 (Upgrade Required) — correct for WebSocket
curl -sI https:///rmqws-stomp
```
### Test 6: Target STOMP Connection (Waldur B) — Automated
**Purpose:** Verify STOMP connection to Waldur B for instant order
completion notifications.
**Config required:**
```yaml
backend_settings:
target_stomp_enabled: true
```
**Steps:**
1. `setup_stomp_offering_subscriptions()` also sets up target STOMP
when `target_stomp_enabled=true`. Target consumers have offering
name prefixed with `"Target: "`.
2. Test verifies each target consumer `conn.is_connected()`
3. If no target consumers exist, test is skipped (graceful)
**Expected:**
- 2 target STOMP connections established (ORDER and OFFERING_USER events on B)
- All connections report `is_connected() == True`
- Skipped gracefully if `target_stomp_enabled=false`
**Prerequisites:** Waldur B must have `/rmqws-stomp` WebSocket endpoint
configured. Verify with:
```bash
# Should return HTTP 426 (Upgrade Required)
curl -sI https:///rmqws-stomp
# If HTTP 200 with text/html — STOMP is NOT configured on this server
```
### Test 7: STOMP Order Event Flow (Automated)
**Purpose:** Verify STOMP events are received while orders are
processed via the standard REST-based processor. This is a hybrid
approach: STOMP connections are established and events are captured
in a thread-safe `MessageCapture`, while order processing uses the
same REST `_run_processor_until_order_terminal()` as Tests 1-4.
**Depends on:** Tests 5+6 (STOMP connections established)
**Steps:**
1. Create a CREATE order on Waldur A via REST API
2. Wait for source STOMP event (order notification from A, 30s timeout)
3. Process order via REST-based `_run_processor_until_order_terminal()`
(same mechanism as Test 2)
4. Fetch resource info and verify `backend_id` on A
5. If target STOMP is active, wait for target STOMP event (30s timeout)
6. Snapshot resource state on A
**Expected:**
- Source STOMP event received with matching `order_uuid` and
`order_state=pending-consumer`
- Order reaches terminal state (DONE) via REST processing
- Resource on A has `backend_id` set
- If target STOMP active: target event may be captured (timing-dependent)
**Cleanup (Test 7b):**
The test class includes a cleanup test that terminates the resource
created in Test 7, using the same REST processor mechanism.
### Test 8: Fallback When Target STOMP Unavailable
**Purpose:** Verify federation works in polling mode when Waldur B
does not have STOMP-over-WebSocket configured.
**Config:**
```yaml
backend_settings:
target_stomp_enabled: false # or omit entirely
```
**Steps:**
1. Start agent in `order_process` mode (polling)
2. Create order on A
3. Processor creates resource on B (non-blocking)
4. Processor polls `check_pending_order()` on subsequent cycles
5. Auto-approve on B (in tests) or wait for B's backend processor
6. `check_pending_order()` returns `True` when target order DONE
**Expected:**
- Same end result as STOMP mode, but with polling delay
(max: `order_poll_timeout` seconds)
- This is the same flow as Tests 1-4 above
## Known Issues
### 1. `set_state_done` Returns HTTP 500
The `set_state_done` API endpoint on some Waldur staging instances
intermittently returns HTTP 500. The flow:
1. Backend operation succeeds (resource created/updated/terminated on B)
2. `_process_create_order()` returns `True`
3. Processor calls `marketplace_orders_set_state_done.sync_detailed()`
4. Server returns HTTP 500 -> `UnexpectedStatus` exception
5. Generic exception handler at `processors.py:573` catches it
6. Handler calls `set_state_erred` -> order marked ERRED despite success
**Impact:** Tests must tolerate ERRED state and verify actual
resource state.
**Mitigation:** `_run_processor_until_order_terminal()` returns the
final `OrderState` without failing. Tests verify resource state
regardless of order state.
### 2. Shadow Resource on Update/Terminate Orders
Waldur creates a "shadow" resource entry for Update and Terminate
orders. The order's `marketplace_resource_uuid` points to the shadow:
- Empty `backend_id`
- Empty `name`
The original resource retains its `backend_id` and is in `OK` state.
**Impact:**
- Update: `ValueError: badly formed hexadecimal UUID string`
when calling `UUID("")`
- Terminate: `Empty backend_id for resource, skipping deletion`
**Planned fix:** `_resolve_resource_backend_id()` helper in
`processors.py` that falls back to listing resources in the same
offering+project when `backend_id` is empty.
### 3. Target STOMP WebSocket Not Configured
Some Waldur instances do not have the `/rmqws-stomp` WebSocket proxy
configured in nginx.
**Verification:**
```bash
# WebSocket endpoint available (correct):
curl -sI https:///rmqws-stomp
# HTTP/2 426 (Upgrade Required)
# WebSocket not configured (serves frontend instead):
curl -sI https:///rmqws-stomp
# HTTP/2 200 text/html
```
**Impact:** Target STOMP subscriptions cannot connect. Agent falls
back to polling via `check_pending_order()`.
**Fix:** Configure nginx to proxy `/rmqws-stomp` to RabbitMQ's
`rabbitmq_web_stomp` plugin (typically port 15674).
### 4. Source STOMP Reconnections
STOMP connections may disconnect and reconnect periodically. Likely
caused by heartbeat timeout mismatch between client (10s) and server.
**Impact:** Functional but generates log noise. May miss events during
reconnection window.
## Test Infrastructure
### MessageCapture (conftest.py)
Thread-safe STOMP message capture for automated tests. Wraps or
replaces STOMP `on_message_callback` handlers on `WaldurListener`.
- Source handlers: replaced with capture-only (no order processing)
- Target handlers: wrapped with capture + delegate to original handler
```python
class MessageCapture:
def make_handler(self, delegate=None):
# Returns STOMP handler: (frame, offering, user_agent) -> None
# Captures message, signals waiters, optionally delegates
def wait_for_order_event(self, order_uuid, timeout=60):
# Blocks until ORDER event with matching UUID, or timeout
```
### AutoApproveWaldurBackend (conftest.py)
Extends `WaldurBackend`. Overrides `check_pending_order()` to
auto-approve `PENDING_PROVIDER` orders on B. Required because there
is no real backend processor (e.g., SLURM site agent) running on B
in tests.
```python
class AutoApproveWaldurBackend(WaldurBackend):
def check_pending_order(self, order_backend_id: str) -> bool:
# PENDING_PROVIDER -> approve via API, return False
# DONE -> return True
# ERRED/CANCELED/REJECTED -> raise BackendError
```
### AutoApproveWaldurClient (integration_helpers.py)
Extends `WaldurClient`. Overrides `poll_order_completion()` to
auto-approve `PENDING_PROVIDER` orders. Used by the backend for
synchronous operations (update limits, terminate).
### _run_processor_until_order_terminal (test_e2e_federation.py)
Runs `process_offering()` in a loop (max 15 cycles, 3s between).
Returns the final `OrderState` without failing on ERRED.
## Test Scenarios: Membership Sync
### Test 9: Membership Sync — Add/Remove User (`test_e2e_membership_sync.py`)
**Purpose:** Verify `WaldurBackend.add_user()` and `remove_user()` work
end-to-end with identity bridge resolution and role mapping.
**Prerequisites:**
- An OK resource on Waldur A with `backend_id` pointing to Waldur B
(created by Test 2 or an existing allocation)
- A user with an offering_user on Waldur A whose identity resolves on
Waldur B (via CUID / identity bridge)
**Steps:**
1. Find an OK resource on Waldur A linked to Waldur B
2. Find a shared user (offering_user on A resolvable on B via identity bridge)
3. Call `backend.add_user(resource, username, role_name="PROJECT.MANAGER")`
- Backend resolves user via identity bridge
- Role mapped via `role_mapping` config (if present)
- User added to project on Waldur B via `add_user_to_project()`
4. Verify user has role in the project on Waldur B
5. Call `backend.remove_user(resource, username, role_name="PROJECT.MANAGER")`
6. Verify user role was removed on Waldur B
**Expected:**
- `add_user` returns `True`, user appears in project on B
- `remove_user` returns `True`, user role is removed on B
- Role mapping applied correctly (e.g., `PROJECT.MANAGER` → `PROJECT.MANAGER`)
**Configuration:**
```yaml
backend_settings:
role_mapping:
PROJECT.ADMIN: PROJECT.ADMIN
PROJECT.MANAGER: PROJECT.MANAGER
PROJECT.MEMBER: PROJECT.MEMBER
```

### test_06 — Skips Non-qualifying Offering
Verifies reconciliation skips offerings without `stomp_enabled` or `membership_sync_backend`.
### test_07 — Cleanup
Deletes offering users and entities.
## Key Design Decisions
### Natural Offering User Auto-Creation (Suite 1)
The `env` fixture uses Waldur's natural flow for creating offering users:
1. **Resource creation via Django ORM** — `Marketplace.Slurm` offerings can't create
orders via API without a real SLURM backend (no `scope`/service_settings). Resources
are created directly with `state=Resource.States.OK`.
2. **Project role assignment via API** — `POST /api/projects/{uuid}/add_user/` fires
the `role_granted` signal.
3. **Task invocation via Django shell** — Since there's no Celery worker with `runserver`,
the `create_or_restore_offering_users_for_user` task is called directly via
`uv run waldur shell -c "..."`.
This produces offering users in `CREATION_REQUESTED` state with empty username
(`username_generation_policy=service_provider`), matching production behavior.
### STOMP Message Summary (Suite 2)
| # | Action | Received by |
|---|--------|-------------|
| 1-5 | create, update, username_set | user_a + user_b |
| 6-7 | update, username_set (after clearing ISDs) | user_a only |
**Key finding:** After clearing `managed_isds` on user_b, event publishing correctly
filters based on ISD identity manager access.

### SLURM provider
# SLURM provider
SLURM plugin enables sharing of access to a [SLURM](https://slurm.schedmd.com/) cluster.
SLURM is a scheduling system used typically for managing High-performance clusters. Waldur allows to
share access by creating Slurm accounts and managing permission rights of users.
## Important note
This page describes the legacy marketplace plugin for SLURM.
For the new SLURM plugin, we recommend to check [this page](site-agent/index.md)
## Configure Waldur SLURM plugin
By default, Waldur creates a hierarchical account structure in SLURM, where:
- Organization gets an account under a default account, defined when configuring SLURM service offering;
- Each project is created as a an allocation, which is a child of organization's account.
- Each resource created in Waldur (aka SLURM Allocation) gets its own SLURM account with project account as a parent.
These accounts get standard prefixes along with unique values and user provided input.
It is possible to customize prefixes in Waldur configuration. Check WALDUR_SLURM variables in
[Waldur configuration guide](../mastermind-configuration/configuration-guide.md).
## Add SLURM provider
To add SLURM as a [provider](../../user-guide/service-provider-organization/adding-an-offering.md) to Waldur, you will need the following information:
- SSH host address to a node, from where SLURM commands could be executed.
- Username that has Slurm [operator role](https://slurm.schedmd.com/user_permissions.html).
Operator is needed as Waldur dynamically creates accounts based on user's choice of FreeIPA account.
- Waldur public key must be added as authorized_key for the operator's username.
- Slurm login node must be configured to authenticate users coming from FreeIPA connected to Waldur.
## SLURM auto-provisioning hooks
It is possible to streamline creation of SLURM allocations for new users based on affiliation of a user profile.
Configuration settings are described in [Waldur configuration guide](../mastermind-configuration/configuration-guide.md)
under WALDUR_HPC settings.
The logic is as follows:
- Once a user is created (e.g. via eduGAIN login), user's affiliation and email are checked to see if user belongs
to internal or external organization.
- If so, a project is created for the user in a corresponding organization.
- For users belonging to internal organization, SLURM request is pre-filled and created using account limits of
internal organizations.
- For users belonging to external organization, SLURM request is pre-filled only - it would require a manual confirmation
from the organization owner of the external organization to be provisioned. Default limits of SLURM apply.
## Configure SLURM cluster
Waldur might work out of the box with most of the reasonably modern deployments of SLURM, which have
accounting enabled and limits enforced.
Please refer to SLURM documentation for details:
- [SLURM Accounting](https://slurm.schedmd.com/accounting.html)
- [SLURM Resource Limits](https://slurm.schedmd.com/resource_limits.html)
- [SLURM Multifactor Priority Plugin](https://slurm.schedmd.com/priority_multifactor.html)
We provide a snapshot of instructions for the convenience of the reader.
### Add SLURM cluster
SLURM accounting plugin assumes that at least one cluster is configured. For example:
```bash
sacctmgr add cluster linux
```
### Enforce SLURM accounting limits
In order to enforce limits set on associations and QoS, please modify slurm.conf:
```bash
AccountingStorageEnforce=limits
```
Please note, that when AccountingStorageEnforce is changed, a restart of the slurmctld daemon is required (not just a ``scontrol reconfig``):
```bash
systemctl restart slurmctld
```
### Enable SLURM Multi Priority plugin
In order to enable ordering for the queue of jobs waiting to be scheduled, please modify slurm.conf:
```bash
PriorityType=priority/multifactor
```
When slurm.conf is changed, you should reload configuration:
```bash
scontrol reconfig
```

## API Authentication
### Authentication
# Authentication
Outline:
- [Authentication](#authentication)
- [Authentication with username and password](#authentication-with-username-and-password)
- [Authentication Token management](#authentication-token-management)
Waldur MasterMind exposes REST API for all of its operations. Below are examples of typical operations performed against APIs. To run the examples, we are using a [HTTPie](https://httpie.org/).
Almost all of the operations with API require an authentication token. Below we list two methods on how to get it.
## Authentication with username and password
If your account is allowed to use username/password and the method is enabled (e.g. in dev environment), you can get a new token by submitting a username/password as JSON to a specific endpoint.
```bash
$ http -v POST https://waldur.example.com/api-auth/password/ username=user password=password
POST /api-auth/password/ HTTP/1.1
Accept: application/json, */*;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Content-Length: 40
Content-Type: application/json
Host: waldur.example.com
User-Agent: HTTPie/2.3.0
{
"password": "user",
"username": "password"
}
HTTP/1.1 200 OK
Access-Control-Allow-Credentials: true
Access-Control-Allow-Headers: Accept, Accept-Encoding, Authorization, Content-Type, Origin, User-Agent, X-CSRFToken, X-Requested-With

}
```
## Authentication Token management
The easiest way to obtain your token is via Waldur HomePort.
Open your user dashboard by clicking on your name in the upper left corner, then select **Credentials** -> **API token**.
[Image: Credentials]
A page with your API token will open. Click on the eye icon to reveal the token.

## API Permissions
### Permissions
# Permissions
## Listing permissions
Entities of Waldur are grouped into *organisational units*. The
following *organisational units* are supported: customer and project.
Each *organisational unit* has a list of users associated with it.
Getting a list of users connected to a certain *organisational unit* is
done through running a GET request against a corresponding endpoint.
- customer: endpoint `/api/customer-permissions/`
- project: endpoint `/api/project-permissions/`
Filtering by *organisational unit* UUID or URL is supported. Depending
on the type, filter field is one of:
- `?customer=`
- `?customer_url=`
- `?project=`
- `?project_url=`
- `?user_url=`
In addition, filtering by field names is supported. In all cases
filtering is based on case insensitive partial matching.
- `?username=`
- `?full_name=`
- `?native_name=`
Ordering can be done by setting an ordering field with
`?o=`. For descending ordering prefix field name with a
dash (-). Supported field names are:
- `?o=user__username`
- `?o=user__full_name`
- `?o=user__native_name`
## Fetch user data from Waldur using username
To fetch user data together with its permissions, you need to perform the following HTTP request.
It requires `username` filter and valid API token.
```http
GET /api/users/?username=&field=uuid&field=customer_permissions&field=project_permissions
Accept: application/json
Authorization: Token
Host: example.com
```
Example:
```bash
> http -v --pretty all GET http://example.com:8000/api/users/ username==admin field==uuid field==customer_permissions field==project_permissions Authorization:"Token 154f2c6984b5992928b62f87950ac529f1f906ca"

## API Overview
### REST API
# REST API
## Authentication
Waldur uses token-based authentication for REST.
In order to authenticate your requests first obtain token from any of
the supported token backends. Then use the token in all the subsequent
requests putting it into `Authorization` header:
``` http
GET /api/projects/ HTTP/1.1
Accept: application/json
Authorization: Token c84d653b9ec92c6cbac41c706593e66f567a7fa4
Host: example.com
```
Also token can be put as request GET parameter, with key `x-auth-token`:
``` http
GET /api/?x-auth-token=Token%20144325be6f45e1cb1a4e2016c4673edaa44fe986 HTTP/1.1
Accept: application/json
Host: example.com
```
## API version
In order to retrieve current version of the Waldur authenticated user
should send a GET request to **/api/version/**.
Valid request example (token is user specific):
``` http
GET /api/version/ HTTP/1.1
Content-Type: application/json
Accept: application/json
Authorization: Token c84d653b9ec92c6cbac41c706593e66f567a7fa4
Host: example.com
```
Valid response example:
``` http
HTTP/1.0 200 OK
Content-Type: application/json
Vary: Accept
Allow: OPTIONS, GET
{
"version": "0.3.0"
}
```
## Pagination
Every Waldur REST request supports pagination. Links to the next,
previous, first and last pages are included in the Link header.
*X-Result-Count* contains a count of all entries in the response set.
By default page size is set to 10. Page size can be modified by passing
**?page_size=N** query parameter. The maximum page size is 100.
Example of the header output for user listing:
``` http
HTTP/1.0 200 OK
Vary: Accept
Content-Type: application/json
Link:
; rel="first",
; rel="next",
; rel="prev",
; rel="last"
X-Result-Count: 54
Allow: GET, POST, HEAD, OPTIONS
```
## Common operations
If you are integrating a python-based application, you might find useful a [python wrapper](../sdk.md) for typical operations.
Almost all operations require authentication. Authentication process is a two-step:
1. Generation of authentication token using [Authentication API](authentication.md).
2. Passing that token in the Authorization header along with all other REST API calls.
Please note that all of the responses to the listing are paginated, by default up to 10 elements are returned.
You can request more by passing `page_size=` argument, number up to 200 will be respected. Information
about the whole set is contained in the response headers. Check [example of a "get_all" function](https://github.com/waldur/ansible-waldur-module/blob/6679b6b8f9ca21099eb3a6cb97e846d3e8dd1249/waldur_client.py#L140)
to see how a full traversal can be done.
## Project management
### Customer lookup
Waldur implements a multi-tenant model to allow different organizations to allocate shared resources simultaneously
and independently from each other. Each such organizaton is a customer of Waldur and is able to create its own
projects. Project allows us to create new allocations as well as connect users with the project.
Hence, to create a project, one needs first to have a reference to the customer. The reference is a stable one and
can be cached by a REST API client.
Examples:
- [API call for customer lookup](project-api-examples.md#lookup-allocator-customers-available-to-a-user)
### Project creation
In order to create a new project in an organization, user needs to provide the following fields:
- **`customer`** - URL of the project's organization
- **`name`** - project's name
- `description` - description of a project description
- `end_date` - optional date when the project and all allocations it contains will be scheduled for termination.
- `backend_id` - optional identifier, which is intended to be unique in the resource allocator's project list. Can be used for connecting Waldur projects with the client's project registry.
- `oecd_fos_2007_code` - optional OECD Field of Science code. A code is represented by a string with two numbers separated by dot for a corresponding field of science. For example `"1.1"` is code for Mathematics. More information can be found [here](https://joinup.ec.europa.eu/collection/eu-semantic-interoperability-catalogue/solution/field-science-and-technology-classification/about).
Please note that the project becomes active at the moment of creation!
Examples:
- [API call for project creation](project-api-examples.md#create-a-new-project)
- [Project creation in Waldur](https://github.com/waldur/waldur-mastermind/blob/54689ac472b1a07fa815a5ddebcf35ea888d3dcc/src/waldur_mastermind/marketplace_remote/utils.py#L122).
### Project update
It is possible to update an existing project using its URL link. Name, description and backend_id can be updated.
Examples:
- [API call for project update](project-api-examples.md#update-an-existing-project)
### Project lookup
User can list projects and filter them using the following query parameters:
- `name` - project's name (uses 'contains' logic for lookup)
- `name_exact` - project's exact name
- `description` - project's description (uses 'contains' logic for lookup)
- `backend_id` - project's exact backend ID
In case API user has access to more than one customer, extra filter by customer properties can be added:
- `customer` - exact filter by customer UUID
- `customer_name` - filter by partial match of the full name of a customer
- `abbreviation` - filter by partial match of the abbreviation of a customer
Examples:
- [API call for listing of projects](project-api-examples.md#list-projects))
## Project membership management
Creating a membership for a user means creating a permission link. While multiple roles of a user per project are allowed,
we recommed for clarity to have one active project role per user in a project.
The list of fields for creation are:
- `user` - a user's UUID, looked up from a previous step.
- `role` - a role of the user. Both role UUID and name are supported. By default the system roles 'PROJECT.MEMBER', 'PROJECT.ADMIN' and 'PROJECT.MANAGER' are supported. TODO: add reference to Puhuri terminology.
- `expiration_time` - an optional field, if provided, it should contain date or ISO 8601 datetime.
To remove the permission, REST API client needs to send a HTTP request using the same payload as for permission creation,
but to `delete_user` endpoint .
It is also possible to list available project permissions along with a `role` filter.
Examples:
- [API call for allocating members to a project](project-api-examples.md#project-members-permissions-allocation)
- [API call for removing members from a project](project-api-examples.md#removal-of-members-from-a-project)
- [API call to listing project permissions](project-api-examples.md#list-project-permissions)
## Resource allocation management
Creating and managing resource allocations in Waldur follows ordering logic.
All operations on resources, which lead to changes in allocations - e.g. creation, modification of allocated limits
or termination - are wrapped in an order.
### Listing offerings
To create a new Allocation, one must first choose a specific Offering from available. Offering corresponds to a specific
part of a shared resource that Resource Allocator can allocate. Offerings can be visible to multiple allocators, however in the first iteration we plan to limit allocators with
access to only their owned shares.
User can fetch offerings and filter them by the following fields:
- `name` - offering's name
- `name_exact` - offering's exact name
- `customer` - organization's URL
- `customer_uuid` - organization's UUID
Generally Offering has a stable UUID, which can be used in Waldur client configuration. Offering defines inputs
that are required to provision an instance of the offering, available accounting plans (at least one should be present)
as well as attributes that can or should be provided with each request.
Each Offering contains one or more plans, you will need to provide a reference (URL) to the plan when creating an
allocation.
API examples:
- [Getting a list of offerings available for allocation](project-api-examples.md#getting-a-list-of-offerings)
### Orders and resources
To create a new allocation, an order must be created with requested attributes: project
as well as details about the allocations.
Order might require additional approvals - in this case upon creation its status will be `pending-consumer` or `pending-provider`, which
can transition to `REJECTED` if order is rejected.
Otherwise it will be switched to `EXECUTING`, ending either in `DONE` if all is good or `ERRED`, if error happens during the processing.
Resource UUID is available as a `marketplace_resource_uuid` field of the creation order.
In addition, ``accepting_terms_of_service`` flag must be provided as a lightweight confirmation that allocator is
aware and agreeing with Terms of services of a specific Offering.
Example of the order payload sent with `POST` to ``https://puhuri-core-beta.neic.no/api/marketplace-orders/``:
```json
{
"project": "https://puhuri-core-beta.neic.no/api/projects/72fff2b5f09643bdb1fa30684427336b/",
"offering": "https://puhuri-core-beta.neic.no/api/marketplace-public-offerings/0980e9426d5247a0836ccfd64769d900/",
"attributes": {
"name": "test20",
},
"limits":{
"gb_k_hours": 30,

},
"plan": "https://puhuri-core-beta.neic.no/api/marketplace-public-plans/14b28e3a1cbe44b395bad48de9f934d8/",
"accepting_terms_of_service": true
}
```
### Change resource limits
Send ``POST`` request to ``https://puhuri-core-beta.neic.no/api/marketplace-resources//update_limits/`` providing
the new values of limits, for example:
```json
{
"limits": {
"gb_k_hours": 35,
"cpu_k_hours": 6,
"gpu_k_hours": 200
}
}
```
### Resource termination
Send ``POST`` request to ``https://puhuri-core-beta.neic.no/api/marketplace-resources//terminate/``.

## Reporting
### Getting usage data of a specific resource allocation
To get reported usage for resources, send ``GET`` request to ``https://puhuri-core-beta.neic.no/api/marketplace-component-usages/``. If you want to get usage data of a specific resource, please add a filter, e.g. ``https://puhuri-core-beta.neic.no/api/marketplace-component-usages/?resource_uuid=``. Note that responses are paginated.
Additional filters that can be used:
- `date_before` - date of the returned usage records should be before or equal to provided, format YYYY-MM-DD, e.g. 2021-03-01.
- `date_after` - date of the returned usage records should be later or equal to provided, format YYYY-MM-DD, e.g. 2021-03-01.
- `offering_uuid` - return usage records only for a specified offering.
- `type` - type of the usage record to return, e.g. 'cpu_k_hours'.
Response will contain a list of usage records with a separate record for each component per month, for example:

## API Versioning and Change Policy
### API Versioning and Change Policy
# API Versioning and Change Policy
## Versioning scheme
Waldur uses semantic versioning: **`MAJOR.MINOR.PATCH`** (e.g., `8.0.5`).
- **MAJOR** version increments indicate significant platform changes.
- **MINOR** version increments are not currently used for separate cadence — patches ship as `MAJOR.MINOR.PATCH`.
- **PATCH** releases ship frequently and may contain new features, improvements, bug fixes, and occasionally breaking changes.
- **Release candidates** use the format `MAJOR.MINOR.PATCH-rc.N` (e.g., `8.0.6-rc.1`) for pre-release testing.
Releases are coordinated across all Waldur components (MasterMind, HomePort, Helm charts, Docker Compose, SDKs) — they all share the same version tag.
## How API changes are communicated
### Changelog
Every release includes a changelog entry in the [Changelog](../about/CHANGELOG.md) with categorized sections: features, improvements, bug fixes.
### OpenAPI schema diffs
For each release, an OpenAPI schema diff is auto-generated and published under the API Changes section (see e.g. [8.0.3 diff](APIs/api-changes/waldur-openapi-schema-8.0.3-diff.md)). These diffs show:
- New endpoints added
- Endpoints removed
- Changed parameters, fields, or response structures
For example, `waldur-openapi-schema-8.0.3-diff.md` lists all endpoint additions and removals between 8.0.2 and 8.0.3.
### SDK regeneration
The Python, Go, and TypeScript SDKs are regenerated from the OpenAPI schema on each release. SDK users can pin to a specific version and review the updated schema before upgrading.
## Deprecation
Deprecated endpoints are marked with the `deprecated` flag in the OpenAPI schema. When an endpoint is deprecated:
1. The `deprecated: true` flag is set in the OpenAPI spec.
2. The endpoint description is updated with a migration note (e.g., "DEPRECATED: please use the dedicated `/api/openstack-network-rbac-policies/` endpoint").
3. The change appears in the OpenAPI schema diff for that release.
!!! warning
Waldur does not currently guarantee a fixed deprecation window. Deprecated endpoints may be removed in any subsequent release. Integrators should migrate promptly when a deprecation notice appears.
## Types of API changes
### Backward-compatible changes
These changes do not break existing clients:
- Adding new endpoints
- Adding optional query parameters
- Adding new fields to responses
- Adding new enum values
### Breaking changes
These changes may require client updates:
- Removing or renaming endpoints
- Removing or renaming request/response fields
- Changing field types
- Making a previously optional field required
- Changing HTTP status codes
- Changing URL patterns
!!! tip
Review the OpenAPI schema diffs (under API Changes in the navigation) before upgrading to identify any breaking changes that affect your integration.
## Tracking changes as an integrator
1. **Before upgrading**: Review the [Changelog](../about/CHANGELOG.md) and the relevant API schema diff for your target version.
2. **Pin SDK versions**: Use version pinning in your dependencies so upgrades are deliberate.
3. **Watch for deprecation flags**: Periodically check the OpenAPI schema for newly deprecated endpoints.
4. **Test against RC releases**: Release candidates (`-rc.N`) are available for pre-release validation.
## Future improvements
We are working on improving API stability guarantees and change communication. See the [API Stability Roadmap](api-stability-roadmap.md) for planned improvements including formal deprecation windows, breaking change detection in CI, and upgrade impact tooling.

## Python SDK
### Waldur Python SDK
# Waldur Python SDK
Waldur SDK is a thin Python wrapper for common REST operations.
It allows you to interact with the Waldur REST API directly from your Python code.
The SDK is provided as a Python module named `waldur_api_client`.
## Installation
The Waldur SDK is available on PyPI and can be installed using either `pip` or `poetry`:
```bash
pip install waldur-api-client
uv add waldur-api-client
poetry add waldur-api-client
```
In order to perform operations, a user needs to create an instance of `AuthenticatedClient` class:
```python
from waldur_api_client import AuthenticatedClient
client = AuthenticatedClient(
base_url="https://api.example.com",
token="SuperSecretToken",
)
```
This instance provides interface for further interaction with Waldur and will be used across examples in related documentation.
## Error handling
If the API call fails or returns an unexpected status code, it may raise `UnexpectedStatus` exception if the client is configured with `raise_on_unexpected_status=True`. This can be handled using a `try...except` block. The exception contains both the status code and the response content for debugging purposes.
Example:
```python
from waldur_api_client.api.marketplace_resources import marketplace_resources_list
from waldur_api_client.errors import UnexpectedStatus
import pprint
try:
result = marketplace_resources_list.sync(client=client)
except UnexpectedStatus as e:
print(f"Status code: {e.status_code}")
print("Response content:")
pprint.pprint(e.content)
```
The `UnexpectedStatus` exception is raised when:
- The API returns a status code that is not documented in the OpenAPI specification
- The `raise_on_unexpected_status` client setting is enabled (default is disabled)
## Disabling TLS validation (not recommended!)
If you are running your commands against Waldur deployment with broken TLS certificates (e.g. in development),
the trick below can be used to disable validation of certificates by SDK, beware that **this is a security risk**.
```python
client = AuthenticatedClient(
base_url="https://internal_api.example.com",
token="SuperSecretToken",
verify_ssl=False,
)
```
Sometimes you may need to authenticate to a server (especially an internal server) using a custom certificate bundle.
```python
client = AuthenticatedClient(
base_url="https://internal_api.example.com",
token="SuperSecretToken",
verify_ssl="/path/to/certificate_bundle.pem",
)
```
## Air gapped installation
If your machine from where you run SDK is not connected to the public Internet, you can use the following method
to transfer required libraries.
On the machine with access to the Internet:
```shell
echo "https://github.com/waldur/py-client/archive/master.zip" > requirements.txt
mkdir dependencies
pip3 download -r requirements.txt -d dependencies/
```
Now transfer content of the dependencies folder and requirements.txt to a machine without public Internet and
run.
```shell
pip3 install --no-index --find-links dependencies/ -r requirements.txt
```

## API Examples

## Lookup allocator customers available to a user
In most cases integration user can see only one allocating organization, however it is
possible that the same account is used for allocating different shares, e.g. national share and community specific.
Projects are always created in the context of a specific customer, so as a first thing you need to lookup a specific
customer you want to use. Customer is a stable entity, so it's URL / UUID can be cached.

## Creation of a resource allocation
User can create an order providing requested allocation parameters.
- **`project`** - project's UUID
- **`offering`** - respectful offering's URL
- **`attributes`** - specific attributes for the offering
- **`plan`** - plan's URL (if offering is billable)
- **`limits`** - a set of resource limits for an allocation

If a token belongs to a staff user, the order can be approved automatically.
Otherwise, there is additional need for manual approval.
After that, order should be pulled until resource UUID is present (`marketplace_resource_uuid` field).

### Order approval and rejection
In order to approve order by consumer, you shall issue POST request against `/api/marketplace-orders/{UUID}/approve_by_consumer/` endpoint. Similarly in order to approve order by provider, you shall issue POST request against `/api/marketplace-orders/{UUID}/approve_by_provider/` endpoint. Otherwise, you shall issue POST request against `/api/marketplace-orders/{UUID}/reject_by_consumer/` or `/api/marketplace-orders/{UUID}/reject_by_provider/` endpoint.
Of course, these endpoints are available only if you have service provider or service consumer permission against corresponding offerings.

## Core Concepts
### Background processing
# Background processing
For executing heavier requests and performing background tasks Waldur is
using [Celery](https://docs.celeryproject.org/en/stable/). Celery is a task queue
that supports multiple backends for storing the tasks and results.
Currently Waldur is relying on RabbitMQ backend - RabbitMQ
server **must be** running for requests triggering background scheduling
to succeed.
## Finite state machines
Some of the models in Waldur have a state field representing their
current condition. The state field is implemented as a finite state
machine. Both user requests and background tasks can trigger state
transition. A REST client can observe changes to the model instance
through polling the `state` field of the object.
Let's take VM instance in 'offline' state. A user can request the
instance to start by issuing a corresponding request over REST. This
will schedule a task in Celery and transition instance status to
'starting_scheduled'. Further user requests for starting an instance
will get state transition validation error. Once the background worker
starts processing the queued task, it updates the Instance status to the
'starting'. On task successful completion, the state is transitioned
to 'online' by the background task.
## Error state of background tasks
If a background task has failed to achieve it's goal, it should transit
into an error state. To propagate more information to the user each
model with an FSM field should include a field for error message
information - **error_message**. The field should be exposed via REST.
Background task should update this field before transiting into an erred
state.
Cleaning of the error state of the model instance should clean up also
`error_message` field.

### Core Checklists
# Core Checklists
The core checklist module provides a flexible questionnaire system that enables organizations to manage various types of compliance and metadata requirements through customizable questionnaires with conditional logic and review workflows.

The checklist system is designed as an extendable staff-configured metadata schema
to be used in different scenarios, for example:
- **Project Metadata**: Extendable schema for project metadata
- **Project Compliance**: Ensures projects meet organizational standards
- **Proposal Compliance**: Validates proposals before submission
- **Offering Compliance**: Verifies marketplace offerings meet requirements
## Core Models
### Category
Groups checklists by category with icon support for UI display. Categories provide organizational structure for managing different types of compliance checklists.
### Checklist
Main container for compliance questions. Each checklist has a type (project/proposal/offering compliance/project metadata) and contains an ordered set of questions that users must complete.
**Key features:**
- Type-based categorization (project_compliance, proposal_compliance, offering_compliance, project_metadata)
- Dynamic question visibility based on user context and dependencies
- Optional category grouping for UI organization
- Timestamped for audit trail
### Question
Individual questions with configurable types, ordering, conditional user guidance, and review trigger logic based on answer values.
**Question Types:**
- **Boolean**: Yes/No/N/A responses
- **Single Select**: Choose one option from a list
- **Multi Select**: Choose multiple options from a list
- **Text Input**: Short text responses
- **Text Area**: Long text responses
- **Number**: Numeric input with optional min/max validation constraints
- **Date**: Date selection
- **File**: Single file upload with validation
- **Multiple Files**: Multiple file uploads with validation
- **Phone Number**: Phone number input (string format)
- **Year**: Year selection with optional min/max validation
- **Email**: Email address input
- **URL**: Website URL input
- **Country**: Country selection (supports `in`/`not_in` operators for regional triggers)
- **Rating**: Rating scale input (e.g., 1-5, 1-10) with min/max validation
- **Datetime**: Combined date and time input (ISO 8601 format)
**Features:**
- Conditional visibility based on dependencies
- Review triggering based on answer values
- Conditional user guidance display
- Required/optional questions
- Ordered display
#### NUMBER, YEAR, and RATING Question Type Validation
NUMBER, YEAR, and RATING type questions support optional validation constraints for form generation and server-side validation:
- **min_value**: Minimum allowed numeric value (decimal field with 4 decimal places)
- **max_value**: Maximum allowed numeric value (decimal field with 4 decimal places)
- **Validation**: Server-side validation rejects answers outside the specified range
- **UI Integration**: Min/max values are exposed through serializers for client-side form constraints
- **Format Support**: NUMBER accepts integer and floating-point; YEAR and RATING accept integers
**Example API Usage - NUMBER:**
```http
POST /api/checklists-admin-questions/
Content-Type: application/json
{
"description": "Enter project budget (in thousands)",
"question_type": "number",
"checklist": "http://localhost:8000/api/checklists-admin/{checklist_uuid}/",
"required": true,
"min_value": "1.0",
"max_value": "10000.0",
"user_guidance": "Budget should be in thousands of dollars (e.g., 100 for $100,000)",
"order": 1
}
```
**Example API Usage - YEAR:**
```http
POST /api/checklists-admin-questions/
Content-Type: application/json
{
"description": "Year the organization was established",
"question_type": "year",
"checklist": "http://localhost:8000/api/checklists-admin/{checklist_uuid}/",
"required": true,
"min_value": "1900",
"max_value": "2030",
"order": 2
}
```
**Example API Usage - RATING:**
```http
POST /api/checklists-admin-questions/
Content-Type: application/json
{
"description": "Rate your satisfaction (1-5 stars)",
"question_type": "rating",
"checklist": "http://localhost:8000/api/checklists-admin/{checklist_uuid}/",
"required": true,
"min_value": "1",
"max_value": "5",
"user_guidance": "1 = Very Dissatisfied, 5 = Very Satisfied",
"order": 3
}
```
**Validation Scenarios:**
- Budget ranges (e.g., $1K - $10M) - NUMBER
- Percentages (0-100) - NUMBER
- Age ranges (18-100) - NUMBER
- Scientific measurements with decimal precision - NUMBER
- Year of establishment (1900-2030) - YEAR
- Satisfaction ratings (1-5 or 1-10 scale) - RATING
- Net Promoter Score (0-10) - RATING
#### FILE and MULTIPLE_FILES Question Type Validation
FILE and MULTIPLE_FILES type questions support comprehensive validation for secure file uploads with configurable restrictions:
- **allowed_file_types**: List of allowed file extensions (e.g., `['.pdf', '.doc', '.docx']`)
- **allowed_mime_types**: List of allowed MIME types for security (e.g., `['application/pdf', 'application/msword']`)
- **max_file_size_mb**: Maximum file size in megabytes per file
- **max_files_count**: Maximum number of files (MULTIPLE_FILES only)
**Security Features:**
- **Header-Based Validation**: Uses file content detection (via `python-magic`) rather than trusting extensions
- **Dual Validation**: When both extensions and MIME types are specified, files must match both criteria
- **Wildcard Support**: MIME types support wildcards like `image/*` for category-based validation
- **Spoofing Prevention**: Rejects files with mismatched extensions and MIME types (e.g., executable file renamed to `.pdf`)
**Example API Usage:**
```http
POST /api/checklists-admin-questions/
Content-Type: application/json
{
"description": "Upload compliance documents",
"question_type": "multiple_files",
"checklist": "http://localhost:8000/api/checklists-admin/{checklist_uuid}/",
"required": true,
"allowed_file_types": [".pdf", ".docx"],
"allowed_mime_types": ["application/pdf", "application/vnd.openxmlformats-officedocument.wordprocessingml.document"],
"max_file_size_mb": 25,
"max_files_count": 5,
"user_guidance": "Upload your compliance documentation. Accepted formats: PDF and Word documents.",
"order": 1
}
```
**File Answer Format:**
Users submit files as base64 encoded content. The system automatically detects MIME types and stores files securely.
Single file (FILE type):
```json
{
"name": "compliance_report.pdf",
"content": "JVBERi0xLjQKMSAwIG9iago8PAovVHlwZSAvQ2F0YWxvZwo+PgplbmRvYmoKeHJlZgowIDEKMDAwMDAwMDAwMCA2NTUzNSBmIAp0cmFpbGVyCjw8Ci9TaXplIDEKL1Jvb3QgMSAwIFIKPj4Kc3RhcnR4cmVmCjkKJSVFT0Y="
}
```
Multiple files (MULTIPLE_FILES type):
```json
[
{
"name": "technical_spec.pdf",
"content": "JVBERi0xLjQKMSAwIG9iago8PAovVHlwZSAvQ2F0YWxvZwo+PgplbmRvYmoKeHJlZgowIDEKMDAwMDAwMDAwMCA2NTUzNSBmIAp0cmFpbGVyCjw8Ci9TaXplIDEKL1Jvb3QgMSAwIFIKPj4Kc3RhcnR4cmVmCjkKJSVFT0Y="
},
{
"name": "user_manual.docx",
"content": "UEsDBBQABgAIAAAAIQAAAAAAAAAAAAAAAQAAABEAAABkb2NQcm9wcy9jb3JlLnhtbIFCwI9Z..."
}
]
```
After submission, the system processes files and stores metadata:
Processed single file response:
```json
{
"name": "compliance_report.pdf",
"size": 1234,
"mime_type": "application/pdf",
"stored_file_id": "550e8400-e29b-41d4-a716-446655440000"
}
```
**Validation Scenarios:**
- **Document Management**: Restrict to office documents with `["application/pdf", "application/msword", "application/vnd.openxmlformats-officedocument.wordprocessingml.document"]`
- **Image Upload**: Use `["image/*"]` to allow any image format while preventing executable files
- **Mixed Media**: Combine specific types like `["application/pdf", "image/jpeg", "image/png"]`
- **Size Control**: Set appropriate limits based on content type (e.g., 50MB for videos, 10MB for documents)
**Security Best Practices:**
1. **Always set MIME type restrictions** for security-critical uploads
2. **Use both extension and MIME type validation** for maximum security
3. **Set appropriate file size limits** to prevent resource abuse
4. **Limit file counts** for MULTIPLE_FILES to prevent overwhelming storage
5. **Use specific MIME types** rather than wildcards when possible for better security
#### PHONE_NUMBER, EMAIL, URL Question Types
These string-based question types provide semantic meaning for contact and web-related inputs:
**Example API Usage - Contact Information:**
```http
POST /api/checklists-admin-questions/
Content-Type: application/json
{
"description": "Primary contact phone number",
"question_type": "phone_number",
"checklist": "http://localhost:8000/api/checklists-admin/{checklist_uuid}/",
"required": true,
"user_guidance": "Include country code (e.g., +1 555-555-5555)",
"order": 1
}
```
```http
POST /api/checklists-admin-questions/
Content-Type: application/json
{
"description": "Contact email address",
"question_type": "email",
"checklist": "http://localhost:8000/api/checklists-admin/{checklist_uuid}/",
"required": true,
"order": 2
}
```
```http
POST /api/checklists-admin-questions/
Content-Type: application/json
{
"description": "Project website URL",
"question_type": "url",
"checklist": "http://localhost:8000/api/checklists-admin/{checklist_uuid}/",
"required": false,
"user_guidance": "Include the full URL with https://",
"order": 3
}
```
**Operator Support:**
- `equals`/`not_equals`: Exact match comparison
- `contains`: Substring matching (e.g., check if email contains "@company.com")
#### COUNTRY Question Type
The COUNTRY question type is designed for country/region selection with support for regional triggers:
**Example API Usage:**
```http
POST /api/checklists-admin-questions/
Content-Type: application/json
{
"description": "Country of operation",
"question_type": "country",
"checklist": "http://localhost:8000/api/checklists-admin/{checklist_uuid}/",
"required": true,
"user_guidance": "Select the primary country where your organization operates",
"order": 1
}
```
**Regional Trigger Example - EU Countries:**
```http
POST /api/checklists-admin-questions/
Content-Type: application/json
{
"description": "Country of operation",
"question_type": "country",
"required": true,
// Trigger GDPR review for EU countries
"review_answer_value": ["DE", "FR", "IT", "ES", "NL", "BE", "AT", "PL"],
"operator": "in",
"always_requires_review": false,
// Show GDPR guidance for EU countries
"user_guidance": "Since you operate in the EU, GDPR compliance is required.",
"always_show_guidance": false,
"guidance_answer_value": ["DE", "FR", "IT", "ES", "NL", "BE", "AT", "PL"],
"guidance_operator": "in"
}
```
**Operator Support:**
- `equals`/`not_equals`: Exact country match
- `in`/`not_in`: Check if country is in a set of countries (ideal for regional triggers)
#### DATETIME Question Type
The DATETIME question type captures both date and time in ISO 8601 format:
**Example API Usage:**
```http
POST /api/checklists-admin-questions/
Content-Type: application/json
{
"description": "Scheduled deployment date and time",
"question_type": "datetime",
"checklist": "http://localhost:8000/api/checklists-admin/{checklist_uuid}/",
"required": true,
"user_guidance": "Select the planned deployment date and time (timezone-aware)",
"order": 1
}
```
**Answer Format:**
```json
{
"question_uuid": "datetime-question-uuid",
"answer_data": "2024-06-15T14:30:00+00:00"
}
```
**Operator Support:**
- `equals`/`not_equals`: Exact datetime match
### QuestionOption
Multiple choice options for select-type questions with ordering support. Provides the available choices for single-select and multi-select questions.
### QuestionDependency
Conditional visibility logic - questions can depend on other questions' answers with circular dependency prevention. This enables dynamic questionnaires that adapt based on user responses.
**Operators supported:**
- `equals`: Exact match
- `not_equals`: Not equal to
- `contains`: Text contains substring
- `in`: Value exists in list
- `not_in`: Value does not exist in list
**Dependency Logic Operators:**
Questions with multiple dependencies can use different logic operators to determine visibility:
- `and` (default): **All conditions must be true** - Question is visible only when ALL dependencies are satisfied
- `or`: **Any condition must be true** - Question is visible when AT LEAST ONE dependency is satisfied
**Example**: A security question might be shown if the project handles personal data OR processes payments OR stores sensitive information.
### ChecklistCompletion
Generic completion tracking model that links checklists to any domain object (proposals, projects, etc.) using Django's generic foreign key system.
**Features:**
- Generic foreign key to any model (scope)
- Completion status tracking
- Review requirement detection
- Reviewer assignment and notes
- Completion percentage calculation
### Answer
User responses linked to ChecklistCompletion objects, stored as JSON with automatic review flagging and reviewer tracking.
**Features:**
- Flexible JSON storage for different answer types
- Automatic review requirement detection based on question configuration
- Review workflow with reviewer assignment and notes
- Audit trail with timestamps
- Answer validation based on question type
- Unique constraints per completion/question/user

### Integration via ViewSet Mixins
The core checklist module provides ViewSet mixins for integration into other apps:
**UserChecklistMixin** - For end users filling checklists:
- `GET /{app}/{uuid}/checklist/` - Get checklist questions with user's answers
- `GET /{app}/{uuid}/completion_status/` - Get completion status
- `POST /{app}/{uuid}/submit_answers/` - Submit answers (including answer removal)
- `GET /{app}/checklist-template/?parent_uuid={parent_uuid}` - Get checklist template for creating new objects
**ReviewerChecklistMixin** - For reviewers (with sensitive review logic):
- `GET /{app}/{uuid}/checklist_review/` - Get full checklist with review triggers
- `GET /{app}/{uuid}/completion_review_status/` - Get completion with review details
Examples:
- `GET /api/proposals/{uuid}/checklist/` - Get proposal checklist
- `POST /api/proposals/{uuid}/submit_answers/` - Submit proposal answers
- `GET /api/proposals/{uuid}/checklist_review/` - Review proposal checklist (reviewers only)
- `GET /api/projects/checklist-template/?parent_uuid={customer_uuid}` - Get project checklist template
## Checklist Templates for New Object Creation
The checklist system provides a template endpoint that enables frontend applications to retrieve checklist questions and visibility rules for creating new objects (e.g., projects) within a specific context (e.g., customer). This functionality allows for dynamic form generation where questions can be shown or hidden based on dependencies without requiring an existing object.
### Template Endpoint Usage
**Endpoint**: `GET /{app}/checklist-template/?parent_uuid={parent_uuid}`
**Parameters**:
- `parent_uuid` (required): UUID of the parent object that determines which checklist to use
**Example for Projects**:
```http
GET /api/projects/checklist-template/?parent_uuid=123e4567-e89b-12d3-a456-426614174000
```
**Response Structure**:
```json
{
"checklist": {
"uuid": "550e8400-e29b-41d4-a716-446655440000",
"name": "Project Metadata Checklist",
"description": "Required metadata for new projects",
"checklist_type": "project_metadata"
},
"questions": [
{
"uuid": "q1-uuid",
"description": "What is the project purpose?",
"user_guidance": "Please describe the main goals and objectives",
"question_options": []
},
{
"uuid": "q2-uuid",
"description": "Project category",
"user_guidance": null,
"question_options": [
{"uuid": "opt1", "label": "Research", "order": 1},
{"uuid": "opt2", "label": "Development", "order": 2},
{"uuid": "opt3", "label": "Production", "order": 3}
]
}
],
"initial_visible_questions": [
// Subset of questions that are visible initially (not dependent on other answers)
]
}
```
### Frontend Implementation Flow
1. **Form Initialization**: When users initiate object creation (e.g., "Create New Project"), call the template endpoint
2. **Dynamic Form Building**: Use the returned questions to build a dynamic form, initially showing only `initial_visible_questions`
3. **Answer-Based Visibility**: As users answer questions, use question dependencies to show/hide additional questions
4. **Object Creation**: After users complete the form, create the object via the standard creation endpoint
5. **Answer Submission**: Submit checklist answers using the existing `submit_answers` endpoint
### Implementation for Different Apps
Apps that use `UserChecklistMixin` can implement template support by overriding two methods:
```python
class ProjectViewSet(UserChecklistMixin, ActionsViewSet):
def get_checklist_for_new_object(self, parent_obj):
"""Return the checklist that will be used for new objects."""
# For projects, get checklist from customer configuration
if hasattr(parent_obj, "project_metadata_checklist"):
return parent_obj.project_metadata_checklist
return None
def get_parent_object_for_checklist(self, parent_uuid):
"""Return parent object for template lookup."""
# For projects, parent is customer
try:
return Customer.objects.get(uuid=parent_uuid)
except Customer.DoesNotExist:
return None
```
### Benefits
- **Single Request**: Get all necessary form information in one API call
- **Dynamic Forms**: Build responsive forms that adapt based on user input
- **Consistency**: Ensure all objects follow the same metadata requirements
- **Validation**: Frontend can validate required fields before object creation
- **Performance**: Avoid multiple API calls for form setup
### Error Responses
- **400 Bad Request**: Missing `parent_uuid` parameter or no checklist configured
- **404 Not Found**: Parent object not found
- **403 Forbidden**: User lacks permission to create objects in the specified context
## Question Dependencies
The system supports sophisticated conditional logic through question dependencies:
1. **Simple Dependencies**: Show Question B only if Question A equals specific value
2. **Complex Dependencies**: Multiple conditions with different operators and logic
3. **Circular Prevention**: Automatic detection and prevention of circular dependencies
4. **Dynamic Visibility**: Real-time question showing/hiding based on current answers
### Multiple Dependency Logic
Questions can have multiple dependencies evaluated using different logic operators:
#### AND Logic (Default)
Question visible only when **ALL** dependencies are satisfied:
```http
# Create question with AND logic (default)
POST /api/checklists-admin-questions/
{
"description": "Cloud security configuration details",
"question_type": "text_area",
"dependency_logic_operator": "and"
}
# Question visible only when user selects "cloud" AND "production"
POST /api/checklists-admin-question-dependencies/
{
"question": "http://localhost:8000/api/checklists-admin-questions/{security_question_uuid}/",
"depends_on_question": "http://localhost:8000/api/checklists-admin-questions/{environment_question_uuid}/",
"required_answer_value": "production",
"operator": "equals"
}
POST /api/checklists-admin-question-dependencies/
{
"question": "http://localhost:8000/api/checklists-admin-questions/{security_question_uuid}/",
"depends_on_question": "http://localhost:8000/api/checklists-admin-questions/{deployment_question_uuid}/",
"required_answer_value": "cloud",
"operator": "equals"
}
```
#### OR Logic
Question visible when **ANY** dependency is satisfied:
```http
# Create question with OR logic
POST /api/checklists-admin-questions/
{
"description": "Data protection measures",
"question_type": "multi_select",
"dependency_logic_operator": "or"
}
# Question visible when user handles personal data OR financial data OR health data
POST /api/checklists-admin-question-dependencies/
{
"question": "http://localhost:8000/api/checklists-admin-questions/{protection_question_uuid}/",
"depends_on_question": "http://localhost:8000/api/checklists-admin-questions/{data_type_question_uuid}/",
"required_answer_value": ["personal", "financial", "health"],
"operator": "in"
}
POST /api/checklists-admin-question-dependencies/
{
"question": "http://localhost:8000/api/checklists-admin-questions/{protection_question_uuid}/",
"depends_on_question": "http://localhost:8000/api/checklists-admin-questions/{compliance_question_uuid}/",
"required_answer_value": true,
"operator": "equals"
}
```
Example: A security questionnaire might show cloud-specific questions if the user indicates they use cloud services, and data protection questions if they handle sensitive data OR require compliance.
## Answer Management
### Answer Submission and Updates
Users can submit, update, and remove answers through the `submit_answers` endpoint:
```http
POST /api/{app}/{uuid}/submit_answers/
Content-Type: application/json
[
{
"question_uuid": "123e4567-e89b-12d3-a456-426614174000",
"answer_data": "New answer value"
},
{
"question_uuid": "456e7890-e12b-34c5-d678-901234567890",
"answer_data": null // Remove existing answer
}
]
```
### Answer Removal
Users can remove their answers by submitting `null` as the `answer_data` value. This performs a hard deletion of the answer record and automatically:
- **Recalculates completion percentage** - Removed answers no longer count toward completion
- **Updates completion status** - Required questions with removed answers mark checklist as incomplete
- **Updates review requirements** - Removing answers that triggered reviews clears the review flag
- **Maintains audit trail** - Through Answer model timestamps before deletion
**Key Features:**
- **Safe operations**: Attempting to remove non-existent answers succeeds without errors
- **Mixed operations**: Single request can create, update, and remove answers simultaneously
- **Validation bypass**: Null values skip validation since they indicate removal intent
- **Status synchronization**: Completion and review status automatically updated after changes
**Example - Mixed Operations:**
```http
POST /api/proposals/{uuid}/submit_answers/
[
{"question_uuid": "q1-uuid", "answer_data": true}, // Create/update
{"question_uuid": "q2-uuid", "answer_data": null}, // Remove
{"question_uuid": "q3-uuid", "answer_data": "New text"} // Create/update
]
```
## Review Workflow
Questions can be configured to trigger reviews based on answers:
1. **Automatic Review Triggers**: Specific answer values trigger review requirements
2. **Always Review**: Questions that always require review regardless of answer
3. **Review Assignment**: Staff can be assigned to review flagged answers
4. **Review Notes**: Internal notes and approval tracking
## Configuring Conditional Visibility via REST API
The checklist system supports sophisticated conditional logic through two mechanisms: **Question Dependencies** (for question visibility) and **Conditional User Guidance** (for guidance text display). Both use the same flexible operator-based system.
### Supported Operators
All conditional logic supports these operators, with specific question type compatibility:
- `equals` - Exact match
- **Compatible with**: NUMBER, DATE, BOOLEAN, FILE, YEAR, RATING, DATETIME, PHONE_NUMBER, EMAIL, URL, COUNTRY question types
- **Example**: Check if boolean answer is `true`, or if file name equals `"document.pdf"`
- `not_equals` - Not equal to
- **Compatible with**: NUMBER, DATE, BOOLEAN, FILE, YEAR, RATING, DATETIME, PHONE_NUMBER, EMAIL, URL, COUNTRY question types
- **Example**: Check if boolean answer is not `false`, or if file name is not `"template.pdf"`
- `contains` - Text contains substring
- **Compatible with**: TEXT_INPUT, TEXT_AREA, FILE, MULTIPLE_FILES, PHONE_NUMBER, EMAIL, URL question types
- **Example**: Check if text answer contains "sensitive", or if file name contains "confidential"
- **Note**: Case-sensitive matching
- `in` - Value exists in list
- **Compatible with**: SINGLE_SELECT, MULTI_SELECT, MULTIPLE_FILES, COUNTRY question types
- **Example**: Check if selected option is one of `["high", "critical", "urgent"]`, or if country is in `["DE", "FR", "IT"]`
- **Note**: For single-select, checks if the selected value is in the condition list
- **Note**: For multi-select and multiple files, checks if any selected value is in the condition list
- **Note**: For country, enables regional triggers (e.g., EU countries, specific regions)
- `not_in` - Value does not exist in list
- **Compatible with**: SINGLE_SELECT, MULTI_SELECT, MULTIPLE_FILES, COUNTRY question types
- **Example**: Check if selected option is not one of `["low", "minimal"]`, or if country is not in `["US", "CA"]`
- **Note**: For single-select, checks if the selected value is not in the condition list
- **Note**: For multi-select and multiple files, checks if none of the selected values are in the condition list
### Question Dependencies (Conditional Visibility)
Configure questions to show/hide based on answers to other questions.
#### Creating a Question Dependency
```http
POST /api/checklists-admin-question-dependencies/
Content-Type: application/json
{
"question": "http://localhost:8000/api/checklists-admin-questions/{dependent_question_uuid}/",
"depends_on_question": "http://localhost:8000/api/checklists-admin-questions/{trigger_question_uuid}/",
"required_answer_value": "yes",
"operator": "equals"
}
```
#### Example Scenarios
**1. Show cloud questions only if user selects "cloud" deployment:**
```http
POST /api/checklists-admin-question-dependencies/
{
"question": "http://localhost:8000/api/checklists-admin-questions/{cloud_provider_question_uuid}/",
"depends_on_question": "http://localhost:8000/api/checklists-admin-questions/{deployment_type_question_uuid}/",
"required_answer_value": "cloud",
"operator": "equals"
}
```
**2. Show security questions if user indicates sensitive data:**
```http
POST /api/checklists-admin-question-dependencies/
{
"question": "http://localhost:8000/api/checklists-admin-questions/{security_measures_question_uuid}/",
"depends_on_question": "http://localhost:8000/api/checklists-admin-questions/{has_sensitive_data_question_uuid}/",
"required_answer_value": true,
"operator": "equals"
}
```
**3. Show budget questions for high-value options:**
```http
POST /api/checklists-admin-question-dependencies/
{
"question": "http://localhost:8000/api/checklists-admin-questions/{budget_approval_question_uuid}/",
"depends_on_question": "http://localhost:8000/api/checklists-admin-questions/{project_category_question_uuid}/",

{
"description": "Does your project handle personal data?",
"question_type": "boolean",
"checklist": "http://localhost:8000/api/checklists-admin/{checklist_uuid}/",
"user_guidance": "Personal data includes names, emails, addresses, and any identifiable information.",
"always_show_guidance": true,
"order": 1,
"required": true
}
```
#### Creating a Question with Conditional Guidance
```http
POST /api/checklists-admin-questions/
Content-Type: application/json
{
"description": "What type of deployment will you use?",
"question_type": "single_select",

"always_show_guidance": false,
"guidance_answer_value": "cloud",
"guidance_operator": "equals",
"order": 2,
"required": true
}
```
#### Updating Conditional Guidance
```http
PATCH /api/checklists-admin-questions/{question_uuid}/
Content-Type: application/json
{
"user_guidance": "Updated guidance text for enterprise projects",
"always_show_guidance": false,
"guidance_answer_value": "enterprise",
"guidance_operator": "equals"
}
```
#### Example Scenarios
**1. Show compliance guidance only for "Yes" answers:**
```http
POST /api/checklists-admin-questions/
{
"description": "Will you be processing EU citizen data?",
"question_type": "boolean",
"user_guidance": "Since you're processing EU data, you must comply with GDPR requirements. Please review our GDPR compliance checklist.",
"always_show_guidance": false,
"guidance_answer_value": true,
"guidance_operator": "equals"
}
```
**2. Show warning guidance for multiple selections:**
```http
POST /api/checklists-admin-questions/

}
```
### Complex Scenarios
#### Multi-Level Dependencies
Create cascading question visibility:
```http
# First level: Show cloud questions if deployment is cloud
POST /api/checklists-admin-question-dependencies/
{
"question": "http://localhost:8000/api/checklists-admin-questions/{cloud_provider_question_uuid}/",
"depends_on_question": "http://localhost:8000/api/checklists-admin-questions/{deployment_type_question_uuid}/",

"question": "http://localhost:8000/api/checklists-admin-questions/{aws_region_question_uuid}/",
"depends_on_question": "http://localhost:8000/api/checklists-admin-questions/{cloud_provider_question_uuid}/",
"required_answer_value": "aws",
"operator": "equals"
}
```
#### File-Based Conditional Logic
Configure questions to show or trigger reviews based on file uploads:
**Show additional questions if specific file types are uploaded:**
```http
# Base file upload question
POST /api/checklists-admin-questions/
{
"description": "Upload your project documentation",
"question_type": "multiple_files",
"allowed_file_types": [".pdf", ".docx", ".pptx"],

"max_file_size_mb": 50,
"max_files_count": 10,
"order": 1
}
# Show compliance questions if any file contains "confidential"
POST /api/checklists-admin-question-dependencies/
{
"question": "http://localhost:8000/api/checklists-admin-questions/{compliance_question_uuid}/",
"depends_on_question": "http://localhost:8000/api/checklists-admin-questions/{file_upload_question_uuid}/",
"required_answer_value": "confidential",
"operator": "contains"
}
```
**Trigger reviews for sensitive document uploads:**
```http
POST /api/checklists-admin-questions/
{
"description": "Upload technical specifications",
"question_type": "file",
"allowed_file_types": [".pdf", ".docx"],
"allowed_mime_types": ["application/pdf", "application/vnd.openxmlformats-officedocument.wordprocessingml.document"],
"max_file_size_mb": 25,
// Trigger review if filename contains sensitive keywords
"review_answer_value": ["secret", "confidential", "proprietary"],
"operator": "contains",
"always_requires_review": false,
// Show guidance for sensitive uploads
"user_guidance": "⚠️ This file appears to contain sensitive information and will require additional review.",
"always_show_guidance": false,
"guidance_answer_value": ["secret", "confidential", "proprietary"],
"guidance_operator": "contains"
}
```
**File size and count-based dependencies:**
```http
# Show budget approval question if large files are uploaded
POST /api/checklists-admin-question-dependencies/
{
"question": "http://localhost:8000/api/checklists-admin-questions/{budget_approval_question_uuid}/",
"depends_on_question": "http://localhost:8000/api/checklists-admin-questions/{large_files_question_uuid}/",
"required_answer_value": ["presentation.pptx", "video.mp4", "dataset.zip"],
"operator": "in"
}
```
#### Combined Review Triggers and Guidance
Configure a question that both shows guidance and triggers reviews:
```http
POST /api/checklists-admin-questions/
{
"description": "Does your application handle financial transactions?",
"question_type": "boolean",
"required": true,
// Conditional guidance
"user_guidance": "Financial transaction handling requires PCI DSS compliance and additional security reviews.",
"always_show_guidance": false,
"guidance_answer_value": true,
"guidance_operator": "equals",
// Review trigger (same condition)
"review_answer_value": true,
"operator": "equals",
"always_requires_review": false
}
```
### API Response Examples
When questions are retrieved through user-facing endpoints, conditional logic is automatically applied:
**Question with visible guidance:**
```json
{
"uuid": "123e4567-e89b-12d3-a456-426614174000",
"description": "What is your deployment type?",
"question_type": "single_select",
"user_guidance": "Since you selected cloud deployment, review our cloud security guidelines.",
"existing_answer": {
"answer_data": "cloud"
},
"question_options": [
{"uuid": "...", "label": "On-premise", "order": 1},
{"uuid": "...", "label": "Cloud", "order": 2},
{"uuid": "...", "label": "Hybrid", "order": 3}
]
}
```
**Question with hidden guidance (condition not met):**
```json
{
"uuid": "123e4567-e89b-12d3-a456-426614174000",
"description": "What is your deployment type?",
"question_type": "single_select",
"user_guidance": null,
"existing_answer": {
"answer_data": "on-premise"
},
"question_options": [...]
}
```
## Configuring Review Triggers and User Guidance
Beyond conditional visibility, questions can be configured with **review triggers** (to flag answers for staff review) and **conditional user guidance** (to show context-sensitive help text). Both features use the same operator system for maximum flexibility.
### Review Trigger Configuration
Review triggers automatically flag specific answers for staff review, enabling compliance workflows and quality control.

"checklist": "http://localhost:8000/api/checklists-admin/{checklist_uuid}/",
"required": true,
"always_requires_review": true,
"order": 1
}
```
**2. Conditional Review Trigger:**
```http
POST /api/checklists-admin-questions/

}
```
### Best Practices
#### Review Trigger Design
1. **Clear Criteria**: Use specific, unambiguous trigger conditions
2. **Risk-Based**: Focus triggers on high-risk or compliance-critical answers
3. **Consistent Operators**: Use the same operators across similar question types
4. **Documentation**: Include internal notes about why specific answers trigger reviews
#### User Guidance Best Practices
1. **Actionable**: Provide specific next steps, not just information
2. **Contextual**: Tailor guidance to the specific answer given
3. **Timely**: Show guidance when users need it most
4. **Resource Links**: Include references to relevant documentation or contacts
#### Workflow Integration
1. **Progressive Disclosure**: Use conditional visibility with guidance to reduce cognitive load
2. **Layered Validation**: Combine client-side guidance with server-side review triggers
3. **Clear Feedback**: Ensure users understand when answers will be reviewed
4. **Review Efficiency**: Design triggers to minimize false positives for reviewers
## Permission System
Access control is implemented through:
- **Staff Administration**: Direct checklist management restricted to staff users
- **App-level Integration**: Checklist access controlled via host application permissions
- **Mixin-based Permissions**: Apps define their own permission requirements for checklist actions
- **Review Segregation**: Separate permissions for users vs reviewers to hide sensitive review logic
## Validation and Data Integrity
The system includes comprehensive validation:
- **Answer Type Validation**: Ensures answers match expected question types
- **Required Question Enforcement**: Prevents submission of incomplete required questions
- **UUID Validation**: Proper UUID format checking for references
- **Circular Dependency Prevention**: Automatic detection of invalid dependency chains
## Integration with Waldur Apps
The checklist system integrates with various Waldur applications:
- **Generic Foreign Key System**: Can be attached to any Django model (proposals, projects, resources, etc.)
- **ViewSet Mixins**: Easy integration through `UserChecklistMixin` and `ReviewerChecklistMixin`
- **Flexible Completion Tracking**: Each integration controls its own completion lifecycle
- **Permission Delegation**: Host applications define appropriate permission checks
### Marketplace Offering Integration
The checklist system provides special integration with marketplace offerings to enforce compliance requirements:
#### Offering Compliance Checklists
Offerings can be associated with compliance checklists to ensure service providers meet organizational requirements:
- **Compliance Checklist Assignment**: Offerings can reference a specific `offering_compliance` checklist
- **Compliance Tracking**: Service providers can monitor compliance rates across all their offerings
- **User-level Compliance**: Each offering user's completion status is tracked individually
#### API Integration
**Offering Serialization:**
- The `compliance_checklist` field is exposed in offering serializers as a hyperlinked relationship
- The `has_compliance_requirements` boolean field indicates whether an offering has compliance requirements
**Service Provider Compliance Endpoints:**
- `GET /api/marketplace-service-providers/{uuid}/compliance/compliance_overview/` - Get paginated compliance overview for all offerings
- Shows compliance statistics for each offering with a checklist
- Includes total users, users with completions, completed users, and compliance rate percentage
- Supports pagination parameters (`page`, `page_size`) with database-level optimization
**Example Response:**
```json
[
{
"offering_uuid": "123e4567-e89b-12d3-a456-426614174000",
"offering_name": "Cloud Storage Service",
"checklist_name": "Cloud Service Compliance",
"total_users": 50,
"users_with_completions": 45,
"completed_users": 40,
"pending_users": 5,
"compliance_rate": 80.0
}
]
```
#### Updating Offering Compliance Checklist
Service providers can update the compliance checklist for their offerings:
```http
POST /api/marketplace-offerings/{uuid}/update_compliance_checklist/
Content-Type: application/json
{
"compliance_checklist": "550e8400-e29b-41d4-a716-446655440000"
}
```
## Usage Patterns
### Basic Integration Flow
1. **Admin Setup**: Staff creates checklists with questions, dependencies, and review triggers
2. **App Integration**: Host app (e.g., proposals) creates `ChecklistCompletion` objects linking checklists to domain objects
3. **User Interaction**: End users access checklists through app-specific endpoints using `UserChecklistMixin`
4. **Answer Submission**: Users submit answers, triggering automatic completion status updates
5. **Review Process**: Reviewers access full checklist information through `ReviewerChecklistMixin`
6. **Completion Tracking**: Host apps monitor completion status and take appropriate actions
### File Upload Integration Flow
For file upload questions, the integration includes additional security validation:
1. **Frontend Upload**: Client uploads files to secure storage (e.g., S3, database storage)
2. **File Validation**: Server validates file headers using `python-magic` for MIME type detection
3. **Security Check**: System verifies both file extension and MIME type match allowed criteria
4. **Answer Submission**: File metadata (name, size, MIME type, URL) submitted as answer data
5. **Review Triggers**: Files with sensitive names or large sizes trigger automatic review
6. **Compliance Tracking**: System tracks which files were uploaded for compliance auditing
**File Answer Submission Example:**
```json
POST /api/proposals/{uuid}/submit_answers/
[
{
"question_uuid": "file-upload-question-uuid",
"answer_data": {
"name": "compliance_report.pdf",
"content": "JVBERi0xLjQKMSAwIG9iago8PAovVHlwZSAvQ2F0YWxvZwo+PgplbmRvYmoKeHJlZgowIDEKMDAwMDAwMDAwMCA2NTUzNSBmIAp0cmFpbGVyCjw8Ci9TaXplIDEKL1Jvb3QgMSAwIFIKPj4Kc3RhcnR4cmVmCjkKJSVFT0Y="
}
},
{
"question_uuid": "multiple-files-question-uuid",
"answer_data": [
{
"name": "technical_spec.pdf",
"content": "JVBERi0xLjQKMSAwIG9iago8PAovVHlwZSAvQ2F0YWxvZwo+PgplbmRvYmoKeHJlZgowIDEKMDAwMDAwMDAwMCA2NTUzNSBmIAp0cmFpbGVyCjw8Ci9TaXplIDEKL1Jvb3QgMSAwIFIKPj4Kc3RhcnR4cmVmCjkKJSVFT0Y="
},
{
"name": "user_guide.docx",
"content": "UEsDBBQABgAIAAAAIQAAAAAAAAAAAAAAAQAAABEAAABkb2NQcm9wcy9jb3JlLnhtbIFCwI9Z..."
}
]
}
]
```
The system automatically:
1. **Decodes base64 content** and validates file integrity
2. **Detects MIME types** from file headers using `python-magic`
3. **Validates against restrictions** (file types, MIME types, sizes)
4. **Stores files securely** in Waldur's media system
5. **Returns metadata** (no longer contains base64 content)
### Example Integration (Proposals)
```python
# proposals/models.py
class Proposal(models.Model):
# ... other fields
checklist_completion = models.OneToOneField(
ChecklistCompletion,
on_delete=models.CASCADE,
null=True, blank=True
)
# proposals/views.py
class ProposalViewSet(UserChecklistMixin, ReviewerChecklistMixin, ActionsViewSet):
# User permissions
checklist_permissions = [permission_factory(PermissionEnum.MANAGE_PROPOSAL)]
submit_answers_permissions = [permission_factory(PermissionEnum.MANAGE_PROPOSAL)]
# Reviewer permissions
checklist_review_permissions = [permission_factory(PermissionEnum.REVIEW_PROPOSALS)]
```
## Technical Implementation
The module follows Waldur's standard architecture patterns:
- **Django Models**: Standard ORM with mixins (UuidMixin, DescribableMixin, TimeStampedModel)
- **Generic Foreign Keys**: Flexible linking to any Django model through ChecklistCompletion
- **DRF Serializers**: REST API serialization with context-aware field exposure
- **ViewSet Mixins**: Reusable mixins for consistent integration across applications
- **Admin-Only Core APIs**: Direct checklist management restricted to staff
- **Permissions**: Delegated to host applications with mixin-based controls
- **Filtering**: Advanced filtering for admin interfaces
- **Validation**: Answer validation based on question types and business rules
### Architecture Principles
- **Separation of Concerns**: Core checklist logic separated from app-specific business logic
- **Flexible Integration**: Generic foreign keys allow attachment to any model
- **Security by Design**: Review logic hidden from users, exposed only to authorized reviewers
- **Extensible Question Types**: Support for multiple answer formats with validation
- **Dependency Management**: Sophisticated conditional logic with circular prevention
The system is designed for scalability and extensibility, supporting complex compliance scenarios while maintaining ease of integration for host applications.

### STOMP-Based Event Notification System
# STOMP-Based Event Notification System
## System Overview
The [STOMP](https://stomp.github.io/)-based event notification system enables Waldur to communicate changes to resources, orders, user roles, and other events to external systems via message queues. This eliminates the need for constant polling and enables immediate reactions to events in distributed architectures.
The key components include:
1. **STOMP Publisher (Waldur side)**: Located in the [waldur_core/logging/utils.py](https://github.com/waldur/waldur-mastermind/blob/73f2a0a7df04405b1c9ed5d2512d6213d649d398/src/waldur_core/logging/utils.py#L88) file, this component publishes messages to STOMP queues when specific events occur.
2. **Event Subscription Service**: Manages subscriptions to events by creating unique topics for each type of notification. Related file: event subscription management via API: [waldur_core/logging/views.py](https://github.com/waldur/waldur-mastermind/blob/73f2a0a7df04405b1c9ed5d2512d6213d649d398/src/waldur_core/logging/views.py#L193)
3. **STOMP Consumer (External System)**: Any external system that subscribes to these topics and processes incoming messages. This can be:
- The `waldur-site-agent` running on resource provider infrastructure
- Custom integration services (e.g., SharePoint integration, external notification systems)
- Third-party systems that need to react to Waldur events
## Event Flow
1. An event occurs in Waldur (e.g., a new order is created, a user role changes, or a resource is updated)
2. Waldur publishes a message to the appropriate STOMP queue(s)
3. External systems (agents, integrations, or third-party services) receive the message and process it based on the event type
4. The consuming system executes the necessary actions based on the message content
## Queue Naming Strategy
The system follows an **object-based naming convention** for STOMP queues rather than event-based naming. This design choice provides several benefits:
- **Simplified Client Configuration**: Clients subscribe to object types (e.g., `resource_periodic_limits`) rather than specific event types
- **Action Flexibility**: Specific actions (e.g., `apply_periodic_settings`, `update_limits`) are stored in the message payload
- **Easier Maintenance**: Adding new actions doesn't require queue reconfiguration
- **Future Migration Path**: Sets foundation for eventual migration to event-based naming without immediate client changes
**Current Approach:**
- Queue: `resource_periodic_limits`
- Payload: `{"action": "apply_periodic_settings", "settings": {...}}`
**Alternative Event-Based Approach** (for future consideration):
- Queue: `resource_periodic_limits_update`
- More specific but requires client reconfiguration for each new event type
## Message Types
The system handles several types of events:
1. **Order Messages** (`order`): Notifications about marketplace orders (create, update, terminate)
2. **User Role Messages** (`user_role`): Changes to user permissions in projects
3. **Resource Messages** (`resource`): Updates to resource configuration or status
4. **Resource Periodic Limits** (`resource_periodic_limits`): SLURM periodic usage policy updates with allocation and limit settings
5. **Offering User Messages** (`offering_user`): Creation, updates, and deletion of offering users
6. **Service Account Messages** (`service_account`): Service account lifecycle events
7. **Course Account Messages** (`course_account`): Course account management events
8. **Importable Resources Messages** (`importable_resources`): Backend resource discovery events
## Implementation Details
### Publishing Messages (Waldur Side)
Events are published through a standardized mechanism in Waldur:
1. **Event Detection**: Events are triggered by Django signal handlers throughout the system
2. **Message Preparation**: Event data is serialized into JSON format with standardized payload structure
3. **Queue Publishing**: Messages are sent to appropriate queues using the `publish_messages` Celery task
The core publishing function is located in `src/waldur_core/logging/tasks.py:118` and utilizes the `publish_stomp_messages` utility in `src/waldur_core/logging/utils.py:93`.
### Offering User Event Messages
Offering user events are published when offering users are created, updated, or deleted. These handlers are located in [waldur_mastermind/marketplace/handlers.py](https://github.com/waldur/waldur-mastermind/blob/develop/src/waldur_mastermind/marketplace/handlers.py):
- `send_offering_user_created_message` - Triggers when an OfferingUser is created
- `send_offering_user_updated_message` - Triggers when an OfferingUser is updated
- `send_offering_user_deleted_message` - Triggers when an OfferingUser is deleted
- `send_user_attribute_update_message` - Triggers when a User's profile attributes change
(connected to `core.User` post_save, not `OfferingUser`)
**Message Payload Structure for create/update/delete Events:**
```json
{
"offering_user_uuid": "uuid-hex-string",
"user_uuid": "user-uuid-hex-string",
"username": "generated-username",
"state": "OK|Requested|Creating|...",
"action": "create|update|delete",
"attributes": {"email": "user@example.com", "first_name": "Alice"}, // create only
"changed_fields": ["field1", "field2"] // update only
}
```
**Message Payload Structure for attribute_update Events:**
When a User's profile fields change, a separate event is published for each offering
the user belongs to. The `OfferingUserAttributeConfig` for the offering determines which
changed fields are included.
```json
{
"offering_user_uuid": "uuid-hex-string",
"user_uuid": "user-uuid-hex-string",
"username": "generated-username",
"action": "attribute_update",
"changed_attributes": ["email", "first_name"],
"attributes": {"email": "new@example.com", "first_name": "Alice"}
}
```
**Event Triggers:**
- **Create**: When a new offering user account is created for a user in an offering
- **Update**: When any field of an existing offering user is modified (username, state, etc.)
- **Delete**: When an offering user account is removed from an offering
- **Attribute Update**: When a User's profile fields change, filtered through each offering's `OfferingUserAttributeConfig`
### Resource Periodic Limits Event Messages
Resource periodic limits events are published when SLURM periodic usage policies are applied to resources. These messages contain calculated SLURM settings including allocation limits, fairshare values, and QoS thresholds. The handler is located in [waldur_mastermind/policy/models.py](https://github.com/waldur/waldur-mastermind/blob/develop/src/waldur_mastermind/policy/models.py).
**Message Payload Structure for Resource Periodic Limits:**
```json
{
"resource_uuid": "resource-uuid-hex-string",
"backend_id": "slurm-account-name",
"offering_uuid": "offering-uuid-hex-string",
"action": "apply_periodic_settings",
"timestamp": "2024-01-01T00:00:00.000000",
"settings": {
"fairshare": 333,
"limit_type": "GrpTRESMins",
"grp_tres_mins": {
"billing": 119640
},
"qos_threshold": {
"billing": 119640
},
"grace_limit": {
"billing": 143568
},
"carryover_details": {
"carryover_applied": true,
"previous_period": "2023-Q4",
"previous_usage": 750.0,
"decay_factor": 0.015625,
"effective_previous_usage": 11.7,
"unused_allocation": 988.3,
"base_allocation": 1000.0,
"total_allocation": 1988.3
}
}
}
```
**Event Triggers:**
- **Policy Application**: When a SLURM periodic usage policy calculates new allocation limits and sends them to the site agent
- **Carryover Calculation**: When unused allocation from previous periods is calculated with decay factors
- **Limit Updates**: When fairshare values, TRES limits, or QoS thresholds need to be updated on the SLURM backend
### Subscription Management (Consumer Side)
External systems consuming events can be implemented with different levels of sophistication:
#### 1. Simple Event Subscription (Basic Integration)
For basic integrations, implement a direct subscription pattern:
```python
from waldur_api_client import AuthenticatedClient
from waldur_api_client.models import ObservableObjectTypeEnum
import stomp
# Create event subscription
client = AuthenticatedClient(base_url="https://api.waldur.com", token="your-token")
subscription = create_event_subscription(
client,
ObservableObjectTypeEnum.ORDER # or other types
)
# Setup STOMP connection
connection = stomp.WSStompConnection(
host_and_ports=[(stomp_host, stomp_port)],
vhost=subscription.user_uuid.hex
)
# Implement message listener
class EventListener(stomp.ConnectionListener):
def on_message(self, frame):
message_data = json.loads(frame.body)
# Process message based on action and content
handle_event(message_data)
```
#### 2. Structured Agent Pattern (Advanced Integration)
For more complex systems that need structured management and monitoring, use the **AgentIdentity** framework pattern from waldur-site-agent:
```python
import datetime
from waldur_api_client.models import AgentIdentityRequest, AgentServiceCreateRequest, AgentProcessorCreateRequest
from waldur_api_client.api.marketplace_site_agent_identities import (
marketplace_site_agent_identities_create,
marketplace_site_agent_identities_register_service,
)
from waldur_api_client.api.marketplace_site_agent_services import (
marketplace_site_agent_services_register_processor,
)
# Register agent identity
agent_identity_data = AgentIdentityRequest(
offering=offering_uuid,
name="my-integration-agent",
version="1.0.0",
dependencies=["stomp", "requests"],
last_restarted=datetime.datetime.now(),
config_file_path="/etc/my-agent/config.yaml",
config_file_content="# agent configuration"
)
agent_identity = marketplace_site_agent_identities_create.sync(
body=agent_identity_data,
client=waldur_rest_client
)
# Register agent service for event processing
service_name = f"event_process-{observable_object_type}"
agent_service = marketplace_site_agent_identities_register_service.sync(
uuid=agent_identity.uuid.hex,
body=AgentServiceCreateRequest(
name=service_name,
mode="event_process"
),
client=waldur_rest_client
)
# Register processors within the service
processor = marketplace_site_agent_services_register_processor.sync(
uuid=agent_service.uuid.hex,
body=AgentProcessorCreateRequest(
name="order-processor",
backend_type="CUSTOM_BACKEND",
backend_version="2.0"
),
client=waldur_rest_client
)
```
**Benefits of AgentIdentity Pattern:**
- **Monitoring**: Track agent health, version, and dependencies in Waldur
- **Service Management**: Organize multiple services within a single agent
- **Processor Tracking**: Monitor individual processors and their backend versions
- **Configuration Management**: Store and version configuration files
- **Statistics**: Collect and report agent performance metrics
### Message Processing (Consumer Side)
When a message arrives, it should be routed to appropriate handlers based on the event type and action. The message structure includes:
- **Event Type**: Determined by the observable object type (`order`, `user_role`, `resource`, etc.)
- **Action**: Specific operation to perform (`create`, `update`, `delete`, `apply_periodic_settings`, etc.)
- **Payload**: Event-specific data needed to process the action
**Message Processing Patterns:**
The system supports different message processing approaches based on complexity:
```python
# 1. Simple message processing (lightweight integration pattern)
class SimpleEventListener(stomp.ConnectionListener):
def on_message(self, frame):
try:
message_data = json.loads(frame.body)
message_type = self.get_message_type_from_queue(frame.headers.get('destination'))
if message_type == 'order':
self.handle_order(message_data)
elif message_type == 'user_role':
self.handle_user_role(message_data)
except Exception as e:
logger.error(f"Error processing message: {e}")
# 2. Structured agent processing (waldur-site-agent pattern)
OBJECT_TYPE_TO_HANDLER = {
"order": handle_order_message_stomp,
"user_role": handle_user_role_message_stomp,
"resource": handle_resource_message_stomp,
"resource_periodic_limits": handle_resource_periodic_limits_stomp,
"service_account": handle_account_message_stomp,
"course_account": handle_account_message_stomp,
"importable_resources": handle_importable_resources_message_stomp,
}
def route_message(frame, offering, user_agent):
"""Route message to appropriate handler based on destination."""
destination = frame.headers.get(HDR_DESTINATION, "")
# Extract object type from queue name: subscription_xxx_offering_yyy_OBJECT_TYPE
object_type = destination.split('_')[-1] if '_' in destination else ""
handler = OBJECT_TYPE_TO_HANDLER.get(object_type)
if handler:
handler(frame, offering, user_agent)
else:
logger.warning(f"No handler found for object type: {object_type}")
```
## API Endpoints
The event notification system provides REST API endpoints for managing event-based functionality (verified from OpenAPI specification):
### Event Subscriptions
- **GET /api/event-subscriptions/** - List event subscriptions
- **POST /api/event-subscriptions/** - Create new event subscription
- **GET /api/event-subscriptions/{uuid}/** - Retrieve specific subscription
- **PATCH /api/event-subscriptions/{uuid}/** - Update subscription settings
- **DELETE /api/event-subscriptions/{uuid}/** - Delete subscription
### Agent Identity Management
- **GET /api/marketplace-site-agent-identities/** - List agent identities
- **POST /api/marketplace-site-agent-identities/** - Register new agent identity
- **GET /api/marketplace-site-agent-identities/{uuid}/** - Retrieve agent identity
- **PATCH /api/marketplace-site-agent-identities/{uuid}/** - Update agent identity
- **DELETE /api/marketplace-site-agent-identities/{uuid}/** - Delete agent identity
- **POST /api/marketplace-site-agent-identities/{uuid}/register_service/** - Register service within agent
- **POST /api/marketplace-site-agent-identities/{uuid}/register_event_subscription/** - Register event subscription for agent
#### Agent Identity Permissions
Agent identity management uses a four-tier permission model checked by `_can_manage_offering_agent()`:
| Tier | Who | Scope |
|------|-----|-------|
| 1. Staff | `user.is_staff` | All offerings, all identities |
| 2. Customer owner | `CREATE_OFFERING` permission on offering's customer | All identities for customer's offerings |
| 3. Offering manager | `UPDATE_OFFERING` permission on the offering | All identities for that offering |
| 4. ISD identity manager | `is_identity_manager=True` + non-empty `managed_isds` | Own identities only, non-archived/draft offerings |
ISD identity managers can create agent identities for offerings in Active, Paused, or Unavailable states without requiring pre-existing offering users. This enables bootstrapping: agents create offering users, so requiring offering users to register agents would be a chicken-and-egg problem.
#### Agent Identity Ownership
Each `AgentIdentity` has a `created_by` field tracking the user who created it. This field is used to scope ISD identity manager access:
- **Create**: Any ISD identity manager can create an agent identity for an allowed offering
- **Update/Delete**: ISD identity managers can only modify or delete their own agent identities (`created_by == request.user`)
- **List**: ISD identity managers only see their own agent identities in query results
Staff, customer owners, and offering managers are not restricted by `created_by` — they can manage all agent identities within their scope.
### Agent Services
- **GET /api/marketplace-site-agent-services/** - List agent services
- **GET /api/marketplace-site-agent-services/{uuid}/** - Retrieve service details

## Technical Components
1. **WebSocket Transport**: The system uses STOMP over WebSockets for communication
2. **TLS Security**: Connections can be secured with TLS
3. **User Authentication**: Each subscription has its own credentials and permissions in RabbitMQ
4. **Queue Structure**: Queue names follow the pattern `/queue/subscription_{subscription_uuid}_offering_{offering_uuid}_{observable_object_type}`
Example queue names:
- `/queue/subscription_abc123_offering_def456_order`
- `/queue/subscription_abc123_offering_def456_user_role`
- `/queue/subscription_abc123_offering_def456_resource_periodic_limits`
## Error Handling and Resilience
The system includes:
- Graceful connection handling
- Signal handlers for proper shutdown
- Retry mechanisms for order processing — erred orders can be explicitly retried via `POST /api/marketplace-orders/{uuid}/retry/` for offering types that opt in with `supports_order_retry=True` (see [Retrying Erred Orders](marketplace.md#retrying-erred-orders))
- Error logging and optional Sentry integration
## Integration Examples
### Real-world Implementations
1. **Waldur Site Agent**: Full-featured agent for SLURM/HPC resource management
- Manages compute allocations, user accounts, and resource limits
- Implements structured AgentIdentity pattern with services and processors
- Handles complex periodic usage policies and carryover calculations
2. **External Billing Systems**: Automated billing updates
- Subscribes to resource usage and order events
- Updates external accounting systems in real-time
- Reduces manual billing reconciliation
3. **Custom Integration Services**: Lightweight integration patterns
- Process marketplace orders to create external resources
- Use simple subscription patterns for specific event types
- Demonstrate flexible integration approaches
## Manual Resource Synchronization
While the STOMP-based event system handles automatic synchronization, there are cases where manual synchronization is needed—for example, when investigating desynchronization issues or after network outages.
### Pull Endpoint
The marketplace provides a manual sync endpoint for resources:
```text
POST /api/marketplace-resources/{uuid}/pull/
```
**Response Codes:**
| Code | Description |
|------|-------------|
| 202 Accepted | Pull operation was successfully scheduled |
| 409 Conflict | Pull operation is not implemented for this offering type |
**Prerequisites:**
- Resource state must be `OK` or `ERRED`
- Resource must have a `backend_id` set
### Site Agent Resource Sync Flow
```mermaid
sequenceDiagram
participant User
participant Frontend as Homeport UI
participant WaldurAPI
participant Celery
participant STOMP as Message Queue
participant SiteAgent as Site Agent
User->>Frontend: Click "Sync" button
Frontend->>WaldurAPI: POST /api/marketplace-resources/{uuid}/pull/
WaldurAPI->>WaldurAPI: Validate resource state
WaldurAPI->>Celery: Schedule AgentResourcePullExecutor
WaldurAPI-->>Frontend: 202 Accepted
Celery->>STOMP: Publish resource sync request
STOMP->>SiteAgent: Deliver message
SiteAgent->>SiteAgent: Fetch current resource state
SiteAgent->>WaldurAPI: PUT /api/marketplace-resources/{uuid}/
WaldurAPI-->>SiteAgent: Resource updated
Note over User,SiteAgent: Resource now synchronized
```
### How Site Agent Pull Works
The pull operation for site agent resources works differently from direct backend integrations:
1. **No Direct Backend Access**: Waldur doesn't have direct access to site agent backends (e.g., SLURM clusters)
2. **Message-Based Sync**: Instead, a sync request message is published to the STOMP queue
3. **Agent Response**: The site agent receives the message, queries the actual backend, and reports the current state back to Waldur
**Backend Registration** (in `marketplace_site_agent/apps.py`):
```python
manager.register(
SITE_AGENT_OFFERING,
# ... other processors ...
pull_resource_executor=executors.AgentResourcePullExecutor,
)
```
**Executor Implementation** (in `marketplace_site_agent/executors.py`):
```python
class AgentResourcePullExecutor(MarketplaceActionExecutor):
@classmethod
def get_task_signature(cls, instance, serialized_instance, **kwargs):
return tasks.sync_resource.si(serialized_instance)
```
### Use Cases
1. **L1 Support**: Quickly verify resource state matches backend during incident investigation
2. **Post-Outage Recovery**: Manually trigger sync after network or service disruptions
3. **Debugging**: Confirm that the STOMP messaging pipeline is working correctly
4. **Data Reconciliation**: Force update when automatic sync may have missed changes
## Reliability and Self-Healing Features
The STOMP publishing system includes several features for improved reliability and self-healing capabilities.
### Circuit Breaker Pattern
A circuit breaker protects the system when RabbitMQ is unavailable:
- **CLOSED**: Normal operation, messages are published
- **OPEN**: RabbitMQ failures detected, messages are skipped to prevent cascading failures
- **HALF_OPEN**: Testing recovery, allowing limited messages through
Configuration (in `waldur_core/logging/circuit_breaker.py`):
- `failure_threshold`: 5 consecutive failures to trip the circuit
- `recovery_timeout`: 60 seconds before attempting recovery
- `success_threshold`: 2 successful calls to close the circuit
### Rate Limiting
Token bucket rate limiter prevents overwhelming RabbitMQ during burst scenarios:
- **Rate**: 500 messages per second
- **Burst**: 1000 messages maximum burst size
### Message Idempotency
The system prevents duplicate message sends from periodic Celery beat tasks:
1. **Content Hashing**: Message payloads are hashed (excluding timestamps)
2. **State Tracking**: Last-sent hash is cached per resource/message-type
3. **Skip Unchanged**: Messages with unchanged content are not re-sent
4. **Sequence Numbers**: Monotonically increasing numbers enable consumer-side ordering
### Message Delivery Configuration
STOMP messages include headers for reliable delivery:
- **Persistence**: Messages are persisted to disk (`persistent: true`)
- **TTL**: Type-based expiration (orders: 24h, resources: 2h, etc.)
- **Dead Letter Queue**: Failed messages routed to `waldur.dlq.messages`
- **Queue Limits**: Maximum 10,000 messages per queue with overflow rejection
### Celery Task Retry
The `publish_messages` task uses Celery's built-in retry mechanism:
```python
@shared_task(
autoretry_for=(ConnectionError, OSError, Exception),
retry_backoff=True, # Exponential backoff
retry_backoff_max=300, # Max 5 minutes between retries
max_retries=5,
retry_jitter=True, # Randomness to prevent thundering herd
)
def publish_messages(messages):
...
```
### Monitoring and Debug API
Staff-only endpoints under `/api/debug/pubsub/` provide system visibility:
| Endpoint | Method | Description |
|----------|--------|-------------|
| `/overview/` | GET | Dashboard with health status, issues, metrics summary |
| `/circuit_breaker/` | GET | Circuit breaker state, config, and history |
| `/circuit_breaker_reset/` | POST | Manually reset circuit breaker to CLOSED |
| `/metrics/` | GET | Publishing metrics (sent, failed, skipped, latency) |
| `/metrics_reset/` | POST | Reset all metrics counters |
| `/message_state_cache/` | GET | Idempotency cache statistics |
| `/queues/` | GET | Subscription queue overview with top queues |
| `/dead_letter_queue/` | GET | DLQ statistics across all vhosts |
#### Example: Check system health
```bash
curl -H "Authorization: Token " \
https://api.waldur.example/api/debug/pubsub/overview/
```
Response:
```json
{
"health_status": "healthy",
"issues": [],
"circuit_breaker": {
"state": "closed",
"healthy": true,
"failure_count": 0
},
"metrics": {
"messages_sent": 1523,
"messages_failed": 2,
"failure_rate": "0.1%",
"avg_latency_ms": 12.5
},
"last_updated": "2024-01-15T10:30:00Z"
}
```
### Health Status Indicators
The overview endpoint calculates health status:
- **healthy**: Circuit breaker closed and failure rate < 10%
- **degraded**: Circuit breaker open OR failure rate > 10%
- **critical**: Failure rate > 50%
### Existing RabbitMQ Monitoring Endpoints
Additional monitoring is available via:
- **GET /api/rabbitmq-stats/**: Queue statistics with message counts
- **POST /api/rabbitmq-stats/**: Purge or delete queues (staff only)
- **GET /api/rabbitmq-overview/**: Cluster health and throughput metrics
- **GET /api/rabbitmq-vhost-stats/**: Virtual host and subscription details
- **GET /api/rabbitmq-user-stats/**: Connection statistics per user

### Invitations
# Invitations
The invitation system in Waldur provides a mechanism for inviting users to join organizations (customers), projects, or other scoped resources with specific roles. The system supports two main invitation types: individual invitations and group invitations, with different workflows and approval mechanisms.
## Architecture Overview
The invitation system is built around three core models in `waldur_core.users.models`:
- **BaseInvitation**: Abstract base class providing common fields and functionality
- **Invitation**: Individual invitations for specific users with email-based delivery
- **GroupInvitation**: Template-based invitations that can be used by multiple users matching specific criteria
- **PermissionRequest**: Approval workflow for group invitation requests
## Invitation Types
### Individual Invitations
Individual invitations are sent to specific email addresses and provide a direct mechanism to grant users access to resources.
#### Key Features
- **Email-based delivery**: Invitations are sent to specific email addresses
- **Civil number validation**: Optional civil number matching for enhanced security
- **State management**: Full lifecycle tracking with states like pending, accepted, canceled, expired
- **Execution tracking**: Background processing with error handling and retry capabilities
- **Expiration handling**: Automatic expiration based on configurable timeouts
- **Webhook support**: External system integration for invitation delivery
#### State Flow
```mermaid
stateDiagram-v2
[*] --> PENDING: Create invitation
[*] --> REQUESTED: Staff approval required
[*] --> PENDING_PROJECT: Project not active yet
REQUESTED --> PENDING: Staff approves
REQUESTED --> REJECTED: Staff rejects
PENDING_PROJECT --> PENDING: Project becomes active
PENDING --> ACCEPTED: User accepts
PENDING --> CANCELED: Creator cancels
PENDING --> EXPIRED: Timeout reached
CANCELED --> PENDING: Resend invitation
EXPIRED --> PENDING: Resend invitation
ACCEPTED --> [*]
REJECTED --> [*]
```
### Group Invitations
Group invitations provide template-based access that multiple users can request to join, with an approval workflow. They support both private invitations (visible only to authenticated users with appropriate permissions) and public invitations (visible to all users including unauthenticated ones).
#### Key Features
- **Pattern-based matching**: Users can request access if they match email patterns or affiliations
- **Approval workflow**: Requests go through a review process before granting access
- **Auto-approval**: Optionally skip manual review for users matching invitation patterns
- **Project creation option**: Can automatically create projects instead of granting customer-level access
- **Role mapping**: Support for different roles at customer and project levels
- **Template-based naming**: Configurable project name templates for auto-created projects
- **Public visibility**: Public invitations can be viewed and requested by unauthenticated users
- **Duplicate role prevention**: Multiple layers of checks prevent duplicate role assignments
#### Workflow
```mermaid
sequenceDiagram
participant U as User
participant GI as GroupInvitation
participant PR as PermissionRequest
participant A as Approver
participant S as System
U->>GI: Submit request
GI->>GI: Check user already has role
GI->>GI: Check INVITATION_DISABLE_MULTIPLE_ROLES
GI->>GI: Check no existing PermissionRequest (pending/approved)
GI->>GI: Validate email/affiliation patterns
alt Validation fails
GI-->>U: 400 Bad Request
else Validation passes
GI->>PR: Create PermissionRequest
alt auto_approve enabled
PR->>PR: Auto-approve
PR->>S: Grant role (with duplicate guard)
PR-->>U: 200 OK (auto_approved: true)
else Manual approval
PR->>A: Notify approvers
A->>PR: Approve/Reject
alt Approved & auto_create_project
PR->>S: Create project (excludes soft-deleted)
S->>U: Grant project permission
else Approved & normal
PR->>S: Grant scope permission
end
PR->>U: Notify result
end
end
```
#### Public Group Invitations
Public group invitations are a special type of group invitation that can be viewed and requested by unauthenticated users. They are designed for open enrollment scenarios where organizations want to allow external users to request access to projects.
##### Key Characteristics
- **Unauthenticated visibility**: Listed in public API endpoints without authentication
- **Staff-only creation**: Only staff users can create and manage public invitations
- **Project-level access only**: Public invitations can only grant project-level roles, not customer-level roles
- **Automatic project creation**: All public invitations must use the auto-create project feature
- **Enhanced security**: Authentication is still required for submitting actual access requests
##### Constraints and Validation
1. **Staff authorization**: Only `is_staff=True` users can create public group invitations
2. **Auto-creation required**: Public invitations must have `auto_create_project=True`
3. **Project roles only**: Public invitations can only use roles starting with "PROJECT." (e.g., `PROJECT.MANAGER`, `PROJECT.ADMIN`)
4. **No customer-level access**: Cannot grant customer-level roles like `CUSTOMER.OWNER` or `CUSTOMER.SUPPORT`
##### Use Cases
- **Open research projects**: Universities allowing external researchers to request project access
- **Community initiatives**: Organizations providing project spaces for community members
- **Partner collaborations**: Companies offering project access to external partners
- **Educational platforms**: Schools providing project environments for students

### BaseInvitation (Abstract)
```python
class BaseInvitation:
created_by: ForeignKey[User] # Who created the invitation
customer: ForeignKey[Customer] # Associated customer (computed from scope)
role: ForeignKey[Role] # Role to be granted
scope: GenericForeignKey # Target scope (customer, project, etc.)
created: DateTimeField # Creation timestamp
uuid: UUIDField # Unique identifier
```
### Invitation
```python
class Invitation(BaseInvitation):
# State management
state: CharField # Current invitation state
execution_state: FSMField # Background processing state
# User identification
email: EmailField # Target email address
civil_number: CharField # Optional civil number for validation
# User details (copied from invitation)
full_name: CharField
native_name: CharField
phone_number: CharField
organization: CharField
job_title: CharField
# Processing
approved_by: ForeignKey[User] # Staff member who approved
error_message: TextField # Processing errors
extra_invitation_text: TextField # Custom message (max 250 chars)
```
### GroupInvitation
```python
class GroupInvitation(BaseInvitation):
is_active: BooleanField # Whether invitation is active
is_public: BooleanField # Allow unauthenticated users to see invitation
auto_approve: BooleanField # Auto-approve requests from matching users
# User pattern matching
user_email_patterns: JSONField # Email patterns for matching users
user_affiliations: JSONField # Affiliation patterns
user_identity_sources: JSONField # Allowed identity providers (e.g., eduGAIN, SAML)
# Project creation alternative
auto_create_project: BooleanField # Create project instead of customer role
project_role: ForeignKey[Role] # Role for auto-created project
project_name_template: CharField # Template for project naming
```
### PermissionRequest
```python
class PermissionRequest(ReviewMixin):
invitation: ForeignKey[GroupInvitation] # Associated group invitation
created_by: ForeignKey[User] # User requesting access
# Review workflow (inherited from ReviewMixin)
state: CharField # pending, approved, rejected
reviewed_by: ForeignKey[User]
reviewed_at: DateTimeField
review_comment: TextField
```
## Permission System Integration
### Access Control
Invitation management permissions are controlled through:
1. **Staff privileges**: Staff users can manage all invitations
2. **Scope-based permissions**: Users with CREATE permissions on scopes can manage invitations
3. **Customer-level access**: Customer owners can manage invitations for their resources
4. **Hierarchical permissions**: Customer permissions apply to contained projects
### Permission Checks
The system uses `can_manage_invitation_with()` utility (`src/waldur_core/users/utils.py:179`) for authorization:
```python
def can_manage_invitation_with(request, scope):
if request.user.is_staff:
return True
permission = get_create_permission(scope)
if has_permission(request, permission, scope):
return True
customer = get_customer(scope)
if has_permission(request, permission, customer):
return True
```
### Filtering and Visibility
- **InvitationFilterBackend**: Filters invitations based on user permissions
- **GroupInvitationFilterBackend**: Controls group invitation visibility, allows public invitations for unauthenticated users
- **PendingInvitationFilter**: Filters invitations user can accept
- **VisibleInvitationFilter**: Controls invitation detail visibility
## Duplicate Role Prevention
The invitation system enforces multiple layers of protection against granting duplicate roles.
These checks apply to both individual and group invitation flows.

## Update Order Processor: Comprehensive Capabilities
The `AbstractUpdateResourceProcessor` is the most complex processor, handling multiple types of resource updates. It provides a unified interface for various update operations while delegating specific logic to subclasses.
### Update Operation Types
The processor supports four primary update operation types:
#### 1. Resource Limit Updates
- **Detection**: `"old_limits"` present in `order.attributes`
- **Use Cases**:
- CPU/RAM quota adjustments
- Storage limit modifications
- Bandwidth allocation changes
- Service tier adjustments
- **Method**: `_process_renewal_or_limit_update(user, is_renewal=False)`
- **Validation**: Uses `validate_limits()` to ensure new limits are valid
#### 2. Prepaid Resource Renewals
- **Detection**: `order.attributes.get("action") == "renew"`
- **Use Cases**:
- Extending service end dates
- Renewing licenses or allocations
- Prepaid service extensions
- License renewals with optional limit changes
- **Method**: `_process_renewal_or_limit_update(user, is_renewal=True)`
- **Features**:
- Updates `end_date` and `end_date_requested_by`
- Maintains renewal history in resource attributes
- Supports combined renewal + limit changes
- Tracks renewal costs and dates
#### 3. Resource Options Updates
- **Detection**: `"new_options"` present in `order.attributes`
- **Use Cases**:
- Configuration parameter changes
- Feature toggles
- Service option modifications
- Metadata updates
- **Method**: `_process_options_update(user)`
- **Features**:
- Merges new options with existing options
- Immediate synchronous processing
- Automatic success/failure handling
#### 4. Plan Switches
- **Detection**: Default case when no other patterns match
- **Use Cases**:
- Service tier changes (Basic → Premium)
- Billing model switches
- Feature set modifications
- Service level adjustments
- **Method**: `_process_plan_switch(user)`
- **Features**:
- Changes resource plan association
- Supports both synchronous and asynchronous processing
- Triggers appropriate billing recalculations
### Update Processing Flow
```mermaid
flowchart TD
A[AbstractUpdateResourceProcessor.process_order] --> B{Check Order Type}
B -->|action == 'renew'| C[Renewal Processing]
B -->|'old_limits' exists| D[Limit Update Processing]
B -->|'new_options' exists| E[Options Update Processing]
B -->|Default| F[Plan Switch Processing]
C --> G[_process_renewal_or_limit_update",
"has_conflicts": true,
"conflict_details": "I have consulting relationships with..."
}
```
These forms track general financial interests and relationships with `valid_until` expiry.
### Proposal-Specific Conflicts at Invitation Acceptance
When accepting a reviewer invitation, reviewers can optionally declare conflicts with specific proposals. This creates `ConflictOfInterest` records (not disclosure forms):
```http
POST /api/reviewer-invitations/{token}/accept/
{
"declared_conflicts": [
{
"proposal_uuid": "",
"coi_type": "COAUTH_RECENT",
"description": "I co-authored a paper with the PI in 2024"
}
]
}
```
**Key differences from periodic disclosures:**
| Aspect | COIDisclosureForm | ConflictOfInterest (self-disclosed) |
|--------|-------------------|-------------------------------------|
| Scope | General/call-level | Specific proposal |
| Timing | Periodic/annual | At invitation acceptance |
| Fields | `valid_until`, `is_current` | `proposal`, `coi_type`, `severity` |
| Detection method | N/A | `self_disclosed` |
**Self-declared conflict workflow:**
1. Reviewer receives invitation with proposal list
2. Reviews proposals (based on `invitation_proposal_disclosure` setting)
3. Optionally declares conflicts with specific proposals
4. Accepts invitation (NOT blocked by declared conflicts)
5. Manager reviews self-declared conflicts via normal COI management
## Best Practices
1. **Run detection early**: Trigger COI detection as soon as the reviewer pool is finalized
2. **Review pending conflicts**: Don't leave conflicts in pending status
3. **Document waivers**: Always provide management plans for waived conflicts
4. **Update reviewer profiles**: Ensure reviewer publications and affiliations are current
5. **Configure appropriately**: Adjust lookback periods based on field norms

### Call Eligibility and Applicant Attribute Configuration
# Call Eligibility and Applicant Attribute Configuration
Waldur's proposal module supports AAI-based eligibility restrictions and GDPR-compliant applicant attribute exposure configuration. This enables call managers to control who can submit proposals and what applicant data is visible during the review process.
## Call Eligibility Restrictions
Calls for proposals can define eligibility restrictions based on user attributes sourced from identity providers (IdPs). This ensures only qualified applicants from specific institutions, countries, or assurance levels can submit proposals.
### Architecture Overview
```mermaid
flowchart TD
subgraph "User Profile (from IdP)"
U[User]
U --> N[nationality/nationalities]
U --> O[organization_type]
U --> A[eduperson_assurance]
U --> E[email]
U --> AF[affiliations]
U --> IS[identity_source]
end
subgraph "Call Restrictions"
C[Call]
C --> RN[user_nationalities]
C --> RO[user_organization_types]
C --> RA[user_assurance_levels]
C --> RE[user_email_patterns]
C --> RAF[user_affiliations]
C --> RIS[user_identity_sources]
end
subgraph "Eligibility Check"
EC{Validate}
EC -->|Pass| ALLOW[Allow Submission]
EC -->|Fail| DENY[Deny with Restrictions]
end
U --> EC
C --> EC
```
### Restriction Fields
| Field | Type | Logic | Description |
|-------|------|-------|-------------|
| `user_nationalities` | JSON array | OR | User must have at least one matching nationality (ISO 3166-1 alpha-2) |
| `user_organization_types` | JSON array | OR | User's organization type must match one (SCHAC URN) |
| `user_assurance_levels` | JSON array | AND | User must have ALL specified assurance levels (REFEDS) |
| `user_email_patterns` | JSON array | OR | User's email must match at least one regex pattern |
| `user_affiliations` | JSON array | OR | User must have at least one matching affiliation |
| `user_identity_sources` | JSON array | OR | User must authenticate via one of the specified IdPs |
### Restriction Logic
- **Basic restrictions** (email patterns, affiliations, identity sources) use OR logic
- **AAI restrictions** (nationalities, organization types) use OR logic
- **Assurance levels** use AND logic - user must have ALL required levels
- All configured restriction categories must pass (AND between categories)
### API Endpoints
#### Check Eligibility
Check if the current user can submit to a call:
```http
GET /api/proposal-public-calls/{uuid}/check_eligibility/
Authorization: Bearer {token}
```
**Response (eligible):**
```json
{
"is_eligible": true,
"restrictions": []
}
```
**Response (not eligible):**
```json
{
"is_eligible": false,
"restrictions": [
"User nationality 'DE' is not in allowed list: ['FI', 'SE', 'NO']",
"User does not have required assurance level: https://refeds.org/assurance/IAP/high"
]
}
```
#### Configure Restrictions
Call managers can configure restrictions when creating or updating a call:
```http
PATCH /api/proposal-calls/{uuid}/
Content-Type: application/json
Authorization: Bearer {token}
{
"user_nationalities": ["FI", "SE", "NO", "DK", "IS"],
"user_organization_types": ["urn:schac:homeOrganizationType:int:university"],
"user_assurance_levels": ["https://refeds.org/assurance/IAP/medium"],
"user_email_patterns": [],
"user_affiliations": [],
"user_identity_sources": []
}
```
### Examples
#### Nordic Universities Only
```json
{
"user_nationalities": ["FI", "SE", "NO", "DK", "IS"],
"user_organization_types": [
"urn:schac:homeOrganizationType:int:university",
"urn:schac:homeOrganizationType:int:research-institution"
]
}
```
#### High Assurance Required
```json
{
"user_assurance_levels": [
"https://refeds.org/assurance/IAP/high",
"https://refeds.org/assurance/ID/eppn-unique-no-reassign"
]
}
```
#### Specific Federation Members
```json
{
"user_identity_sources": ["haka", "swamid", "feide"],
"user_email_patterns": [".*@(helsinki\\.fi|kth\\.se|uio\\.no)$"]
}
```
## Applicant Attribute Exposure Configuration
The `CallApplicantAttributeConfig` model controls which applicant attributes are visible to call managers and reviewers. This supports GDPR compliance and anonymous review workflows.
### Overview
```mermaid
flowchart LR
subgraph "Applicant Profile"
AP[Applicant User]
AP --> |has| A1[full_name]
AP --> |has| A2[email]
AP --> |has| A3[organization]

```
### Configuration Fields
| Field | Default | Description |
|-------|---------|-------------|
| `expose_full_name` | true | Show applicant's full name |
| `expose_email` | true | Show applicant's email address |
| `expose_organization` | true | Show applicant's organization |
| `expose_affiliations` | false | Show applicant's affiliations list |
| `expose_organization_type` | false | Show organization type (SCHAC URN) |
| `expose_organization_country` | false | Show organization's country |
| `expose_nationality` | false | Show primary nationality |
| `expose_nationalities` | false | Show all nationalities |
| `expose_country_of_residence` | false | Show country of residence |
| `expose_eduperson_assurance` | false | Show assurance levels |
| `expose_identity_source` | false | Show identity provider |
| `reviewers_see_applicant_details` | false | If false, proposals are anonymized for reviewers |
### API Endpoints
#### Get Attribute Configuration
```http
GET /api/proposal-calls/{uuid}/applicant_attribute_config/
Authorization: Bearer {token}
```
**Response (custom config):**
```json
{
"uuid": "abc123...",
"call_uuid": "def456...",
"call_name": "Nordic HPC Call 2025",
"expose_full_name": true,
"expose_email": true,

"expose_eduperson_assurance": false,
"expose_identity_source": false,
"reviewers_see_applicant_details": false,
"exposed_fields": ["full_name", "email", "organization", "nationality"]
}
```
**Response (no config - defaults):**
```json
{
"is_default": true,
"exposed_fields": ["full_name", "email", "organization"]
}
```
#### Create/Update Configuration
```http
POST /api/proposal-calls/{uuid}/update_applicant_attribute_config/
Content-Type: application/json
Authorization: Bearer {token}
{
"expose_full_name": true,
"expose_email": true,
"expose_organization": true,
"expose_nationality": true,
"expose_organization_country": true,
"reviewers_see_applicant_details": false
}
```
#### Delete Configuration (Revert to Defaults)
```http
DELETE /api/proposal-calls/{uuid}/delete_applicant_attribute_config/
Authorization: Bearer {token}
```
Returns `204 No Content` on success.
### Permissions
All attribute configuration endpoints require `UPDATE_CALL` permission on the call.
## Use Cases
### Anonymous Peer Review
For double-blind review processes:
```json
{
"expose_full_name": false,
"expose_email": false,
"expose_organization": false,
"reviewers_see_applicant_details": false
}
```
Call managers still see full applicant details, but reviewers see anonymized proposals.
### Nationality-Based Eligibility Tracking
For calls requiring nationality verification:
```json
{
"expose_nationality": true,
"expose_nationalities": true,
"expose_country_of_residence": true
}
```
Combined with eligibility restrictions:
```json
{
"user_nationalities": ["FI", "SE", "NO"]
}
```
### High-Trust Research Calls
For calls requiring strong identity assurance:
```json
{
"user_assurance_levels": [
"https://refeds.org/assurance/IAP/high"
]
}
```
With attribute exposure for verification:
```json
{
"expose_eduperson_assurance": true,
"expose_identity_source": true
}
```
## Integration with User Profile Attributes
The eligibility and attribute exposure features build on Waldur's extended user profile attributes. See [User Profile Attributes](../user-profile-attributes.md) for details on:
- AAI attribute sources (OIDC claims)
- ISO and SCHAC standards
- REFEDS assurance profiles

### Reviewer-Proposal Matching System
# Reviewer-Proposal Matching System
The Waldur proposal module includes an automated reviewer-proposal matching system that computes expertise affinity scores and generates optimal reviewer assignments. This ensures qualified reviewers are matched with proposals in their area of expertise.

## Affinity Scoring Methods
The system computes affinity scores between reviewers and proposals using configurable methods.
### Keyword-Based Scoring
Matches reviewer expertise keywords against proposal text content.
**How it works:**
1. Extracts reviewer's expertise keywords with proficiency weights
2. Searches proposal text (title, summary, description) for keyword matches
3. Calculates weighted match score
**Proficiency weights:**
| Proficiency Level | Weight |
|-------------------|--------|
| Expert | 1.0 |
| Familiar | 0.7 |
| Basic | 0.3 |
```python
# Example: Keyword affinity computation
reviewer_keywords = {
"machine learning": 1.0, # Expert
"neural networks": 0.7, # Familiar
"data science": 0.3 # Basic
}
proposal_text = "Machine learning approaches for neural network optimization..."
# Matches: "machine learning" (1.0), "neural networks" (0.7)
# Score: (1.0 + 0.7) / (1.0 + 0.7 + 0.3) = 0.85
```
### TF-IDF Text Similarity
Computes semantic similarity between reviewer expertise and proposal content using Term Frequency-Inverse Document Frequency (TF-IDF) vectors.
**Reviewer text sources:**
- Expertise keywords (weighted by proficiency)
- Recent publication titles and abstracts (last 5 years)
- Biography text
**Proposal text sources:**
- Proposal name/title
- Project summary
- Project description
**Algorithm:**
1. Tokenize text (lowercase, remove stopwords)
2. Compute TF-IDF vectors for reviewer and proposal
3. Calculate cosine similarity between vectors
```python
# TF-IDF similarity example
reviewer_vector = {"machine": 0.3, "learning": 0.4, "neural": 0.2, ...}
proposal_vector = {"machine": 0.5, "learning": 0.3, "optimization": 0.4, ...}
# Cosine similarity = dot_product / (magnitude1 * magnitude2)
similarity = 0.72
```
### Combined Method
Default method that combines keyword and text-based scoring with configurable weights.
```python
affinity_score = (keyword_weight × keyword_score) + (text_weight × text_score)
# Default weights
keyword_weight = 0.4
text_weight = 0.6
```
## Matching Configuration
Each call can have its own matching configuration via `MatchingConfiguration`:
| Field | Type | Default | Description |
|-------|------|---------|-------------|
| `affinity_method` | choice | `combined` | Scoring method: `keyword`, `tfidf`, or `combined` |
| `keyword_weight` | float | 0.4 | Weight for keyword scoring (0-1) |
| `text_weight` | float | 0.6 | Weight for TF-IDF scoring (0-1) |
| `min_reviewers_per_proposal` | int | 3 | Minimum reviewers per proposal |
| `max_reviewers_per_proposal` | int | 5 | Maximum reviewers per proposal |
| `min_proposals_per_reviewer` | int | 3 | Minimum proposals per reviewer |
| `max_proposals_per_reviewer` | int | 10 | Maximum proposals per reviewer |
| `algorithm` | choice | `minmax` | Assignment algorithm |
| `min_affinity_threshold` | float | 0.1 | Minimum affinity for suggestions |
| `use_reviewer_bids` | bool | true | Consider reviewer preferences |
| `bid_weight` | float | 0.3 | Weight for reviewer bids |
**Validation:** `keyword_weight + text_weight` must equal 1.0
## Assignment Algorithms
Three algorithms are available for computing optimal reviewer-proposal assignments:
### MinMax (Balanced Load)
Balances reviewer workload while maximizing total affinity.
**Characteristics:**
- Prioritizes even distribution of reviews
- Good for calls with many proposals and limited reviewers
- Prevents reviewer overload
### FairFlow (Quality Threshold)
Ensures minimum quality threshold for all assignments.
**Characteristics:**
- Only assigns pairs above `min_affinity_threshold`
- Better match quality at cost of some assignments
- Useful for specialized domains
### Hungarian (Global Optimum)
Finds globally optimal assignment maximizing total affinity.
**Characteristics:**
- Optimal solution for the assignment problem
- May result in uneven workload distribution
- Best for small to medium-sized calls
## Reviewer Bids
Reviewers can express preferences for reviewing specific proposals:
| Bid Value | Weight | Description |
|-----------|--------|-------------|
| `eager` | +1.0 | Reviewer wants to review this proposal |
| `willing` | +0.5 | Reviewer is willing to review |
| `not_willing` | -0.5 | Reviewer prefers not to review |
| `conflict` | -1.0 | Reviewer has conflict of interest |
When `use_reviewer_bids` is enabled, bid weights are incorporated into the final affinity score:
```python
final_score = affinity_score + (bid_weight × bid_value)
```
## Reviewer Discovery Workflow
The system supports two paths for finding reviewers:
### Path A: Algorithm-Based Discovery
For reviewers with published profiles:
```text
1. Reviewer publishes profile
├── POST /api/reviewer-profiles/me/publish/
└── Sets is_published=true, available_for_reviews=true
2. Manager triggers suggestion generation
└── POST /api/proposal-protected-calls/{uuid}/generate-suggestions/
3. Algorithm evaluates all published profiles
├── Excludes reviewers already in pool
├── Excludes reviewers already suggested
└── Creates ReviewerSuggestion records with affinity scores
4. Manager reviews suggestions
├── Confirm: POST /api/reviewer-suggestions/{uuid}/confirm/
└── Reject: POST /api/reviewer-suggestions/{uuid}/reject/ (with reason)
5. Manager sends invitations to confirmed suggestions
└── POST /api/proposal-protected-calls/{uuid}/send-invitations/
6. Reviewer views invitation details
├── GET /api/reviewer-invitations/{token}/
└── Returns: call info, COI config, proposals (based on disclosure level)
7. Reviewer accepts/declines with optional COI disclosure
├── POST /api/reviewer-invitations/{token}/accept/
│ └── Can include declared_conflicts for specific proposals
└── POST /api/reviewer-invitations/{token}/decline/
```
### Path B: Direct Email Invitation
For reviewers without existing profiles:
```text
1. Manager invites by email
└── POST /api/proposal-protected-calls/{uuid}/invite-by-email/
2. Invitation sent to email address
└── CallReviewerPool created (reviewer=null, invited_email set)
3. Invited person clicks invitation link
├── GET /api/reviewer-invitations/{token}/
└── Response indicates profile_status: "missing" or "unpublished"
4. Invited person creates and publishes profile
├── POST /api/reviewer-profiles/ (create)
└── POST /api/reviewer-profiles/me/publish/ (publish)
5. Accept invitation with optional COI disclosure
├── POST /api/reviewer-invitations/{token}/accept/
└── Profile automatically linked to CallReviewerPool
```
### Reviewer Profile Visibility
Reviewer profiles have visibility controls:
| Field | Default | Description |
|-------|---------|-------------|
| `is_published` | false | Profile discoverable by algorithm |
| `available_for_reviews` | true | Currently accepting review requests |
| `published_at` | null | When profile was published |
**Visibility rules:**
- **Own profile**: Always visible to the profile owner
- **Pool members**: Managers see ACCEPTED pool members only
- **Suggestions**: Managers see full profile in suggestion list
- **Discovery**: Algorithm only considers published + available profiles
## Suggestion Status Workflow

| `bid` | choice | eager/willing/not_willing/conflict |
| `comment` | text | Optional explanation |
## Integration with COI Detection
The matching system integrates with [Conflict of Interest Detection](proposals-coi.md):
1. Before computing suggestions, COI status is checked
2. Reviewers with confirmed COIs are excluded from matching
3. Self-disclosed conflicts (via bids) affect affinity scores
4. Waived conflicts may still be assigned with oversight
```text
┌──────────────────────────────────────────────────────────────────────────┐

└──────────────────────────────────────────────────────────────────────────┘
```
## Performance Considerations
### Affinity Computation
- Computation is O(reviewers × proposals)
- Results cached in `ReviewerProposalAffinity` table
- Recompute when profiles or proposals change significantly
### Corpus IDF
- TF-IDF uses corpus-wide IDF for better term weighting
- Corpus includes all reviewer texts and proposal texts
- Computed once per call, reused for all pairs
### Large Calls
- For calls with 100+ proposals and 50+ reviewers:
- Use batch processing
- Consider incremental updates
- Monitor computation time

### Waldur Proposal Module
# Waldur Proposal Module
The Waldur proposal module provides a comprehensive research proposal management system that enables institutions to manage competitive resource allocation through structured calls for proposals, peer review processes, and automated resource provisioning.
## Architecture Overview
The proposal system follows a **Call → Round → Proposal → Review → Allocation** architecture that handles the complete lifecycle from call publication to resource delivery:
```mermaid
graph TB
subgraph "Call Management"
CMO[CallManagingOrganisation] --> C[Call]
C --> RO[RequestedOffering]
C --> CRT[CallResourceTemplate]
CD[CallDocument] --> C
end
subgraph "Submission Process"
C --> R[Round]
R --> P[Proposal]
P --> RR[RequestedResource]
P --> PD[ProposalDocumentation]
P --> MP[Waldur Project]
end
subgraph "Review System"
P --> REV[Review]
REV --> RC[ReviewComment]
U[User/Reviewer] --> REV
end
subgraph "Resource Allocation"
P --> RA[ResourceAllocator]
RR --> MR[Marketplace Resource]
RA --> MR
PPRM[ProposalProjectRoleMapping] --> MP
end
```
### Core Models
- **`CallManagingOrganisation`**: Organizations that create and manage calls for proposals
- **`Call`**: Main entity representing calls with configuration for review settings and duration
- **`Round`**: Time-bounded submission periods with configurable review and allocation strategies
- **`Proposal`**: Individual proposals with project details and resource requests
- **`RequestedResource`**: Specific resource requests within proposals linked to marketplace
- **`Review`**: Peer review system with scoring, comments, and field-specific feedback
## Call Lifecycle and State Management
### Call States
Calls progress through a simple but effective state machine:
```mermaid
stateDiagram-v2
[*] --> DRAFT : Call created
DRAFT --> ACTIVE : Call published
DRAFT --> ARCHIVED : Call canceled
ACTIVE --> ARCHIVED : Call completed
ARCHIVED --> [*]
```
#### Call State Descriptions
| State | Description | Operations Allowed |
|-------|-------------|-------------------|
| **DRAFT** | Call being prepared by organization | Edit call details, add rounds, configure offerings |
| **ACTIVE** | Call open for submissions | Submit proposals, manage reviews, allocate resources |
| **ARCHIVED** | Call completed or canceled | View historical data, generate reports |
### Proposal States
Proposals follow a comprehensive lifecycle with review integration:
```mermaid
stateDiagram-v2
[*] --> DRAFT : Proposal created
DRAFT --> SUBMITTED : Submitter ready
DRAFT --> CANCELED : Submitter cancels
SUBMITTED --> IN_REVIEW : Review process starts
SUBMITTED --> CANCELED : Admin cancels
IN_REVIEW --> ACCEPTED : Positive review outcome
IN_REVIEW --> REJECTED : Negative review outcome
IN_REVIEW --> CANCELED : Process canceled
ACCEPTED --> [*] : Resources allocated
REJECTED --> [*] : Process complete
CANCELED --> [*] : Process terminated
```
#### Proposal State Descriptions
| State | Description | Triggers | Actions Available |
|-------|-------------|----------|-------------------|
| **DRAFT** | Proposal being prepared | User creation | Edit, add resources, upload docs |
| **SUBMITTED** | Proposal submitted for review | User submission | View, withdraw |
| **IN_REVIEW** | Under review by experts | System/admin trigger | Review, comment, score |
| **ACCEPTED** | Approved for resource allocation | Review completion | Allocate resources, create project |
| **REJECTED** | Declined after review | Review completion | View feedback, appeal |
| **CANCELED** | Withdrawn or administratively canceled | User/admin action | Archive |
### Review States
Reviews maintain independent state for tracking progress:
```mermaid
stateDiagram-v2
[*] --> IN_REVIEW : Review assigned
IN_REVIEW --> SUBMITTED : Review completed
IN_REVIEW --> REJECTED : Reviewer withdraws/declines
SUBMITTED --> [*] : Review processed
REJECTED --> [*] : Assignment ended
```
## Round Management and Strategies
### Review Strategies
Rounds can be configured with different review timing approaches:
| Strategy | Description | Use Case | Workflow |
|----------|-------------|----------|----------|
| **AFTER_ROUND** | Reviews start after submission deadline | Large competitive calls | All proposals collected → batch review assignment |
| **AFTER_PROPOSAL** | Reviews start immediately upon submission | Rolling submissions | Individual proposal → immediate review assignment |
### Allocation Strategies
Resource allocation can be automated or manual:
| Strategy | Description | Decision Maker | Allocation Logic |
|----------|-------------|---------------|------------------|
| **BY_CALL_MANAGER** | Manual allocation by call administrators | Human reviewers | Call manager reviews scores and allocates |
| **AUTOMATIC** | Automated based on review scores | System algorithm | Automatic allocation above score threshold |
### Round Configuration
```mermaid
graph LR
subgraph "Round Configuration"
ST[Start Time] --> CT[Cutoff Time]
CT --> RD[Review Duration]
RD --> MR[Min Reviewers]
MR --> MS[Min Score]
MS --> AD[Allocation Date]
end
subgraph "Strategies"
RS[Review Strategy:
);
};
```
### 6. Frontend: Create User-Facing Component
Create the component that users see in order forms:
**File**: `src/marketplace/common/YourCustomField.tsx`
```typescript
import { useState, useEffect, useCallback, useRef } from 'react';
import { FormField } from '@waldur/form/types';
import { translate } from '@waldur/i18n';
interface YourCustomFieldProps extends FormField {
field: {
your_custom_config?: {
custom_param?: string;
// ... other config fields
};
label?: string;
help_text?: string;
};
}
export const YourCustomField = ({
field,
input,
tooltip,
}: YourCustomFieldProps) => {
const fieldValue = input?.value || '';
const [localValue, setLocalValue] = useState(fieldValue);
const inputRef = useRef(input);
inputRef.current = input;
// Sync external changes to local state
useEffect(() => {
setLocalValue(fieldValue);
}, [fieldValue]);
// Handle user input
const handleChange = useCallback((newValue: string) => {
setLocalValue(newValue);
if (inputRef.current?.onChange) {
inputRef.current.onChange(newValue);
}
}, []);
return (
{tooltip &&
{tooltip}
}
{/* Implement your custom UI here */}
handleChange(e.target.value)}
placeholder={translate('Enter value')}
/>
> = StringField;
let params: Record = {};
switch (option.type) {
// ... existing cases ...
case 'your_custom_type':
OptionField = YourCustomField;
params = {
field: option,
};
break;
}
return { OptionField, params };
};
```
### 9. Frontend: Handle Form Data Processing
Update form utilities if needed:
**File**: `src/marketplace/offerings/store/utils.ts`
```typescript
export const formatOption = (option: OptionFormData) => {
const { type, choices, your_custom_config, ...rest } = option;
const item: OptionField = {
type: type.value as OptionFieldTypeEnum,
...rest,
};
// Handle your custom configuration
if (your_custom_config && item.type === 'your_custom_type') {
item.your_custom_config = your_custom_config;
}
return item;
};
```
**File**: `src/marketplace/details/utils.ts`
```typescript
const formatAttributes = (props): OrderCreateRequest['attributes'] => {
// ... existing logic ...
for (const [key, value] of Object.entries(attributes)) {
const optionConfig = props.offering.options?.options?.[key];
if (optionConfig?.type === 'your_custom_type') {
// Handle your custom type's data format
newAttributes[key] = value; // Keep as-is or transform as needed
} else if (optionConfig?.type === 'conditional_cascade') {
newAttributes[key] = value; // Existing cascade handling
} else if (typeof value === 'object' && !Array.isArray(value)) {
newAttributes[key] = value['value']; // Regular select handling
} else {
newAttributes[key] = value;
}
}
return newAttributes;
};
```
### 10. Testing
Create comprehensive tests for your new option type:
**File**: `src/waldur_mastermind/marketplace/tests/test_your_custom_type.py`
```python
from rest_framework import test
from waldur_mastermind.marketplace import serializers
from waldur_mastermind.common.serializers import validate_options
class YourCustomTypeTest(test.APITestCase):
def test_valid_configuration(self):
"""Test that valid configurations are accepted"""
option_data = {
"type": "your_custom_type",
"label": "Custom Field",
"your_custom_config": {
"custom_param": "value"
},
}
serializer = serializers.OptionFieldSerializer(data=option_data)
self.assertTrue(serializer.is_valid(), serializer.errors)
def test_order_validation(self):
"""Test that order attributes are validated correctly"""
options = {
'custom_field': {
'type': 'your_custom_type',
'label': 'Custom Field',
'required': True,
}
}
attributes = {
'custom_field': 'valid_value' # Or whatever format your type expects
}
try:
validate_options(options, attributes)
except Exception as e:
self.fail(f"validate_options should accept your_custom_type: {e}")
```
## Key Considerations
### Data Format Consistency
- **Configuration Phase**: How admins configure the option (JSON strings for complex data)
- **Display Phase**: How the option is displayed in forms (parsed objects)
- **Submission Phase**: What format users submit (depends on your UI component)
- **Storage Phase**: How the data is stored in orders/resources (final format)
### Error Handling
- Ensure all error dictionaries use string keys for JSON serialization compatibility
- Provide clear, actionable error messages
- Handle edge cases (empty values, malformed data, etc.)
### Form Integration
- **Redux-form compatibility**: For admin configuration interfaces
- **React-final-form compatibility**: For some user interfaces (when `finalForm=true`)
- **FormContainer integration**: For most user order forms
### Performance
- Use `useCallback` and `useRef` to prevent unnecessary re-renders
- Avoid object dependencies in `useEffect` that cause infinite loops
- Memoize expensive computations
## Example: Conditional Cascade Implementation
The `conditional_cascade` type demonstrates all these concepts:
### Backend Components
- `CascadeStepSerializer` - Validates individual steps with JSON parsing
- `CascadeConfigSerializer` - Validates overall configuration with dependency checking
- `ConditionalCascadeField` (in common/serializers.py) - Handles order validation
### Frontend Components
- `ConditionalCascadeConfiguration` - Admin configuration interface (redux-form)
- `ConditionalCascadeWidget` - Admin form component (redux-form)
- `ConditionalCascadeField` - User order form component (FormContainer/redux-form)
### Key Features
- **Cascading Dependencies**: Dropdowns that depend on previous selections
- **JSON Configuration**: Complex configuration stored as JSON strings
- **Object Preservation**: Keeps selection objects intact through form processing
- **Bidirectional Sync**: Proper state management between form and component
## Testing Strategy
Create tests covering:
1. **Configuration Validation** - Valid/invalid option configurations
2. **Order Processing** - Attribute validation during order creation
3. **Edge Cases** - Unicode, special characters, empty values, malformed data
4. **Error Handling** - JSON serialization compatibility, clear error messages
5. **Integration** - Mixed field types, form submission end-to-end
## Best Practices
1. **Follow Existing Patterns** - Study similar option types before implementing
2. **Incremental Development** - Implement backend validation first, then frontend
3. **Comprehensive Testing** - Test all data paths and edge cases
4. **Error Prevention** - Use TypeScript interfaces and runtime validation
5. **Documentation** - Document configuration format and usage examples
## Common Pitfalls
1. **JSON Serialization Errors** - Always use string keys in error dictionaries
2. **Infinite Re-renders** - Avoid objects in useEffect dependencies
3. **Form Integration Issues** - Ensure proper `input` prop handling
4. **Data Format Mismatches** - Handle format differences between config/display/submission
5. **Validation Bypass** - Don't forget to add your type to `FIELD_CLASSES` mapping
### Update Frontend Type Handlers
Add your new type to the `OptionValueRenders` object in the frontend:
**File**: `src/marketplace/resources/options/OptionValue.tsx`
```typescript
const OptionValueRenders: Record ReactNode> = {
// ... existing handlers ...
your_custom_type: (value) => value, // Add appropriate renderer
};
```
**Important**: If this step is missed, TypeScript compilation will fail with:
```text
Property 'your_custom_type' is missing in type {...} but required in type 'Record ReactNode>'
```
Following this guide ensures your custom option type integrates seamlessly with Waldur's marketplace system and provides a consistent user experience.
## Built-in Option Types
### Component Multiplier
The `component_multiplier` option type allows users to input a value that gets automatically multiplied by a configurable factor to set limits for limit-based offering components.
#### Use Case
Perfect for scenarios where users need to specify resources in user-friendly units that need conversion:
- **Storage**: User enters "2 TB", automatically sets 100,000 inodes (2 × 50,000)
- **Compute**: User enters "4 cores", automatically sets 16 GB RAM (4 × 4)
- **Network**: User enters "100 Mbps", automatically sets bandwidth limits in bytes
#### Configuration
**Backend Configuration** (`component_multiplier_config`):
```json
{
"component_type": "storage_inodes",
"factor": 50000,
"min_limit": 1,
"max_limit": 100
}
```
**Option Definition**:
```json
{
"storage_size": {
"type": "component_multiplier",
"label": "Storage Size (TB)",
"help_text": "Enter storage size in terabytes",
"required": true,
"component_multiplier_config": {
"component_type": "storage_inodes",
"factor": 50000,
"min_limit": 1,
"max_limit": 100
}
}
}
```
#### Behavior
1. **User Input**: User enters a value (e.g., "2" for 2 TB)
2. **Frontend Multiplication**: Value is multiplied by factor (2 × 50,000 = 100,000)
3. **Automatic Limit Setting**: The calculated value (100,000) is automatically set as the limit for the specified component (`storage_inodes`)
4. **Validation**: Frontend validates user input against `min_limit` and `max_limit` before multiplication
#### Requirements
- **Component Dependency**: Must reference an existing limit-based component (`billing_type: "limit"`)
- **Factor**: Must be a positive integer ≥ 1
- **Limits**: `min_limit` and `max_limit` apply to user input, not the calculated result
#### Implementation Components
- **Configuration**: `ComponentMultiplierConfiguration.tsx` - Admin interface for setting up the multiplier
- **User Field**: `ComponentMultiplierField.tsx` - User input field that handles multiplication and limit updates

### Marketplace SLURM Partitions and Software Catalogs
# Marketplace SLURM Partitions and Software Catalogs
This guide covers SLURM partition configuration and their integration with software catalogs in Waldur's marketplace.
## Overview
SLURM partitions represent compute partitions in a cluster that can be associated with marketplace offerings. They define resource limits, scheduling policies, access controls, and optionally link to software catalogs for partition-specific software availability.
## SLURM Partition Model
The OfferingPartition model maps closely to SLURM's partition_info_t struct and includes comprehensive configuration options for HPC environments.
### Partition Parameters
#### Architecture
- `cpu_arch`: CPU architecture of the partition (e.g., `x86_64/amd/zen3`)
- `gpu_arch`: GPU architecture of the partition (e.g., `nvidia/cc90`, `amd/gfx90a`)
#### CPU Configuration
- `cpu_bind`: Default task binding policy (SLURM cpu_bind)
- `def_cpu_per_gpu`: Default CPUs allocated per GPU
- `max_cpus_per_node`: Maximum allocated CPUs per node
- `max_cpus_per_socket`: Maximum allocated CPUs per socket
#### Memory Configuration (in MB)
- `def_mem_per_cpu`: Default memory per CPU
- `def_mem_per_gpu`: Default memory per GPU
- `def_mem_per_node`: Default memory per node
- `max_mem_per_cpu`: Maximum memory per CPU
- `max_mem_per_node`: Maximum memory per node
#### Time Limits
- `default_time`: Default time limit in minutes
- `max_time`: Maximum time limit in minutes
- `grace_time`: Preemption grace time in seconds
#### Node Configuration
- `max_nodes`: Maximum nodes per job
- `min_nodes`: Minimum nodes per job
- `exclusive_topo`: Exclusive topology access required
- `exclusive_user`: Exclusive user access required
#### Scheduling Configuration
- `priority_tier`: Priority tier for scheduling and preemption
- `qos`: Quality of Service (QOS) name
- `req_resv`: Require reservation for job allocation
## Partition Management API
### Available Endpoints
Partition management is handled through offering actions, similar to software catalog management:
- `add_partition`: Add a new partition to an offering
- `update_partition`: Update partition configuration
- `remove_partition`: Remove a partition from an offering
### Add Partition to Offering
```bash
# Add partition to offering
curl -X POST "https://your-waldur.example.com/api/marketplace-provider-offerings/{offering_uuid}/add_partition/" \
-H "Authorization: Token your-token" \
-H "Content-Type: application/json" \
-d '{
"partition_name": "gpu-partition",
"cpu_arch": "x86_64/amd/zen3",
"gpu_arch": "nvidia/cc90",
"max_cpus_per_node": 64,
"max_mem_per_node": 512000,
"max_time": 2880,
"default_time": 60,
"qos": "gpu",
"priority_tier": 1
}'
```
### Update Partition Configuration
```bash
# Update partition configuration
curl -X PATCH "https://your-waldur.example.com/api/marketplace-provider-offerings/{offering_uuid}/update_partition/" \
-H "Authorization: Token your-token" \
-H "Content-Type: application/json" \

"partition_uuid": "partition-uuid",
"max_time": 4320,
"priority_tier": 2
}'
```
### Remove Partition from Offering
```bash
# Remove partition from offering
curl -X POST "https://your-waldur.example.com/api/marketplace-provider-offerings/{offering_uuid}/remove_partition/" \
-H "Authorization: Token your-token" \
-H "Content-Type: application/json" \
-d '{
"partition_uuid": "partition-uuid"
}'
```
## Partition Software Catalog Associations
Software catalogs can be optionally associated with specific partitions through the `partition` field in OfferingSoftwareCatalog. This enables partition-specific software availability, allowing different partitions to expose different software sets.
### Associating Software Catalogs with Partitions
```bash
# Add software catalog to specific partition
curl -X POST "https://your-waldur.example.com/api/marketplace-provider-offerings/{offering_uuid}/add_software_catalog/" \
-H "Authorization: Token your-token" \
-H "Content-Type: application/json" \
-d '{
"catalog": "catalog-uuid",
"enabled_cpu_family": ["x86_64"],
"enabled_cpu_microarchitectures": ["generic"],
"partition": "partition-uuid"
}'
```
### Use Cases for Partition-Specific Software
1. **Architecture-Specific Partitions**: GPU partitions with CUDA libraries, ARM partitions with ARM-optimized software
2. **License Management**: Commercial software available only on specific partitions
3. **Performance Optimization**: Different optimized builds for different hardware configurations
4. **Access Control**: Research groups with access to specialized software on designated partitions
## Example Workflow
Here's a complete example of setting up a GPU partition with specialized software:
```bash
# 1. Add GPU partition
curl -X POST "https://your-waldur.example.com/api/marketplace-provider-offerings/{offering_uuid}/add_partition/" \
-H "Authorization: Token your-token" \
-H "Content-Type: application/json" \
-d '{
"partition_name": "gpu-v100",
"cpu_arch": "x86_64/intel/skylake_avx512",
"gpu_arch": "nvidia/cc70",
"max_cpus_per_node": 40,
"def_cpu_per_gpu": 4,
"max_mem_per_node": 384000,
"max_time": 2880,
"default_time": 120,
"qos": "gpu",
"priority_tier": 1,
"exclusive_user": true
}'
# 2. Associate CUDA software catalog with GPU partition
curl -X POST "https://your-waldur.example.com/api/marketplace-provider-offerings/{offering_uuid}/add_software_catalog/" \
-H "Authorization: Token your-token" \
-H "Content-Type: application/json" \
-d '{
"catalog": "cuda-catalog-uuid",
"enabled_cpu_family": ["x86_64"],
"enabled_cpu_microarchitectures": ["skylake_avx512"],
"partition": "gpu-partition-uuid"
}'
```
## Partition Architecture Filtering
Partitions can be filtered by their CPU and GPU architecture fields, enabling users to find partitions matching specific hardware requirements.
### Available Filters
| Filter | Type | Description |
|--------|------|-------------|
| `cpu_arch` | string (icontains) | Filter by CPU architecture substring (e.g., `zen3`, `x86_64`) |
| `gpu_arch` | string (icontains) | Filter by GPU architecture substring (e.g., `nvidia`, `cc90`) |
| `has_gpu` | boolean | Filter partitions with (`true`) or without (`false`) GPU architecture |
### Examples
```bash
# Find partitions with AMD Zen3 CPUs
curl "https://your-waldur.example.com/api/marketplace-offering-partitions/?cpu_arch=zen3"
# Find partitions with NVIDIA GPUs
curl "https://your-waldur.example.com/api/marketplace-offering-partitions/?gpu_arch=nvidia"
# Find all GPU-equipped partitions
curl "https://your-waldur.example.com/api/marketplace-offering-partitions/?has_gpu=true"
# Find CPU-only partitions
curl "https://your-waldur.example.com/api/marketplace-offering-partitions/?has_gpu=false"
```
### Connecting Software to Partitions
The `gpu_arch` field on partitions and the `gpu_architectures` field on software targets enable matching software to compatible hardware. For example, to find which partitions can run software requiring `nvidia/cc90`:
```bash
# 1. Find software targets requiring nvidia/cc90
curl "https://your-waldur.example.com/api/marketplace-software-targets/?gpu_arch=nvidia/cc90"
# 2. Find partitions providing nvidia/cc90
curl "https://your-waldur.example.com/api/marketplace-offering-partitions/?gpu_arch=nvidia/cc90"
```
## Integration Considerations
### SLURM Configuration Mapping
When configuring OfferingPartition models, ensure the parameters align with your actual SLURM cluster configuration:
1. **Resource Limits**: Set realistic limits that match hardware capabilities
2. **QOS Integration**: Ensure QOS names match those defined in SLURM
3. **Time Limits**: Align with cluster policies and user expectations
4. **Architecture Targeting**: Match CPU families/microarchitectures with actual hardware
### Software Catalog Strategy
Consider these approaches when associating software catalogs with partitions:
1. **Global Catalog**: Single catalog available across all partitions
2. **Partition-Specific**: Different catalogs for different partition types
3. **Hybrid Approach**: Base catalog globally + specialized catalogs per partition
## Permissions
### Partition Management (Offering Managers)
- **OfferingPartition**: Offering managers can create/modify SLURM partition configurations through offering actions
- Requires `UPDATE_OFFERING` permission on the offering
### Software Catalog Association (Offering Managers)
- **OfferingSoftwareCatalog**: Offering managers can associate catalogs with partitions through offering actions
- Must have `UPDATE_OFFERING` permission on the offering

### Marketplace Software Catalogs
# Marketplace Software Catalogs
This guide covers the software catalog system in Waldur's marketplace, including support for EESSI (European Environment for Scientific Software Installations), Spack, and other software catalogs.
## Overview
The software catalog system allows marketplace offerings to expose large collections of scientific and HPC software packages from external catalogs. Instead of manually tracking individual software installations, offerings can reference comprehensive software catalogs with thousands of packages. Waldur supports multiple catalog sources including:
- **EESSI**: Binary runtime environment with pre-compiled HPC software
- **Spack**: Source-based package manager for scientific computing
- **Future support**: conda-forge, modules, and custom catalogs
## Architecture
### Unified Catalog Loader Framework
Waldur uses a unified catalog loader framework that provides:
- **BaseCatalogLoader**: Abstract base class for all catalog loaders
- **EESSICatalogLoader**: Loader for EESSI catalogs from new API format
- **SpackCatalogLoader**: Loader for Spack catalogs from repology.json format
- **Extensible design**: Support for additional catalog types
### Data Models
The system uses relational models for efficient storage and querying:
- **SoftwareCatalog**: Represents a software catalog (e.g., EESSI 2023.06, Spack 2024.12)
- **SoftwarePackage**: Individual software packages within catalogs
- **SoftwareVersion**: Specific versions of packages
- **SoftwareTarget**: Architecture/platform-specific installations or build variants
- **OfferingSoftwareCatalog**: Links offerings to available catalogs
### Catalog Types
- **binary_runtime**: Pre-compiled software ready to use (EESSI)
- **source_package**: Source packages requiring compilation (Spack)
- **package_manager**: Traditional package managers (future: conda, pip)
- **environment_module**: Module-based software stacks
## Loading Software Catalogs
### EESSI Catalog Loading
The EESSI loader uses the new EESSI API format which supports both main software packages and extensions (Python packages, R packages, etc.).
#### Load EESSI Catalog
```bash
# Load EESSI catalog (dry run first to see what will be created)
DJANGO_SETTINGS_MODULE=waldur_core.server.settings uv run waldur load_eessi_catalog --dry-run
# Load the actual catalog with extensions
DJANGO_SETTINGS_MODULE=waldur_core.server.settings uv run waldur load_eessi_catalog
# Load without extensions
DJANGO_SETTINGS_MODULE=waldur_core.server.settings uv run waldur load_eessi_catalog --no-extensions
# Update existing catalog with new data
DJANGO_SETTINGS_MODULE=waldur_core.server.settings uv run waldur load_eessi_catalog --update-existing
```
#### EESSI Command Options
- `--catalog-name`: Name of the software catalog (default: EESSI)
- `--catalog-version`: EESSI version (auto-detected from API if not provided)
- `--api-url`: Base URL for EESSI API (default: /add_software_catalog/" \
-H "Authorization: Token your-token" \
-H "Content-Type: application/json" \
-d '{
"catalog": "",
"enabled_cpu_family": ["x86_64", "aarch64"],
"enabled_cpu_microarchitectures": ["generic"]
}'
```
## Understanding Software Catalog Targets
### EESSI Architecture Targets
EESSI provides software optimized for different CPU architectures and microarchitectures:
#### Common CPU Targets
- `x86_64/generic` - General x86_64 compatibility
- `x86_64/intel/haswell` - Intel Haswell and newer
- `x86_64/intel/skylake_avx512` - Intel Skylake with AVX-512
- `x86_64/amd/zen2` - AMD Zen2 architecture
- `x86_64/amd/zen3` - AMD Zen3 architecture
- `aarch64/generic` - General ARM64 compatibility
- `aarch64/neoverse_n1` - ARM Neoverse N1 cores
#### EESSI Extension Support
The new EESSI API format includes support for extension packages:
- **Python packages**: NumPy, SciPy, TensorFlow, PyTorch, etc.
- **R packages**: Bioconductor, CRAN packages
- **Perl modules**: CPAN modules
- **Ruby gems**: Scientific Ruby libraries
- **Octave packages**: Signal processing, optimization
Extensions are linked to their parent software packages via a many-to-many relationship. A single extension can belong to multiple parents (e.g., `adwaita-icon-theme` can be an extension of both GTK3 and GTK4). The EESSI loader collects parent information from all versions of an extension, not just the first.
### Spack Build Variants
Spack supports flexible build configurations through targets:
#### Target Types
- `build_variant/default` - Standard build configuration
- `platform/windows` - Windows-compatible packages
- `external/system` - System-provided packages (detectable)
- `build_system/build-tool` - Build tools and compilers
#### Spack Categories
- `build-tools` - Compilers, build systems, make tools
- `detectable` - Externally provided packages
- `windows` - Windows compatibility
- Custom categories based on package metadata
### Why Targets Matter
1. **Performance**: Architecture-specific builds can be 20-50% faster
2. **Compatibility**: Ensures software runs on target hardware
3. **Instruction Sets**: Leverages specific CPU features (AVX, NEON, etc.)
4. **HPC Requirements**: Critical for scientific computing workloads
5. **Build Flexibility**: Spack provides multiple build configurations
## Available API Endpoints
The software catalog system provides the following API endpoints:
- **marketplace-software-catalogs**: View and manage software catalogs
- **marketplace-software-packages**: Browse software packages within catalogs
- **marketplace-software-versions**: View software versions for packages
- **marketplace-software-targets**: View architecture-specific installations
### Discover Available Catalog Versions
Staff users can check what catalog versions are available upstream without creating anything:
```bash
curl "https://your-waldur.example.com/api/marketplace-software-catalogs/discover/" \
-H "Authorization: Token your-token"
```
Example response:
```json
[
{
"name": "EESSI",
"catalog_type": "binary_runtime",
"latest_version": "2025.06",
"existing": true,
"existing_version": "2024.01",
"update_available": true
},
{
"name": "Spack",
"catalog_type": "source_package",
"latest_version": "2026.01.15",
"existing": false,
"existing_version": null,
"update_available": false
}
]
```
| Field | Type | Description |
|-------|------|-------------|
| `name` | string | Catalog name (EESSI or Spack) |
| `catalog_type` | string | Catalog type identifier |
| `latest_version` | string or null | Detected upstream version, null if detection failed |
| `existing` | boolean | Whether a catalog record exists in the database |
| `existing_version` | string or null | Version of the existing catalog record |
| `update_available` | boolean | True when upstream version differs from existing |
This endpoint makes lightweight HTTP calls to the upstream sources (EESSI API, Spack repology) to detect the latest version. It does not download package data or modify the database. Requires staff permissions.
### Software Catalog Management Actions
Offering-software catalog associations are managed through offering actions:
- `add_software_catalog`: Associate a catalog with an offering
- `update_software_catalog`: Update catalog configuration for an offering
- `remove_software_catalog`: Remove catalog association from offering
These actions are available on the `marketplace-provider-offerings` endpoint.

```bash
# Add software catalog to offering
curl -X POST "https://your-waldur.example.com/api/marketplace-provider-offerings/{offering_uuid}/add_software_catalog/" \
-H "Authorization: Token your-token" \
-H "Content-Type: application/json" \
-d '{
"catalog": "catalog-uuid",
"enabled_cpu_family": ["x86_64", "aarch64"],
"enabled_cpu_microarchitectures": ["generic"]
}'
```
### Update Offering Software Catalog Configuration
```bash
# Update software catalog configuration for an offering
curl -X PATCH "https://your-waldur.example.com/api/marketplace-provider-offerings/{offering_uuid}/update_software_catalog/" \
-H "Authorization: Token your-token" \
-H "Content-Type: application/json" \
-d '{
"offering_catalog_uuid": "offering-catalog-uuid",
"enabled_cpu_family": ["x86_64", "aarch64"],
"enabled_cpu_microarchitectures": ["generic", "zen3"]
}'
```
### Remove Software Catalog from Offering

2. **Fetch**: Download catalog data from remote sources
3. **Transform**: Convert source format to unified data models
4. **Load**: Create or update database records
5. **Report**: Provide statistics and completion status
Both loaders handle:
- **Extension packages**: Link child packages to one or more parent software packages
- **Multiple architectures**: Support diverse target platforms
- **Metadata preservation**: Store catalog-specific information
- **Error recovery**: Continue processing despite individual failures
## Permissions
### Catalog Management (Staff Only)
- **SoftwareCatalog**: Only staff can create/modify catalogs
- **SoftwarePackage**: Only staff can manage package information
- **SoftwareVersion**: Only staff can manage version data
- **SoftwareTarget**: Only staff can manage target information
- **Discover endpoint**: Only staff can query upstream sources for available versions
### Offering Integration (Offering Managers)
- **OfferingSoftwareCatalog**: Offering managers can associate catalogs with their offerings through offering actions (`add_software_catalog`, `update_software_catalog`, `remove_software_catalog`)
## Integration Details
### EESSI API Format
The EESSI loader uses the dict-based format from [EESSI API PR #11](https://github.com/EESSI/api_data/pull/11) with structured objects for `module` and `required_modules`:
```json
{
"timestamp": "2026-01-27T10:00:00Z",

]
}
]
}
}
}
```
#### Key Fields
| Field | Type | Description |
|-------|------|-------------|
| `module` | object | Structured module info: `full_module_name`, `module_name`, `module_version` |
| `required_modules` | array of objects | Each with `full_module_name`, `module_name`, `module_version` |
| `gpu_arch` | object | Map of CPU arch to GPU arch lists (e.g., `{"x86_64/generic": ["nvidia/cc70"]}`) |
| `extensions` | array | Bundled packages with `type`, `name`, `version` |
| `toolchain_families_compatibility` | array | Compatible toolchain families (e.g., `"2023b_foss"`) |
#### Extension Structure
In the EESSI API, each version of an extension references its parent software. The loader collects parent references from **all** versions, so an extension that references different parents across versions will be linked to all of them via the `parent_softwares` many-to-many relationship.

### Developer's Guide to OpenAPI Schema Generation in Waldur
# Developer's Guide to OpenAPI Schema Generation in Waldur
This document provides an in-depth explanation of our approach to generating a high-quality OpenAPI 3 schema for the Waldur API using `drf-spectacular`. A well-defined schema is critical for API documentation, client generation, automated testing, and providing a clear contract for our API consumers.
We heavily customize `drf-spectacular`'s default behavior to produce a schema that is not only accurate but also rich with metadata, developer-friendly, and reflective of Waldur's specific architecture and conventions.
---
## Quick Reference
**Which tool should I use?**
| Task | Solution |
|------|----------|
| Add/modify parameters for one endpoint | `@extend_schema` decorator on view method |
| Custom serializer field representation | Extension in `openapi_extensions.py` |
| Filter which endpoints appear in schema | `disabled_actions` on ViewSet or modify `openapi_generators.py` |
| Schema-wide transformations | Hook in `schema_hooks.py` |
| Document authentication schemes | Authentication extension in `openapi_extensions.py` |
**Validation command:**
```bash
uv run waldur spectacular --validate
```
---
## 1. Architectural Overview
`drf-spectacular` generates a schema by introspecting your Django Rest Framework project. Our customizations hook into this process at four key stages, each handled by a different component:
| Component | File | Responsibility | When to Use |
| :---------------------------------- | :---------------------- | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :----------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Endpoint Enumerator** | `openapi_generators.py` | **Discovering Endpoints.** Controls *which* API endpoints and methods are included in the schema. | When you need to globally filter out views or methods based on a project-specific convention (e.g., a `disabled_actions` property on a viewset). |
| **Schema Inspector (`AutoSchema`)** | `openapi_inspector.py` | **Analyzing Individual Endpoints.** The main workhorse. It inspects a single view/method to determine its parameters, request/response bodies, description, operation ID, and other details. | For the majority of customizations related to a specific endpoint's representation, like adding custom parameters, modifying descriptions, or adding vendor extensions. |
| **Extensions** | `openapi_extensions.py` | **Handling Custom Components.** Provides explicit schema definitions for custom classes (Authentication, Serializer Fields, Serializers) that `drf-spectacular` cannot introspect automatically. | When you have a reusable custom class (e.g., `GenericRelatedField`) that needs a consistent representation across the entire schema. |
| **Post-processing Hooks** | `schema_hooks.py` | **Modifying the Final Schema.** Functions that run on the fully generated schema just before it's rendered. They are used for global search-and-replace operations, refactoring, and complex structural changes. | For broad, cross-cutting changes like adding a header to all list endpoints, refactoring common parameters into components, or implementing complex polymorphic schemas. |
The generation process flows like this:
**Enumerator** → **Inspector** (for each endpoint) → **Extensions** (as needed by Inspector) → **Schema Hooks** → **Final OpenAPI YAML/JSON**
---
## 2. The Core Inspector: `WaldurOpenApiInspector`
This class, located in `openapi_inspector.py`, is our custom subclass of `AutoSchema` and contains the most significant logic for tailoring the schema endpoint-by-endpoint.
### Key Methods and Use-Cases
#### `get_operation(...)`
- **Purpose**: To enrich the generated "operation" object with Waldur-specific metadata and logic.
- **Edge Cases Handled**:
1. **HEAD method for Lists**: We map the `HEAD` HTTP method to a "count" operation for list views. The inspector provides a custom description and a simple `200` response. Crucially, it returns `None` for detail views (`/api/users/{uuid}/`), effectively hiding this non-sensical operation.
2. **Custom Permissions Metadata**: This is a powerful feature for our frontend developers. If a view action has a `_permissions` attribute (e.g., `create_permissions`), the inspector extracts this data and injects it into the schema under a custom `x-permissions` vendor extension. This allows the frontend to understand the permissions required for an action without hardcoding them.
```yaml
# Example Output
"/api/projects/":
post:
summary: "Create a new project"
x-permissions:
- permission: "project.create"
scopes: ["customer"]
```
#### `get_description()`
- **Purpose**: To pull the docstring from the correct viewset *action* (`create`, `retrieve`, `my_action`) rather than from the view class itself.
- **Convention**: **Developers must write clear, concise docstrings on viewset action methods.** These docstrings are what users will see in the API documentation.
#### `get_operation_id()`
- **Purpose**: To generate clean, predictable, and code-generator-friendly operation IDs.
- **Convention**: The default behavior is modified to produce IDs like `projects_list`, `projects_create`, `projects_retrieve`. A special case for non-create `POST` actions (e.g., custom actions) uses a shorter format to avoid redundancy. This consistency is vital for generated API clients.
#### `get_override_parameters()`
- **Purpose**: To dynamically add query parameters based on the response serializer.
- **Use-Case**: Our `RestrictedSerializerMixin` allows users to request a subset of fields via the `field` query parameter (e.g., `?field=name&field=uuid`). This method introspects the response serializer, gets all its possible field names, and automatically generates the `OpenApiParameter` for `field` with a complete `enum` of available values. This provides excellent auto-complete and validation in tools like Swagger UI.
#### `_postprocess_serializer_schema(...)`
- **Purpose**: To modify a serializer's schema *after* it has been generated.
- **Use-Case**: Our serializers can have an `optional_fields` override. This method respects that override by removing those fields from the `required` array in the final schema. This is a clean way to tweak serializer requirements for the API without complex serializer inheritance.
---
## 3. Specialized Handlers: Extensions
Located in `openapi_extensions.py`, these classes provide a modular way to handle custom components.
### Authentication Extensions
- **`WaldurTokenScheme`**: Maps `waldur_core.core.authentication.TokenAuthentication` to OpenAPI token auth scheme.
- **`WaldurSessionScheme`**: Maps `waldur_core.core.authentication.SessionAuthentication` to OpenAPI cookie auth scheme.
- **`OIDCAuthenticationScheme`**: Maps `waldur_core.core.authentication.OIDCAuthentication` to OpenAPI Bearer token scheme.
These extensions ensure our custom DRF authentication classes are correctly documented as standard OpenAPI security schemes.
### Field Extensions
- **`GenericRelatedFieldExtension`**:
- **Problem**: `drf-spectacular` doesn't know how to represent our custom `GenericRelatedField`.
- **Solution**: This extension tells the generator to simply represent it as a `string` (which, in our case, is a URL). This avoids schema generation errors and provides a simple, accurate representation.
- **`IPAddressFieldExtension`**:
- **Problem**: DRF's `IPAddressField` supports three protocols: `ipv4`, `ipv6`, and `both` (default). The default introspection doesn't capture this nuance.
- **Solution**: This extension generates appropriate schemas based on the field's `protocol` attribute:
- `protocol="ipv4"` → `{"type": "string", "format": "ipv4"}`
- `protocol="ipv6"` → `{"type": "string", "format": "ipv6"}`
- `protocol="both"` → `oneOf` with both IPv4 and IPv6 formats
### Creating Custom Extensions
When you need to handle a custom class that `drf-spectacular` cannot introspect:
```python
from drf_spectacular.extensions import OpenApiSerializerFieldExtension
class MyFieldExtension(OpenApiSerializerFieldExtension):
target_class = "myapp.fields.MyCustomField"
def map_serializer_field(self, auto_schema, direction):
# Return OpenAPI schema dict
return {"type": "string", "format": "my-format"}
```
---
## 4. Endpoint Discovery: `WaldurEndpointEnumerator`
Located in `openapi_generators.py`, this class controls which endpoints are included in the schema.
- **Purpose**: The default enumerator might include all possible HTTP methods that a view *could* support. Our `WaldurEndpointEnumerator` is smarter.
- **Mechanism**: It respects the `disabled_actions` list property on our viewsets. If an action (e.g., `'destroy'`) is in `disabled_actions`, the corresponding method (`DELETE`) will be excluded from the schema for that endpoint.
- **Convention**: To disable an API endpoint, add its action name to the `disabled_actions` list on the `ViewSet`. The API documentation will automatically update to reflect this.
---
## 5. Global Transformations: Schema Hooks
Located in `schema_hooks.py`, these functions perform powerful, sweeping modifications to the entire generated schema. They are the last step in the process.
- **Design Principle**: Use hooks for cross-cutting concerns that affect many endpoints, or for complex transformations that are difficult to achieve within the inspector.
### Key Hooks and Their Purpose
- **`refactor_pagination_parameters`**:
- **Best Practice**: This hook implements the DRY (Don't Repeat Yourself) principle. It finds all instances of `page` and `page_size` parameters, moves their definition to the global `#/components/parameters/` section, and replaces the inline definitions with `$ref` pointers. This reduces schema size and improves consistency.
- **`add_result_count_header`**:
- **Purpose**: To document that all our paginated list endpoints return the `x-result-count` header.
- **Mechanism**: It identifies list endpoints (by checking if `operationId` ends in `_list`), defines a reusable header in `#/components/headers/`, and adds a reference to it in the `2xx` responses of those endpoints.
- **`make_fields_optional`**:
- **Problem**: Endpoints using `RestrictedSerializerMixin` can return a variable subset of fields. How do we represent this?
- **Solution**: This hook finds any operation that has a `field` query parameter. For those operations, it recursively traverses their response schemas and removes the `required` property from all objects. This correctly signals to API consumers that any field might be absent if not explicitly requested.
- **`transform_paginated_arrays`**:
- **Purpose**: To simplify the schema structure for paginated responses.
- **Mechanism**: `drf-spectacular` often creates named components like `PaginatedUserList`. This hook finds all such components, inlines their array definition wherever they are referenced, and then removes the original component definition. The result is a slightly more verbose but flatter and often easier-to-understand schema for the end-user.
- **`add_polymorphic_attributes_schema`**:
- **This is the most advanced and powerful hook in our arsenal.**
- **Problem**: The `attributes` field on the "Create Order" endpoint is polymorphic. Its structure depends entirely on the `offering_type` of the marketplace offering.
- **Solution**: We use OpenAPI's `oneOf` keyword to represent this polymorphism.
- **Mechanism**: The hook acts as a pre-processing step. It dynamically:
1. Iterates through all registered marketplace plugins (`waldur_mastermind.marketplace.plugins`).
2. For each plugin, it finds the serializer responsible for validating the `attributes` field.
3. It uses a temporary `AutoSchema` instance to generate a schema for that specific serializer's fields.
4. It adds this generated schema to `#/components/schemas/` with a unique name (e.g., `OpenStackInstanceCreateOrderAttributes`).
5. Finally, it modifies the `OrderCreateRequest` schema to replace the `attributes` field with a `oneOf` that references all the dynamically generated schemas, plus a generic fallback.
- **Architectural Significance**: This demonstrates how hooks can be used to generate schema fragments dynamically by introspecting parts of the application (in this case, the plugin system) that are outside the immediate scope of a DRF view.
- **Other Hooks**: `postprocess_drop_description`, `postprocess_fix_enum`, `remove_waldur_cookie_auth`, `adjust_request_body_content_types` are utility hooks for cleaning up and standardizing the final output.
---
## 6. Query Parameters and Enum Definitions
### Ordering Parameters
When implementing ordering functionality for API endpoints, proper OpenAPI schema documentation is crucial for API consumers. Waldur uses the convention of `o` as the ordering parameter name (configured in `ORDERING_PARAM`).
#### Best Practice: Explicit Enum Definitions
Instead of using a generic `str` type for ordering parameters, define explicit enums that list all supported ordering fields:
```python
@extend_schema(
parameters=[
OpenApiParameter(
"o",
{"type": "string", "enum": [
"project_name", "-project_name",
"resource_name", "-resource_name",
"provider_name", "-provider_name",
"name", "-name"
]},
OpenApiParameter.QUERY,
description="Order results by field",
),
],
)
@action(detail=True)
def items(self, request, uuid=None):
# Implementation...
```
This approach generates proper OpenAPI schema:
```yaml
- in: query
name: o
schema:
type: string
enum:
- project_name
- -project_name
- resource_name
- -resource_name
- provider_name
- -provider_name
- name
- -name
description: Order results by field
```
#### Benefits
- **API Documentation**: Clear enumeration of supported ordering fields
- **Client Generation**: Generated clients include proper validation and auto-completion
- **Frontend Integration**: UI components can dynamically generate ordering controls
- **API Testing**: Testing tools can validate ordering parameters automatically
#### Implementation Pattern
1. **Define the enum schema** in the `@extend_schema` decorator
2. **Include both ascending and descending options** (prefix with `-` for descending)
3. **Map to database fields** in your filtering logic:
```python
def filter_invoice_items(items, ordering=None):
if ordering:
ordering_map = {
'project_name': 'project_name',
'-project_name': '-project_name',
'resource_name': 'resource__name',
'-resource_name': '-resource__name',
# ... more mappings
}
db_ordering = ordering_map.get(ordering)
if db_ordering:
items = core_utils.order_with_nulls(items, db_ordering)
return items
```
---
## 7. Nullable Fields and SDK Client Generation
When a model ForeignKey is nullable (`null=True`), the corresponding serializer field **must** declare `allow_null=True`. Without this, the OpenAPI schema will not mark the field as nullable, and auto-generated SDK clients (Python, TypeScript, Go) will crash when parsing a `null` value from the API response.
**Example bug**: A nullable FK serialized without `allow_null=True` causes the generated Python client to call `UUID(None)`, raising a `TypeError`.
```python
# Model
class AgentIdentity(models.Model):
created_by = models.ForeignKey(User, null=True, on_delete=models.SET_NULL)
# WRONG - missing allow_null=True
created_by = serializers.SlugRelatedField(slug_field="uuid", read_only=True)
# CORRECT - matches the model's nullable nature
created_by = serializers.SlugRelatedField(slug_field="uuid", read_only=True, allow_null=True)
```
**Rule**: Any time a serializer field maps to a nullable model field (FK with `null=True`, or `CharField(null=True)`, etc.), add `allow_null=True` to the serializer field. This applies to `SlugRelatedField`, `HyperlinkedRelatedField`, `PrimaryKeyRelatedField`, and plain fields alike.
**How to verify**: After making changes, run `uv run waldur spectacular --validate` and inspect the generated schema to confirm the field shows `nullable: true`.
---
## 8. Best Practices and Conventions
1. **Docstrings are the Source of Truth**: Write clear docstrings on viewset *action methods*. They become the official API descriptions.
2. **Use the Right Tool for the Job**:
- **View-specific logic?** Use the `WaldurOpenApiInspector`.
- **Reusable custom class?** Create an `Extension`.
- **Global rule for filtering endpoints?** Modify the `WaldurEndpointEnumerator`.
- **Schema-wide refactoring or complex polymorphism?** Write a `postprocessing_hook`.
3. **Leverage View Attributes for Metadata**: We use view attributes like `create_permissions` and `disabled_actions` to control schema generation. This co-locates API behavior and its documentation, making the code easier to maintain.
4. **Define Explicit Enums for Query Parameters**: For parameters like ordering (`o`), filtering, or status selection, always define explicit enum values in the schema instead of generic string types. This provides better documentation, client generation, and validation.
5. **Embrace Vendor Extensions (`x-`)**: For custom metadata that doesn't fit the OpenAPI standard (like our `x-permissions`), vendor extensions are the correct and standard way to include it.
6. **Strive for DRY Schemas**: Use hooks like `refactor_pagination_parameters` to create reusable components (`parameters`, `headers`, `schemas`). This keeps the schema clean and consistent.
7. **Handle Polymorphism with Hooks**: For complex conditional schemas (`oneOf`, `anyOf`), post-processing hooks are the most flexible and powerful tool available, as demonstrated by `add_polymorphic_attributes_schema`.
8. **Simplify for the Consumer**: Use extensions (`OpenStackNestedSecurityGroupSerializerExtension`) and hooks (`transform_paginated_arrays`) to simplify complex or deeply nested objects where the full detail is unnecessary for the API consumer. The goal is a schema that is not just accurate, but also usable.
## 9. The OpenAPI Schema in the Broader Workflow
The OpenAPI schema is not merely a documentation artifact; it is a critical, machine-readable contract that drives a significant portion of our development, testing, and release workflows. Our CI/CD pipelines are built around the schema as the single source of truth for the API's structure.
The entire automated process is defined in the GitLab CI configurations for the `waldur-mastermind` and `waldur-docs` repositories.
### 1. Automated Generation
The process begins in the `waldur-mastermind` pipeline in a job named `Generate OpenAPI schema`.
- **Triggers**: This job runs automatically in two scenarios:
1. **On a schedule for the `develop` branch**: This ensures we always have an up-to-date schema reflecting the latest development state.
2. **When a version tag is pushed** (e.g., `1.2.3`): This generates a stable, versioned schema for a specific release.
- **Output**: The job produces a versioned `waldur-openapi-schema.yaml` file, which is stored as a CI artifact. This artifact becomes the input for all subsequent steps.
### 2. Automated SDK and Tooling Generation
The generated schema artifact immediately triggers a series of parallel jobs, each responsible for generating a specific client SDK or tool. This "schema-first" approach ensures that our client libraries are always perfectly in sync with the API they are meant to consume.
- `Generate TypeScript SDK`: For Waldur HomePort and other web frontends.
- `Generate Python SDK`: For scripting, integrations, and internal tools.
- `Generate Go SDK`: For command-line tools and backend services.
- `Generate Ansible modules`: Creates Ansible collections for configuration management and automation.
### 3. Continuous Delivery of SDKs
For development builds (from the `develop` branch), the newly generated SDKs are automatically committed and pushed to the `main` or `develop` branch of their respective GitHub repositories. This provides a continuous delivery pipeline for our API clients, allowing developers to immediately access and test the latest API changes through their preferred language.
### 4. Release and Versioning Workflow
For tagged releases, the workflow is more extensive:
1. **API Diff Generation**: A job named `Generate OpenAPI schema diff` is triggered. It fetches the schema of the *previous* release from the `waldur-docs` repository and compares it against the newly generated schema using `oasdiff`. It produces a human-readable Markdown file (`openapi-diff.md`) detailing exactly what has changed (endpoints added, fields removed, etc.).
2. **Documentation Deployment**: The new versioned schema (`waldur-openapi-schema-1.2.3.yaml`) and the diff file are automatically committed to the `waldur-docs` repository. The documentation site is then rebuilt, archiving the new schema and making the API changes visible in the release notes.
3. **Changelog Integration**: The main `CHANGELOG.md` in the `waldur-docs` repository is automatically updated with links to the new schema file and the API diff page. This provides unparalleled clarity for integrators, showing them precisely what changed in a new release.
4. **SDK Release**: The tagged version of each SDK is released, often involving bumping the version in configuration files (`pyproject.toml`, `package.json`) and pushing a corresponding version tag to the SDK's repository.
This automated, schema-driven workflow provides immense benefits:
- **Consistency**: All clients and documentation are generated from the same source, eliminating discrepancies.
- **Speed**: Developers get up-to-date SDKs without manual intervention, accelerating the development cycle.
- **Reliability**: The risk of human error in writing client code or documenting changes is significantly reduced.
- **Clarity**: Release notes are precise and automatically generated, giving integrators clear instructions on what to expect.

### Declaring resource actions
# Declaring resource actions
Any methods on the resource viewset decorated with
`@action(detail=True, methods=['post'])` will be recognized as resource
actions. For example:
``` python
class InstanceViewSet(structure_views.BaseResourceViewSet):
@action(detail=True, methods=['post'])
def start(self, request, uuid=None):
pass
@action(detail=True, methods=['post'])
def unlink(self, request, uuid=None):
pass
```
## Built-in actions on ResourceViewSet
The base `ResourceViewSet` provides several actions inherited by all resource ViewSets:
| Action | Method | Permission | Description |
|--------|--------|------------|-------------|
| `pull` | POST | Staff | Sync resource state from backend |
| `unlink` | POST | Staff | Delete resource from DB without backend operations |
| `set_erred` | POST | Staff | Force resource to ERRED state (useful for stuck transitional states) |
| `set_ok` | POST | Staff | Force resource to OK state and clear error fields |
The `set_erred` action accepts an optional request body with `error_message` and `error_traceback` fields.
## Complex actions and serializers
If your action uses serializer to parse complex data, you should declare
action-specific serializers on the resource viewset. For example:
``` python
class InstanceViewSet(structure_views.BaseResourceViewSet):
assign_floating_ip_serializer_class = serializers.AssignFloatingIpSerializer
resize_serializer_class = serializers.InstanceResizeSerializer
```
---
### Resource History API
# Resource History API
This guide covers resource-specific details for version history tracking.
For general information about the Version History API, see
[Version History API](version-history-api.md).
## Overview
Marketplace Resources have comprehensive version tracking that captures all
modifications to resource configuration, state, and metadata.
## Endpoints
```http
GET /api/marketplace-resources/{uuid}/history/
GET /api/marketplace-resources/{uuid}/history/at/?timestamp=
GET /api/marketplace-provider-resources/{uuid}/history/
GET /api/marketplace-provider-resources/{uuid}/history/at/?timestamp=
```
See [Version History API](version-history-api.md) for query parameters and
response format details.
## Tracked Fields
The following resource fields are tracked in version history:
| Field | Description |
|-------|-------------|
| `name` | Resource display name |
| `description` | Resource description |
| `slug` | URL-friendly identifier |
| `state` | Current state (Creating, OK, Erred, etc.) |
| `limits` | Resource quotas and limits |
| `attributes` | Offering-specific attributes |
| `options` | User-configurable options |
| `cost` | Current monthly cost |
| `end_date` | Scheduled termination date |

"end_date": null,
"downscaled": false,
"restrict_member_access": false,
"paused": false,
"plan": 123
}
}
```
## Actions That Create History
The following operations create version history entries:
| Action | Revision Comment |
|--------|------------------|
| Resource update | Updated via REST API |
| `set_slug` | Slug changed to {value} |
| `set_downscaled` | Downscaled changed to {value} |
| `set_paused` | Paused changed to {value} |
| `set_restrict_member_access` | Restrict member access changed to {value} |
## Django Admin Interface
The `ResourceAdmin` class inherits from `VersionAdmin`, providing a "History"
button in the Django admin interface. Staff users can:
- View all versions of a resource
- Compare differences between versions
- See who made each change and when
- Revert to a previous version (if needed)
Access the admin history at:
```text
/admin/marketplace/resource/{id}/history/
```
## Use Cases
### Debugging Configuration Issues
When a resource behaves unexpectedly, check its history to see what changed:
```bash
curl -H "Authorization: Token " \
"https://waldur.example.com/api/marketplace-resources/abc123/history/"
```
### Investigating Cost Changes
Track when and why resource costs changed by filtering history:
```bash
curl -H "Authorization: Token " \
"https://waldur.example.com/api/marketplace-resources/abc123/history/?\
created_after=2024-01-01T00:00:00Z"
```
### Point-in-Time Analysis
Check resource state before an incident:
```bash
curl -H "Authorization: Token " \
"https://waldur.example.com/api/marketplace-resources/abc123/history/at/?\
timestamp=2024-01-15T08:00:00Z"
```

### SLURM Periodic Usage Policy Configuration Guide
# SLURM Periodic Usage Policy Configuration Guide
## Overview
The `SlurmPeriodicUsagePolicy` enables automatic management of SLURM resource allocations with:
- Periodic usage tracking (monthly, quarterly, annual, or total)
- Automatic QoS adjustments based on usage thresholds
- Automatic period boundary reset (daily Celery beat task clears stale pauses/downscales when a new period starts)
- Carryover of unused allocations with configurable cap
- Grace periods for temporary overconsumption
- Integration with site agent for SLURM account management
## Available Actions
### Core Actions (Inherited from OfferingPolicy)
1. **`notify_organization_owners`** - Send email notifications to organization owners
2. **`notify_external_user`** - Send notifications to external email addresses
3. **`block_creation_of_new_resources`** - Block creation of new SLURM resources
### SLURM-Specific Actions
1. **`request_slurm_resource_downscaling`** - Apply slowdown QoS (sets `resource.downscaled = True`)
2. **`request_slurm_resource_pausing`** - Apply blocked QoS (sets `resource.paused = True`)
## How It Works
### Threshold Triggers
The policy checks usage percentages and triggers actions at different thresholds:
- **80%**: Notification threshold (hardcoded)
- **100%**: Normal threshold - triggers `request_slurm_resource_downscaling`
- **120%** (with 20% grace): Grace limit - triggers `request_slurm_resource_pausing`
### Site Agent Integration
When actions are triggered:
1. `request_slurm_resource_downscaling` → Site agent applies `qos_downscaled` (e.g., "limited")
2. `request_slurm_resource_pausing` → Site agent applies `qos_paused` (e.g., "paused")
3. Normal state → Site agent applies `qos_default` (e.g., "normal")
## Configuration Examples
### 1. Basic Notification Policy
Send notifications when usage reaches 80%:
```python
from waldur_mastermind.policy import models
policy = models.SlurmPeriodicUsagePolicy.objects.create(
offering=slurm_offering,
actions="notify_organization_owners",
apply_to_all=True,
grace_ratio=0.2,
carryover_enabled=True,
)
```
### 2. Progressive QoS Management
Apply slowdown at 100% usage with notifications:
```python
policy = models.SlurmPeriodicUsagePolicy.objects.create(
offering=slurm_offering,
actions="notify_organization_owners,request_slurm_resource_downscaling",
apply_to_all=True,
grace_ratio=0.2,
carryover_enabled=True,
)
```
### 3. Full Enforcement Policy
Complete enforcement with notifications, slowdown, and blocking:
```python
# Policy for 100% threshold
threshold_policy = models.SlurmPeriodicUsagePolicy.objects.create(
offering=slurm_offering,
actions="notify_organization_owners,request_slurm_resource_downscaling,block_creation_of_new_resources",
apply_to_all=True,
grace_ratio=0.2,
carryover_enabled=True,
)
# Additional policy for grace limit (would need separate instance)
grace_policy = models.SlurmPeriodicUsagePolicy.objects.create(
offering=slurm_offering,
actions="notify_external_user,request_slurm_resource_pausing",
apply_to_all=True,
grace_ratio=0.2,
options={"notify_external_user": "hpc-admin@example.com"},
)
```
### 4. Organization-Specific Policy
Apply policy only to specific organization groups:
```python
research_group = OrganizationGroup.objects.get(name="Research Universities")
policy = models.SlurmPeriodicUsagePolicy.objects.create(
offering=slurm_offering,
actions="request_slurm_resource_downscaling",
apply_to_all=False, # Not universal
grace_ratio=0.3, # 30% grace for research
carryover_enabled=True,
)
policy.organization_groups.add(research_group)
```
## Site Agent Configuration
Configure the site agent to handle QoS changes:
```yaml
# waldur-site-agent-config.yaml
offerings:
- name: "SLURM HPC Cluster"
backend_type: "slurm"
backend_settings:
# QoS mappings
qos_downscaled: "slowdown" # Applied at 100% usage
qos_paused: "blocked" # Applied at grace limit
qos_default: "normal" # Applied when below thresholds
# Periodic limits configuration
periodic_limits:
enabled: true
limit_type: "GrpTRESMins"
tres_billing_enabled: true
tres_billing_weights:
CPU: 0.015625
Mem: 0.001953125G
"GRES/gpu": 0.25
```
## Policy Parameters
### Core Parameters
- **`apply_to_all`**: `True` for all customers, `False` for specific groups
- **`organization_groups`**: Specific groups if not applying to all
- **`actions`**: Comma-separated list of actions to trigger
### SLURM-Specific Parameters
- **`period`**: Billing period length — `MONTH_1` (monthly, default), `MONTH_3` (quarterly), `MONTH_12` (annual), or `TOTAL` (cumulative, never resets). Controls how `_get_current_period()` computes the billing window for usage calculations and carryover. Note: if the offering's components have a `limit_period` set, it takes precedence over this field.
- **`limit_type`**: `"GrpTRESMins"`, `"MaxTRESMins"`, or `"GrpTRES"`
- **`tres_billing_enabled`**: Use TRES billing units vs raw values
- **`tres_billing_weights`**: Weight configuration for billing units
- **`grace_ratio`**: Grace period ratio (0.2 = 20% overconsumption). The pause threshold is `(1 + grace_ratio) * 100`%. For example, `grace_ratio=0.2` means resources are paused at 120% usage.
- **`carryover_enabled`**: Allow unused allocation carryover between periods
- **`carryover_factor`**: Maximum percentage of base allocation that can carry over from unused previous period (integer, 0-100, default: 50). For example, `carryover_factor=50` means up to 50% of the base limit can be carried over. Unused allocation from the previous period is `max(0, base - prev_usage)`, capped at `(carryover_factor / 100) * base`.
- **`raw_usage_reset`**: Reset SLURM raw usage at period transitions
- **`qos_strategy`**: `"threshold"` or `"progressive"`
## Usage Scenarios

carryover_enabled=True,
)
policy.organization_groups.add(consortium_members)
```
## API Usage
### Create Policy via API
```bash
curl -X POST https://waldur.example.com/api/marketplace-slurm-periodic-usage-policies/ \
-H "Authorization: Token YOUR_TOKEN" \
-H "Content-Type: application/json" \
-d '{
"scope": "OFFERING_UUID",
"actions": "notify_organization_owners,request_slurm_resource_downscaling",
"apply_to_all": true,
"grace_ratio": 0.2,
"carryover_enabled": true,
"component_limits_set": [
{
"type": "node_hours",
"limit": 1000
}
]
}'
```
### Check Policy Status
```bash
curl https://waldur.example.com/api/marketplace-slurm-periodic-usage-policies/POLICY_UUID/ \
-H "Authorization: Token YOUR_TOKEN"
```
## Evaluation and Testing
### Staff-Only API Actions
Three staff-only API actions allow testing and managing policy evaluation directly from the frontend or API without waiting for automatic triggers.
#### Dry Run
Calculate usage percentages and show what actions would be triggered without applying any changes.
```bash
curl -X POST https://waldur.example.com/api/marketplace-slurm-periodic-usage-policies/POLICY_UUID/dry-run/ \
-H "Authorization: Token STAFF_TOKEN" \
-H "Content-Type: application/json" \
-d '{}'
```
Optionally scope to a single resource:
```bash
curl -X POST .../POLICY_UUID/dry-run/ \
-H "Authorization: Token STAFF_TOKEN" \
-H "Content-Type: application/json" \
-d '{"resource_uuid": "RESOURCE_UUID"}'
```
Response includes per-resource: `usage_percentage`, current `paused`/`downscaled` state, and `would_trigger` actions.
#### Evaluate (Synchronous)
Run the full evaluation: calculate usage, apply actions (pause/downscale/notify), and create evaluation log entries.
```bash
curl -X POST https://waldur.example.com/api/marketplace-slurm-periodic-usage-policies/POLICY_UUID/evaluate/ \
-H "Authorization: Token STAFF_TOKEN" \
-H "Content-Type: application/json" \
-d '{}'
```
Response includes per-resource: `usage_percentage`, `actions_taken`, `previous_state`, and `new_state`.
#### Force Period Reset (Staff-Only)
Force-trigger a period boundary reset for a specific policy. This is useful after a Celery beat outage, or to immediately unblock resources that are still paused/downscaled from a previous period.
The action finds all active resources under the policy's offering that are currently paused or downscaled and have usage below 100% in the current period, then re-evaluates them synchronously — which removes the stale pause/downscale flags and sends STOMP messages to the site agent.
```bash
# Reset all stale paused/downscaled resources for a policy
curl -X POST https://waldur.example.com/api/marketplace-slurm-periodic-usage-policies/POLICY_UUID/force-period-reset/ \
-H "Authorization: Token STAFF_TOKEN" \
-H "Content-Type: application/json" \
-d '{}'
```
Optionally scope to a single resource:
```bash
curl -X POST .../POLICY_UUID/force-period-reset/ \
-H "Authorization: Token STAFF_TOKEN" \
-H "Content-Type: application/json" \
-d '{"resource_uuid": "RESOURCE_UUID"}'
```
Response includes per-resource: `usage_percentage`, `actions_taken`, `previous_state`, and `new_state`.
#### Frontend
Staff users see an **Evaluate** button on the SLURM policy configuration panel. This opens a dialog with:
- **Dry run** — read-only preview of what would happen
- **Evaluate now** — runs the full evaluation synchronously and shows results
### Management Commands
Three management commands are available for CLI-based testing and monitoring:
#### evaluate_slurm_policy
```bash
# Dry run: show what would happen without applying changes
waldur evaluate_slurm_policy --policy --dry-run
# Dry run for a single resource
waldur evaluate_slurm_policy --policy --resource --dry-run
# Run synchronously (blocking, results printed immediately)
waldur evaluate_slurm_policy --policy --sync
# Queue async Celery tasks (check worker logs for results)
waldur evaluate_slurm_policy --policy
```
#### slurm_policy_status
```bash
# Show all policies with resource states, evaluation logs, command history
waldur slurm_policy_status
# Single policy with more history
waldur slurm_policy_status --policy --logs 50 --commands 20
# Filter to a specific resource
waldur slurm_policy_status --policy --resource
```
#### cleanup_slurm_logs
```bash
# Manually trigger evaluation log cleanup (uses constance retention setting)
waldur cleanup_slurm_logs
```
## Monitoring and Observability
### Evaluation Log
Every policy evaluation creates a `SlurmPolicyEvaluationLog` record with:
- `usage_percentage` — resource usage at the time of evaluation
- `grace_limit_percentage` — the grace threshold that was applied
- `actions_taken` — list of actions triggered (e.g. `["downscale", "notify"]`)
- `previous_state` / `new_state` — `paused` and `downscaled` flags before and after
- `stomp_message_sent` — whether a STOMP message was published to the site agent
- `site_agent_confirmed` — whether the site agent reported success (null = pending)
- `site_agent_response` — full response from the site agent
### Command History
When STOMP messages are sent to the site agent, each generated SLURM command is recorded in `SlurmCommandHistory`:
- `command_type` — e.g. `fairshare`, `limits`, `qos`, `reset_usage`
- `shell_command` — the actual `sacctmgr` command
- `execution_mode` — `production` or `emulator`
- `success` / `error_message` — filled in by site agent report-back
### API Endpoints
```bash
# List evaluation logs for a policy (filterable by resource_uuid, billing_period)
GET /api/marketplace-slurm-periodic-usage-policies/POLICY_UUID/evaluation-logs/
# List command history for a policy (filterable by resource_uuid)
GET /api/marketplace-slurm-periodic-usage-policies/POLICY_UUID/command-history/
# Site agent reports command execution result
POST /api/marketplace-slurm-periodic-usage-policies/POLICY_UUID/report-command-result/
```
### Frontend Execution Log
The SLURM policy panel includes:
- **Status summary** — inline card showing last evaluation timestamp, count of paused/downscaled resources, and site agent confirmation status
- **Execution log** dialog with two tabs:
- **Evaluation History** — table with timestamps, resource names, usage percentages (colour-coded), action badges, and state transitions
- **Command History** — table with command types, shell commands, execution mode, and success/failure status
### Structured Events
Policy evaluations emit a `SLURM_POLICY_EVALUATION` event type, visible in the Waldur events system.
### Automatic Period Boundary Reset
A daily Celery beat task (`reset-slurm-policy-periods`, runs at 01:00) ensures that resources paused or downscaled in a previous period are automatically unblocked when the new period starts with zero usage.
For each `SlurmPeriodicUsagePolicy` (except those with `period=TOTAL`), the task:
1. Finds active resources that are still `paused=True` or `downscaled=True`
2. Checks if their usage in the **current** period is below 100%
3. If so, queues `evaluate_resource_against_policy` which clears the stale flags and sends STOMP messages to the site agent
This is idempotent — safe to re-run and catches up automatically after Celery beat outages. For immediate manual intervention, use the staff-only `force-period-reset` API action.
### Log Retention
Evaluation logs are automatically cleaned up by a daily Celery beat task (`cleanup-slurm-evaluation-logs`, runs at 03:00). The retention period is configurable via:
- **Constance setting**: `SLURM_POLICY_EVALUATION_LOG_RETENTION_DAYS` (default: 90 days)
- **HomePort admin**: Administration > Marketplace > SLURM policy
### Check Resource Usage (Django Shell)
```python
policy = SlurmPeriodicUsagePolicy.objects.get(offering=offering)
resource = Resource.objects.get(uuid="RESOURCE_UUID")
usage_percentage = policy.get_resource_usage_percentage(resource)
print(f"Current usage: {usage_percentage:.1f}%")
```
### Debug Carryover Calculations
Carryover allows unused allocation from the previous period to increase the current period's effective limit. The formula is:
1. `unused = max(0, base_limit - previous_period_usage)`
2. `cap = (carryover_factor / 100) * base_limit`
3. `carryover = min(unused, cap)`
4. `effective_limit = base_limit + carryover`
Example: base limit 1000, previous usage 400, carryover_factor 50 (i.e. 50%):
- `unused = max(0, 1000 - 400) = 600`
- `cap = (50 / 100) * 1000 = 500`
- `carryover = min(600, 500) = 500`
- `effective_limit = 1000 + 500 = 1500`
If the previous period was fully used (e.g., usage 1200), carryover is 0.
```python
settings = policy.calculate_slurm_settings(resource)
print(f"Carryover details: {settings['carryover_details']}")
print(f"Total allocation: {settings['carryover_details']['total_allocation']} node-hours")
```
## Site Agent Feedback Loop
After the site agent applies SLURM commands, it reports results back to Waldur:
1. Site agent receives STOMP message with `action: apply_periodic_settings`
2. Site agent executes `sacctmgr` commands via the backend
3. Site agent POSTs the result to `/api/marketplace-slurm-periodic-usage-policies/{policy_uuid}/report-command-result/`
4. Waldur updates `SlurmCommandHistory.success` and `SlurmPolicyEvaluationLog.site_agent_confirmed`
The STOMP message payload includes `policy_uuid` so the site agent knows which policy endpoint to report to.
## Best Practices
1. **Start with Notifications**: Begin with notification-only policies to understand usage patterns
2. **Use Dry Run First**: Run `waldur evaluate_slurm_policy --dry-run` or the frontend Dry Run button before enabling enforcement
3. **Test in Staging**: Validate policies in a test environment first
4. **Monitor Grace Periods**: Ensure grace ratios align with user needs
5. **Review Evaluation Logs**: Check the execution log regularly for unexpected actions
6. **Regular Review**: Review carryover and decay settings quarterly
7. **Clear Communication**: Inform users about thresholds and consequences
## Troubleshooting Common Issues
### Policy Not Triggering
- Check that `apply_to_all=True` or resource's customer is in `organization_groups`
- Verify component usage data exists for the current period
- Ensure resource is not in TERMINATED state
- Run `waldur evaluate_slurm_policy --policy --dry-run` to see current usage percentages
### QoS Not Changing
- Verify site agent configuration has correct QoS names
- Check site agent logs for SLURM command execution
- Ensure resource backend_id matches SLURM account name
- Check the command history endpoint or `waldur slurm_policy_status` for sent commands and site agent responses
### Incorrect Usage Calculations
- Review carryover settings and carryover factor
- Check billing period alignment — the `period` field controls boundaries: `MONTH_1` (monthly, default), `MONTH_3` (quarterly), `MONTH_12` (annual), `TOTAL` (cumulative). Note that offering component `limit_period` overrides this field if set.
- Verify component type matches between policy and usage data
### Resources Still Paused After New Period Starts
- The `reset-slurm-policy-periods` task runs at 01:00 daily and should clear stale pauses. Check Celery worker logs for errors.
- Use the staff `force-period-reset` endpoint to manually trigger a reset: `POST /api/marketplace-slurm-periodic-usage-policies/POLICY_UUID/force-period-reset/`
- Verify that the policy's `period` is not set to `TOTAL` (total-period policies never auto-reset)
### No Evaluation Logs Appearing
- Confirm the evaluation was triggered (check Celery worker logs)
- Verify the policy has resources in the offering
- Use the staff Evaluate button or `waldur evaluate_slurm_policy --sync` to run synchronously and see immediate results
### Site Agent Not Reporting Back
- Check that `policy_uuid` is present in the STOMP message payload
- Verify the site agent has network access to the Waldur API
- Check site agent logs for HTTP errors when POSTing to `report-command-result`
## Migration from Manual Management
For organisations transitioning from manual SLURM management:
1. **Audit Current Allocations**: Document existing quotas and QoS settings
2. **Create Initial Policies**: Start with generous grace periods
3. **Enable Notifications First**: Monitor before enforcing — use the execution log to verify calculations
4. **Dry Run Testing**: Use the staff dry-run feature to validate policy behaviour before enabling enforcement actions
5. **Gradual Enforcement**: Phase in QoS changes over 2-3 quarters
6. **User Training**: Educate users about automatic management

### Version History API
# Version History API
This guide explains the Version History API which provides version tracking for
various Waldur objects using django-reversion.
## Overview
The Version History API enables auditing and debugging by maintaining a complete
change history for key Waldur entities. Every modification to tracked fields
creates a timestamped snapshot that can be queried via the API.
Use cases:
- Audit trail for compliance requirements
- Debugging configuration issues
- Tracking changes over time
- Investigating state transitions
- Point-in-time recovery analysis
## Supported Models
The following models have version history endpoints:
| Model | Endpoint | Description |
|-------|----------|-------------|
| Customer | `/api/customers/{uuid}/history/` | Organization accounts |
| User | `/api/users/{uuid}/history/` | User accounts |
| SSH Key | `/api/keys/{uuid}/history/` | SSH public keys |
| Offering | `/api/marketplace-provider-offerings/{uuid}/history/` | Service offerings |
| Plan | `/api/marketplace-plans/{uuid}/history/` | Pricing plans |
| Resource | `/api/marketplace-resources/{uuid}/history/` | Marketplace resources |
| Invoice | `/api/invoices/{uuid}/history/` | Billing invoices |
## Architecture
```mermaid
graph TD
A[Object Change] --> B[django-reversion]
B --> C[Version Record]
C --> D[PostgreSQL]
E[History API] --> D
E --> F[Paginated Response]
```
The system uses django-reversion to capture object snapshots on save operations.
Each version stores:
- Serialized field data
- Timestamp of the change
- User who made the change (if authenticated)
- Revision comment describing the change
## API Endpoints
All models with version history support two endpoints:
### List Version History
Returns paginated version history for an object, ordered by most recent first.
```http
GET /api/{resource}/{uuid}/history/

- `privacy_policy_link`
- `state`, `paused_reason`
### Plans
Tracked fields include:
- `name`, `description`

## Implementation Notes
The version history functionality is implemented via `HistoryViewSetMixin` in
`waldur_core.core.views`. This mixin can be added to any ViewSet whose model
is registered with django-reversion.
To add history endpoints to a new ViewSet:
1. Register the model with django-reversion:
```python
import reversion
reversion.register(MyModel)
```
2. Add the mixin to the ViewSet:
```python
from waldur_core.core.views import HistoryViewSetMixin
class MyViewSet(HistoryViewSetMixin, ActionsViewSet):
queryset = MyModel.objects.all()
```
3. Optionally customize the serializer:
```python
class MyViewSet(HistoryViewSetMixin, ActionsViewSet):
history_serializer_class = MyCustomVersionSerializer
```

### Waldur Django Architecture
# Waldur Django Architecture
## Project Structure Overview
**Waldur MasterMind** is a Django-based cloud orchestration platform built with a highly modular, plugin-based architecture demonstrating advanced Django patterns and enterprise-level design principles.
## Settings Configuration
- **Hierarchical Settings**: `base_settings.py` (core) → `settings.py` (local) → specialized settings
- **Extension System**: Automatic discovery and registration of plugins via WaldurExtension
- **Multi-database**: PostgreSQL primary with optional read replicas
- **REST Framework**: Custom authentication (Token, SAML2, OIDC, OAuth)
- **Celery Integration**: Distributed task processing with priority queues
## Django Apps Organization
### Core Layer (`waldur_core/`)
- **`core`**: Foundation with extension system, base models, authentication
- **`structure`**: Organizational hierarchy (customers → projects → resources)
- **`users`**: User management with profiles

### Waldur Permission System Guide
# Waldur Permission System Guide
## Permission Factory Usage
**ALWAYS use `permission_factory` instead of manual `has_permission` checks in ViewSets.**
### For ViewSet Actions
```python
# Define permissions as class attributes
compliance_overview_permissions = [
permission_factory(PermissionEnum.UPDATE_CALL)
]
@action(detail=True, methods=["get"])
def compliance_overview(self, request, uuid=None):
# No manual permission check needed - handled by permission_factory
pass
```
### Permission Factory Patterns
- **Current Object**: `permission_factory(PermissionEnum.PERMISSION_NAME)` - no path needed
- **Related Object**: `permission_factory(PermissionEnum.PERMISSION_NAME, ["customer"])` - for related objects
- **Nested Path**: `permission_factory(PermissionEnum.PERMISSION_NAME, ["project.customer"])` - for nested relationships
### For perform_create/perform_destroy Methods
```python
# Use declarative permission attributes instead of manual perform_* overrides
def check_create_permissions(request, view, obj=None):
"""Check permissions for creating reviews."""
serializer = view.get_serializer(data=request.data)
serializer.is_valid(raise_exception=True)
proposal = serializer.validated_data["proposal"]
if not has_permission(
request.user,
PermissionEnum.MANAGE_PROPOSAL_REVIEW,
proposal.round.call,
):
raise exceptions.PermissionDenied()
def check_destroy_permissions(request, view, obj=None):
"""Check permissions for destroying reviews."""
if obj and not has_permission(
request.user,
PermissionEnum.MANAGE_PROPOSAL_REVIEW,
obj.proposal.round.call,
):
raise exceptions.PermissionDenied()
create_permissions = [check_create_permissions]
destroy_permissions = [check_destroy_permissions]
```
### When to Use Manual Checks
- Complex permission logic that doesn't map to standard object relationships
- Custom validation that requires dynamic permission targets
- Legacy code not yet refactored to declarative patterns
## Permission System Behavior
### Expiration Handling
- Basic permission queries (`get_users_with_permission`, `get_scope_ids`) include all roles regardless of expiration
- Expiration checking is explicit via `has_user(expiration_time=False)`, not implicit in `has_permission()`
- Use `has_user(expiration_time=current_time)` for time-based validation
### Error Handling
- `permission_factory` doesn't catch `AttributeError` and convert to `PermissionDenied`
- Test for actual exceptions the system raises, not ideal ones
- Handle `AttributeError` when accessing missing nested attributes
## Data Accuracy Critical Areas
- **User counting**: Always use `distinct()` on user_id to avoid double-counting users with multiple roles
- **Permission checks**: Handle edge cases (None scope, missing attributes) gracefully
- **Financial calculations**: Never approximate - exact calculations required
## Performance Optimization
### Query Optimization Strategy
- Use `select_related()` for foreign keys
- Use `prefetch_related()` for reverse relationships
- Use `distinct()` for deduplication instead of manual logic
- Accept 20-30 queries for complex operations rather than approximations
- Verify permission checks use reasonable query counts (≤3 for most operations)
---
### Waldur Testing Guide
# Waldur Testing Guide
## Test Writing Best Practices
### 1. Understand Actual System Behavior
- **Always verify actual behavior before writing tests** - Don't assume how the system should work
- **Test what the system actually does, not what you think it should do**
- Example: Basic permission queries don't automatically filter expired roles
### 2. Use Existing Fixtures and Factories
- **Always use established fixtures** - Don't invent your own role names
- Use `CustomerRole.SUPPORT` not `CustomerRole.MANAGER` (which doesn't exist)
- Use `fixtures.ProjectFixture()` for consistent test setup with proper relationships
- Use `factories.UserFactory()` for creating test users with proper defaults
### 3. Error Handling Reality Check
- **Test for actual exceptions, not ideal ones**
- If the system raises `AttributeError` for missing attributes, test for `AttributeError`
- Only test for `PermissionDenied` when the system actually catches and converts errors
### 4. Mock Objects for Complex Testing
- **Use Mock objects effectively for nested permission paths**
- Create realistic mock structures: `mock_resource.project.customer = self.customer`
- Test permission factory with multiple source paths: `["direct_customer", "project.customer"]`
- Mock objects help test complex scenarios without database overhead
### 5. Time-Based Testing Patterns
- **Understand explicit vs implicit time checking**
- Basic `has_permission()` doesn't check expiration times automatically
- Test boundary conditions: exact expiration time, microseconds past expiration
- Create roles with `timezone.now() ± timedelta()` for realistic time testing
### 6. Test Base Class Selection
Choose the right test base class for each test:
- **Default: `test.APITestCase`** — uses transaction rollback, much faster
- **Use `test.APITransactionTestCase`** only when:
1. `transaction.on_commit()` callbacks must fire (e.g., Celery task dispatch)
2. `IntegrityError` is deliberately triggered (breaks TestCase's wrapping transaction)
3. Threading or multi-process database access is needed
4. `responses.start()` in `setUp` for class-wide HTTP mocking (leaks across TestCase classes)
```python
# GOOD: Default to APITestCase
class MyTest(test.APITestCase):
def test_something(self):
...
# GOOD: Use APITransactionTestCase when on_commit is needed
class OrderProcessingTest(test.APITransactionTestCase):
def test_order_triggers_task(self):
# on_commit callback fires Celery task
...
```
A CI lint job (`scripts/analyze_transaction_test_cases.py --ci --baseline N`) enforces this — adding new unjustified `APITransactionTestCase` classes will fail the pipeline. The baseline is lowered as classes are migrated.
### 7. Performance Testing Considerations
- **Include query optimization tests** where appropriate
- Use `override_settings(DEBUG=True)` to count database queries
- Test with multiple users/roles to ensure performance doesn't degrade
### 8. System Role Protection
- **Test that system roles work correctly** even when modified
- System roles like `CustomerRole.OWNER` should maintain functionality
- Test that role modifications don't break core functionality
- Verify that predefined roles have expected permissions
### 9. Edge Case Testing
- **Test None values, missing attributes, and circular references**
- Handle `AttributeError` when accessing missing nested attributes
- Test with inactive users, deleted roles, removed permissions
- Verify behavior with complex nested object hierarchies
### 10. HTTP Mocking Patterns
**Preferred: `@responses.activate` per method** — fully isolated, no cleanup needed:
```python
class MyTest(test.APITestCase):
@responses.activate
def test_external_call(self):
responses.add(responses.GET, "https://api.example.com/data", json={"ok": True})
result = my_function()
self.assertEqual(result, {"ok": True})
```
**Class-wide mocking with `responses.start()`** — requires `APITransactionTestCase`:
```python
class ExternalAPITest(test.APITransactionTestCase):
"""responses.start() in setUp leaks state across TestCase classes."""
def setUp(self):
super().setUp()
responses.start()
responses.add(responses.GET, "https://api.example.com/data", json={"ok": True})
def tearDown(self):
responses.stop()
responses.reset()
super().tearDown()
```
Using `responses.start()` in `setUp` with `APITestCase` causes leaked mock state across test classes because `TestCase` doesn't fully reset process-level state between classes.
### 11. Multiple Inheritance Pitfall
When combining `APITransactionTestCase` with a mixin that extends `APITestCase`, Python's MRO can silently break `TransactionTestCase` behavior:
```python
# BAD: MRO puts TestCase._fixture_teardown first
class MyTest(test.APITransactionTestCase, SomeTestMixin):
... # SomeTestMixin extends APITestCase — TransactionTestCase teardown is skipped
# GOOD: Ensure all parents use TransactionTestCase, or use standalone setup
class MyTest(test.APITransactionTestCase):
def setUp(self):
super().setUp()
# Set up mocks directly instead of inheriting from a TestCase mixin
```
### 12. OpenStack Backend Test Patterns
When writing standalone backend tests that don't inherit from `BaseBackendTestCase`:
```python
class StandaloneBackendTest(test.APITransactionTestCase):
def setUp(self):
super().setUp()
self.fixture = openstack_fixtures.OpenStackFixture()
# Mock all 5 OpenStack clients
self.mock_admin = mock.patch("waldur_openstack.openstack_base.backend.AdminSession").start()
self.mock_session = mock.patch("waldur_openstack.openstack_base.backend.SessionManager").start()
self.mock_nova = mock.patch("waldur_openstack.openstack_base.backend.NovaClient").start()
self.mock_neutron = mock.patch("waldur_openstack.openstack_base.backend.NeutronClient").start()
self.mock_cinder = mock.patch("waldur_openstack.openstack_base.backend.CinderClient").start()
def tearDown(self):
mock.patch.stopall()
super().tearDown()
```
## Test Guidelines
- Test behavior, not implementation
- One assertion per test when possible
- Clear test names describing scenario
- Use existing test utilities/helpers
- Tests should be deterministic
## Debugging Complex Systems
When fixing performance or accuracy issues:
1. **Isolate the problem**:
- Run individual failing tests to understand specific issues
- Use `pytest -v -s` for verbose output with print statements
- Check if multiple tests fail for the same underlying reason
2. **Understand test expectations**:
- Read test comments carefully - they often explain intended behavior
- Check if tests expect specific error types
- Look for conflicting expectations between test suites
3. **Fix systematically**:
- Fix one root cause at a time
- After each fix, run full test suite to check for regressions
- Update related tests for consistency when changing behavior
4. **API changes require test updates**:
- When changing function signatures or default parameters, expect test failures
- Update tests for consistency rather than reverting functional improvements
- Document parameter behavior changes clearly
---
### Development guidelines
# Development guidelines
1. Follow [PEP8](https://python.org/dev/peps/pep-0008/)
2. Use [git flow](https://github.com/nvie/gitflow)
3. Write docstrings
## Flow for feature tasks
- Create a new branch from develop
```bash
git checkout develop
git pull origin develop
git checkout -b feature/task-id
```
- Perform brilliant work (don't forget about tests!)
- Verify that tests are passing.
- Push all changes to origin ( props.fetch(true)} />` | User-initiated refresh |
| **Automatic Polling** | `pullInterval` in Redux saga | Real-time data updates |
| **Query Invalidation** | `queryClient.invalidateQueries(['queryKey'])` | Cache invalidation |
## Error Handling and Loading States
### Consistent Error Display
```typescript
{groupsLoading ? (
organizationAutocomplete(query, prevOptions, page, {
field: ['uuid', 'name', 'url'],
o: 'name',
})
}
getOptionLabel={(option) => option.name}
getOptionValue={(option) => option.url}
/>
```
## Caching Strategies
### React Query Cache
- **Query-based caching**: Uses query keys for cache management
- **Automatic background refetching**: Keeps data fresh
- **Configurable stale time**: Typically 5 minutes for most queries
- **Request deduplication**: Prevents duplicate requests
### Redux Store Cache
- **Table data cached**: In Redux state for tables
- **Manual cache invalidation**: Explicit cache clearing
- **Optimistic updates**: Immediate UI updates for CRUD operations
## Best Practices
1. **New Components**: Use React Query with custom hooks
2. **Error Handling**: Consistent use of `LoadingErred` component with retry functionality
3. **Caching**: 5-minute stale time for most queries, longer for static data
4. **Refresh Strategy**: Always call `refetch()` after successful CRUD operations
5. **Loading States**: Use `isLoading` state for UI feedback
6. **API Integration**: Prefer `waldur-js-client` over direct fetch calls
7. **Form Validation**: Use async validation with API dependency checking
This data loading architecture demonstrates the application's evolution toward modern React patterns while maintaining backward compatibility with existing table infrastructure and Redux-based components.
## Migration Patterns
The application shows clear migration from Redux to React Query:
| Aspect | Redux Pattern | React Query Pattern |
|--------|---------------|---------------------|
| **Data Loading** | Redux actions + sagas | `useQuery` hooks |
| **Caching** | Redux store | Query cache |
| **Error Handling** | Redux error actions | Query error states |
| **Loading States** | Redux loading flags | `isLoading` state |
| **Refresh** | Dispatch actions | `refetch()` function |
| **Polling** | Saga intervals | Query refetch intervals |

### Architecture Guide
# Architecture Guide
This guide covers the application architecture, design patterns, and organizational structure of Waldur HomePort.
## Frontend Stack
- **React** with TypeScript for component development
- **Vite** for build tooling and development server
- **Redux** with Redux Saga for legacy state management
- **UI Router React** for navigation (state-based routing)
- **React Bootstrap** (Bootstrap 5) for UI components
- **React Final Form** for modern form handling
- **ECharts** for data visualization
- **Leaflet** with React Leaflet for mapping
- **TanStack React Query** for server state management
### Check Current Versions
Check all major dependencies
`yarn list react typescript vite redux @uirouter/react react-bootstrap react-final-form echarts leaflet @tanstack/react-query`
Check specific package version
yarn info version
## Key Architectural Patterns
### Module Organization
The codebase follows a feature-based folder structure under `src/`:
- Each domain (customer, project, marketplace, etc.) has its own folder
- Components are co-located with their specific business logic
- Shared utilities are in `core/` and `table/`
- API interactions use Redux patterns with sagas
### State Management
#### Modern Patterns (Use for New Development)
- **TanStack React Query**: Server state management and caching for API calls
- **React Final Form**: Local form state management
- **Local Component State**: useState and useReducer for UI state
- **Custom Hooks**: Reusable state logic and business operations
#### Legacy Patterns (Maintenance Only - Do Not Extend)
- **Redux Store**: Global state with dynamic reducer injection (legacy - avoid for new features)
- **Redux Saga**: Async operations and side effects (legacy - use React Query instead)
- **Table Store**: Specialized table data management in `src/table/` (legacy pattern)
### Navigation & Routing
The application uses **UI-Router for React** with state-based routing. Routes are defined in module-specific `routes.ts` files.
#### Route Definition Structure
```typescript
// Basic route with query parameters
{
name: 'protected-call.main',
url: 'edit/?tab&coi_tab',
component: lazyComponent(() =>
import('./update/CallUpdateContainer').then((module) => ({
default: module.CallUpdateContainer,
})),
),
params: {
coi_tab: {
dynamic: true, // Prevents component reload when param changes
},
},
}
```
#### Dynamic Parameters (Preventing Full Reloads)
When a query parameter controls nested tabs or filters within a page, mark it as `dynamic: true` to prevent full component reloads:
```typescript
// BAD: Changing coi_tab triggers full state reload
{
name: 'my-route',
url: 'page/?tab&subtab',
component: MyComponent,
}
// GOOD: Changing subtab only re-renders, no full reload
{
name: 'my-route',
url: 'page/?tab&subtab',
component: MyComponent,
params: {
subtab: {
dynamic: true,
},
},
}
```
#### Nested Tabs Pattern
For tabs within a page section that need URL synchronization:
1. **Add the parameter to the route URL** with `dynamic: true`:
```typescript
{
name: 'protected-call.main',
url: 'edit/?tab&coi_tab',
params: {
coi_tab: { dynamic: true },
},
}
```
2. **Use router hooks in the component**:
```typescript
import { useCurrentStateAndParams, useRouter } from '@uirouter/react';
const MyTabbedSection: FC = () => {
const { state, params } = useCurrentStateAndParams();
const router = useRouter();
const activeTab = params.my_tab || 'default';
const handleTabSelect = useCallback(
(key: string | null) => {
if (key) {
router.stateService.go(state.name, { ...params, my_tab: key });
}
},
[router, state, params],
);
return (
{/* Tab content */}
);
};
```
#### Main Page Tabs (usePageTabsTransmitter)
For main page-level tabs, use the `usePageTabsTransmitter` hook which automatically handles URL synchronization:
```typescript
const tabs = useMemo(
() => [
{ key: 'general', title: translate('General'), component: GeneralSection },
{ key: 'settings', title: translate('Settings'), component: SettingsSection },
],
[],
);
const {
tabSpec: { component: Component },
} = usePageTabsTransmitter(tabs);
return /)
## Project Overview
Waldur HomePort is a React-based web frontend for the Waldur MasterMind cloud orchestrator. It's a TypeScript application built with Vite that provides a comprehensive management interface for cloud resources, organizations, projects, and marketplace offerings.

### Button Variant Linting Rule
# Button Variant Linting Rule
## Overview
To ensure consistent use of design tokens and prevent regression to deprecated button styles, we've implemented a custom ESLint rule that enforces proper button variant usage throughout the codebase.
## Rule: `waldur-custom/enforce-button-variants`
This rule identifies and flags deprecated button variants and className patterns, suggesting modern design token alternatives.
### What it catches
#### Deprecated Button Variants
- `btn-outline-default` → `tertiary`
- `outline btn-outline-default` → `tertiary`
- `outline` → `tertiary`
- `light` → `tertiary`
- `light-danger` → `danger`
- `btn-light-danger` → `danger`
- `active-light-danger` → `text-danger`
- `btn-active-light-danger` → `text-danger`
- `active-light-primary` → `text-secondary`
- `btn-active-light-primary` → `text-secondary`
- `active-secondary` → `text-primary`
- `btn-active-secondary` → `text-primary`
- `outline-danger` → `danger`
- `btn-outline-danger` → `danger`
- `outline-warning` → `warning`
- `btn-outline-warning` → `warning`
#### Deprecated className patterns
- `btn-outline-default`
- `btn-active-light-danger`
- `btn-active-light-primary`
- `btn-active-secondary`
- `btn-light-danger`
- `btn-outline-danger`
- `btn-outline-warning`
- `btn-text-primary` (when used as className)
- `btn-text-dark`
- `btn-icon-danger`
- `btn-icon-primary`
### Example violations
```tsx
// ❌ These will trigger linting errors
Click me
Delete
Submit
Remove
// ✅ These are correct
Click me
Delete
Submit
Remove
```
### Auto-fixing
The rule provides automatic fixes for both `variant` props and many `className` patterns:
```bash
yarn lint:fix
```
This will automatically convert:
**Variant props:**
- `variant="btn-outline-default"` → `variant="tertiary"`
- `variant="light-danger"` → `variant="danger"`
- And other mappings listed above
**ClassName props:**
- `className="btn btn-outline-default"` → `className="btn btn-tertiary"`
- `className="btn btn-active-light-danger"` → `className="btn btn-text-danger"`
- `className="btn btn-text-primary btn-sm"` → `className="btn btn-sm"` (removes deprecated class)
- And other simple replacements
### Manual fixes required
Some cases still require manual fixes:
- Complex className expressions with template literals or variables
- Classes mixed with non-standard button classes (e.g., `btn-outline-dashed`)
- Conditional className logic
## Design Token Button Variants
### Primary Actions
- `primary` - Main call-to-action buttons
- `success` - Positive actions (save, submit, confirm)
- `danger` - Destructive actions (delete, remove)
- `warning` - Warning actions (pay invoice, etc.)
### Secondary Actions
- `tertiary` - Secondary actions, was `outline` or `btn-outline-default`
- `text-primary` - Text-only primary actions
- `text-secondary` - Text-only secondary actions
- `text-danger` - Text-only destructive actions
- `text-success` - Text-only positive actions
### Special Purpose
- `icon` - Icon-only buttons
- `flush` - Buttons with no background/border
## Benefits
1. **Consistency** - Ensures all buttons use standardized design tokens
2. **Maintainability** - Easier to update button styles globally
3. **Prevention** - Catches deprecated patterns before they're committed
4. **Guidance** - Provides clear suggestions for modern alternatives
5. **Automation** - Auto-fixes 90%+ of violations to reduce manual work
6. **Migration Support** - Helps transition from old button patterns to design tokens
## Running the linter
```bash
# Check for violations
yarn lint:check
# Auto-fix what's possible
yarn lint:fix
# Check specific file
yarn lint:check src/path/to/file.tsx
```
## Configuration
The rule is configured in `eslint.config.js` and the implementation is in `eslint-rules/enforce-button-variants.js`.
To modify the mappings or add new deprecated patterns, edit the constants at the top of the rule file:
- `DEPRECATED_BUTTON_VARIANTS` - variant prop values to flag
- `RECOMMENDED_VARIANTS` - mapping to modern alternatives
- `DEPRECATED_CLASS_NAMES` - className patterns to flag

- **Composition over inheritance** - Use dependency injection
- **Interfaces over singletons** - Enable testing and flexibility
- **Explicit over implicit** - Clear data flow and dependencies
- **Test-driven when possible** - Never disable tests, fix them
### Code Quality Requirements
- **Every commit must**:
- Compile successfully
- Pass all existing tests
- Include tests for new functionality
- Follow project formatting/linting
- **Before committing**:
- Run formatters/linters
- Self-review changes
- Ensure commit message explains "why"
### Error Handling
- Fail fast with descriptive messages
- Include context for debugging
- Handle errors at appropriate level
- Never silently swallow exceptions
## Testing Strategy
### Testing Frameworks
- **Unit Tests**: Vitest with React Testing Library for component testing
- **Integration Tests**: Cypress for end-to-end workflows
#### Check Testing Framework Versions
Check current versions
yarn info vitest @testing-library/react cypress version```
- Test files use `.test.ts/.test.tsx` extensions
- Setup files in `test/setupTests.js`
- Integrated coverage reporting
### Test Guidelines
- Test behavior, not implementation
- One assertion per test when possible
- Clear test names describing scenario
- Use existing test utilities/helpers
- Tests should be deterministic
### Test Code Sharing & Mocking
**Extracting Common Test Code**:
- Extract shared test data into separate files (e.g., `test-utils.ts`)
- Only mock what's actually imported by the component under test
- Don't mock exports that aren't used - it adds unnecessary complexity
- Verify import paths match actual usage (e.g., `./constants` vs `@waldur/marketplace/common/constants`)
**Vitest Mocking Constraints**:
- `vi.mock()` calls must be at the top level, not inside functions
- Vitest hoists mocks, so they can't reference variables defined later
- Share test data as exported constants, not function calls
- Mock the exact module path used in the component's imports
**Example Pattern**:
```js
// test-utils.ts
export const mockOffering = { uuid: '123', name: 'Test' };
export const mockPlan = { uuid: '456', name: 'Plan' };
// component.test.tsx
import { mockOffering, mockPlan } from './test-utils';
vi.mock('./constants', () => ({
getBillingPeriods: () => [...], // Only mock what's actually used
// Don't include ADD_PLAN_FORM_ID if component doesn't import it
}));
```
**Code Duplication Detection**:
- CI/CD uses `jscpd` with strict thresholds (typically 250 tokens)
- Extract common patterns properly - don't game the detector with formatting
- Shared test utilities reduce duplication and improve maintainability
## Development Guidelines
### TypeScript Configuration
- Uses `@waldur/*` path mapping for internal imports
- Strict TypeScript checking disabled for legacy compatibility
- Module resolution set to "Bundler" for Vite compatibility
### Code Style
- ESLint with flat config format enforced with TypeScript, React, and accessibility rules
- Prettier for code formatting (2 spaces, semicolons, single quotes)
- Import ordering enforced with `@waldur` imports grouped separately
- SCSS/CSS linting with Stylelint
- Husky for git hooks and pre-commit checks
#### Check Code Style Tool Versions
```
Check current versions
yarn info eslint prettier stylelint husky version```
### TypeScript and SDK Types
- **Always prefer SDK types over custom types** from `waldur-js-client` package
- Import types using `type` keyword: `import { type ComponentUsageCreateRequest } from 'waldur-js-client'`
- Common SDK types to use instead of custom interfaces:
- `ResourcePlanPeriod` - for plan periods with components
- `BaseComponentUsage` - for component usage data in periods
- `ComponentUsageCreateRequest` - for usage submission request bodies
- `ComponentUserUsageCreateRequest` - for user usage submission request bodies
- `ComponentUsage` - for general component usage data
- All marketplace API request/response types are available in the SDK
- When using React Final Form, use standard pattern: ` handleEdit()}
iconNode={
// Custom label
({ uuid: r.uuid, refetch })}
getInitialValues={(r) => ({ name: r.name })}
size="lg"
title={translate('Update')}
/>
);
```
#### DeleteButton Usage
```tsx
import { DeleteButton } from '@waldur/core/buttons';
import { myItemDestroy } from 'waldur-js-client';
export const MyDeleteButton = ({ row, refetch }) => (
myItemDestroy({ path: { uuid: r.uuid } })}
confirmTitle={translate('Delete item')}
confirmMessage={(r) => translate(
'Are you sure you want to delete {name}?',
{ name: {r.name} },
formatJsxTemplate
)}
successMessage={translate('Item deleted.')}
errorMessage={translate('Unable to delete item.')}
refetch={refetch}
/>
);
```

These components provide a comprehensive foundation for building consistent, accessible, and maintainable UI throughout the Waldur HomePort application.
## BaseDeployPage Component Pattern
The **BaseDeployPage** component (located at `src/marketplace/deploy/DeployPage.tsx`) serves as the central foundation for all marketplace offering deployment/ordering flows. It provides a standardized, multi-step form interface that can be configured for different types of cloud resources and services.
### Architecture and Purpose
BaseDeployPage handles:
- **Step Management**: Progressive form steps with validation and completion tracking
- **State Management**: Integration with Redux for form state and user selections
- **Form Validation**: Real-time validation and error display
- **Layout Management**: Sidebar layout with progress tracking
- **API Integration**: Order submission and error handling
- **Context-Aware Initialization**: Auto-populates organization/project based on context
### Key Configuration Interface
```js
interface DeployPageProps {
offering: Offering;
limits?: string[];
updateMode?: boolean;
previewMode?: boolean;
order?: OrderResponse;
plan?: Plan;
initialLimits?: AttributesType;
inputFormSteps: OfferingConfigurationFormStep[]; // Main configuration
}
```
### Step Definition Structure
```js
interface VStepperFormStep {
label: string; // Display name
id: string; // Unique identifier
component: React.ComponentType; // React component to render
params?: Record; // Additional configuration
fields?: Array; // Form fields managed by this step
required?: boolean; // Whether step is mandatory
requiredFields?: Array; // Fields that must be completed
isActive?: (data?: any) => boolean; // Dynamic step visibility
}
```
### Usage Example: OpenstackInstanceOrder
```js
// src/openstack/openstack-instance/OpenstackInstanceOrder.tsx
export const OpenstackInstanceOrder = (props) => (
```
### Base FormField Interface
All field components extend the `FormField` interface for consistent props:
```js
export interface FormField {
name?: string;
input?: WrappedFieldInputProps;
meta?: WrappedFieldMetaProps;
required?: boolean;
label?: ReactNode;
description?: ReactNode;
tooltip?: ReactNode;
validate?: Validator | Validator[];
disabled?: boolean;
hideLabel?: boolean;
normalize?: Normalizer;
format?: Formatter | null;
parse?: Parser;
noUpdateOnBlur?: boolean;
onBlur?(e): void;
containerClassName?: string;
spaceless?: boolean;
readOnly?: boolean;
}
```
### Configuration-Driven Forms
Forms are generated from configuration objects:
```js
export const SupportSettingsForm = ({ name }) => {
const fields = SettingsDescription.find((group) =>
group.description.toLowerCase().includes(name),
).items;
return (
<>
{fields.map((field) => (
))}
);
};
```
### Field Configuration Structure
```js
{
key: 'FIELD_NAME',
description: 'Field description',
default: 'default_value',
type: 'string' | 'boolean' | 'integer' | 'email_field' | 'text_field' | 'secret_field'
}
```
### Advanced Field Factory Pattern
For more complex scenarios, the system uses a comprehensive field factory:
```js
const getFieldComponent = useCallback((field, index, { key, ...props }) => {
if (field.component) {
return ) => void` | no | — | Click handler |
| `iconNode` | `ReactNode` | no | — | Icon to display |

### Simplicity Means
- Single responsibility per function/class
- Avoid premature abstractions
- No clever tricks - choose the boring solution
- If you need to explain it, it's too complex
## Process
### 1. Planning & Staging
Break complex work into 3-5 stages. Document in `IMPLEMENTATION_PLAN.md`:
```markdown
## Stage N: [Name]
**Goal**: [Specific deliverable]
**Success Criteria**: [Testable outcomes]
**Tests**: [Specific test cases]
**Status**: [Not Started|In Progress|Complete]
```
- Update status as you progress
- Remove file when all stages are done
### 2. Implementation Flow
1. **Understand** - Study existing patterns in codebase
2. **Test** - Write test first (red)
3. **Implement** - Minimal code to pass (green)
4. **Refactor** - Clean up with tests passing
5. **Commit** - With clear message linking to plan
### 3. When Stuck (After 3 Attempts)
**CRITICAL**: Maximum 3 attempts per issue, then STOP.
1. **Document what failed**:
- What you tried
- Specific error messages
- Why you think it failed
2. **Research alternatives**:
- Find 2-3 similar implementations
- Note different approaches used
3. **Question fundamentals**:
- Is this the right abstraction level?
- Can this be split into smaller problems?
- Is there a simpler approach entirely?
4. **Try different angle**:
- Different library/framework feature?
- Different architectural pattern?
- Remove abstraction instead of adding?
## Decision Framework
When multiple valid approaches exist, choose based on:
1. **Testability** - Can I easily test this?
2. **Readability** - Will someone understand this in 6 months?
3. **Consistency** - Does this match project patterns?
4. **Simplicity** - Is this the simplest solution that works?
5. **Reversibility** - How hard to change later?
## Project Integration
### Learning the Codebase
- Find 3 similar features/components
- Identify common patterns and conventions
- Use same libraries/utilities when possible
- Follow existing test patterns
### Important Reminders
**NEVER**:
- Use `--no-verify` to bypass commit hooks
- Disable tests instead of fixing them
- Commit code that doesn't compile
- Make assumptions - verify with existing code
**ALWAYS**:
- Commit working code incrementally
- Update plan documentation as you go
- Learn from existing implementations
- Stop after 3 failed attempts and reassess

### Migration to Generated Table Filters
# Migration to Generated Table Filters
This guide documents the transition from manually maintained table filters to automatically generated filters based on the OpenAPI schema.
## Motivation & Vision
### The Problem
Manually writing filter components for every API endpoint leads to:
- **Boilerplate**: Repetitive definitions of select fields, async paginators, and state management.
- **Inconsistency**: Discrepancies between the frontend filters and the actual API parameters (e.g., incorrect query param names, missing options).
- **Maintenance Burden**: When API changes (new filters, renamed parameters), developers must manually update the frontend code.
### The Solution
We generate filter components directly from the **OpenAPI schema** (`schema.json`). This ensures:
1. **Single Source of Truth**: The frontend filters always match the API definition.
2. **Type Safety**: Generated code uses TypeScript interfaces inferred from the schema.
3. **Automatic Updates**: Regenerating filters updates them to reflect API changes instantly.
4. **Standardization**: All filters use consistent UI components (``, ``, etc.) and behavior.
---
## Architecture
The generation process is driven by:
1. **`generate-filters.cjs`**: The Node.js script that parses the schema and outputs React components.
2. **`generate-filters-config.yaml`**: A configuration file for customization (overrides, ordering, labels).
3. **`waldur-js-client`**: Provides the TypeScript types and API client functions used by the generated code.
### Generated Output
The script produces `src/table/generated/{OperationId}Filter.tsx` files. Each file exports:
- `Pure{Name}Filter`: The presentation component.
- `{Name}Filter`: The connected component (wrapped in `reduxForm`).
- `{Name}FilterFormData`: TypeScript interface for form values.
- `{Name}FilterProps`: TypeScript interface for component props.
- `select{Name}Filter`: A selector to transform form values into API query parameters.
---
## Migration Process
To migrate a manual filter to a generated one, follow these steps:
### 1. Identify the OpenAPI Operation
Find the `operationId` for the list endpoint you are filtering.
Example: For `GET /api/customers/`, the operation ID might be `customers_list`.
### 2. Configure `generate-filters-config.yaml`
Add an entry for the operation if it doesn't exist. You can specify which filters to include (whitelist) or leave it empty to include all non-excluded filters.
```yaml
overrides:
customers_list:
# Optional: Customize component name (default: CustomersFilter)
componentName: CustomersFilter
# Optional: Whitelist specific filters to include
filters:
- name
- accounting_is_running
- organization_group
```
### 3. Run the Generator
Execute the generation script:
```bash
node generate-filters.cjs
```
This will create/update `src/table/generated/CustomersFilter.tsx`.
### 4. Replace the Manual Component
In your table definition (e.g., `CustomersList.tsx`), replace the manual filter component with the generated one.
**Before:**
```typescript
import { CustomersFilter } from './CustomersFilter'; // Manual file
```
**After:**
```typescript
import { CustomersFilter } from './generated/CustomersFilter'; // Generated file
```
### 5. Verify & Clean Up
- Check if the new filter behaves correctly in the UI.
- Verify that types are correct.
- Delete the old manual filter file.
---
## Configuration & Customization (`generate-filters-config.yaml`)
You can customize almost every aspect of the generated filters.
### Key Configuration Options
| Option | Description | Example |
| :--- | :--- | :--- |
| `label` | Custom label for the filter. | `label: "Organization"` |
| `component` | React component to use. | `component: "Autocomplete"` |
| `loadOptions` | API method for async loading. | `loadOptions: "customersList"` |
| `valueField` | Field to use as value. | `valueField: "uuid"` |
| `labelField` | Field to show in UI. | `labelField: "name"` |
| `mapTo` | Map a renamed filter back to a specific API param. | `mapTo: "organization_group_uuid"` |
| `options` | Hardcoded options for Select. | `options: [{ label: "Yes", value: true }]` |
### Example Configuration
```yaml
overrides:
customers_list:
filters:
- organization_group
# Override specific parameters across ALL operations
parameters:
organization_group:
label: "Organization group"
component: "Autocomplete"
loadOptions: "organizationGroupsList"
valueField: "uuid"
labelField: "name"
# The API expects 'organization_group_uuid', but we call the filter 'organization_group'
mapTo: "organization_group_uuid"
```
---
## Tips & Quirks
### 1. Renaming and `_uuid` Suffix
The generator automatically drops `_uuid` suffixes from filter names for cleaner code (e.g., `customer_uuid` becomes `customer`).
- **Quirk**: If you list filters in the `filters` whitelist in YAML, **you must use the renamed name** (e.g., `customer`, not `customer_uuid`), OR the original name if `mapTo` is correctly inferred.
- **Tip**: The generator logic handles the mapping back to the original parameter name in the `select{Name}Filter` selector.
### 2. Explicit Typing
Generated components are strictly typed.
- **Props**: `FunctionComponent` defines what props the filter accepts.
- **Form Data**: `FilterFormData` defines the shape of the form values.
- **Callbacks**: `getOptionLabel`/`getOptionValue` have explicit type annotations (e.g., `(option: Customer) => option.name`).
### 3. Autocomplete vs. Select
- **Autocomplete**: Uses `AsyncPaginate`. Requires `loadOptions`, `valueField`, and `labelField` to be set or inferred.
- **Select**: Uses standard `Select`. Used for enums, booleans, or fixed options.
### 4. Handling Props (`props.*`)
If a filter's options come from parent props (not an API call), use the `props.` prefix in configuration.
```yaml
parameters:
project_role:
options: "props.projectRoles" # Will generate props.projectRoles in component
```
The generator will:
1. Infer the `FilterProps` interface containing `projectRoles`.
2. Pass `props` to the component.
3. Render `options={props.projectRoles}`.
## Troubleshooting
### "My filter is missing"
- Check if it's in the `GenerateFiltersCI` exclusion list in `generate-filters.cjs`.
- Check if it's referenced in the `yaml` whitelist correctly.
### "My filter is a StringField but should be Autocomplete"
- This usually means the schema inference didn't detect it as a relation.
- **Fix**: Add an override in `generate-filters-config.yaml` setting `component: Autocomplete` and `loadOptions`.
### "TypeScript errors in generated code"
- Run `node generate-filters.cjs` to ensure the code is fresh.
- Check if `waldur-js-client` exports the types you expect.

### Form Migration Guide
# Form Migration Guide
The application contains **650+ form-related files** across three patterns, showing ongoing migration from Redux Form to React Final Form.
## Form Patterns Comparison
| Aspect | Redux Form (Legacy, ~68%) | React Final Form (Modern, ~21%) | VStepperForm (Multi-step, ~7%) |
|--------|------------|------------------|---------------------|
| **State Storage** | Redux store | Local component state | Shared across steps |
| **Performance** | Can cause unnecessary re-renders | Optimized subscription model | Step-based validation |
| **Complexity** | More boilerplate required | Minimal boilerplate | Step progression |
| **Persistence** | Persists across unmounts | Local to component lifecycle | Visual progress indicators |
| **Integration** | Deep Redux integration | Isolated, no external dependencies | Complex deployments |
## Implementation Examples
### Redux Form (Legacy)
```typescript
export const PolicyCreateForm: FC = (props) => (
);
```
### React Final Form (Modern)
```typescript
)}
/>
```
## Field Group Pattern
React Final Form uses reusable field groups for better organization:
```typescript
export const NameGroup = ({ customer }) => (
);
```
**Benefits**: Separation of concerns, reusability, maintainability, testability
## Key Patterns & Best Practices
### Validation
```typescript
export const validateProjectName = (value, _, props) =>
checkDuplicate(value, props) || checkPattern(value);
```
### Async Data Integration
```typescript
const { data, isLoading, error, refetch } = useQuery({
queryKey: ['CustomerProjects', selectedCustomer?.uuid],
queryFn: () => fetchCustomerProjects(selectedCustomer.uuid),
});
```
### Modern Form Submission
```typescript
const onSubmit = async (formData) => {
try {
await projectsCreate({ body: formData });
showSuccess(translate('Project created'));
closeDialog();
} catch (e) {
showErrorResponse(e, translate('Unable to create project'));
}
};
```
## Migration Strategy
- **New Components**: Use React Final Form
- **Legacy Components**: Maintain Redux Form
- **Hybrid Support**: Common field components work with both
- **Gradual Migration**: Phase out Redux Form over time
## Migration Detailed Guidelines
### Form Distribution (as of December 2025)
- **Redux Form (Legacy)**: ~467 files importing redux-form (~68%) - being phased out
- **React Final Form (Modern)**: ~146 files importing react-final-form (~21%) - preferred for new development
- **VStepperForm (Multi-step)**: ~50 files (~7%) - complex deployments
- **FormContainer usage**: ~96 files - Redux Form wrapper components
Note: Many files import redux-form for shared field components (SelectField, StringField, etc.) and table filters, not just form definitions.
### Key Forms by Category
- **User/Auth**: SigninForm, KeyCreateDialog (React Final Form)
- **Projects**: ProjectCreateDialog, team dialogs (React Final Form)
- **Resources**: OpenStack/VMware/Azure deploy steps (VStepperForm with Redux Form fields)
- **Administration**: Mixed - newer dialogs use React Final Form
- **Marketplace**: Deploy flows use VStepperForm, policy forms use React Final Form
- **Table Filters**: Predominantly Redux Form (high migration priority)
- **Proposals**: Multi-step wizards using VStepperForm
### Areas Needing Migration
1. **Table filters** - Most still use Redux Form field components
2. **Resource action dialogs** - Many use FormContainer pattern
3. **Invoice/Reporting filters** - Redux Form based
4. **Customer management** - Mixed, older dialogs need migration
## Post-Migration Cleanup
**Essential Commands**:
```bash
yarn deps:unused # Remove unused dependencies
yarn lint:check # Verify code standards
yarn test path/to/tests # Validate functionality
yarn tsc --noEmit # Check TypeScript compilation
```
**Cleanup Checklist**:
- [ ] Remove unused Redux Form constants (`FORM_ID`)
- [ ] Convert exported interfaces to internal if only used within component
- [ ] Delete orphaned Redux Form files
- [ ] Update imports to remove unused dependencies
- [ ] Verify form context boundaries for React Final Form
- [ ] Test modal structure and submit button access
## Error Handling Migration
**Issue**: Avoid unhandled promise rejections when migrating error handling.
**Solution**: Don't re-throw errors after `showErrorResponse()`:
```typescript
// ❌ Before (problematic)
catch (e) {
showErrorResponse(e, translate('Unable to create key.'));
throw e; // Causes unhandled promise rejection
}
// ✅ After (correct)
catch (e) {
showErrorResponse(e, translate('Unable to create key.'));
// Error handled, no re-throw needed
}
```
## Component Migration Patterns
### Key Changes in Migration
1. **Form State**: Redux Form HOC → React Final Form `
