` exactly; check `Token.objects.filter(key=...).exists()`. |
| All SCIM requests return 403 (with token) | Token user is not `is_staff`. | Promote the service account: `User.objects.filter(username=...).update(is_staff=True)`. |
| `POST /Groups` returns 400 `invalidValue` | `displayName` doesn't match the `waldur:` convention (see Group naming convention section above). | Build the displayName from the URLs in the Waldur admin (Customer/Project UUID + role name). |
| `POST /Groups` returns 400 with "Role X is not defined for project" | The role hasn't been created on this deployment. | Ensure the role exists; for system roles, access `CustomerRole.OWNER` / `ProjectRole.MANAGER` once (e.g. via `import_roles`) so the row is materialised. |
| Attribute set via SCIM is not visible | Field not in `SCIM_INBOUND_ALLOWED_ATTRIBUTES`, or the field was already owned by another source which wrote an empty value (which is preserved). | Widen `SCIM_INBOUND_ALLOWED_ATTRIBUTES`; inspect `User.attribute_sources` to see current owner. |
| `PATCH active=false` doesn't deactivate the user | `FEDERATED_IDENTITY_DEACTIVATION_POLICY=all_isds_removed` and the user still has another active source (e.g. `isd:puhuri`). | Switch to `any_isd_removed`, or remove the user from the other source first. |
| SCIM tests pass but real Okta connector fails | Real SCIM clients use exact `application/scim+json` content type and stricter envelopes than the test client. | Capture the failing request from Okta's system log; verify the SCIM envelope. |
## Security notes
- The endpoint is gated on `is_staff` — equivalent in authority to existing staff role-management APIs. Treat the service-account token like any other staff credential.
- Bearer tokens leak silently in proxy logs and error trackers. Consider configuring `User.token_lifetime` on the SCIM service account if your operational model assumes rotating credentials. (Note: the current `ScimBearerAuthentication` does not enforce `token_lifetime`-based expiry — see the security review section of the original MR.)
- `/scim/v2/` is outside the `/api/` prefix and excluded from the public OpenAPI schema.
- All writable attributes are gated by both `SCIM_INBOUND_ALLOWED_ATTRIBUTES` and `WRITABLE_USER_FIELDS`; privilege flags like `is_staff` / `is_superuser` / `is_active` (directly) / `token_lifetime` cannot be set via SCIM payloads.
- The SCIM filter parser only emits Django `Q` objects against a hard-coded attribute whitelist; values are parameterised by Django ORM.

### SCIM Entitlements (outbound push)
# SCIM Entitlements (outbound push)
> **Two different SCIM features in Waldur.** This page describes Waldur as a SCIM **client** pushing SSH entitlements *out to* a remote SCIM service (typically an HPC login-node manager). For Waldur as a SCIM **server** accepting user/group provisioning *in from* an external IdP (Okta, Entra ID, Keycloak), see [SCIM Identity Provider](scim-identity-provider.md). The two features are independent and can be enabled separately.
## Overview
Waldur integrates with SCIM (System for Cross-domain Identity Management) v2 API to synchronize user entitlements (SSH access permissions) with external identity providers. This integration enables automated management of SSH access to login nodes based on user roles and marketplace resource access.
**Features:**
- Automatic entitlement synchronization when user roles change
- Batch processing for efficient synchronization
- Scheduled reconciliation to catch missed updates
- Automatic cleanup of stale entitlements

```
## How It Works
### User Identification
Waldur uses `user.username` as the identifier when querying the SCIM service (`GET /scim/v2/Users/{username}`).
### Entitlement Format
Entitlements follow the URN format:
```
{urn_namespace}:res:{ssh_login_node}:{offering_user_username}:act:ssh
```
Where `{offering_user_username}` is the username from the `OfferingUser`.
Example:
```
urn:ietf:dev:res:login.example.org:johndoe:act:ssh
```
### Sync Logic
The sync process determines which entitlements a user should have based on:
1. **User Status**: User must be active
2. **Project Roles**: User must have active project roles
3. **Marketplace Resources**: Resources must be in `OK` state
4. **Offering Users**: Offering users must be in `OK` state with usernames
5. **SSH Endpoints**: Offerings must have SSH endpoints (`ssh://` URLs)
The sync process:
1. Fetches current entitlements from SCIM service
2. Calculates expected entitlements based on user's access
3. Adds missing entitlements
4. Removes stale entitlements
5. Clears all entitlements if user is inactive or has no roles
### Event-Driven Synchronization
Synchronization is automatically triggered when:
- User is granted a project role (`role_granted` signal)
- User's project role is revoked (`role_revoked` signal)
## Configuration
### Required Settings
Configure these settings in the Waldur admin panel (Constance):
| Setting | Type | Description |
|---------|------|-------------|
| `SCIM_MEMBERSHIP_SYNC_ENABLED` | Boolean | Master switch to enable/disable SCIM synchronization |
| `SCIM_API_URL` | String | Base URL of the SCIM API service (e.g., `https://scim.example.org`) |
| `SCIM_API_KEY` | Secret | API key for `X-API-Key` header authentication |
| `SCIM_URN_NAMESPACE` | String | URN namespace for entitlements (e.g., `urn:ietf:dev`) |
### Prerequisites
- Users must exist in SCIM service with usernames matching Waldur `user.username`
- Marketplace setup: active project roles, resources in `OK` state, offering users in `OK` state with usernames, SSH endpoints (`ssh://` URLs) configured in offerings
## API Reference

## Testing
### Manual Testing
#### 1. Test SCIM Service Connectivity
```bash
# Test ServiceProviderConfig endpoint
curl -sS \
-H 'X-API-Key: YOUR_API_KEY' \
-H 'Accept: application/scim+json' \
'https://scim.example.org/scim/v2/ServiceProviderConfig'
```
#### 2. List Users in SCIM
```bash
curl -sS \
-H 'X-API-Key: YOUR_API_KEY' \
-H 'Accept: application/scim+json' \
'https://scim.example.org/scim/v2/Users'
```
**Response**: Standard SCIM v2 ListResponse format with `totalResults` indicating number of users.
#### 3. Get Specific User
```bash
# Replace USERNAME with actual username from Waldur
curl -sS \
-H 'X-API-Key: YOUR_API_KEY' \
-H 'Accept: application/scim+json' \
'https://scim.example.org/scim/v2/Users/USERNAME'
```
#### 4. Test Entitlement Operations
```bash
# Add an entitlement (example)
curl -sS -X PATCH \
-H 'X-API-Key: YOUR_API_KEY' \
-H 'Accept: application/scim+json' \
-H 'Content-Type: application/scim+json' \
-d '{
"schemas": ["urn:ietf:params:scim:api:messages:2.0:PatchOp"],
"Operations": [{
"op": "add",
"path": "entitlements",
"value": [{"value": "urn:test:res:login.example.org:testuser:act:ssh"}]
}]
}' \
'https://scim.example.org/scim/v2/Users/USERNAME'
```
### Testing from Waldur
#### Via Django Shell
```python
from waldur_core.users.scim import tasks
from waldur_core.core.models import User
# Get a test user
user = User.objects.filter(username__isnull=False).first()
# Trigger sync for that user
tasks.sync_user_entitlements.delay(str(user.uuid))
```
#### Via API
```bash
# Trigger full sync (requires staff authentication)
curl -X POST \
-H 'Authorization: Token YOUR_TOKEN' \
'https://your-waldur-instance/api/users/scim_sync_all/'
```
## Troubleshooting
### Common Issues
#### User Not Found Errors
**Symptom**: `SCIM get_user failed for {username}: SCIM request failed [404]`
**Cause**: User does not exist in SCIM or username mismatch.
**Solution**: Verify user exists in SCIM with exact `user.username` from Waldur.
#### Sync Not Triggering
**Symptom**: Entitlements not updating when roles change
**Check**: `SCIM_MEMBERSHIP_SYNC_ENABLED`, configuration completeness, user has username and active project roles, marketplace resources with SSH endpoints exist.
#### Entitlements Not Being Added
**Symptom**: User has roles but no entitlements in SCIM
**Check**: Resources in `OK` state, offering users in `OK` state with usernames, SSH endpoints configured, user is active.
### Logging
SCIM operations are logged with the `waldur_core.users.scim` logger. Check logs for:
- `SCIM add X entitlements for user Y`
- `SCIM remove X stale entitlements for user Y`
- `SCIM clear all entitlements for user Y`
- `SCIM get_user failed for Y: {error}`
- `SCIM update failed for Y: {error}`
### Debugging
Enable debug logging to see detailed SCIM requests:
```python
import logging
logging.getLogger('waldur_core.users.scim').setLevel(logging.DEBUG)
```
This will log all SCIM API requests including URLs, methods, and responses.
## Implementation Details
### Username Matching
Waldur queries SCIM using `user.username`. The username must match the user identifier in your SCIM service.
### Entitlement Usernames
Entitlements use `OfferingUser.username` (not Waldur usernames).
### Error Handling
SCIM operations use graceful error handling: errors are logged as warnings, failed operations don't block other users, missing configuration causes tasks to skip silently.

### Table Growth Monitoring
# Table Growth Monitoring
Waldur includes a database table growth monitoring system that tracks PostgreSQL table sizes
over time. It detects abnormal growth patterns that may indicate bugs causing unbounded data
accumulation.
## Overview
The system consists of three components:
1. **Daily data collection** - A Celery task samples table sizes from PostgreSQL
2. **Historical storage** - The `DailyTableSizeHistory` model stores daily snapshots
3. **Growth analysis API** - An endpoint computes growth rates and raises alerts
## How It Works
### Data Collection
The `sample_table_sizes` Celery task runs daily and:
1. Queries PostgreSQL system catalogs for all user tables above a configurable size threshold
2. Records total size (including indexes), data-only size, and estimated row count
3. Stores one entry per table per day using `update_or_create`
4. Purges entries older than the configured retention period
The PostgreSQL query uses `pg_total_relation_size()`, `pg_relation_size()`, and
`pg_stat_user_tables.n_live_tup` to gather metrics.
### Growth Analysis
The API endpoint compares today's snapshot against snapshots from 7 and 30 days ago to
compute weekly and monthly growth percentages for both size and row count.
Growth percentage formula:
```text
growth_percent = (current_size - old_size) / old_size * 100
```
Tables are sorted by combined growth rate (weekly + monthly, descending). Alerts are
generated for any table exceeding the configured weekly or monthly threshold.
## Configuration
All settings are managed via Constance (runtime-configurable):
| Setting | Default | Description |
|---------|---------|-------------|
| `TABLE_GROWTH_MONITORING_ENABLED` | `True` | Master switch for the feature |
| `TABLE_GROWTH_MIN_SIZE_BYTES` | `1048576` (1 MB) | Minimum table size to track |
| `TABLE_GROWTH_RETENTION_DAYS` | `90` | Days of history to retain |
| `TABLE_GROWTH_WEEKLY_THRESHOLD_PERCENT` | `50` | Weekly growth % that triggers an alert |
| `TABLE_GROWTH_MONTHLY_THRESHOLD_PERCENT` | `200` | Monthly growth % that triggers an alert |
## API Endpoint

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:
1. Check recent code changes affecting these tables
2. Review the model's get_or_create() and update_or_create() calls
3. Verify foreign key cascade behavior
4. Consider adding cleanup tasks for temporary data

## 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.
## Billing models
Waldur supports two billing models for resource components, configurable per offering:
- **Monthly (Limit-based)**: Resources are billed each month based on reserved limits. This is the default for OpenStack Tenant offerings. Limits can be changed at any time, with billing adjusted on the current invoice.
- **Prepaid (One-time + Pre-paid)**: Resources are billed upfront for the full subscription period. The charge is calculated as `price × limit × months`. An end date is required. Mid-period limit changes create supplementary charges for the remaining period.
Both models can coexist on the same offering — for example, CPU cores can be prepaid while a management fee remains monthly. Custom components (e.g., consultancy hours) can use the "Maximum total" limit period for flat one-time charges.
For configuration details, see [Configuring billing model per component](../user-guide/service-provider-organization/adding-an-offering.md#configuring-billing-model-per-component).
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.

## 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.

### 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).

### 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.
## How Waldur maps its structure to FreeIPA groups
Waldur models each organization and each project as a FreeIPA group, and keeps
memberships in step with Waldur roles. Group names are built from the
organization or project UUID, behind a configurable prefix:
| Waldur object | FreeIPA group name |
|---|---|
| Organization | `org_` |
| Project | `project_` |
Only the prefix is configurable — the rest of the name is derived from the UUID.
The project group is made a member of its organization's group, and the
organization or project name is stored as the group description.
Synchronisation runs periodically, and reconciles in both directions: groups
that exist in Waldur but not in FreeIPA are created, and groups carrying the
prefix that no longer correspond to anything in Waldur are deleted.
### The prefix is an ownership marker
`FREEIPA_GROUPNAME_PREFIX` and `FREEIPA_USERNAME_PREFIX` (both `waldur_` by
default) are not cosmetic. They are how Waldur tells its own groups and users
apart from everything else in the directory: an object carrying the prefix is
treated as Waldur-managed and therefore subject to deletion once Waldur no
longer has a counterpart for it.
Both are edited in Homeport under **Administration → Configuration → Identity
providers → Providers**, on the **FreeIPA** card's **Edit** action:
[[Image: FreeIPA settings with the username and groupname prefixes]](img/freeipa-settings-prefix.png)
!!! danger "Never set a prefix to an empty value"
With an empty prefix, *every* group in the directory matches — including
FreeIPA's own built-ins such as `admins` and `ipausers` — and the next
synchronisation run would treat them all as stale and delete them. Waldur
rejects an empty prefix, and refuses to synchronise if one is already
stored, but do not attempt to work around this.
Changing the prefix on a running deployment is a **migration, not a toggle**.
The existing groups no longer match the new prefix, so Waldur stops recognising
them and recreates the whole set under the new name, leaving the old groups
orphaned in the directory. Plan the rename and clean up the old groups
deliberately.
### Using pre-existing GIDs
Waldur never assigns a `gidnumber` itself — it creates groups without one and
lets FreeIPA's own allocator choose, and it never reads or modifies the GID
afterwards. Once a group exists, synchronisation only updates its description
and membership.
That gives a straightforward way to pin a group to a **GID you already use**:
create the group in FreeIPA yourself, before Waldur first synchronises, using
the exact name from the table above and the `gidnumber` you want.
```bash
ipa group-add waldur_project_ --gid=8501
```
Waldur will adopt the existing group and keep its GID indefinitely. The same
applies to users — Waldur creates accounts without a `uidnumber`, so an account
pre-created with the desired UID keeps it.
!!! tip
To manage groups entirely yourself, turn off **Freeipa group synchronization
enabled** in the same panel (`FREEIPA_GROUP_SYNCHRONIZATION_ENABLED`). Waldur
then stops creating and deleting groups altogether, while still managing user
profiles.

### 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.
!!! tip
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

### OpenPortal integration
# OpenPortal integration
## Overview
OpenPortal is a distributed agent-based infrastructure management protocol that enables Waldur to integrate with remote HPC centres and resource providers. The integration supports award/project management, user provisioning, resource allocation, and usage reporting across institutional boundaries.
!!! note
OpenPortal is developed by the University of Bristol's Isambard Supercomputing Centre. Source code and documentation: [github.com/isambard-sc/openportal](https://github.com/isambard-sc/openportal)

### Components
| Component | Location | Purpose |
|---|---|---|
| Waldur OpenPortal module | `waldur_openportal/` | Backend integration with OpenPortal protocol |
| Marketplace OpenPortal Remote | `marketplace_openportal_remote/` | Marketplace processors for order/resource lifecycle |
| OpenPortal Bridge | External service | HTTP bridge between Waldur and OpenPortal network |

## Capabilities
### Supported operations
| Operation | Direction | OpenPortal Instruction |
|---|---|---|
| **Create project/award** | Waldur → Remote | `create_project` / `create_award` |
| **Update project** | Waldur → Remote | `update_project` / `update_award` |
| **Delete project** | Waldur → Remote | `remove_project` |
| **Add user to project** | Waldur → Remote | `add_user` |
| **Remove user** | Waldur → Remote | `remove_user` |
| **Set resource limits** | Waldur → Remote | `set_limit` |
| **Get resource limits** | Remote → Waldur | `get_limit` |

| **Set project quota** | Waldur → Remote | `set_project_quota` |
| **Sync offerings** | Remote → Waldur | `sync_offerings` |
### Award metadata (AwardDetails)
When creating or updating projects, the following metadata is transmitted:
- **name**, **description**: Project identification
- **start_date**, **end_date**: Project timeline
- **members**: Map of email → role
- **allocation**: Resource allocation amount with units (CPU-HR, GPU-HR, NHR, etc.)
- **breakdown**: Component-level allocation (e.g., `gpu_hours`, `interactive_cpu_hours`, `project_storage`)
- **award**: Link to award record on funding body system
- **call**: Link to the funding call
- **project_link**: Link to project page on awarding portal
- **renewal**: Link to renewal/extension request page
- **notes**: Append-only timestamped messages between portals
- **membership_control**: Policy for membership changes (`open`, `members_only`, `roles_only`, `locked`)
- **allowed_domains**: Email domain glob patterns permitted to join the project on the remote portal, e.g. `['*.ac.uk']`. An empty list allows no domains; omitting the field places no restriction
- **earliest_approve**: Earliest UTC time the remote portal may approve the award, giving the sender a window to make corrections before provisioning begins
#### Membership control
`membership_control` decides which side is authoritative when the two portals
disagree about who belongs to a project:
| Value | Meaning |
|---|---|
| `open` | The receiving portal manages membership freely |
| `members_only` | Roles are authoritative; membership is not |
| `roles_only` | Membership is authoritative; roles are not |
| `locked` | Both membership and roles are authoritative |
### Usage reporting
The integration supports pulling compute and storage usage:
- **Compute usage**: Daily per-user CPU/GPU/node usage
- **Storage usage**: Quota and consumption snapshots per volume
- **Date range filtering**: Query specific time periods
- **Report remapping**: Translate component names between systems
## Award lifecycle
Each award Waldur sends to a remote portal is tracked locally as a remote
project record, so that an operator can see what was sent, what the remote
portal confirmed, and what is still outstanding.
| State | Meaning |
|---|---|
| **Pending** | Award details have been sent but not yet confirmed. The remote portal may be awaiting human review |
| **Active** | The award was approved, the project exists on the remote portal, and confirmation was received |
| **Stale** | Nothing has been heard from the remote portal for an unexpectedly long time, so the local view may be out of date |
| **Error** | The request was rejected, or the connection to the remote portal is definitively broken |
| **Deleted** | The local resource was deleted. The record is kept for history and can be revived if a future resource is reconnected |
A record moves to **Stale** automatically once nothing has been heard about it
for 12 hours. This is a warning that the local view may be wrong, not that
anything has failed — it usually points at a connectivity problem somewhere in
the agent chain rather than at the award itself.
Every award keeps an audit trail of what was sent, what came back, and who
changed what locally, alongside the last set of details sent and the last set
the remote portal confirmed. When those two disagree, the difference is what is
still in flight.
### Managing an award
Organisation owners, support and staff can act on an award directly. Ordinary
project members can see awards for projects they have access to but cannot
change them.
| Action | Effect |
|---|---|
| **Add note** | Appends a timestamped message that travels to the remote portal with the next update |
| **Set allowed domains** | Changes which email domains may join the project remotely |
| **Set membership control** | Changes which side is authoritative for membership and roles |
| **Set earliest approve** | Sets the embargo time before which the remote portal may not approve |
| **Approve now** | Removes the embargo so the remote portal may approve immediately |
| **Hold indefinitely** | Pushes the embargo far into the future, parking the award until released with *Approve now* |
| **Reset to pending** | Clears a rejection locally and returns the award to Pending so changes or a resend can proceed. Sends nothing to the remote portal |
| **Resend request** | Sends the current award details to the remote portal again |
!!! note
*Reset to pending* only changes local state. If the remote portal rejected
the award for a reason that still applies, resending it will be rejected
again — fix the underlying cause first.
## Configuration
### Prerequisites
1. OpenPortal Bridge deployed and accessible via HTTP
2. Cluster agent(s) configured on remote HPC centres
3. Waldur `waldur_openportal` module enabled
### Helm configuration
Add the following to your Waldur Helm values:
```yaml
waldur:
openportal:
enabled: true
bridge_url: "https://bridge.example.com"
bridge_token: "your-bridge-api-token"
```
### Membership sync mode
When an incoming award lists someone as a member, Waldur can either invite them
or add them straight away. Which is right depends on the site's own onboarding
process, so it is a deployment setting,
`OPENPORTAL_MEMBERSHIP_SYNC_MODE`:
| Value | Behaviour |
|---|---|
| `invitation` (default) | Create a pending invitation. The user accepts, agrees to the terms and is provisioned locally before gaining access |
| `direct` | Create the account if needed and grant the role immediately |
Choose `invitation` where users must authenticate, accept an invitation and
agree to terms and privacy policies before local accounts are provisioned.
Choose `direct` where accounts are provisioned automatically and quickly, and a
second invitation at the receiving site would only confuse someone who has
already been invited by the awarding portal.
!!! warning
The default is `invitation`. A site that relies on members being added
directly must set this explicitly, otherwise members from incoming awards
will sit as pending invitations instead of gaining access.
Either way the award converges immediately: a pending invitation is reported
back to the awarding portal as membership, so it stops resending the update
rather than waiting for the person to accept. Re-running the sync does not
create a second invitation.
### Creating a remote allocation offering
1. Navigate to **Service Provider** settings
2. Create a new offering with type **OpenPortal Remote**
3. Configure:
- Bridge URL and authentication
- Remote project identifier mapping
- Component definitions (CPU, GPU, RAM, storage)
## Monitoring
### Health checks
The integration includes a health check endpoint:
```bash
# Check bridge connectivity
curl -H "Authorization: Token YOUR_TOKEN" \
https://waldur.example.com/api/openportal-remote-allocations/health/
```
### Usage synchronization
Usage data is pulled periodically via Celery tasks:
- `sync_usage`: Pulls latest usage reports from remote clusters
- `pull_allocation`: Full synchronization of single allocation
- `send_notifications`: Sends project expiration notifications
### Notification frequency
Per-project notification frequency is configurable to avoid notification fatigue:
- Notifications tracked per project with last-sent timestamps
- Configurable minimum interval between notifications
## Data flow for marketplace orders
1. **User creates order** → `CreateRemoteAllocationProcessor` → `create_allocation()` on bridge
2. **Limits change** → `UpdateRemoteAllocationLimitsProcessor` → `set_resource_limits()` on bridge
3. **User added** → Signal handler → `sync_users()` → `add_user()` on bridge
4. **Usage sync** → Periodic task → `get_usage_report()` from bridge → `ComponentUsage` update
## Version compatibility
Waldur requires OpenPortal 0.91.0 or later.
| OpenPortal Version | Waldur Module | Key Features |
|---|---|---|
| 0.91.x | Current | Award lifecycle tracking with audit history, allowed domains, approval embargo |
| 0.27.x | Superseded | AwardDetails with links, notes, membership control |
| 0.26.x | Superseded | Date range filtering on reports |
| 0.25.x | Superseded | Report remapping |
!!! tip
Upgrade every agent in the chain together — bridge, portal, provider,
clusters, cluster and the leaf agents. A chain running mixed versions is
not a supported configuration, and the resulting failures usually surface
as authentication or protocol errors far from the agent that is actually
out of date.
---
### OpenStack
# OpenStack
Waldur integrates with OpenStack-based clouds through a single OpenStack plugin. It
provisions and manages OpenStack projects (tenants) together with the compute, network and
storage resources inside them, and exposes them for self-service ordering through the Waldur
marketplace.
## Requirements
OpenStack releases known to work:
- Queens
- Rocky
- Stein
- Train
- Ussuri
- Victoria
- Wallaby
- Xena
- Yoga
- Zed
- Antelope
Newer releases are generally compatible, as Waldur talks to OpenStack through the standard
service clients (Keystone v3, Nova, Cinder, Neutron and Glance).
To integrate an OpenStack-based cloud as a shared provider, the following data is required:
- URL of Keystone's public endpoint (v3).
- Network access from the Waldur server to the public interfaces of Keystone, Nova, Cinder,
Neutron and Glance.
- Admin credentials (username/password) and the domain name (if a non-default domain is used).
- External network UUID — the network connected by default to the OpenStack projects (tenants)
that Waldur creates.
## Marketplace offerings
OpenStack is exposed to end users through three marketplace offering types:
- **OpenStack.Tenant** — provisions an OpenStack project (tenant) with quotas for cores, RAM and
storage, an internal network, a subnet and a router, and connects it to the external network.
- **OpenStack.Instance** — provisions a virtual machine inside a tenant.
- **OpenStack.Volume** — provisions a block-storage volume inside a tenant.
### Tenant provisioning options
When ordering a tenant, the following options are available:
- `subnet_cidr` — CIDR of the default private subnet.
- `availability_zone` — default availability zone for the tenant.
- `security_groups` — security groups to create in the tenant.
- `skip_connection_extnet` — do not connect the tenant to the external network.
- `skip_creation_of_default_router` — do not create the default router.
- `skip_creation_of_default_subnet` — do not create the default subnet.
### Offering options
Per-offering settings control how tenants behave:
- `storage_mode` — `fixed` for a single storage quota, or `dynamic` for per-volume-type quotas.
- `max_instances`, `max_volumes`, `max_security_groups` — upper bounds enforced within a tenant.
- `default_internal_network_mtu` — MTU applied to networks created in the tenant (68–9000).
### Default marketplace categories
Two of the three OpenStack offering types have a **default category** flag on a marketplace
category, used when Waldur auto-creates offerings during an OpenStack import:
| Flag | Used for |
|---|---|
| `default_vm_category` | the category new **instance** offerings are placed in |
| `default_volume_category` | the category new **volume** offerings are placed in |
At most one category may carry each flag; Waldur rejects an attempt to set a flag that another
category already holds. Both categories are created automatically, with their flags set, the first
time an OpenStack environment is imported — so under normal operation there is nothing to configure.
To set one by hand, go to **Administration → Marketplace → Categories** in Homeport, open the row's
actions menu and choose **Edit**. The flags are at the bottom of the dialog:
[Image: Default category flags in the category edit dialog]
They are also settable through the API as a staff user, and on the category in the Django admin site:
```bash
curl -X PATCH \
-H "Authorization: Token $WALDUR_TOKEN" \
-H "Content-Type: application/json" \
-d '{"default_vm_category": true}' \
https://waldur.example.com/api/marketplace-categories//
```
!!! note "`TENANT_CATEGORY_UUID` and friends are not something you need to set"
Older releases published `INSTANCE_CATEGORY_UUID`, `VOLUME_CATEGORY_UUID` and
`TENANT_CATEGORY_UUID` under `WALDUR_MARKETPLACE_OPENSTACK` in the `/api/configuration/`
response. Nothing has consumed them since 2023, and they are no longer published.
If you are on a release that still shows them, seeing `null` is harmless — no behaviour depends
on the value. In particular there is **no** `default_tenant_category` equivalent to the two
flags above: nothing in Waldur reads that flag, so a null `TENANT_CATEGORY_UUID` is expected
rather than a misconfiguration to fix.
## Supported resources
The plugin discovers and manages the full set of OpenStack resources:
- **Compute** — instances, flavors and server groups (affinity / anti-affinity, including soft
variants). Instances support cloud-init user data, config drive, SSH key injection, multiple
network ports and boot-from-volume.
- **Networking** — networks, subnets, ports, routers, floating IPs and security groups (ingress
and egress rules, TCP/UDP/ICMP, IPv4 and IPv6). Cross-tenant network sharing is supported via
RBAC policies (`access_as_shared` and `access_as_external`).
- **Storage** — volumes and volume types, with resize, retype and boot-from-image. Snapshots
and full instance backups are supported, each with a retention period after which they are
cleaned up automatically.
- **Images and availability zones** — images and per-resource availability zones for instances
and volumes.
Quotas are enforced and kept in sync at the service, tenant and project levels, and resource
state is reconciled with the backend on a periodic schedule.
## Billing
Tenant offerings are billed on quota limits using monthly components:
- **Cores** — vCPU limit.
- **RAM** — memory limit, in GB.
- **Storage** — total storage limit, in GB.
In `dynamic` storage mode, a separate storage component is created for each OpenStack volume
type (for example `storage_ssd`), so that each volume type can be billed independently.
## Organization-specific external networks
A specific external network can be assigned to all OpenStack tenants created by a given
organization on a given provider. When a tenant is created, Waldur resolves the external
network to connect to in the following order:
1. The external network set on the tenant itself.
2. The external network configured for the organization on that provider.
3. The provider's default external network.
The tenant's default router is then connected to the resolved external network, and the
tenant's external network reference is recorded for floating IP allocation.

### 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.

## Event processing architecture
The `event_process` mode uses WebSocket STOMP connections to receive real-time events from Waldur Mastermind
via RabbitMQ. The main loop combines event-driven processing with periodic reconciliation to ensure data
consistency even when STOMP messages are missed.

```
### Periodic reconciliation
Event-driven processing can miss updates due to transient STOMP disconnections or message loss.
The main loop includes a periodic reconciliation timer (default: 60 minutes, configurable via
`WALDUR_SITE_AGENT_RECONCILIATION_PERIOD_MINUTES` environment variable) that runs
`sync_offering_user_usernames()` for all STOMP-enabled offerings with a membership sync backend.
This reconciliation is lightweight — it only syncs usernames, not a full membership sync — and is
idempotent, so running it has no side effects when data is already consistent.
### STOMP subscription types
Each offering can subscribe to multiple object types depending on configuration:
- **ORDER**: Order processing events (requires `order_processing_backend`)
- **USER_ROLE**: Role grant/revoke events (requires `membership_sync_backend`)
- **RESOURCE**: Resource lifecycle events (requires `membership_sync_backend`)
- **SERVICE_ACCOUNT**: Service account events (requires `membership_sync_backend`)
- **COURSE_ACCOUNT**: Course account events (requires `membership_sync_backend`)
- **OFFERING_USER**: Offering user create/update events (requires `membership_sync_backend`)
- **IMPORTABLE_RESOURCES**: Resource import events (requires `resource_import_enabled`)
- **RESOURCE_PERIODIC_LIMITS**: Periodic limit updates (requires `periodic_limits.enabled`)
## Key plugin features
- **Automatic Discovery**: Plugins are automatically discovered via Python entry points
- **Modular Backends**: Each backend (SLURM, MOAB, MUP) is a separate plugin package
- **Independent Versioning**: Plugins can be versioned and distributed separately
- **Extensible**: External developers can create custom backends by implementing `BaseBackend`
- **Workspace Integration**: Seamless development with `uv workspace` dependencies
- **Multi-Backend Support**: Different backends for order processing, reporting, and membership sync

- **Advanced**: Supports both polling (`order_process`) and event-driven (`event_process`) modes
### Basic username management (`waldur-site-agent-basic-username-management`)
- **Purpose**: Provides base username management interface
- **Implementation**: Minimal placeholder implementation
- **Extensibility**: Template for custom username generation backends
### Rancher plugin (`waldur-site-agent-rancher`)
- **Communication**: HTTP REST API (Rancher v3, direct)
- **Components**: Project resourceQuota cap (CPU / memory / storage)
- **Features**:
- Direct project create / update / delete on a single Rancher cluster
- Per-namespace resource quotas + namespace creation
- Keycloak group membership sync via `keycloak-client` shared package
- Membership sync + order processing modes both supported
- **Client**: `RancherClient` (httpx-based) talking to one cluster per
offering (cluster_id is offering-level config)
### Rancher CRD-driven plugin (`waldur-site-agent-rancher-kc-crd`)
- **Communication**: Kubernetes API — writes `ManagedRancherProject`
CRs that the [`rancher-keycloak-operator`](https://github.com/waldur/rancher-keycloak-operator)
reconciles
- **Scope**: Membership sync only — no order processing, no usage
reporting (the operator owns Rancher + Keycloak mutations)
- **Multi-cluster**: One offering can hold N Resources, each with its
own `backend_id` = Rancher cluster ID. The plugin reads cluster_id
per-Resource at CR-build time
- **Features**:
- One CR per Waldur ResourceProject; operator translates to Rancher
project + project-level resourceQuota.limit + Keycloak groups +
PRTBs
- Drives RP FSM (`Creating → OK` on operator phase=Ready,
`→ Erred` on phase=Error) so the homeport UI reflects the
downstream reconcile state
- Per-RP Keycloak group naming so member-sync doesn't thrash a
shared cluster-level group
- **Client**: thin `kubernetes` Python wrapper for `apply` / `get` /
`list` / `delete` of CRs in one namespace
- **Pairs with**: operator `0.3.1`+ (recommended)

- Full `BaseBackend` and `BaseClient` method references
- Agent mode method matrix (which methods are called when)
- Usage report format specification with examples
- Unit conversion (`unit_factor`) explained
- Common pitfalls and debugging tips
- Testing guidance with mock patterns
- LLM-specific implementation checklist
See **[Plugin Development Guide](plugin-development-guide.md)**.
A ready-to-use plugin template is available at `docs/plugin-template/`.
## Plugin discovery mechanism
The core system automatically discovers plugins through Python entry points:
```python
from importlib.metadata import entry_points
BACKENDS = {
entry_point.name: entry_point.load()
for entry_point in entry_points(group="waldur_site_agent.backends")
}
```
This enables:
- **Zero-configuration discovery**: Plugins are found automatically when installed
- **Dynamic loading**: Plugin classes are loaded on-demand
- **Flexible deployment**: Different plugin combinations for different environments
- **Third-party integration**: External plugins work seamlessly with the core system
## Configuration integration
Plugins integrate through offering configuration:
```yaml
offerings:
- name: "Example Offering"
backend_type: "slurm" # Legacy setting
order_processing_backend: "slurm" # Order processing via SLURM
reporting_backend: "custom-api" # Custom reporting backend
membership_sync_backend: "slurm" # Membership sync via SLURM
username_management_backend: "custom" # Custom username generation
```
This allows:
- **Mixed backend usage**: Different backends for different operations
- **Gradual migration**: Transition between backends incrementally
- **Specialized backends**: Use purpose-built backends for specific tasks
- **Development flexibility**: Test new backends alongside production ones

### Configuration Validation with Pydantic
# Configuration Validation with Pydantic
The Waldur Site Agent uses Pydantic for robust YAML configuration validation, providing type safety,
clear error messages, and extensible plugin-specific validation.
## Overview
The validation system consists of two layers:
1. **Core Validation**: Universal fields validated by core Pydantic models
2. **Plugin Validation**: Plugin-specific fields validated by plugin-provided schemas
## Core Configuration Validation
### Basic Structure
All configurations are validated using Pydantic models with enum-based validation:
```yaml
sentry_dsn: "https://key@o123.ingest.sentry.io/456" # URL validation
timezone: "UTC"
offerings:
- name: "My SLURM Cluster"
waldur_api_url: "https://waldur.example.com/api/" # URL validation + auto-normalization
waldur_api_token: "your_token_here"
waldur_offering_uuid: "uuid-here"
backend_type: "slurm" # Auto-lowercased
backend_components:
cpu:
measured_unit: "k-Hours" # Required string
accounting_type: "usage" # Enum: "usage" or "limit"
label: "CPU" # Required string
unit_factor: 60000 # Optional float
limit: 1000 # Optional float
```
### Core Validation Features
**Automatic Validation:**
- **Required Fields**: `name`, `waldur_api_url`, `waldur_api_token`, `waldur_offering_uuid`, `backend_type`
- **URL Validation**: `waldur_api_url` must be valid HTTP/HTTPS URL (auto-adds trailing slash)
- **Enum Validation**: `accounting_type` must be "usage" or "limit"
- **Type Conversion**: `backend_type` automatically lowercased
**Optional URL Validation:**
- **Sentry DSN**: Must be valid URL when provided (empty string → `None`)
### AccountingType Enum
The `accounting_type` field uses a validated enum:
```python
from waldur_site_agent.common.structures import AccountingType
# Valid values
AccountingType.USAGE # "usage"
AccountingType.LIMIT # "limit"
```
**Benefits:**
- IDE autocomplete
- Compile-time type checking
- Clear validation errors
- No custom validator code needed
## Plugin-Specific Validation
### How Plugin Schemas Work
Plugins can provide their own Pydantic schemas to validate plugin-specific configuration fields:
1. **Plugin defines schema**: Creates Pydantic models for their specific fields
2. **Entry point registration**: Registers schema via `pyproject.toml`
3. **Automatic discovery**: Core discovers and applies plugin validation
4. **Graceful fallback**: Invalid plugin fields warn but don't break config
### Creating Plugin Schemas
#### Step 1: Create Schema File
Create `schemas.py` in your plugin:
```python
from __future__ import annotations
from enum import Enum
from typing import Optional
from pydantic import ConfigDict, Field, field_validator
from waldur_site_agent.common.plugin_schemas import (
PluginBackendSettingsSchema,
PluginComponentSchema,
)
class MyPeriodType(Enum):
"""Period types for my plugin."""
MONTHLY = "monthly"
QUARTERLY = "quarterly"
ANNUAL = "annual"
class MyComponentSchema(PluginComponentSchema):
"""My plugin-specific component validation."""
model_config = ConfigDict(extra="allow") # Allow core fields
# Plugin-specific fields
my_period_type: Optional[MyPeriodType] = Field(
default=None,
description="Period type for my plugin features"
)
my_custom_ratio: Optional[float] = Field(
default=None,
description="Custom ratio (0.0-1.0)"
)
@field_validator("my_custom_ratio")
@classmethod
def validate_ratio(cls, v: Optional[float]) -> Optional[float]:
"""Validate custom ratio is between 0.0 and 1.0."""
if v is not None and (v < 0.0 or v > 1.0):
msg = "my_custom_ratio must be between 0.0 and 1.0"
raise ValueError(msg)
return v
```
#### Step 2: Register Entry Points
Add to your plugin's `pyproject.toml`:
```toml
[project.entry-points."waldur_site_agent.component_schemas"]
my-plugin = "waldur_site_agent_my_plugin.schemas:MyComponentSchema"
[project.entry-points."waldur_site_agent.backend_settings_schemas"]
my-plugin = "waldur_site_agent_my_plugin.schemas:MyBackendSettingsSchema"
```
#### Step 3: Use in Configuration
Your plugin-specific fields are now validated:
```yaml
offerings:
- name: "My Plugin Offering"
waldur_api_url: "https://waldur.example.com/api/"
waldur_api_token: "token"
waldur_offering_uuid: "uuid"
backend_type: "my-plugin"
backend_components:
cpu:
# Core fields (validated by BackendComponent)
measured_unit: "Hours"
accounting_type: "usage" # AccountingType enum
label: "CPU"
# Plugin fields (validated by MyComponentSchema)
my_period_type: "quarterly" # MyPeriodType enum
my_custom_ratio: 0.25 # 0.0-1.0 validation
```
## Best Practices
### Use ConfigDict for Python 3.9+ Compatibility
**✅ Correct approach:**
```python
from pydantic import ConfigDict
class MySchema(PluginComponentSchema):
model_config = ConfigDict(extra="allow") # Works on all Python versions
```
**❌ Avoid:**
```python
from typing import ClassVar
class MySchema(PluginComponentSchema):
model_config: ClassVar = {"extra": "allow"} # Fails on Python 3.9
```
### Prefer Enums Over String Validation
**✅ Better approach:**
```python
class BackendType(Enum):
SLURM = "slurm"
MUP = "mup"
backend_type: Optional[BackendType] = Field(default=None)
```
**❌ Avoid:**
```python
@field_validator("backend_type")
@classmethod
def validate_backend_type(cls, v):
if v not in {"slurm", "mup"}:
raise ValueError("Invalid backend type")
return v
```
## SLURM Plugin Example
The SLURM plugin demonstrates real-world plugin validation:
```python
class PeriodType(Enum):
MONTHLY = "monthly"
QUARTERLY = "quarterly"
ANNUAL = "annual"
class SlurmComponentSchema(PluginComponentSchema):
model_config = ConfigDict(extra="allow")
period_type: Optional[PeriodType] = Field(default=None)
carryover_enabled: Optional[bool] = Field(default=None)
grace_ratio: Optional[float] = Field(default=None)
```
## Error Handling
### Core Validation Errors (Fatal)
Stop configuration loading with clear error messages:
```text
ValidationError: 2 validation errors for Offering
waldur_api_url
Value error, waldur_api_url must start with http:// or https://
accounting_type
Input should be 'usage' or 'limit'
```
### Plugin Validation Errors (Warnings)
Log warnings but continue with configuration loading:
```text
Warning: Plugin schema validation failed for slurm.cpu: 1 validation error
period_type: Input should be 'monthly', 'quarterly' or 'annual'
```
## Benefits
### Type Safety
- **IDE Support**: Full autocomplete for configuration fields
- **Compile-time Checking**: Catch errors before runtime
- **Clear Documentation**: Field descriptions provide inline help
### Runtime Validation
- **Immediate Feedback**: Configuration errors caught at startup
- **Rich Error Messages**: Pydantic provides detailed validation feedback
- **Graceful Degradation**: Plugin validation warns but doesn't break
### Maintainability
- **Enum-Based**: No custom string validation code needed
- **Extensible**: Plugins add validation without core changes
- **Evidence-Based**: Schemas based on actual plugin requirements
- **Future-Proof**: Easy to add new validation rules
This validation system provides robust configuration management while maintaining clean separation
between core and plugin concerns.

### Configuration Reference
# Configuration Reference
This document provides a complete reference for configuring Waldur Site Agent.
## Configuration File Structure
The agent uses a YAML configuration file (`waldur-site-agent-config.yaml`) with the following structure:
```yaml
sentry_dsn: ""
timezone: "UTC"
offerings:
- name: "Example Offering"
# Offering-specific configuration...
```
## Global Settings
### `sentry_dsn`
- **Type**: String
- **Description**: Data Source Name for Sentry error tracking
- **Default**: Empty (disabled)
- **Example**: `"https://key@sentry.io/project"`
### `elastic_apm_server_url`
- **Type**: String
- **Description**: Elastic APM server URL. When set, enables Elastic APM monitoring with automatic
instrumentation.
- **Default**: Empty (disabled)
- **Example**: `"https://apm-server.example.com:8200"`
### `timezone`
- **Type**: String
- **Description**: Timezone for billing period calculations
- **Default**: System timezone
- **Recommended**: `"UTC"`
- **Examples**: `"UTC"`, `"Europe/Tallinn"`, `"America/New_York"`
**Note**: Important when agent and Waldur are deployed in different timezones to prevent billing period
mismatches at month boundaries.
## Offering Configuration
Each offering in the `offerings` array represents a separate service offering.
### Basic Settings
#### `name`
- **Type**: String
- **Required**: Yes
- **Description**: Human-readable name for the offering
#### `waldur_api_url`
- **Type**: String
- **Required**: Yes
- **Description**: URL of Waldur API endpoint
- **Example**: `"http://localhost:8081/api/"`
#### `waldur_api_token`
- **Type**: String
- **Required**: Yes
- **Description**: Token for Waldur API authentication
- **Permissions**: The token user must have **OFFERING.MANAGER** role on the offering specified by
`waldur_offering_uuid`. This grants the permissions needed for order processing, usage reporting,
membership sync, and event subscriptions.
- **Security**: Keep this secret and secure
#### `verify_ssl`
- **Type**: Boolean
- **Default**: `true`
- **Description**: Whether to verify SSL certificates for Waldur API
#### `waldur_offering_uuid`
- **Type**: String
- **Required**: Yes
- **Description**: UUID of the offering in Waldur
- **Note**: Found in Waldur UI under Integration -> Credentials
### Backend Configuration
#### `backend_type`
- **Type**: String
- **Required**: Yes for legacy configurations
- **Values**: `"slurm"`, `"moab"`, `"mup"`
- **Description**: Type of backend (legacy setting, use specific backend settings instead)
#### Backend Selection
Configure which backends to use for different operations:
```yaml
order_processing_backend: "slurm" # Backend for order processing
membership_sync_backend: "slurm" # Backend for membership syncing
reporting_backend: "slurm" # Backend for usage reporting
username_management_backend: "base" # Backend for username management
```
**Available backends** (via entry points):
- `"slurm"`: SLURM cluster management
- `"moab"`: MOAB cluster management
- `"mup"`: MUP portal integration
- `"waldur"`: Waldur-to-Waldur federation
- `"base"`: Basic username management
- `"rancher"`: Direct Rancher REST API integration (single offering = one cluster)
- `"rancher-kc-crd"`: CRD-driven Rancher + Keycloak management via the
[`rancher-keycloak-operator`](https://github.com/waldur/rancher-keycloak-operator).
Membership-sync only; targets multiple clusters per offering by reading
`cluster_id` from each Resource's `backend_id`. See
[`plugins/rancher-kc-crd/README.md`](../plugins/rancher-kc-crd/README.md).
- Custom backends via plugins
**Note**: If a backend setting is omitted, that process won't start for the offering.
### Event Processing
#### `stomp_enabled`
- **Type**: Boolean
- **Default**: `false`
- **Description**: Enable STOMP-based event processing
#### `stomp_membership_sync_enabled`
- **Type**: Boolean or null
- **Default**: `null` (inherits `stomp_enabled`)
- **Description**: Controls whether membership sync uses STOMP events or HTTP
polling. When `stomp_enabled` is `true` this defaults to `true` as well.
Set to `false` to keep HTTP polling for membership sync while using STOMP for
order processing.
- **Note**: Setting this to `true` while `stomp_enabled` is `false` leaves
membership sync with no runner at all — the polling agent skips it (assuming
STOMP owns it) and the STOMP consumers never start. The agent logs a
`MISCONFIGURATION` warning on startup if it sees this combination.
#### `websocket_use_tls`
- **Type**: Boolean
- **Default**: `true`
- **Description**: Use TLS for websocket connections
### Resource Management
#### `resource_import_enabled`
- **Type**: Boolean
- **Default**: `false`
- **Description**: Whether to expose importable resources to Waldur
## Common Backend Settings
These settings can be used in `backend_settings` for any backend type.
### `check_backend_id_uniqueness`
- **Type**: Boolean
- **Default**: `false`
- **Description**: Enable checking that the generated backend ID is unique
across offering history before creating a resource. When enabled, the agent
queries Waldur to verify uniqueness and retries with a new ID on collision.
### `check_all_offerings`
- **Type**: Boolean
- **Default**: `false`
- **Description**: When `check_backend_id_uniqueness` is enabled, check
uniqueness across all customer offerings instead of only the current offering.
### `backend_id_max_retries`
- **Type**: Integer
- **Default**: `50`
- **Description**: Maximum number of retry attempts when generating a unique
backend ID. Applies when `check_backend_id_uniqueness` is enabled or the
`project_slug` account name generation policy is used. Set to a lower value
if collisions are rare or a higher value for large deployments.
### Account name generation vs. resource slug templates
The offering's `account_name_generation_policy` plugin option (set in Waldur,
not in the agent config) controls how the agent derives a resource's backend ID
(e.g. the SLURM account name):
- **Unset (default)** — the agent uses the resource's slug verbatim:
`{allocation_prefix}{resource_slug}`. If the offering also defines a
`resource_slug_template` (e.g. `{project_slug}-{counter}`), the slug is already
unique and is used as-is, with **no extra suffix**.
- **`project_slug`** — the agent **ignores the resource slug** and instead
derives the backend ID from the *project* slug, appending an incrementing
`-{counter}` on each collision to disambiguate multiple resources in the same
project.
> **Warning:** `account_name_generation_policy: project_slug` and
> `resource_slug_template` are two mutually exclusive ways to make backend IDs
> unique. If you set both, the `project_slug` policy wins and appends its own
> counter on top of (and ignoring) your template — producing IDs like
> `prefix-test-prj-01-2-31`. If you use a `resource_slug_template`, leave
> `account_name_generation_policy` **unset** so the unique slug is used directly.
## Backend-Specific Settings
### SLURM Backend Settings
```yaml
backend_settings:
default_account: "root" # DefaultAccount= on user associations
# root_account: "root" # Parent of top-tier customer account
# default_account_policy: "common" # common (default) | individual | none
customer_prefix: "hpc_" # Prefix for customer accounts
project_prefix: "hpc_" # Prefix for project accounts
allocation_prefix: "hpc_" # Prefix for allocation accounts
qos_downscaled: "limited" # QoS for downscaled accounts
qos_paused: "paused" # QoS for paused accounts
qos_default: "normal" # Default QoS
enable_user_homedir_account_creation: true # Create home directories
default_homedir_umask: "0077" # Umask for home directories
```
### MOAB Backend Settings
```yaml
backend_settings:
default_account: "root"
customer_prefix: "c_"
project_prefix: "p_"
allocation_prefix: "a_"
enable_user_homedir_account_creation: true
```
### MUP Backend Settings
```yaml
backend_settings:
# MUP-specific settings
api_url: "https://mup.example.com/api/"
api_token: "your-api-token"
# Other MUP-specific configuration
```
### Waldur Federation Backend Settings
The `target_api_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). Access to the target
offering's users is granted via ISD overlap, not via OFFERING.MANAGER.
```yaml
backend_settings:
target_api_url: "https://waldur-b.example.com/api/"
target_api_token: "token-for-waldur-b" # customer owner + ISD manager
target_offering_uuid: "offering-uuid-on-waldur-b"
target_customer_uuid: "customer-uuid-on-waldur-b"
user_match_field: "cuid" # cuid | email | username
order_poll_timeout: 300 # Max seconds for sync order completion
order_poll_interval: 5 # Seconds between sync order polls
user_not_found_action: "warn" # warn | fail
identity_bridge_source: "isd:efp" # ISD source for identity bridge
user_resolve_method: "identity_bridge" # identity_bridge | remote_eduteams | user_field
role_mapping: # Optional: translate role names A -> B
PROJECT.ADMIN: PROJECT.ADMIN
PROJECT.MANAGER: PROJECT.MANAGER
end_date_sync_direction: "bidirectional" # a_to_b | b_to_a | bidirectional | disabled
limit_sync_direction: "b_to_a" # b_to_a (default) | disabled -- limit sync
passthrough_attributes: [] # Offering attribute keys forwarded verbatim to B
fetch_consented_users_only: false # Only sync users with data-sharing consent
# Optional: target STOMP for instant async order completion
# Requires target_offering_uuid to be a Marketplace.Slurm offering
target_stomp_enabled: false
```
## Backend Components
Define computing components tracked by the backend:
```yaml
backend_components:
cpu:
measured_unit: "k-Hours" # Waldur measured unit
unit_factor: 60000 # Conversion factor
accounting_type: "usage" # "usage", "limit", or "one"
label: "CPU" # Display label in Waldur
mem:
limit: 10 # Fixed limit amount
measured_unit: "gb-Hours"
unit_factor: 61440 # 60 * 1024
accounting_type: "usage"
label: "RAM"
```
### Component Settings
#### `measured_unit`
- **Type**: String
- **Description**: Unit displayed in Waldur
- **Examples**: `"k-Hours"`, `"gb-Hours"`, `"EUR"`
#### `unit_factor`
- **Type**: Number
- **Description**: Factor for conversion from Waldur units to backend units
- **Examples**:
- `60000` for CPU (60 * 1000, converts k-Hours to CPU-minutes)
- `61440` for memory (60 * 1024, converts gb-Hours to MB-minutes)
#### `accounting_type`
- **Type**: String
- **Values**: `"usage"`, `"limit"`, or `"one"`
- **Description**: Controls billing type and backend behavior.
`"usage"` for usage-based tracking, `"limit"` for fixed
allocation caps, `"one"` for prepaid ONE_TIME billing
(automatically sets `is_prepaid: true` in Waldur).
#### `label`
- **Type**: String
- **Description**: Human-readable label displayed in Waldur
#### `limit`
- **Type**: Number
- **Optional**: Yes
- **Description**: Fixed limit amount for limit-type components
#### `description`
- **Type**: String
- **Optional**: Yes
- **Description**: Description of the component shown in Waldur
#### `min_value`
- **Type**: Integer
- **Optional**: Yes
- **Description**: Minimum allowed value for the component
#### `max_value`
- **Type**: Integer
- **Optional**: Yes
- **Description**: Maximum allowed value for the component
#### `max_available_limit`
- **Type**: Integer
- **Optional**: Yes
- **Description**: Maximum available limit for the component
#### `default_limit`
- **Type**: Integer
- **Optional**: Yes
- **Description**: Default limit value applied when creating a resource
#### `limit_period`
- **Type**: String
- **Optional**: Yes
- **Values**: `"annual"`, `"month"`, `"quarterly"`, `"total"`
- **Description**: Billing period for limit enforcement
#### `article_code`
- **Type**: String
- **Optional**: Yes
- **Description**: Article code for billing system integration
#### `is_boolean`
- **Type**: Boolean
- **Optional**: Yes
- **Description**: Whether the component represents a boolean (on/off) option
#### `is_prepaid`
- **Type**: Boolean
- **Optional**: Yes
- **Description**: Whether the component requires prepaid billing.
Automatically set to `true` when `accounting_type: "one"`.
#### `min_prepaid_duration`
- **Type**: Integer
- **Optional**: Yes
- **Description**: Minimum initial prepaid duration in months. Only applies when `accounting_type: "one"`.
#### `max_prepaid_duration`
- **Type**: Integer
- **Optional**: Yes
- **Description**: Maximum initial prepaid duration in months. Only applies when `accounting_type: "one"`.
#### `prepaid_duration_step`
- **Type**: Integer
- **Optional**: Yes
- **Description**: Step size in months for initial duration.
If set, only multiples of this value
(starting from `min_prepaid_duration`) are valid.
For example, `min_prepaid_duration: 3` and
`prepaid_duration_step: 3` allows 3, 6, 9, 12 months.
#### `min_renewal_duration`
- **Type**: Integer
- **Optional**: Yes
- **Description**: Minimum renewal duration in months.
#### `max_renewal_duration`
- **Type**: Integer
- **Optional**: Yes
- **Description**: Maximum renewal duration in months.
#### `renewal_duration_step`
- **Type**: Integer
- **Optional**: Yes
- **Description**: Step size in months for renewal.
Only multiples of this value
(starting from `min_renewal_duration`) are valid.
### Prepaid Billing
Prepaid billing allows customers to pay upfront for a fixed
capacity over a specified duration.
Prepaid components use `accounting_type: "one"` which maps
to Waldur's ONE_TIME billing type and automatically sets
`is_prepaid: true`.
When a component has `accounting_type: "one"`,
the following flow applies:
1. **Ordering**: Customer orders a resource with limits
and an `end_date`. Waldur validates the duration
against component constraints.
2. **Upfront billing**: Waldur creates a single invoice
item for the full subscription period
(limit × price × months).
3. **Backend enforcement**: The site agent calculates
`GrpTRESMins = limit × duration_months × unit_factor`
and sets it on the SLURM account. This gives SLURM
a cumulative budget cap for the subscription period.
4. **Limit changes**: Customer can request more capacity.
Waldur creates supplementary invoice items.
The agent recalculates GrpTRESMins with the new
limits and remaining duration.
5. **Renewal**: Customer extends the subscription.
The agent detects the new `end_date` and
recalculates GrpTRESMins with the extended duration.
6. **Termination**: When `end_date` is reached,
Waldur automatically creates a TERMINATE order.
### Backend-Specific Component Notes
**SLURM**: Supports `cpu`, `mem`, and other custom components
**MOAB**: Only supports `deposit` component
```yaml
backend_components:
deposit:
measured_unit: "EUR"
accounting_type: "limit"
label: "Deposit (EUR)"
```

### Deployment Guide
# Deployment Guide
This guide covers production deployment of Waldur Site Agent using systemd services.
## Deployment Overview
The agent can run in 4 different modes, deployed as separate systemd services:
1. **agent-order-process**: Processes orders from Waldur
2. **agent-report**: Reports usage data to Waldur
3. **agent-membership-sync**: Synchronizes memberships
4. **agent-event-process**: Event-based processing (alternative to #1 and #3)
## Service Combinations
**Option 1: Polling-based** (traditional)
- agent-order-process
- agent-membership-sync
- agent-report
**Option 2: Event-based** (requires STOMP)
- agent-event-process
- agent-report
**Note**: Only one combination can be active at a time.
## Systemd Service Setup
### Download Service Files
```bash
# Order processing service
sudo curl -L \
https://raw.githubusercontent.com/waldur/waldur-site-agent/main/systemd-conf/agent-order-process/agent.service \
-o /etc/systemd/system/waldur-agent-order-process.service
# Reporting service
sudo curl -L \
https://raw.githubusercontent.com/waldur/waldur-site-agent/main/systemd-conf/agent-report/agent.service \
-o /etc/systemd/system/waldur-agent-report.service
# Membership sync service
sudo curl -L \
https://raw.githubusercontent.com/waldur/waldur-site-agent/main/systemd-conf/agent-membership-sync/agent.service \
-o /etc/systemd/system/waldur-agent-membership-sync.service
# Event processing service
sudo curl -L \
https://raw.githubusercontent.com/waldur/waldur-site-agent/main/systemd-conf/agent-event-process/agent.service \
-o /etc/systemd/system/waldur-agent-event-process.service
```
### Legacy Systemd Support
For systemd versions older than 240:
```bash
# Use legacy service files instead
sudo curl -L \
https://raw.githubusercontent.com/waldur/waldur-site-agent/main/systemd-conf/agent-order-process/agent-legacy.service \
-o /etc/systemd/system/waldur-agent-order-process.service
# Repeat for other services with -legacy.service files
```
### Enable and Start Services
#### Option 1: Polling-based Deployment
```bash
systemctl daemon-reload
# Start and enable services
systemctl start waldur-agent-order-process.service
systemctl enable waldur-agent-order-process.service
systemctl start waldur-agent-report.service
systemctl enable waldur-agent-report.service
systemctl start waldur-agent-membership-sync.service
systemctl enable waldur-agent-membership-sync.service
```
#### Option 2: Event-based Deployment
```bash
systemctl daemon-reload
# Start and enable services
systemctl start waldur-agent-event-process.service
systemctl enable waldur-agent-event-process.service
systemctl start waldur-agent-report.service
systemctl enable waldur-agent-report.service
```
## Service Management
### Check Service Status
```bash
# Check individual service
systemctl status waldur-agent-order-process.service
# Check all waldur services
systemctl status waldur-agent-*
```
### View Logs
```bash
# Follow logs for a service
journalctl -u waldur-agent-order-process.service -f
# View recent logs
journalctl -u waldur-agent-order-process.service --since "1 hour ago"
# View logs for all agents
journalctl -u waldur-agent-* -f
```
### Restart Services
```bash
# Restart individual service
systemctl restart waldur-agent-order-process.service
# Restart all agent services
systemctl restart waldur-agent-*
```
## Configuration Management
### Configuration File Location
The default configuration file location is `/etc/waldur/waldur-site-agent-config.yaml`.
### Update Configuration
1. Edit configuration file:
```bash
sudo nano /etc/waldur/waldur-site-agent-config.yaml
```
2. Validate configuration:
```bash
waldur_site_diagnostics -c /etc/waldur/waldur-site-agent-config.yaml
```
3. Restart services:
```bash
systemctl restart waldur-agent-*
```
## Event-Based Processing Setup
### STOMP Configuration
For STOMP-based event processing:
```yaml
offerings:
- name: "Your Offering"
# ... other settings ...
stomp_enabled: true
websocket_use_tls: true
```
**Important**: Configure the event bus settings in Waldur to match your agent configuration.
## Monitoring and Alerting
### Health Checks
Create a monitoring script:
```bash
#!/bin/bash
# /usr/local/bin/check-waldur-agent.sh
SERVICES=("waldur-agent-order-process" "waldur-agent-report" "waldur-agent-membership-sync")
for service in "${SERVICES[@]}"; do
if ! systemctl is-active --quiet "$service"; then
echo "CRITICAL: $service is not running"
exit 2
fi
done
echo "OK: All Waldur agent services are running"
exit 0
```
### Log Rotation
Systemd handles log rotation automatically via journald. Configure retention:
```bash
# Edit journald configuration
sudo nano /etc/systemd/journald.conf
# Add or modify:
SystemMaxUse=1G
MaxRetentionSec=1month
```
### Sentry Integration
Add Sentry DSN to configuration for error tracking:
```yaml
sentry_dsn: "https://your-dsn@sentry.io/project"
```
Set environment in systemd service files:
```ini
[Service]
Environment=SENTRY_ENVIRONMENT=production
```
## Security Considerations
### File Permissions
```bash
# Secure configuration file
sudo chmod 600 /etc/waldur/waldur-site-agent-config.yaml
sudo chown root:root /etc/waldur/waldur-site-agent-config.yaml
```
### API Token Security
- For the source offering: the token user needs **OFFERING.MANAGER** role on the offering
- For Waldur federation (`waldur` backend): the target token user needs **customer owner**
(can be a non-SP customer) and **ISD identity manager** (`managed_isds` set)
- Use dedicated service accounts in Waldur
- Rotate API tokens regularly
- Store tokens securely (consider using systemd credentials)
### Network Security
- Restrict outbound connections to Waldur API endpoints
- Use TLS for all connections
- Configure firewall rules appropriately
## Troubleshooting
### Common Issues
#### Service Won't Start
1. Check configuration syntax:
```bash
waldur_site_diagnostics -c /etc/waldur/waldur-site-agent-config.yaml
```
2. Check service logs:
```bash
journalctl -u waldur-agent-order-process.service -n 50
```
#### Backend Connection Issues
1. Test backend connectivity:
```bash
# For SLURM
sacct --help
sacctmgr --help
# For MOAB (as root)
mam-list-accounts
```
2. Check permissions and PATH
#### Waldur API Issues
1. Test API connectivity:
```bash
curl -H "Authorization: Token your-token" https://waldur.example.com/api/
```
2. Verify SSL certificates if using HTTPS
### Debug Mode
Enable debug logging by setting `log_level` in the agent configuration file:
```yaml
log_level: DEBUG
```
## Performance Tuning
### Adjust Processing Periods
Modify environment variables in systemd service files:
```ini
[Service]
# Reduce order processing frequency for high-load systems
Environment=WALDUR_SITE_AGENT_ORDER_PROCESS_PERIOD_MINUTES=10
# Increase reporting frequency for better accuracy
Environment=WALDUR_SITE_AGENT_REPORT_PERIOD_MINUTES=15
```
### Resource Limits
Add resource limits to service files:
```ini
[Service]
MemoryLimit=512M
CPUQuota=50%
```
## Backup and Recovery
### Configuration Backup
```bash
# Backup configuration
sudo cp /etc/waldur/waldur-site-agent-config.yaml /etc/waldur/waldur-site-agent-config.yaml.backup
# Version control (optional)
sudo git init /etc/waldur
sudo git add waldur-site-agent-config.yaml
sudo git commit -m "Initial configuration"
```
### Service State
The agent is stateless, but consider backing up:
- Configuration files
- Custom systemd service modifications
- Log files (if needed for auditing)
## Scaling Considerations
### Multiple Backend Support
The agent supports multiple offerings in a single configuration file. Each offering can use different backends:
```yaml
offerings:
- name: "SLURM Cluster A"
order_processing_backend: "slurm"
# ... SLURM-specific settings ...
- name: "MOAB Cluster B"
order_processing_backend: "moab"
# ... MOAB-specific settings ...
```
### High Availability
For HA deployment:
- Run agents on multiple nodes
- Use external load balancer for STOMP connections
- Implement cluster-level monitoring
- Consider using configuration management tools (Ansible, Puppet, etc.)
---
### E2E Testing
# E2E Testing
End-to-end tests validate the site agent against a real Waldur instance
with a SLURM emulator backend. Orders complete synchronously — no remote
cluster or second Waldur instance is needed.
## Architecture

│ │
│ PostgreSQL 16 ─ RabbitMQ (ws:15674) │
│ Waldur API ─ Waldur Celery worker │
└───────────────────────────────────────────┘
```
The Docker stack boots PostgreSQL, RabbitMQ (with `rabbitmq_web_stomp`),
and Waldur Mastermind (API + Celery worker). A demo preset
(`ci/site_agent_e2e.json`) loads 6 users, 3 offerings, plans, components,
and role assignments.
## Test suites
### SLURM E2E tests (`plugins/slurm/tests/e2e/`)
| File | Tests | What it validates |
|------|-------|-------------------|
| `test_e2e_api_optimizations.py` | ~20 | Order lifecycle (create/update/terminate), membership sync, reporting |
| `test_e2e_benchmark.py` | ~10 | API call counts and response sizes; scales to N resources |
| `test_e2e_stomp.py` | 4 | STOMP WebSocket connections, event delivery, order processing with STOMP active |
### Waldur federation E2E tests (`plugins/waldur/tests/e2e/`)
| File | Tests | What it validates |
|------|-------|-------------------|
| `test_e2e_federation.py` | ~10 | Full Waldur A → Waldur B order processing pipeline |
| `test_e2e_username_sync.py` | ~8 | Username reconciliation between federated instances |
| `test_e2e_usage_sync.py` | ~5 | Usage reporting across federation |
| `test_e2e_stomp.py` | ~5 | STOMP event routing for federation |
| `test_e2e_offering_user_pubsub.py` | ~4 | Offering user attribute sync via STOMP |
| `test_e2e_order_rejection.py` | ~3 | Order rejection handling in federation |
## Running locally
### Prerequisites
1. A running Waldur instance with demo data loaded
2. `uv sync --all-packages` (installs core + all plugins + slurm-emulator)
3. A config YAML pointing at your Waldur instance
### Boot the Docker stack (optional — for a fresh local instance)
```bash
docker compose -f ci/docker-compose.e2e.yml up waldur-db-migration
docker compose -f ci/docker-compose.e2e.yml up -d
# Wait for API to be ready
curl -s -o /dev/null -w "%{http_code}" http://localhost:8080/api/
# Should return 401
# Load demo preset
docker compose -f ci/docker-compose.e2e.yml exec waldur-api \
waldur demo_presets load site_agent_e2e --no-cleanup
```
### Create a local config
Copy `ci/e2e-ci-config.yaml` and change the API host from `docker` to
`localhost`:
```yaml
# e2e-local-config.yaml
offerings:
- name: "E2E SLURM Usage"
waldur_api_url: "http://localhost:8080/api/"
waldur_api_token: "e2e0000000000000000000000000token001"
waldur_offering_uuid: "e2ef0000000000000000000000000001"
stomp_enabled: false
# ... rest same as ci/e2e-ci-config.yaml
```
For STOMP tests, create a second config with `stomp_enabled: true` and
STOMP connection settings:
```yaml
# e2e-local-config-stomp.yaml
offerings:
- name: "E2E SLURM STOMP"
waldur_api_url: "http://localhost:8080/api/"
waldur_api_token: "e2e0000000000000000000000000token001"
waldur_offering_uuid: "e2ef0000000000000000000000000001"
stomp_enabled: true
stomp_ws_host: "localhost"
stomp_ws_port: 15674
stomp_ws_path: "/ws"
websocket_use_tls: false
# ... rest same as ci/e2e-ci-config-stomp.yaml
```
### Run the tests
```bash
# REST E2E tests (API optimizations + benchmarks)
WALDUR_E2E_TESTS=true \
WALDUR_E2E_CONFIG=e2e-local-config.yaml \
WALDUR_E2E_PROJECT_A_UUID=e2eb0000000000000000000000000001 \
.venv/bin/python -m pytest plugins/slurm/tests/e2e/ -v \
--ignore=plugins/slurm/tests/e2e/test_e2e_stomp.py
# STOMP E2E tests
WALDUR_E2E_TESTS=true \
WALDUR_E2E_STOMP_CONFIG=e2e-local-config-stomp.yaml \
WALDUR_E2E_PROJECT_A_UUID=e2eb0000000000000000000000000001 \
.venv/bin/python -m pytest plugins/slurm/tests/e2e/test_e2e_stomp.py -v
# Multi-resource benchmark (default N=800, reduce for quick runs)
WALDUR_E2E_TESTS=true \
WALDUR_E2E_CONFIG=e2e-local-config.yaml \
WALDUR_E2E_PROJECT_A_UUID=e2eb0000000000000000000000000001 \
WALDUR_E2E_BENCH_RESOURCES=10 \
.venv/bin/python -m pytest plugins/slurm/tests/e2e/test_e2e_benchmark.py -v -k multi
```
## Environment variables
| Variable | Required | Description |
|----------|----------|-------------|
| `WALDUR_E2E_TESTS` | Yes | Set to `true` to enable E2E tests (skipped otherwise) |
| `WALDUR_E2E_CONFIG` | For REST tests | Path to agent config YAML (`stomp_enabled: false`) |
| `WALDUR_E2E_STOMP_CONFIG` | For STOMP tests | Path to agent config YAML (`stomp_enabled: true`) |
| `WALDUR_E2E_PROJECT_A_UUID` | Yes | Project UUID on Waldur to create orders in |
| `WALDUR_E2E_BENCH_RESOURCES` | No | Number of resources for multi-resource benchmark (default: 800, CI uses 5) |
## CI pipeline
The E2E job runs in the `E2E integration tests` stage in `.gitlab-ci.yml`.
It triggers on pushes to `main` and release tags.
### CI flow
1. Install Docker CLI + Compose plugin (static binaries)
2. `uv sync --all-packages` — install site-agent + slurm-emulator
3. `docker compose -f ci/docker-compose.e2e.yml up` — boot Waldur stack
4. Wait for API health check (`curl http://docker:8080/api/`)
5. Copy and load `site_agent_e2e` demo preset
6. Force-set deterministic auth token
7. **REST E2E tests** — `pytest plugins/slurm/tests/e2e/ --ignore=test_e2e_stomp.py`
8. **STOMP E2E tests** — `pytest plugins/slurm/tests/e2e/test_e2e_stomp.py`
9. Collect JUnit XML reports, stack logs, and markdown reports as artifacts
The REST and STOMP tests run sequentially in the same job to reuse the
~14min Docker stack boot + migration time.
### CI files
| File | Purpose |
|------|---------|
| `ci/docker-compose.e2e.yml` | Minimal Waldur stack: PostgreSQL, RabbitMQ (with web_stomp), API + worker |
| `ci/e2e-ci-config.yaml` | REST test config: 3 offerings (usage/limits/mixed), `stomp_enabled: false` |
| `ci/e2e-ci-config-stomp.yaml` | STOMP test config: 1 offering, `stomp_enabled: true` |
| `ci/site_agent_e2e.json` | Demo preset: 6 users, 3 offerings, plans, components, roles |
| `ci/override.conf.py` | Mastermind Django settings (Celery broker, RabbitMQ STOMP) |
| `ci/rabbitmq-enabled-plugins` | Enables `rabbitmq_management`, `rabbitmq_web_stomp`, `rabbitmq_stomp` |
| `ci/rabbitmq.conf` | RabbitMQ connection and permissions config |
| `ci/createdb-celery_results.sql` | Creates the `celery_results` database for Celery |
### Artifacts
- `e2e-report-rest.xml` / `e2e-report-stomp.xml` — JUnit test results
- `waldur-stack-logs.txt` — Docker stack logs for debugging failures
- `plugins/slurm/tests/e2e/*-report.md` — Detailed markdown reports with API call tables
- `plugins/slurm/tests/e2e/*-report.json` — Machine-readable API call counts
## Test reports
Each test run produces a markdown report and a JSON summary in
`plugins/slurm/tests/e2e/`. The markdown report includes:
- Per-test API call tables (method, URL, status, response size)
- Order/resource state snapshots at each processor cycle
- API call summary table (calls and bytes per test)
These reports are useful for tracking API efficiency across changes.
## Troubleshooting
### Tests are skipped
All E2E tests are gated by `WALDUR_E2E_TESTS=true`. If tests show as
"skipped", check that the environment variable is set.
### "WALDUR_E2E_CONFIG not set" / "WALDUR_E2E_STOMP_CONFIG not set"
REST tests need `WALDUR_E2E_CONFIG`, STOMP tests need
`WALDUR_E2E_STOMP_CONFIG`. They use separate config files because
STOMP tests require `stomp_enabled: true` with WebSocket connection
settings.
### STOMP tests skip with "endpoint not reachable"
The STOMP tests check that RabbitMQ's web_stomp endpoint is accessible
before attempting connections. Verify that:
- RabbitMQ is running with `rabbitmq_web_stomp` plugin enabled
- Port 15674 is exposed and reachable
- The `stomp_ws_host` and `stomp_ws_port` in config match your setup
### Order stuck in non-terminal state
The processor runs up to 10 cycles with 2s delays. With the SLURM
emulator, orders should complete in 1 cycle. If orders are stuck:
- Check Waldur API logs for errors
- Verify the demo preset loaded correctly
- Check that the emulator state file (`/tmp/slurm_emulator_db.json`)
is writable
### CI job times out
The E2E job has a default 1-hour timeout. The Waldur DB migration takes
~14 minutes, REST tests ~2 minutes, STOMP tests ~30 seconds. If the job
times out, check the Docker stack logs artifact for migration issues.

### Backend-Specific Plugin Requirements
#### SLURM Plugin (waldur-site-agent-slurm)
**Required for**: SLURM cluster management
**Additional system requirements**:
```bash
# Install SLURM client tools
sudo dnf install -y slurm slurm-slurmd slurm-slurmctld
# Verify SLURM tools
sacct --help
sacctmgr --help
```
**Configuration**: Set `order_processing_backend: "slurm"` in your config file.
#### MOAB Plugin (waldur-site-agent-moab)
**Required for**: MOAB cluster management
**Additional system requirements**:
```bash
# Install MOAB client tools (adjust based on your MOAB distribution)
# Consult your MOAB documentation for Rocky Linux packages
sudo dnf install -y moab-client
# Verify MOAB tools (requires root access)
sudo mam-list-accounts --help
```
**Configuration**: Set `order_processing_backend: "moab"` in your config file.
#### MUP Plugin (waldur-site-agent-mup)
**Required for**: MUP portal integration
**No additional system requirements** - uses API calls only.
**Configuration**: Set `order_processing_backend: "mup"` in your config file.
#### OpenShift/OKD Plugin (waldur-site-agent-okd)
**Required for**: OpenShift and OKD container platform management
**Additional system requirements**:
```bash
# Install OpenShift CLI tools
sudo dnf install -y origin-clients
# Or install oc client manually
curl -LO https://mirror.openshift.com/pub/openshift-v4/clients/ocp/stable/openshift-client-linux.tar.gz
tar -xzf openshift-client-linux.tar.gz
sudo mv oc /usr/local/bin/
# Verify OpenShift tools
oc version
```
**Configuration**: Set `order_processing_backend: "okd"` in your config file.
#### Harbor Plugin (waldur-site-agent-harbor)
**Required for**: Harbor container registry management
**No additional system requirements** - uses Harbor API calls only.
**Configuration**: Set `order_processing_backend: "harbor"` in your config file.
#### Ceph S3 Plugin (waldur-site-agent-ceph-s3)
**Required for**: Ceph object storage, either croit-managed or a stock cluster
reached through RadosGW Admin Ops.
**No additional system requirements** - uses HTTP API calls only.
**Configuration**: a croit-managed cluster, which is the flavour that can meter:
```yaml
backend_type: "ceph_s3"
order_processing_backend: "ceph_s3"
membership_sync_backend: "ceph_s3"
reporting_backend: "croit_usage" # GB-day metering; a separate backend, croit only
```
Note the underscore: backend names are entry-point names and are matched exactly,
so a hyphenated value resolves to no backend at all. A stock RadosGW cluster runs
the same `ceph_s3` backend under `flavour: "radosgw"` with no `reporting_backend`
— it exposes no equivalent series and cannot be metered.
#### CSCS DWDI Plugin (waldur-site-agent-cscs-dwdi)
**Required for**: CSCS DWDI integration
**No additional system requirements** - uses API calls only.
**Configuration**: Set `order_processing_backend: "cscs-dwdi"` in your config file.

sudo systemctl enable waldur-agent-report.service
sudo systemctl enable waldur-agent-membership-sync.service
sudo systemctl start waldur-agent-order-process.service
sudo systemctl start waldur-agent-report.service
sudo systemctl start waldur-agent-membership-sync.service
```
## Firewall Configuration
Configure firewall if needed:
```bash
# Check if firewall is running
sudo systemctl status firewalld
# Allow outbound HTTPS (if using HTTPS for Waldur API)
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --reload
# For custom ports or STOMP, add specific rules:
# sudo firewall-cmd --permanent --add-port=61613/tcp # STOMP
# sudo firewall-cmd --reload
```
## SELinux Configuration
Rocky 9 has SELinux enabled by default. Configure it for the agent:
```bash
# Check SELinux status
sestatus
# Set proper SELinux contexts
sudo setsebool -P httpd_can_network_connect 1
sudo semanage fcontext -a -t bin_t "/opt/waldur-agent/.local/bin/waldur_site_agent"
sudo restorecon -R /opt/waldur-agent/.local/bin/
# If using custom directories, add contexts:
sudo semanage fcontext -a -t admin_home_t "/opt/waldur-agent(/.*)?"
sudo restorecon -R /opt/waldur-agent/
```
## Verification
### 1. Test Installation
```bash
# Test agent command
sudo -u waldur-agent waldur_site_agent --help
# Test configuration
sudo -u waldur-agent waldur_site_diagnostics -c /etc/waldur/waldur-site-agent-config.yaml
```
### 2. Check Service Status
```bash
# Check all services
sudo systemctl status waldur-agent-*
# Check logs
sudo journalctl -u waldur-agent-order-process.service -f
```
### 3. Test Connectivity
```bash
# Test Waldur API connectivity (replace with your actual URL and token)
curl -H "Authorization: Token YOUR_TOKEN" https://your-waldur.example.com/api/
# Test backend connectivity (for SLURM)
sudo -u waldur-agent sacct --help
```
## Monitoring and Maintenance
### 1. Log Monitoring
```bash
# Monitor all agent logs
sudo journalctl -u waldur-agent-* -f
# Check for errors
sudo journalctl -u waldur-agent-* --since "1 hour ago" | grep -i error
```
### 2. Health Check Script
Create a health check script:
```bash
sudo tee /usr/local/bin/check-waldur-agent.sh << 'EOF'
#!/bin/bash
SERVICES=("waldur-agent-order-process" "waldur-agent-report" "waldur-agent-membership-sync")
FAILED=0
for service in "${SERVICES[@]}"; do
if ! systemctl is-active --quiet "$service"; then
echo "CRITICAL: $service is not running"
FAILED=1
fi
done
if [ $FAILED -eq 0 ]; then
echo "OK: All Waldur agent services are running"
exit 0
else
exit 1
fi
EOF
sudo chmod +x /usr/local/bin/check-waldur-agent.sh
# Test the script
/usr/local/bin/check-waldur-agent.sh
```
### 3. Automatic Updates
Set up automatic security updates:
```bash
# Install dnf-automatic
sudo dnf install -y dnf-automatic
# Configure for security updates only
sudo sed -i 's/apply_updates = no/apply_updates = yes/' /etc/dnf/automatic.conf
sudo sed -i 's/upgrade_type = default/upgrade_type = security/' /etc/dnf/automatic.conf
# Enable the service
sudo systemctl enable --now dnf-automatic.timer
```
## Troubleshooting
### Common Issues
#### Permission Denied Errors
```bash
# Check file ownership
ls -la /etc/waldur/
ls -la /opt/waldur-agent/.local/bin/
# Fix ownership if needed
sudo chown -R waldur-agent:waldur-agent /opt/waldur-agent/
```
#### SELinux Denials
```bash
# Check for denials
sudo sealert -a /var/log/audit/audit.log
# Generate policy if needed
sudo ausearch -c 'waldur_site_age' --raw | audit2allow -M my-waldur-agent
sudo semodule -i my-waldur-agent.pp
```
#### Network Connectivity
```bash
# Test DNS resolution
nslookup your-waldur.example.com
# Test firewall
sudo firewall-cmd --list-all
# Test with curl
curl -v https://your-waldur.example.com/api/
```
#### Service Startup Issues
```bash
# Check service status
sudo systemctl status waldur-agent-order-process.service -l
# Check journal logs
sudo journalctl -u waldur-agent-order-process.service --no-pager
```
## Security Hardening
### 1. Secure Configuration File
```bash
# Set restrictive permissions
sudo chmod 600 /etc/waldur/waldur-site-agent-config.yaml
sudo chown waldur-agent:waldur-agent /etc/waldur/waldur-site-agent-config.yaml
```
### 2. Limit User Privileges
```bash
# Ensure waldur-agent user has minimal privileges
sudo usermod -s /usr/sbin/nologin waldur-agent # Disable shell login
```
### 3. Network Security
```bash
# Restrict outbound connections (adjust as needed)
# Allow outbound HTTPS to Waldur API
sudo firewall-cmd --permanent --direct --add-rule ipv4 filter OUTPUT 0 \
-m owner --uid-owner $(id -u waldur-agent) \
-d your-waldur.example.com -p tcp --dport 443 -j ACCEPT
# Block all other outbound traffic for waldur-agent user
sudo firewall-cmd --permanent --direct --add-rule ipv4 filter OUTPUT 1 \
-m owner --uid-owner $(id -u waldur-agent) -j DROP
sudo firewall-cmd --reload
```
This completes the Rocky Linux 9 specific installation guide. The next step would be to test these
instructions on the actual system.

## Firewall Configuration
Ubuntu 24.04 uses UFW (Uncomplicated Firewall):
```bash
# Check firewall status
sudo ufw status
# If UFW is active, allow outbound HTTPS (usually allowed by default)
sudo ufw allow out 443/tcp
# For custom ports or STOMP, add specific rules:
# sudo ufw allow out 61613/tcp # STOMP
```
## AppArmor Configuration (if enabled)
Ubuntu 24.04 may have AppArmor enabled:
```bash
# Check AppArmor status
sudo aa-status
# If needed, create AppArmor profile for the agent
# This is typically not required for standard installations
```

### Offering Users and Async User Creation
# Offering Users and Async User Creation
The Waldur Site Agent provides robust support for managing offering users with asynchronous username generation and
state management. This system enables non-blocking user processing and supports complex username generation scenarios
through a pluggable backend architecture.
## Overview
Offering users represent the relationship between Waldur users and marketplace offerings. The agent handles username
generation, state transitions, and integration with backend systems to ensure users can access provisioned resources.
## Async User Creation Workflow
### State Machine
The async user creation follows a state-based workflow that prevents blocking operations:
```mermaid
stateDiagram-v2
[*] --> REQUESTED : User requests access
REQUESTED --> CREATING : begin_creating
CREATING --> OK : Username set (auto-transition)
CREATING --> PENDING_ACCOUNT_LINKING : Linking required
CREATING --> PENDING_ADDITIONAL_VALIDATION : Validation needed
CREATING --> ERROR_CREATING : BackendError
ERROR_CREATING --> CREATING : begin_creating (retry)
ERROR_CREATING --> PENDING_ACCOUNT_LINKING : Linking required
ERROR_CREATING --> PENDING_ADDITIONAL_VALIDATION : Validation needed
PENDING_ACCOUNT_LINKING --> OK : set_validation_complete
PENDING_ADDITIONAL_VALIDATION --> OK : set_validation_complete
PENDING_ACCOUNT_LINKING --> PENDING_ADDITIONAL_VALIDATION : Cross-transition
PENDING_ADDITIONAL_VALIDATION --> PENDING_ACCOUNT_LINKING : Cross-transition
OK --> [*] : User ready for resource access
```
### State Descriptions
- **REQUESTED**: Initial state when user requests access to an offering
- **CREATING**: Transitional state during username generation process
- **OK**: Username successfully generated and user is ready for resource access
- **PENDING_ACCOUNT_LINKING**: Manual intervention required to link user accounts
- **PENDING_ADDITIONAL_VALIDATION**: Additional validation steps needed before proceeding
- **ERROR_CREATING**: Backend failure during username generation; retried on next sync cycle
## Core Components
### Main Functions
#### `sync_offering_users()`
Entry point function that processes all offering users across configured offerings.
**Usage**:
```bash
uv run waldur_sync_offering_users -c config.yaml
```
**Behavior**:
- Iterates through all configured offerings
- Retrieves offering users from Waldur API
- Delegates processing to `update_offering_users()`
#### `update_offering_users()`
Core processing function that handles username generation and state transitions.
**Process**:
1. Early validation checks (empty users list, username generation policy)
2. Username management backend validation (skips if UnknownUsernameManagementBackend)
3. Efficient user grouping by state (single pass through users)
4. Processes users in REQUESTED state via `_process_requested_users()`
5. Handles users in pending states via `_process_pending_users()`
6. Manages state transitions and centralized error handling
**New Architecture**: The function has been refactored into focused sub-functions:
- `_can_generate_usernames()`: Policy validation
- `_group_users_by_state()`: Efficient user categorization
- `_process_requested_users()`: Handle new username requests
- `_process_pending_users()`: Process retry scenarios
- `_update_user_username()`: Individual user processing
- `_handle_account_linking_error()`: Account linking error management
- `_handle_validation_error()`: Validation error management
- `_set_error_creating()`: Marks user as ERROR_CREATING after backend failures
### Username Management Backend System
The agent uses a pluggable backend architecture for username generation, allowing custom implementations for different
identity providers and naming conventions.
#### Backend Validation
The system now includes early validation to skip processing when no valid username management backend is available:
- **UnknownUsernameManagementBackend**: Fallback backend that returns empty usernames
- **Early Exit**: Processing is skipped if `UnknownUsernameManagementBackend` is detected
- **Performance Optimization**: Prevents unnecessary API calls when username generation isn't possible
#### Base Abstract Class
```python
from waldur_site_agent.backend.backends import AbstractUsernameManagementBackend
class CustomUsernameBackend(AbstractUsernameManagementBackend):
def generate_username(self, offering_user: OfferingUser) -> str:
"""Generate new username based on offering user details."""
# Custom logic here
return generated_username
def get_username(self, offering_user: OfferingUser) -> Optional[str]:
"""Retrieve existing username from local identity provider."""
# Custom lookup logic here
return existing_username
def get_or_create_username(self, offering_user: OfferingUser) -> Optional[str]:
"""Get existing username or create new one if not found."""
username = self.get_username(offering_user)
if not username:
username = self.generate_username(offering_user)
return username
```
#### Plugin Registration
Register your backend via entry points in `pyproject.toml`:
```toml
[project.entry-points."waldur_site_agent.username_management_backends"]
custom_backend = "my_package.backend:CustomUsernameBackend"
```
#### Built-in Backends
- **base**: Basic username management backend (plugins/basic_username_management/)
- **UnknownUsernameManagementBackend**: Fallback backend when configuration is missing or invalid
- Returns empty usernames for all requests
- Triggers early exit from processing to improve performance
- Used automatically when `username_management_backend` is not properly configured
## Configuration
### Offering Configuration
Configure username management per offering in your agent configuration:
```yaml
offerings:
- name: "SLURM Cluster"
waldur_api_url: "https://waldur.example.com/api/"
waldur_api_token: "your-token"
waldur_offering_uuid: "offering-uuid"
backend_type: "slurm"
username_management_backend: "custom_backend" # References entry point name
backend_settings:
# ... other settings
```
### Prerequisites
1. **Service Provider Username Generation**: The offering must be configured
with `username_generation_policy = SERVICE_PROVIDER` in Waldur
2. **Backend Plugin**: Appropriate username management backend must be installed and configured
3. **Permissions**: API token user must have **OFFERING.MANAGER** role on the offering
(grants permissions to manage offering users, orders, and agent identities)
## Integration with Order Processing
The async user creation system is seamlessly integrated with the agent's order processing workflows:
### Automatic Processing
Username generation is automatically triggered during:
- Resource creation orders
- User addition to existing resources
- Membership synchronization operations
### Implementation in Processors
The `OfferingBaseProcessor` class provides `_update_offering_users()` method that:
1. Calls username generation for users with blank usernames
2. Refreshes offering user data after processing
3. Filters users to only include those with valid usernames for resource operations
**Example usage in order processing**:
```python
# Optimized processing with conditional refresh
offering_users = user_context["offering_users"]
# Only refresh if username generation actually occurred
if self._update_offering_users(offering_users):
# Refresh local user_context cache
user_context_new = self._fetch_user_context_for_resource(waldur_resource.uuid.hex)
user_context.update(user_context_new)
# Use only users with valid usernames
valid_usernames = {
user.username for user in user_context["offering_users"]
if user.state == OfferingUserState.OK and user.username
}
```
**Performance Improvements**:
- Conditional refresh only when usernames are actually updated
- Early validation prevents unnecessary processing
- Efficient user state grouping reduces multiple iterations
- Backend validation prevents wasted API calls
## Error Handling
### Exception Types
The system defines specific exceptions for different error scenarios:
- **`OfferingUserAccountLinkingRequiredError`**: Raised when manual account linking is required
- **`OfferingUserAdditionalValidationRequiredError`**: Raised when additional validation steps are needed
- **`BackendError`**: Generic backend failure; triggers ERROR_CREATING state transition
- **Other exceptions** (e.g. `ValueError`, `HTTPError`): Logged but do **not** trigger any state
transition — the user silently stays in their current state. Plugin developers should wrap backend
failures as `BackendError` to ensure the error state is reflected in Waldur.
Both linking/validation exceptions support an optional `comment_url` parameter to provide links to
forms, documentation, or other resources needed for error resolution.
### Error Recovery
When exceptions occur during username generation:
1. User state transitions to appropriate pending or error state
2. Error details are logged with context
3. Comment field is updated with error message and comment_url field with any provided URL
4. Processing continues for other users
5. Pending and error users are retried in subsequent runs
**State transition handling by current user state:**
- **REQUESTED → CREATING**: The agent first transitions the user to CREATING, then calls the backend.
If the backend raises a linking/validation error, the user transitions to the appropriate PENDING state.
If a `BackendError` occurs, the user transitions to ERROR_CREATING.
- **CREATING / ERROR_CREATING**: If the backend raises `OfferingUserAccountLinkingRequiredError` or
`OfferingUserAdditionalValidationRequiredError`, the user transitions to `PENDING_ACCOUNT_LINKING`
or `PENDING_ADDITIONAL_VALIDATION` respectively. If a `BackendError` occurs, the user transitions
to ERROR_CREATING so that admins can see the failure. On the next cycle, ERROR_CREATING users
are moved back to CREATING via `begin_creating` and retried.
- **PENDING_ACCOUNT_LINKING**: If the backend still raises `OfferingUserAccountLinkingRequiredError`,
the user stays in the current state (no redundant API call). If the backend raises
`OfferingUserAdditionalValidationRequiredError`, the user cross-transitions to
PENDING_ADDITIONAL_VALIDATION.
- **PENDING_ADDITIONAL_VALIDATION**: If the backend still raises
`OfferingUserAdditionalValidationRequiredError`, the user stays in the current state.
If the backend raises `OfferingUserAccountLinkingRequiredError`, the user cross-transitions
to PENDING_ACCOUNT_LINKING.
- **PENDING_* → OK**: When username generation succeeds for a PENDING user, `set_validation_complete`
is called (which clears service provider comments) before setting the username.
## Username Reconciliation in Event Processing Mode
When the agent runs in `event_process` mode, offering user username synchronization is primarily driven
by real-time STOMP events. However, transient STOMP disconnections or message loss can cause missed
updates. To address this, the main event loop includes a periodic reconciliation timer.
### How it works
- **Interval**: Defaults to 60 minutes, configurable via `WALDUR_SITE_AGENT_RECONCILIATION_PERIOD_MINUTES`
- **Scope**: Only runs for offerings with both `stomp_enabled: true` and a `membership_sync_backend`
- **Operation**: Calls `sync_offering_user_usernames()` which compares usernames between source and
target offerings and patches any mismatches
- **Idempotent**: Safe to run at any frequency — no side effects when data is already consistent
- **Lightweight**: Only syncs usernames, not a full membership reconciliation
### Reconciliation interval setting
```yaml
# Environment variable (default: 60 minutes)
WALDUR_SITE_AGENT_RECONCILIATION_PERIOD_MINUTES=60
```
## User Attribute Forwarding
During membership synchronization, the processor can forward user profile
attributes to backends that need them (e.g., the Waldur federation backend
sends attributes to the Identity Bridge API when resolving remote users).
### Attribute resolution flow
Which attributes are forwarded is driven by the offering's
`OfferingUserAttributeConfig`. Providers configure which user fields are
*exposed* via the Waldur admin UI (e.g., `expose_email`, `expose_organization`,
`expose_gender`). The agent:
1. Fetches the attribute config from the API (cached for 5 minutes).
2. Requests only the exposed fields when listing offering users.
3. During user sync, extracts exposed attribute values from each
`OfferingUser` and passes them to the backend via `user_attributes`.
### Supported attributes
All 20+ attributes from `OfferingUserAttributeConfig` are supported:
`username`, `full_name` (includes `first_name`, `last_name`), `email`,
`phone_number`, `organization`, `job_title`, `affiliations`, `gender`,
`personal_title`, `place_of_birth`, `country_of_residence`, `nationality`,
`nationalities`, `organization_country`, `organization_type`,
`organization_registry_code`, `eduperson_assurance`, `civil_number`,
`birth_date`, `identity_source`, `active_isds`.
### Fallback behavior
When the attribute config API is unavailable, the agent defaults to
exposing `username`, `full_name`, and `email`.
## Best Practices
### Username Backend Implementation
1. **Idempotent Operations**: Ensure `get_or_create_username()` can be called multiple times safely
2. **Error Handling**: Raise appropriate exceptions for recoverable errors
3. **Logging**: Include detailed logging for troubleshooting
4. **Validation**: Validate generated usernames meet backend system requirements
5. **Performance Considerations**: Implement efficient lookup mechanisms to avoid blocking operations
6. **Backend Validation**: Return empty strings when username generation is not supported
### Deployment Considerations
1. **Regular Sync**: Run `waldur_sync_offering_users` regularly via cron or systemd timer
2. **Monitoring**: Monitor pending user states for manual intervention needs
3. **Backup Strategy**: Consider username mapping backup for disaster recovery
4. **Testing**: Test username generation logic thoroughly before production deployment
5. **Backend Configuration**: Ensure proper
`username_management_backend` configuration to avoid
UnknownUsernameManagementBackend fallback
6. **Performance Tuning**: Monitor processing times and adjust batch sizes if needed
7. **Error Recovery**: Set up alerting for persistent pending states that may require manual intervention
## Troubleshooting
### Diagnostic Commands
```bash
# Check system health
uv run waldur_site_diagnostics -c config.yaml
# Manual user sync
uv run waldur_sync_offering_users -c config.yaml
# Check offering user states via API
curl -H "Authorization: Token YOUR_TOKEN" \
"https://waldur.example.com/api/marketplace-offering-users/?offering_uuid=OFFERING_UUID"
```

### Plugin Development Guide
# Plugin Development Guide
This guide covers everything needed to build a custom backend plugin for
Waldur Site Agent. It is written for both human developers and LLM-based
code generators.
## Waldur Mastermind concepts
Before implementing a plugin, understand how Waldur Mastermind concepts
map to plugin operations.
| Waldur concept | Description | Plugin relevance |
|---|---|---|
| **Offering** | Service catalog entry | Config block per offering; picks backend plugin |
| **Resource** | Allocation from an offering | CRUD via `BaseBackend`; keyed by `backend_id` |
| **Order** | Create/update/terminate request | Triggers `order_process` mode |
| **Component** | Measurable dimension (CPU, RAM) | Defined in `backend_components` config |
| **OfferingUser** | User linked to an offering | Username backend generates usernames |
| **billing_type** | `usage` or `limit` | Metered vs quota accounting |
| **backend_id** | Resource ID on the backend | Generated by `_get_resource_backend_id` |
## Architecture overview
A resource-management plugin consists of two main classes:
- **Backend** (inherits `BaseBackend`): Orchestrates high-level operations
(create resource, collect usage, manage users).
- **Client** (inherits `BaseClient`): Handles low-level communication with
the external system (CLI commands, API calls).
A separate plugin family covers username management
(`AbstractUsernameManagementBackend`) — see the dedicated section below.
A single distribution may register both, but the entry point groups are
distinct.

| `check_pending_order` | Returns `True` | Non-blocking order creation (see below) |
| `evaluate_pending_order` | Returns `ACCEPT` | Custom approval logic for pending orders (see below) |
| `setup_target_event_subscriptions` | Returns `[]` | STOMP subscriptions to target systems |
| `get_usage_report_for_period` | Returns `{}` | Historical usage queries for past billing periods |

| `sync_resource_end_date` | No-op | Synchronise `end_date` between source and target Waldur instances |
| `sync_resource_effective_id` | No-op | Reflect downstream `backend_id` as `effective_id` on the source resource |
| `sync_resource_project` | No-op | Push project metadata to backends that manage their own projects |

| `create_user_homedirs` | Provided | Override only to customise homedir quota or path logic |
### Non-blocking order creation (optional)
Backends that create resources via remote APIs can use non-blocking order
creation. Instead of blocking until the remote operation completes, the backend
returns immediately with a `pending_order_id` in `BackendResourceInfo`.
To opt in, set the `supports_async_orders` class attribute to `True`. The
processor only inspects `order.backend_id` for async tracking when this flag
is enabled, which prevents conflicts with external systems (e.g. SharePoint)
that may set `order.backend_id` for unrelated purposes.
```python
class MyAsyncBackend(BaseBackend):
supports_async_orders = True
```
When enabled, the core processor:
1. Sets the source order's `backend_id` to the `pending_order_id`
2. Keeps the order in `EXECUTING` state
3. On subsequent polling cycles, calls `check_pending_order(backend_id)` to check completion
4. When `check_pending_order()` returns `True`, marks the source order as `DONE`
Backends that opt in will typically also override `handled_resource_states`
to include `ResourceState.CREATING` so that user/limit sync runs while the
remote order is still in flight.
#### `check_pending_order(order_backend_id: str) -> bool`
- **Default**: Returns `True` (no async orders, always "complete")
- **Override when**: Your backend uses non-blocking resource creation
- **Returns**: `True` if the remote order completed, `False` if still pending
- **Raises**: `BackendError` if the remote order failed or was cancelled
Example (Waldur federation plugin):
```python
def check_pending_order(self, order_backend_id: str) -> bool:
target_order = self.client.get_order(UUID(order_backend_id))
if target_order.state == OrderState.DONE:
return True
if target_order.state in {OrderState.ERRED, OrderState.CANCELED}:
raise BackendError(f"Target order failed: {target_order.state}")
return False # Still pending
```
#### `setup_target_event_subscriptions(source_offering, user_agent, global_proxy) -> list`
- **Default**: Returns `[]` (no target subscriptions)
- **Override when**: Your backend supports STOMP events from a target system
- **Returns**: List of `StompConsumer` tuples for lifecycle management
- **Called by**: `event_process` mode during STOMP setup
### Pending order evaluation (optional)
When an order arrives in `PENDING_PROVIDER` state, the agent calls
`evaluate_pending_order` on the backend before taking any action. The
default implementation returns `ACCEPT`, which preserves the existing
auto-approve behaviour. Override this method to implement custom
approval logic.
#### `evaluate_pending_order(order, waldur_rest_client) -> PendingOrderDecision`
- **Default**: Returns `PendingOrderDecision.ACCEPT`
- **Override when**: You need to inspect or gate orders before approval
- **Parameters**:
- `order` (`OrderDetails`) — full order data including `project_uuid`,
`customer_uuid`, `created_by_*`, `attributes`, and
`consumer_message` / `provider_message` fields.
- `waldur_rest_client` (`AuthenticatedClient`) — authenticated client
for fetching additional data from the Waldur API (e.g., project
members and roles).
- **Returns** one of:
- `PendingOrderDecision.ACCEPT` — approve the order
- `PendingOrderDecision.REJECT` — reject the order
- `PendingOrderDecision.PENDING` — keep waiting; the order will be
re-evaluated on the next polling cycle
> **Note:** This is the only hook that receives `waldur_rest_client`.
> Other backend methods receive Waldur data via `user_context` instead.
#### Use cases
| Scenario | Approach |
|---|---|
| Wait for a PI | Query project members, return `PENDING` until a PI role exists |
| Reject unprocessable orders | Inspect `order.attributes`, return `REJECT` |
| Require a signed agreement | Set `provider_message`, return `PENDING` until `consumer_message` is set |
#### Example: wait for a PI before approving
```python
from waldur_api_client.api.marketplace_provider_resources import (
marketplace_provider_resources_team_list,
)
from waldur_site_agent.backend.backends import BaseBackend, PendingOrderDecision
class MyBackend(BaseBackend):
def evaluate_pending_order(self, order, waldur_rest_client):
team = marketplace_provider_resources_team_list.sync(
client=waldur_rest_client,
uuid=order.marketplace_resource_uuid.hex,
)
has_pi = any(
member.role_name == "PI" for member in (team or [])
)
if not has_pi:
return PendingOrderDecision.PENDING
return PendingOrderDecision.ACCEPT
```
#### Example: reject orders that lack a required attribute
```python
from waldur_site_agent.backend.backends import BaseBackend, PendingOrderDecision
class MyBackend(BaseBackend):
def evaluate_pending_order(self, order, waldur_rest_client):
attrs = getattr(order, "attributes", None) or {}
if not attrs.get("project_justification"):
return PendingOrderDecision.REJECT
return PendingOrderDecision.ACCEPT
```
## Username management backends
Username management is handled by a separate plugin family inheriting
from `AbstractUsernameManagementBackend` (defined in
`waldur_site_agent/backend/backends.py`). These backends generate or look
up local-IDP usernames for `OfferingUser` records and are wired in the
config via `username_management_backend`.
### Required methods
| Method | Purpose |
|---|---|
| `generate_username(offering_user) -> str` | Create a new local username. Return `""` if generation is not supported. |
| `get_username(offering_user) -> Optional[str]` | Look up the existing local username for the user, or `None`. |
`get_or_create_username` is provided by the base class and calls
`get_username` first, then `generate_username` only if no username is
found.
### Optional hook methods
| Method | Default | When to override |
|---|---|---|
| `sync_user_profiles(offering_users)` | No-op | Push user profiles to the IDP before membership sync runs |
| `deactivate_users(usernames)` | No-op | Remove departed users from the external system |
### Error signalling for user-action gates
When username generation requires the user to take an action (e.g. link
an existing IdP account, complete a validation form), raise one of these
exceptions from `waldur_site_agent.backend.exceptions`:
- `OfferingUserAccountLinkingRequiredError(comment, comment_url=None)` —
user must link an existing account.
- `OfferingUserAdditionalValidationRequiredError(comment, comment_url=None)` —
additional validation is required.
The processor moves the offering user into a `PENDING_ACCOUNT_LINKING` /
`PENDING_ADDITIONAL_VALIDATION` state and surfaces the comment (and URL)
to the operator. See `docs/offering-users.md` for the full state machine.
### Entry point group
Register username management plugins under a different entry point group
than resource backends:
```toml
[project.entry-points."waldur_site_agent.username_management_backends"]
mycustom = "waldur_site_agent_mycustom.username_backend:MyCustomUsernameBackend"
```
The fallback entry point name is `base`, provided by the
`waldur-site-agent-basic-username-management` plugin.
## BaseClient method reference
All methods below are abstract and must be implemented.
| Method | Signature | Purpose |
|---|---|---|
| `list_resources` | `() -> list[ClientResource]` | List all resources on backend |
| `get_resource` | `(resource_id) -> ClientResource or None` | Get single resource or None |
| `create_resource` | `(name, description, organization, parent_name=None) -> str` | Create resource |
| `delete_resource` | `(name) -> str` | Delete resource |
| `set_resource_limits` | `(resource_id, limits_dict) -> str or None` | Set limits (backend units) |
| `get_resource_limits` | `(resource_id) -> dict[str, int]` | Get limits (backend units) |
| `get_resource_user_limits` | `(resource_id) -> dict[str, dict[str, int]]` | Per-user limits |
| `set_resource_user_limits` | `(resource_id, username, limits_dict) -> str` | Set per-user limits |
| `get_association` | `(user, resource_id) -> Association or None` | Check user-resource link |
| `create_association` | `(username, resource_id, default_account=None) -> str` | Create user-resource link |
| `delete_association` | `(username, resource_id) -> str` | Remove user-resource link |
| `get_usage_report` | `(resource_ids, timezone=None) -> list` | Raw usage data from backend |
| `list_resource_users` | `(resource_id) -> list[str]` | List usernames for resource |
**Important**: `BaseClient` also provides:
- `execute_command(command, silent=False)` for running CLI commands with
error handling — use it for CLI-based backends.
- `create_linux_user_homedir(username, umask="")` which shells out to
`/sbin/mkhomedir_helper`. Override only if your backend creates home
directories some other way; otherwise it works as-is for SLURM-style
Linux deployments.

## Usage report format specification
The `_get_usage_report` method must return data in this exact structure:
```python
{
"": {
"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`.
## Capability flags and class attributes
`BaseBackend` exposes three class-level capability flags that change how
the core processor treats your backend.
### `supports_decreasing_usage: bool = False`
Set to `True` 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.
### `supports_cycle_preflight: bool = False`
Set to `True` for backends that call a remote API during order processing.
The order processor runs `run_preflight()` once per offering per cycle
before listing orders. The default implementation calls `ping()` and raises
`BackendNotReadyError` on failure so orders stay pending instead of ERRED.
Override `run_preflight()` to probe specific endpoints. Opt in from plugins
such as Waldur federation and other HTTP backends can enable it when needed.
### `supports_async_orders: bool = False`
Set to `True` for backends that complete order creation asynchronously
on a remote system and report progress via `pending_order_id`. See the
"Non-blocking order creation" section above for the full flow.
```python
class MyAsyncBackend(BaseBackend):
supports_async_orders = True
```
### `handled_resource_states: list = [ResourceState.OK, ResourceState.ERRED]`
Controls which resource states the membership processor fetches and
processes. Override when your backend needs to manage users on resources
that are still being provisioned (e.g., async backends that include
`CREATING`).
```python
from waldur_api_client.models.resource_state import ResourceState
class MyAsyncBackend(BaseBackend):
handled_resource_states = [ResourceState.OK, ResourceState.ERRED, ResourceState.CREATING]
```
### `team_fetch_attempts: int = 1` and `team_fetch_delay: float = 3.0`
Control retry behaviour when `_fetch_user_context_for_resource` gets back
an empty team list. The retry only fires on a completely empty response —
it covers the race where a create-order event arrives before Waldur has
committed the first membership row to the database.
The default of `1` (no retries) is correct for synchronous backends where
the Waldur API is always consistent by the time the agent reads it. Raise
`team_fetch_attempts` for backends that receive work over STOMP, where the
event and the membership row may arrive out of order:
```python
class MyStompBackend(BaseBackend):
team_fetch_attempts = 4 # retry up to 4 times
team_fetch_delay = 3.0 # seconds between retries
```
These are **backend class attributes**, not YAML configuration keys. They
cannot be set per-offering in the configuration file.
## 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 |

```
### `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: register a username management backend
[project.entry-points."waldur_site_agent.username_management_backends"]
mycustom = "waldur_site_agent_mycustom.username_backend:MyCustomUsernameBackend"
# 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`, `order_processing_backend`, or
`username_management_backend` in the config YAML. The four entry-point
groups are independent — a single distribution may register some or all
of them.
## 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

```
### 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. Resource backends use
`"waldur_site_agent.backends"`; username management uses
`"waldur_site_agent.username_management_backends"` (note the plural and
the suffix). Validation schemas use
`"waldur_site_agent.component_schemas"` /
`"waldur_site_agent.backend_settings_schemas"`.
- 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")))
print(list(entry_points(group="waldur_site_agent.username_management_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

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 `uvx prek run --all-files`.
### Files to study
- `waldur_site_agent/backend/backends.py` — `BaseBackend` (resource
backends) and `AbstractUsernameManagementBackend` (username plugins),
plus `PendingOrderDecision` enum.
- `waldur_site_agent/backend/clients.py` — Base client class.
- `waldur_site_agent/backend/structures.py` — Data structures
(`ClientResource`, `Association`, `BackendResourceInfo` with fields
`backend_id`, `parent_id`, `effective_id`, `users`, `usage`, `limits`,
`pending_order_id`, `backend_metadata`).
- `waldur_site_agent/backend/exceptions.py` — `BackendError`,
`DuplicateResourceError`, and the
`OfferingUser*RequiredError` exceptions used by username backends.
- `waldur_site_agent/common/plugin_schemas.py` — `PluginComponentSchema`
and `PluginBackendSettingsSchema` base classes for optional config
validation entry points.
- `plugins/slurm/waldur_site_agent_slurm/backend.py` — Reference
implementation (CLI-based).
- `plugins/mup/waldur_site_agent_mup/backend.py` — Reference
implementation (API-based).
- `plugins/waldur/waldur_site_agent_waldur/backend.py` — Reference for
`supports_async_orders`, `handled_resource_states`, and the
`sync_resource_*` hooks.
- `plugins/basic_username_management/` — Minimal reference for
`AbstractUsernameManagementBackend`.
### 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.

#### System Update Process
- `sudo dnf update -y` initiated successfully
- Process began updating 280 packages including kernel 5.14.0-570.58.1.el9_6
- Large updates including linux-firmware (658 MB) and other system components
#### Development Tools Installation
- `dnf groupinstall "Development Tools"` started successfully
- Installation included essential packages:
- gcc, gcc-c++, make, git, autoconf, automake
- binutils, bison, flex, libtool, etc.
### ⚠️ Interrupted Steps
#### Connection Lost
- Server became unreachable during package installation
- SSH connection refused (port 22)
- Likely system reboot during kernel update process
## Identified Requirements for Rocky 9
Based on initial testing and system analysis:
### System Dependencies
1. **EPEL Repository** - Required for additional packages
```bash
sudo dnf install -y epel-release
```
2. **Development Tools Group** - Essential for building Python packages
```bash
sudo dnf groupinstall "Development Tools" -y
```
3. **System Libraries** - Required for waldur-site-agent dependencies
```bash
sudo dnf install -y openssl-devel libffi-devel bzip2-devel sqlite-devel
```
### Python 3.11 Installation
Rocky 9 ships with Python 3.9 by default. For optimal compatibility:
```bash
# Install from EPEL repository
sudo dnf install -y python3.11 python3.11-pip python3.11-devel
```
### Security Considerations
1. **SELinux** - Enabled by default, requires proper contexts
2. **Firewalld** - Active, needs configuration for API endpoints
3. **Service User** - Dedicated user recommended for security
### Service Management
1. **Systemd** - Version supports required features
2. **Journal Logging** - Available for log management
3. **Service Dependencies** - Standard systemd unit files compatible
## Recommended Installation Refinements
### 1. Robust Installation Script
Create a script that handles common issues:
```bash
#!/bin/bash
# rocky9-install-waldur-agent.sh
set -e
echo "Installing Waldur Site Agent on Rocky Linux 9..."
# Update system
sudo dnf update -y
# Install EPEL
sudo dnf install -y epel-release
# Install development tools (in one command to reduce interruptions)
sudo dnf groupinstall "Development Tools" -y
sudo dnf install -y git curl wget openssl-devel libffi-devel bzip2-devel sqlite-devel python3.11 python3.11-pip python3.11-devel
# Install UV
curl -LsSf https://astral.sh/uv/install.sh | sh
source ~/.bashrc
echo "Base system preparation complete."
```
### 2. Service User Setup
```bash
# Create service user with proper home directory
sudo useradd -r -s /bin/bash -d /opt/waldur-agent -m waldur-agent
# Set up directory structure
sudo mkdir -p /etc/waldur /var/log/waldur-agent
sudo chown waldur-agent:waldur-agent /etc/waldur /var/log/waldur-agent
sudo chmod 750 /etc/waldur /var/log/waldur-agent
```
### 3. SELinux Configuration
```bash
# Set proper contexts
sudo setsebool -P httpd_can_network_connect 1
sudo semanage fcontext -a -t admin_home_t "/opt/waldur-agent(/.*)?"
sudo restorecon -R /opt/waldur-agent/
```
## Next Steps for Complete Validation
1. **Reconnect to System** - When server is available
2. **Complete Installation** - Run through full process
3. **Test All Modes** - Verify each agent mode works
4. **Document Issues** - Any Rocky 9 specific problems
5. **Performance Testing** - Resource usage and stability
## Known Considerations
### Package Management
- DNF is the package manager (not YUM)
- EPEL repository needed for additional packages
- Rocky repositories mirror RHEL structure
### Python Environment
- Default Python 3.9 should work but 3.11 recommended
- UV package manager preferred over pip
- Virtual environments recommended for isolation
### Networking
- Firewalld active by default
- NetworkManager handles network configuration
- IPv6 enabled by default
### Security
- SELinux enforcing by default
- Automatic security updates available via dnf-automatic
- Audit logging enabled
## Lessons Learned
1. **Large Updates** - Rocky 9 systems may require significant updates on fresh install
2. **Reboot Required** - Kernel updates may cause system restart
3. **Connection Stability** - Plan for potential interruptions during system updates
4. **EPEL Dependency** - Many development packages require EPEL repository
## Recommendations for Documentation
1. **Add Reboot Warning** - Inform users about potential system restart during updates
2. **Connection Recovery** - Document how to handle SSH disconnections
3. **Verification Steps** - Add commands to verify installation at each step
4. **Troubleshooting** - Common issues and solutions section

### 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
```

### Design: Optional SLURM REST API (slurmrestd) Execution Mode
# Design: Optional SLURM REST API (slurmrestd) Execution Mode
Status: implemented
Author: Waldur team
This is a design record for the optional `slurmrestd` execution mode, kept
to explain the non-obvious decisions behind it (hand-rolled client, hybrid
REST/CLI split, version mapping, no silent fallback). The feature is built;
the sections below describe what was implemented. User-facing configuration
lives in [the SLURM plugin README](../plugins/slurm/README.md).
## Summary
Add an optional execution mode to the SLURM plugin that talks to
`slurmrestd` over HTTP instead of shelling out to `sacctmgr` /
`scancel`. The mode is selected per offering via `backend_settings`,
defaults to the existing CLI behavior, and requires no changes to the
core agent or to the `SlurmBackend` business logic.
The scope is limited to functionality the REST API provides
**directly**: account, association, user, QOS and limit management,
plus job listing/cancellation and health checks. Usage reporting has no
direct REST equivalent (no `sreport`-style aggregation endpoint) and
therefore **stays on the `sacct` CLI in both modes** — REST mode is a
hybrid: REST for management operations, CLI for accounting reports.
The implementation is a second client class, `SlurmRestClient`, behind a
shared client interface — a **hand-rolled httpx client pinned to a
configurable API version**, not a generated OpenAPI client.
## Motivation
- The agent currently requires SLURM client binaries and a working
munge/SACK auth domain on the host it runs on. A REST mode moves the
management path (accounts, associations, limits, QOS) to HTTP + JWT.
Note: because usage reporting stays on `sacct` for now, REST mode
does not yet remove the need for CLI binaries on hosts that collect
usage — fully remote deployment is future work.
- Structured JSON responses remove a whole class of output-parsing
fragility (`--parsable2` pipe-splitting, locale/format drift between
SLURM releases).
- Several deployments already run `slurmrestd` for other tooling
(Slurm-web, AWS PCS, custom portals); integrating with it is becoming
the standard pattern.
## Background: the CLI architecture
All SLURM interaction funnels through
`plugins/slurm/waldur_site_agent_slurm/client.py`:
- `SlurmClient._execute_command()` builds command lines
(`sacctmgr --parsable2 --noheader --immediate ...`), injects cluster
filtering, and runs them via `BaseClient.execute_command()`
(subprocess).
- Output is parsed into typed structures: `ClientResource`,
`Association`, `SlurmReportLine`.
- `SlurmBackend.__init__` instantiates `SlurmClient` directly; the
backend only calls public client methods and never touches command
syntax itself.
- Non-SLURM operations (homedir creation, project directories, Lustre
quotas, `id -u` checks) live on the **backend**, not the client, and
are out of scope — they behave identically in both modes.
The client's public method surface (~35 methods) is therefore the
natural swap point. Its weakness today: only the 13 `BaseClient`
methods have an interface contract; the ~20 SLURM-specific extension
methods (QOS, fairshare, parents, partitions, job control) do not.
## slurmrestd background
- Two namespaces: `/slurm/vX` (slurmctld: jobs, partitions, ping) and
`/slurmdb/vX` (slurmdbd: accounts, associations, users, QOS, TRES).
- Content schemas come from versioned `data_parser/v0.0.XX` plugins.
Each SLURM major release ships ~4 versions; a version lives ~2 years
(4 major releases), then is removed. As of mid-2026:
- `v0.0.42` — widest deployed common denominator (SLURM 24.11–26.05).
- `v0.0.43` — SLURM 25.05–27.05.
- Authentication: JWT via `X-SLURM-USER-TOKEN` + `X-SLURM-USER-NAME`
headers (or `Authorization: Bearer`). Since SLURM 25.05 running
slurmrestd as root/SlurmUser is unsupported; the production pattern
is slurmrestd on a unix socket or localhost TCP, agent authenticating
as an unprivileged user with `AdminLevel=Administrator` in slurmdbd —
the same privilege model as the `sacctmgr` path today.
- API quirks that the client must handle:
- HTTP 200 with a non-empty `errors[]` array in the body — the body,
not the status code, is authoritative.
- "Maybe-unset" numbers are tri-state structs
`{"set": bool, "infinite": bool, "number": N}`; clearing a limit
means sending `set: false`, not `null`.
- No pagination — job queries must always be bounded with
`start_time` / `end_time` and use `skip_steps=true`.
### Why not a generated OpenAPI client
SchedMD publishes no official Python client and only smoke-tests the
spec against openapi-generator. Community experience with generated
clients is poor: spec validation failures (`--skip-validate-spec`
required), `RecursionError` on package import due to spec size,
generator-version churn, and awkward handling of the tri-state numeric
structs. Production integrators (Slurm-web, AWS PCS consumers)
hand-roll thin clients against the small endpoint set they need. We
need ~15 endpoints; a thin client with a per-version field-mapping
layer is smaller, debuggable, and testable.
## Design
### 1. A shared client interface
`SlurmClientInterface` (ABC, `waldur_site_agent_slurm/interface.py`)
captures the full public surface of `SlurmClient`: the `BaseClient`
methods plus all SLURM-specific extensions (`get/set_account_parent`,
`create_association_with_partition(s)`, QOS management, fairshare,
`cancel_active_user_jobs`, `list_active_user_jobs`,
`get_historical_usage_report`, ...).
Both `SlurmClient` (CLI) and `SlurmRestClient` implement it.
`SlurmBackend` keeps calling `self.client.*` unchanged; its only new
responsibility is choosing the client class from `execution_mode`.
### 2. `SlurmRestClient`
Lives in `waldur_site_agent_slurm/rest_client.py`: a thin transport
layer (`httpx`) with endpoint mappings and payload builders.
- **httpx**, not requests: unix-socket support via
`httpx.HTTPTransport(uds=...)` and a single client type for both UDS
and TCP. Declared as an optional extra
(`waldur-site-agent-slurm[rest]`) so CLI-only deployments gain no
dependency.
- API version is a config string (`api_version`, default `v0.0.43`);
URLs are templated (`/slurmdb/{ver}/associations`). Payload
field-name differences between versions are isolated in a small
mapping layer.
- Every response is checked for body-level `errors[]` / `warnings[]`;
errors map to `BackendError` (same exception contract as CLI).
Warnings are logged. Single-entity existence lookups pass
`allow_errors=True` so a "not found" answer reads as absent rather
than raising.
- Idempotency semantics mirror the CLI client (e.g. the CLI suppresses
"Nothing modified" on `modify`; REST equivalents are similarly
tolerant of no-op updates).
- The `executed_commands` log mirrors the CLI client's for debugging
and tests; in REST mode it also surfaces the commands run by the
delegated CLI client (usage reporting, RawUsage reset).
- Responses are converted into the same typed structures
(`ClientResource`, `Association`, `SlurmReportLine`) so parsers and
backend logic are reused, not duplicated.
### 3. Operation mapping
| CLI today | REST equivalent |
|---|---|
| `sacctmgr add/show/remove account` | `POST/GET/DELETE /slurmdb/vX/accounts`, `/account/{name}` |
| `sacctmgr add user ... account=...` | `POST /slurmdb/vX/users_association` / `/associations` |
| `sacctmgr modify account set GrpTRESMins=...` | `POST /slurmdb/vX/associations` with `max.tres.group.minutes` |
| `sacctmgr modify ... set qos/fairshare/parent` | association payload fields `qos`, `shares_raw`, `parent_account` |
| `sacctmgr show association ...` (limits, users, QOS) | `GET /slurmdb/vX/associations?account=...&cluster=...` |
| QOS create/delete/modify | `GET/POST/DELETE /slurmdb/vX/qos` |
| `scancel -A account [-u user]` | `GET /slurm/vX/jobs` filtered, then `DELETE /slurm/vX/job/{id}` per job |
| `sacctmgr --version` (health check) | `GET /slurm/vX/ping` and `GET /slurmdb/vX/ping` |
| `sacct --starttime --endtime --accounts ...` | **Stays on CLI** — no direct REST equivalent (see Usage reporting) |
| `sacctmgr modify account set RawUsage=0` | **Stays on CLI** — no REST equivalent (see Limitations) |
### 4. Usage reporting — out of scope, stays on CLI
There is no `sreport` equivalent in the REST API: the only path would
be fetching raw `/slurmdb/vX/jobs` records and re-implementing the
aggregation (requested TRES × elapsed minutes per account/user)
client-side. That is **not** functionality the REST API provides
directly, and it feeds billing — re-deriving it from job records would
need a full accounting period of validation against `sacct` before it
could be trusted.
Decision: usage reporting (`get_usage_report`,
`get_historical_usage_report`) is excluded from `SlurmRestClient` and
keeps using `sacct` in both modes. In `execution_mode: rest`, the
backend wires the usage-report methods to the existing CLI client
(composition: `SlurmRestClient` delegates these methods to an internal
`SlurmClient`), so `SlurmBackend` still sees a single client object.
Moving usage reporting to REST (client-side aggregation from
`/slurmdb/jobs`) can be revisited later as a separate proposal.
### 5. Authentication
Config supports, in order of preference:
1. `token_file` — path to a JWT, re-read on HTTP 401, so an external
rotator (e.g. a cron job running `scontrol token`) keeps the agent
working without restarts.
2. `token_env` — environment variable name holding a static token
(consistent with existing secret handling in the agent).
Future (not in initial scope): self-minted HS256 tokens from a shared
`jwt_key`, and JWKS-based RS256 for Keycloak-integrated sites.
The client sends both `X-SLURM-USER-TOKEN` and `X-SLURM-USER-NAME`.
### 6. Configuration
Backward compatible — absence of the new keys means CLI mode:
```yaml
offerings:
- name: "My SLURM Cluster"
backend_type: "slurm"
backend_settings:
# ... all existing settings unchanged ...
execution_mode: "rest" # "cli" (default) | "rest"
rest_api:
url: "unix:///run/slurmrestd/slurmrestd.sock" # or http://localhost:6820
api_version: "v0.0.43" # default; pin to what your SLURM ships
username: "waldur-agent"
token_file: "/etc/waldur/slurmrestd.token"
# token_env: SLURM_JWT # alternative to token_file
verify_ssl: true # for TLS-terminating reverse proxies
```
`SlurmBackendSettingsSchema` has an `execution_mode` literal and a
nested `rest_api` model (required iff `execution_mode: rest`).
`diagnostics()` reports the mode, endpoint, API version, and ping
results for both namespaces.
### 7. Limitations (documented, not worked around silently)
- Usage reporting stays on the `sacct` CLI (see section 4), so REST
mode still requires SLURM client binaries and cluster auth on hosts
that run usage collection.
- `reset_raw_usage` (`sacctmgr modify account set RawUsage=0`) has no
REST endpoint and likewise stays on the CLI client.
- Beyond these two explicitly delegated operations, there is no
automatic REST→CLI fallback on errors: silent divergence between
modes is worse than a loud failure. The mode is an explicit
per-offering choice.
- The slurmdb write path is younger than the CLI (crash in
`accounts_association` and a QOS POST memory leak were fixed only in
SLURM 25.11). REST mode therefore stays **opt-in** with CLI as the
default for the foreseeable future, and the docs state the minimum
recommended SLURM version (25.11) for REST mode even where older
API versions would technically work.
## Testing
- **Unit tests** (`tests/test_rest_client.py`) with `httpx.MockTransport`,
asserting request paths, query params, and payloads — the REST analogue
of `tests/test_command_construction.py`.
- **Config tests** (`tests/test_rest_mode_config.py`) cover schema
validation and client selection.
- **E2E against slurm-emulator** (`tests/e2e/test_e2e_rest_api.py`):
the emulator ships a slurmrestd-compatible API (v0.0.46); the suite
starts it as a subprocess and drives the real `SlurmRestClient` over
HTTP. Gated by `WALDUR_E2E_TESTS` and skipped unless the emulator's
slurmrestd app is importable.
- **E2E against real slurmrestd**: still future work — a containerized
slurmrestd + slurmdbd, gated like the existing e2e suites.
## Future work
Tracked separately, not part of this design:
- Usage reporting via REST (client-side aggregation from
`/slurmdb/jobs`), enabling fully CLI-free deployments.
- Self-minted HS256 / JWKS-based authentication.

### SLURM Storage Quotas
# SLURM Storage Quotas
The SLURM plugin can apply two independent kinds of filesystem quotas during
normal agent operation:
- **Per-user home directory quota** (`homedir_quota`) — runs in
`membership_sync` mode when a new user is added to a SLURM account and a
homedir is created. Sets a *user* quota on the user's home directory via
CephFS xattrs, XFS user quotas, or Lustre user quotas.
- **Per-project directory + Lustre group/project quota**
(`project_directory`) — runs in `order_process` mode during resource
creation (`_pre_create_resource`). Creates a shared project directory,
applies ownership / permissions / ACLs, and optionally sets a Lustre
*project* quota keyed on the LDAP group GID.
The two are independent — you can enable either, both, or neither. Failures
in either are logged but do not abort agent operation.
## Subsystem A — Per-user home directory quota
This lives in the **core** module
`waldur_site_agent/backend/quota.py`
and is invoked from `BaseBackend.create_user_homedirs`
(`waldur_site_agent/backend/backends.py`)
whenever the agent creates a new user homedir. It is wired into the SLURM
backend through the standard
`enable_user_homedir_account_creation` /
`default_homedir_umask` settings.
The SLURM backend triggers `create_user_homedirs` from three call sites:
- `post_create_resource` — during `order_process`, after a resource is
created, for the offering users in the user context.
- `add_users_to_resource` — during `membership_sync`, for users newly added
to a resource.
- `process_existing_users` — during `membership_sync`, to ensure homedirs
exist for already-known users.
It is also called by the standalone `create_homedirs_for_offering_users`
utility (`waldur_site_agent/common/utils.py`).
### Homedir quota configuration
```yaml
backend_settings:
enable_user_homedir_account_creation: true
default_homedir_umask: "0077"
# Optional override. When set, the agent applies the quota to
# {homedir_base_path}/{username}. When unset, the path is taken from
# the system passwd database (pwd.getpwnam(username).pw_dir).
homedir_base_path: "/cephfs/home"
homedir_quota:
provider: "ceph_xattr" # one of: ceph_xattr | xfs | lustre
# ...provider-specific fields below
```
The schema is `HomedirQuotaConfig` in `backend/quota.py`. It uses
`extra="forbid"`, so unknown keys are rejected. An invalid configuration is
logged and treated as "no quota" — homedir creation still proceeds.
### Provider: `ceph_xattr`
Sets quotas via extended attributes on the homedir.
```yaml
homedir_quota:
provider: "ceph_xattr"
max_bytes: "1099511627776" # 1 TiB in bytes; string. Optional.
max_files: 100000 # integer. Optional.
```
Commands executed (per attribute):
```bash
setfattr -n ceph.quota.max_bytes -v 1099511627776
getfattr --only-values -n ceph.quota.max_bytes # verification
```
The verify step compares the read-back value against the configured one and
logs a warning on mismatch.
### Provider: `xfs`
Sets XFS user quotas via `xfs_quota`. Block limits accept human-readable
suffixes (`g`, `t`, …).
```yaml
homedir_quota:
provider: "xfs"
mount_point: "/home" # required
block_softlimit: "900g"
block_hardlimit: "1t"
inode_softlimit: 90000
inode_hardlimit: 100000
```
Command executed:
```bash
xfs_quota -x -c "limit -u bsoft=900g bhard=1t isoft=90000 ihard=100000 alice" /home
xfs_quota -x -c "quota -u -N -b -h alice" /home # verification (logged)
```
If `mount_point` is missing or no limits are set, the quota step is
skipped with a log message. The homedir itself is still created.
### Provider: `lustre`
Sets Lustre user quotas via `lfs setquota`. Block limits are expressed in
**kilobytes**.
```yaml
homedir_quota:
provider: "lustre"
mount_point: "/home"
block_softlimit: "943718400" # ~900 GiB in KiB
block_hardlimit: "1048576000" # ~1 TiB in KiB
inode_softlimit: 90000
inode_hardlimit: 100000
```
Command executed:
```bash
lfs setquota -u alice -b 943718400 -B 1048576000 -i 90000 -I 100000 /home
lfs quota -u alice /home # verification (logged)
```
### When the quota is applied
`BaseBackend.create_user_homedirs` iterates over the set of usernames it is
given. For each one:
1. `client.create_linux_user_homedir(username, umask)` is called.
2. If `homedir_quota` is configured, the quota is then applied on the resolved
homedir path.
3. A failure for one user is logged but does not stop processing of the
remaining users.
4. If homedir creation itself fails for a user, the quota step is skipped for
that user.
## Subsystem B — Project directory + Lustre group/project quota
SLURM-plugin specific. Schemas: `ProjectDirectoryConfig` and
`LustreQuotaConfig` in
`plugins/slurm/waldur_site_agent_slurm/schemas.py`.
Implementation: `_setup_project_directory` /
`_set_lustre_quota` in
`plugins/slurm/waldur_site_agent_slurm/backend.py`.
### Project directory configuration
```yaml
backend_settings:
project_directory:
enabled: true
base_path: "/valhalla/projects" # default
owner: "nobody" # uid/owner for chown
permissions: "770" # octal, applied via chmod
set_gid: true # chmod g+s
set_acl: true # setfacl -R -m group::rwx,d:group::rwx
# Optional Lustre group/project quota (see below for prerequisites)
lustre_quota:
mount_point: "/valhalla"
block_softlimit: 5368709120 # kilobytes
block_hardlimit: 6442450944
inode_softlimit: 5000000
inode_hardlimit: 7000000
```
### What the agent does on resource creation
When `project_directory.enabled: true`, `_pre_create_resource` calls
`_setup_project_directory(resource_backend_id)` after the SLURM account
hierarchy is created. It executes (in order):
```bash
mkdir -p /
chmod 770 /
chmod g+s / # if set_gid
chown : /
setfacl -R -m group::rwx,d:group::rwx # if set_acl
```
`` defaults to the resource backend ID. It can be overridden
through two extra keys that are read by the backend but not (yet) part of
the schema fields — they pass through because the schema has
`extra="allow"`:
- `group_owner_source`: when set to `"project_id"` (the default), the group
name is the SLURM account name. Any other value falls back to:
- `group_name`: explicit override of the group used in `chown` / `setfacl`.
### Lustre group/project quota: prerequisites
The Lustre quota step inside `_setup_project_directory` runs **only if all
three** of the following are true:
1. `lustre_quota` is configured.
2. The SLURM backend has an LDAP client configured (`backend_settings.ldap`).
3. `LdapClient.get_group_gid(group_name)` returns a non-`None` GID.
If any of these is missing the directory is still created but the Lustre
quota is silently skipped. No warning is emitted today — if you intend to
use Lustre project quotas, make sure the offering has `ldap:` configured
and that the project group exists in LDAP before the resource is created.
If the prerequisites are met, the agent runs:
```bash
lfs setquota -p [-b ] [-B ] \
[-i ] [-I ]
lfs project -p -r -s
```
Each `-b/-B/-i/-I` flag is included only if the corresponding limit is set
in the configuration. `mount_point` defaults to `/valhalla`.
Note that this is a **project quota** (`-p`), not a group or user quota. The
GID coming from LDAP is reused as the Lustre project ID, and the directory
tree is tagged with that project ID via `lfs project -r -s`.
Unlike subsystem A, no verification step is run. Failures from
`lfs setquota` are logged but do not abort resource creation.
## Examples
A complete reference example showing both subsystems is in
[`examples/waldur-site-agent-config.yaml.example`](../examples/waldur-site-agent-config.yaml.example):
- The `Example SLURM Offering` shows `homedir_quota` placement with the
`ceph_xattr` provider (commented out).
- The `Discoverer CPU` offering shows `homedir_base_path`, the `lustre` and
`xfs` `homedir_quota` provider examples (commented out), and a full
uncommented `project_directory` block with `lustre_quota`.
## Caveats and known inconsistencies
- **`HomedirQuotaConfig.block_softlimit` / `block_hardlimit` are typed as
`Optional[str]`** (to allow XFS suffixes like `"900g"`), while
`LustreQuotaConfig.block_softlimit` / `block_hardlimit` are typed as
`Optional[int]`. Use integers (kilobytes) for `project_directory.lustre_quota`
even if you use string-with-suffix for `homedir_quota` on Lustre.
- **`group_owner_source` and `group_name`** are accepted by the runtime but
are not declared fields of `ProjectDirectoryConfig` (they pass through via
`extra="allow"`). They are documented here for completeness.
- **Lustre project quota silently no-ops without LDAP.** This is a current
implementation choice — the quota requires the GID and the GID lookup goes
through the LDAP client.
- **No verification** is run after `lfs setquota -p` (the homedir-quota path
*does* verify). Operators should spot-check with `lfs quota -p
` after onboarding the first project.
## Operator troubleshooting
Verify a user's home quota:
```bash
# Ceph
getfattr --only-values -n ceph.quota.max_bytes /cephfs/home/alice
# XFS
xfs_quota -x -c 'quota -u -N -b -h alice' /home
# Lustre
lfs quota -u alice /home
```
Verify a project directory's Lustre quota / project ID:
```bash
lfs quota -p /valhalla
lfs project -d /valhalla/projects/
```
The agent logs each command it issues and each verification result. Search
the structured logs for `homedir`, `Lustre quota`, or
`Created project directory` to trace activity.

### 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" # DefaultAccount= on user associations
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
default_homedir_umask: "0077"
# 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`: `DefaultAccount=` set on user associations in the 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 `log_level` in the agent configuration file:
```yaml
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

### Upgrading Waldur Site Agent
# Upgrading Waldur Site Agent
This guide covers what to consider before upgrading, the recommended upgrade sequence,
and how to validate that the new agent version works correctly with your Waldur Mastermind instance.
## What to Consider Before Upgrading
### The `waldur-api-client` pin is the compatibility contract
The agent talks to Waldur Mastermind through the `waldur-api-client` Python package,
which is a generated SDK pinned to an **exact version** in the agent's `pyproject.toml`.
A compatible pair means:
- No API endpoints used by the agent have been removed or had incompatible schema changes
in Mastermind since that SDK version was generated.
When you upgrade the agent to a new release, its `waldur-api-client` pin almost always
bumps too. Check the [CHANGELOG](../CHANGELOG.md) for entries about `waldur-api-client`
upgrades — these indicate a new API surface is required and you must ensure Mastermind
is recent enough to support it.
### Review the CHANGELOG for breaking changes
Before upgrading, read the CHANGELOG entries between your current version and the target
version and look for:
| Signal | What it means |
|---|---|
| New required configuration keys | Add them to the config file before starting the agent, or it will fail to start. |
| Removed configuration keys | Remove them — the agent may reject an unrecognised key. |
| Backend behaviour changes | Check the CHANGELOG description; verify flags and settings match the new expectations. |
| New plugin packages | Install the relevant `waldur-site-agent-` package if you use that backend. |
### Verify Mastermind is compatible first
The agent requires Mastermind to expose API endpoints that match its `waldur-api-client` pin.
**Upgrade Mastermind before the agent** — a newer agent talking to an older Mastermind can
fail with `404 Not Found` or schema validation errors on endpoints the old Mastermind
does not yet expose.
### STOMP / event-process mode
If you run `agent-event-process`, also check whether any new event types were added.
The agent subscribes to topics at startup; a configuration mismatch between agent and
the RabbitMQ/STOMP broker does not prevent startup but can cause silent gaps in processing.
---
## Upgrade Order
**Always upgrade Waldur Mastermind first, then the site agent.**
```text
1. Upgrade Waldur Mastermind
2. Verify Mastermind is healthy (API responds, worker processes running)
3. Stop site agent services
4. Upgrade waldur-site-agent (and plugins)
5. Update configuration if the release requires new keys
6. Start site agent services
7. Validate (see below)
```
### Why Mastermind first?
The agent reads from and writes to Mastermind. During a Mastermind upgrade the agent
can safely continue running against the old version — it will use existing endpoints.
The reverse is not safe: a new agent may call endpoints that do not yet exist in an
older Mastermind, causing immediate errors.
### Stopping services
```bash
# Polling mode
systemctl stop waldur-agent-order-process waldur-agent-membership-sync waldur-agent-report
# Event-process (STOMP) mode
systemctl stop waldur-agent-event-process waldur-agent-report
```
### Upgrading the package
```bash
# PyPI install
pip install --upgrade waldur-site-agent
# With specific plugins (upgrade all at once to keep versions in sync)
pip install --upgrade \
waldur-site-agent \
waldur-site-agent-slurm \
waldur-site-agent-keycloak-client
```
All plugin packages share the same version number as the core package.
**Always upgrade all installed plugins together with the core.**
### Helm chart
If you deploy via Helm, the chart version mirrors the agent release version.
Update `image.tag` (or use the chart's default) and run:
```bash
helm upgrade waldur-site-agent waldur/waldur-site-agent --version
```
---
## Validating the Upgrade
### 1. Run diagnostics
`waldur_site_diagnostics` checks connectivity, token permissions, offering availability,
and backend health for every offering in the configuration:
```bash
waldur_site_diagnostics -c /etc/waldur/waldur-site-agent-config.yaml
```
A successful run prints `DIAGNOSTICS START … DIAGNOSTICS END` with no errors and exits 0.
Any `ERROR` line indicates a problem to fix before starting production services.
### 2. Smoke-test order processing
After starting services, verify the agent is processing work by checking logs for
normal activity within one reconciliation interval:
```bash
# Polling mode — look for successful order/membership cycles
journalctl -u waldur-agent-order-process.service -f
# Event-process mode — look for STOMP connection confirmation and heartbeats
journalctl -u waldur-agent-event-process.service -f
```
Signs of a healthy agent:
- `Connected to STOMP broker` (event-process mode)
- `Processing orders…` / `Membership sync complete` (polling mode)
- No repeated `ERROR` lines within the first few minutes
- Heartbeat updates visible in Waldur UI under the offering's agent status
### 3. Check the Waldur UI
In the Waldur service provider interface, open the offering and verify:
- Agent heartbeat timestamp is recent (updated within the last reconciliation interval)
- No offering-level error banners
### 4. Run a test order (optional but recommended for major upgrades)
Place a small test order through Waldur and confirm the agent picks it up, provisions
the backend resource, and transitions the order to `Done` within a reasonable time.
---
## SLURM Plugin
See [SLURM Plugin Upgrade Notes](../plugins/slurm/docs/upgrading.md) for SLURM-specific
`backend_settings` reference, QoS configuration, account hierarchy behaviour,
and post-upgrade validation steps.
---
## Rollback
The agent is stateless — its only persistent state is in Waldur Mastermind and the
backend (e.g. SLURM accounts). Rolling back is safe as long as the older agent version
is compatible with the current Mastermind version.
```bash
pip install waldur-site-agent==
systemctl restart waldur-agent-*
```
If you also rolled back Mastermind, roll it back before rolling back the agent,
following the same Mastermind-first order.

### Waldur Plugin: Offering User Sync
# Waldur Plugin: Offering User Sync
This document covers offering user synchronization in the **Waldur federation plugin**
(`plugins/waldur/`), where the site agent bridges two Waldur instances (A and B).
For the generic offering user state machine and username management backend system,
see [offering-users.md](offering-users.md).
## Architecture
In a Waldur federation, Waldur A is the consumer-facing marketplace and Waldur B
hosts the actual resources. The site agent runs between them:
```text
┌──────────────┐ ┌──────────────┐ ┌──────────────┐
│ Waldur A │◄───────►│ Site Agent │◄───────►│ Waldur B │
│ (source) │ REST │ (waldur │ REST │ (target) │
│ │ STOMP │ plugin) │ STOMP │ │
└──────────────┘ └──────────────┘ └──────────────┘
```
The agent manages three concerns for offering users:
1. **Username generation** — create an account username on the service provider side
2. **User resolution** — map a Waldur A user identity to a Waldur B user UUID
3. **Project membership** — add/remove resolved users to Waldur B projects
## Sync Flows Overview

```
## Case 1: Happy Path — Username Generation Succeeds
The most common case. A user joins a project, gets an OfferingUser, and the agent
generates a username on the first sync cycle.
```mermaid
sequenceDiagram
participant MA as Waldur A
participant SA as Site Agent
participant MB as Waldur B
MA->>MA: User gets project role
MA->>MA: Create OfferingUser (CREATION_REQUESTED)
SA->>MA: List offering users (poll)
MA-->>SA: OfferingUser (state=REQUESTED)
SA->>MA: POST begin_creating
Note over MA: state → CREATING
SA->>SA: Backend generates username
SA->>MA: PATCH username="jsmith"
Note over MA: state → OK (auto-transition)
SA->>MB: Resolve user (CUID/email/identity bridge)
MB-->>SA: user_uuid on B
SA->>MB: Add user to project (role mapped)
```
## Case 2: Username Generation Fails — Network Error
The backend is unreachable (e.g., identity provider down). The user stays in CREATING
and is retried on every subsequent sync cycle until the backend recovers.
```mermaid
sequenceDiagram
participant MA as Waldur A
participant SA as Site Agent
participant IDP as Identity Provider
SA->>MA: List offering users
MA-->>SA: OfferingUser (state=REQUESTED)
SA->>MA: POST begin_creating
Note over MA: state → CREATING
SA->>IDP: get_or_create_username()
IDP-->>SA: ConnectionError
Note over SA: Non-BackendError → state stays CREATING
Note over SA,IDP: --- Next sync cycle ---
SA->>MA: List offering users
MA-->>SA: OfferingUser (state=CREATING)
SA->>IDP: get_or_create_username()
IDP-->>SA: "jsmith"
SA->>MA: PATCH username="jsmith"
Note over MA: state → OK
```
## Case 3: Username Generation Fails — Backend Error
The backend returns a structured error (e.g., SLURM account limit reached).
The user transitions to ERROR_CREATING so admins can see the failure. On the
next cycle, the agent retries via `begin_creating`.
```mermaid
sequenceDiagram
participant MA as Waldur A
participant SA as Site Agent
SA->>MA: List offering users
MA-->>SA: OfferingUser (state=REQUESTED)
SA->>MA: POST begin_creating
Note over MA: state → CREATING
SA->>SA: get_or_create_username() → BackendError
SA->>MA: POST set_error_creating
Note over MA: state → ERROR_CREATING
Note over SA: --- Next sync cycle ---
SA->>MA: List offering users
MA-->>SA: OfferingUser (state=ERROR_CREATING)
SA->>MA: POST begin_creating (retry)
Note over MA: state → CREATING
SA->>SA: get_or_create_username() → "jsmith"
SA->>MA: PATCH username="jsmith"
Note over MA: state → OK
```
## Case 4: Account Linking Required
The identity provider requires the user to manually link their account
(e.g., accept terms, verify institutional affiliation). The OfferingUser moves
to PENDING_ACCOUNT_LINKING with a service provider comment and URL pointing
to the linking form.
```mermaid
sequenceDiagram
participant MA as Waldur A
participant SA as Site Agent
participant IDP as Identity Provider
SA->>MA: POST begin_creating
Note over MA: state → CREATING
SA->>IDP: get_or_create_username()
IDP-->>SA: OfferingUserAccountLinkingRequiredError
(comment_url="https://idp.example.com/link")
SA->>MA: POST set_pending_account_linking
(comment, comment_url)
Note over MA: state → PENDING_ACCOUNT_LINKING
Note over IDP: User clicks link, completes linking
Note over SA: --- Next sync cycle ---
SA->>MA: List offering users
MA-->>SA: OfferingUser (state=PENDING_ACCOUNT_LINKING)
SA->>IDP: get_or_create_username()
IDP-->>SA: "jsmith"
SA->>MA: POST set_validation_complete
SA->>MA: PATCH username="jsmith"
Note over MA: state → OK
```
If the user has not completed linking yet, the backend raises
`OfferingUserAccountLinkingRequiredError` again. The agent detects the user
is already in PENDING_ACCOUNT_LINKING and skips the redundant API call (idempotent).
## Case 5: Additional Validation Required
Similar to account linking, but for a different kind of manual verification
(e.g., admin approval of institutional affiliation, compliance check).
Uses `OfferingUserAdditionalValidationRequiredError`.
The flow is identical to Case 4, with `PENDING_ADDITIONAL_VALIDATION` instead of
`PENDING_ACCOUNT_LINKING`.
Cross-transitions are also possible: a user in PENDING_ACCOUNT_LINKING may transition
to PENDING_ADDITIONAL_VALIDATION (or vice versa) if the backend reports a different
requirement on retry.
## Case 6: Waldur B Username Sync (Federation)
In the Waldur federation plugin, usernames may come from Waldur B rather than being
generated locally. The flow uses `sync_offering_user_usernames()` to pull usernames
from Waldur B's offering users and write them to Waldur A's offering users.
```mermaid
sequenceDiagram
participant MA as Waldur A
participant SA as Site Agent
participant MB as Waldur B
Note over MB: OfferingUser on B gets username
(via B's own site agent)
SA->>MB: List offering users (state=OK)
MB-->>SA: user_username="alice@edu", username="alice01"
SA->>MA: List offering users (state=OK,CREATING,REQUESTED)
MA-->>SA: user_username="alice@edu", username="" (state=CREATING)
Note over SA: Match by user_username (common identity)
SA->>MA: PATCH username="alice01"
Note over MA: state → OK (auto-transition)
```
This sync runs in two modes:
- **STOMP-driven**: When a Waldur B offering user is created/updated with a username,
the `make_target_offering_user_handler` triggers an immediate sync.
- **Periodic reconciliation**: Every 60 minutes (configurable), catches any updates
missed due to STOMP disconnections.
## Case 7: Event-Driven User Addition (STOMP)
When a user role change event arrives via STOMP, the agent processes it in real time
without waiting for the next polling cycle.
```mermaid
sequenceDiagram
participant MA as Waldur A (STOMP)
participant SA as Site Agent
participant MB as Waldur B
MA->>SA: USER_ROLE event
(user_uuid, project_uuid, granted=true)
SA->>MA: List offering users for user
MA-->>SA: OfferingUser (state=OK, username="jsmith")
SA->>SA: _update_offering_users (generate username if blank)
SA->>MB: Resolve user by CUID/email
MB-->>SA: user_uuid on B
SA->>MB: Add user to project (with role mapping)
```
If the offering user has **no username** (e.g., still in CREATING state),
the event handler returns early without adding the user to Waldur B. The user
will be added on a subsequent polling cycle after username generation completes.
## Case 8: Offering User Attribute Forwarding
When a new offering user is created or attributes change, the STOMP event handler
forwards user attributes to the membership sync backend (e.g., the identity bridge).
This ensures user profiles are pushed to Waldur B even before username generation.
```text
STOMP OFFERING_USER "create" event (username="", attributes={...})
→ _forward_user_attributes_to_backend()
→ backend.update_user_attributes(username="", attributes)
```
This path does **not** trigger username generation — that only happens via the
polling-based membership sync.
## Recovery in `event_process` Mode
In `event_process` mode, the full membership sync (`process_offering()`) only
runs **once at startup**. After that, user changes are handled by STOMP events.
Two periodic reconciliation functions cover gaps:
| Function | Condition | What it does |
|----------|-----------|-------------|
| `run_periodic_offering_user_reconciliation()` | `membership_sync_backend` set | Retries stuck users |
| `run_periodic_username_reconciliation()` | `username_reconciliation_enabled` | Syncs usernames B→A |
Both run on the reconciliation timer (default: every 60 minutes).
### Waldur federation: `username_reconciliation_enabled` is required
In the waldur federation plugin, the identity bridge username backend
**does not generate usernames** — it pushes user profiles to Waldur B and
returns an empty string. The actual username is assigned by Waldur B's
service provider and must be **pulled back** via `sync_offering_user_usernames()`.
This means:
- `run_periodic_offering_user_reconciliation()` alone is **insufficient** for
the waldur plugin — it pushes profiles to identity bridge (useful) but
cannot assign usernames.
- `run_periodic_username_reconciliation()` is the function that actually
pulls usernames from Waldur B and writes them to Waldur A, triggering
the auto-transition to OK.
- **Without `username_reconciliation_enabled: true`**, users that get stuck
after startup will not self-heal until the agent is restarted.
```yaml
# Required for waldur federation deployments
offerings:
- name: "Federated HPC"
username_reconciliation_enabled: true # <-- enables periodic B→A sync
membership_sync_backend: "waldur"
# ...
```
### Non-federation plugins (SLURM, MOAB, etc.)
For plugins where the username backend generates usernames locally (e.g.,
the `base` backend or FreeIPA), `run_periodic_offering_user_reconciliation()`
is sufficient. It retries `update_offering_users()` which calls
`get_or_create_username()` on the local backend. No
`username_reconciliation_enabled` setting is needed.
### Thread safety
STOMP callbacks run in **receiver threads** (separate from the main loop).
Both the periodic reconciliation and STOMP handlers can call
`_update_offering_users()` on the same user concurrently. This is safe
because:
- **No double creation**: OfferingUsers are created by Mastermind, not the
agent. The `(offering, user)` unique constraint prevents duplicates.
- **`begin_creating()` on wrong state**: Returns HTTP 400 (FSM validation).
Caught by the exception handler, logged, processing continues.
- **Double PATCH with same username**: Idempotent (last-write-wins, same value).
- **PATCH with empty username**: `_update_user_username()` returns `False` when
the backend returns `""` — no API call is made.
## Processing Entry Points
| Entry Point | Trigger | What It Does | Username Generation? |
|-------------|---------|--------------|---------------------|
| `process_offering()` | Polling (cron / main loop) | Full sync of all resources and users | Yes |
| `process_project_user_sync()` | STOMP USER_ROLE event (no user_uuid) | Full user sync for one project | Yes |
| `process_user_role_changed()` | STOMP USER_ROLE event (with user_uuid) | Add/remove one user | Yes |
| `on_offering_user_message_stomp()` | STOMP OFFERING_USER from A | Forward attributes | No |
| `make_target_offering_user_handler()` | STOMP OFFERING_USER from B | Sync usernames B→A | No |
| `run_periodic_username_reconciliation()` | Timer (every 60 min) | Sync usernames B→A | No |
| `run_periodic_offering_user_reconciliation()` | Timer (every 60 min) | Retry stuck users | Yes |

```
## Troubleshooting
### User stuck in CREATING
**Cause**: Username generation failed with a non-`BackendError` exception (e.g.,
`ConnectionError`, `TimeoutError`). The state stays CREATING so it will be retried
on the next sync cycle.
**Check**: Agent logs for the offering user UUID — look for `get_or_create_username` errors.
**Resolution**: Fix the underlying connectivity issue. The agent will auto-recover on the
next cycle.
### User stuck in ERROR_CREATING
**Cause**: Username generation failed with a `BackendError`. The state is set to
ERROR_CREATING so admins can see the failure.
**Check**: The error details in the agent log and the service provider comment on
the offering user in Waldur.
**Resolution**: Fix the backend issue. The agent will retry via `begin_creating` →
`get_or_create_username` on the next cycle.
### User stuck in PENDING_ACCOUNT_LINKING / PENDING_ADDITIONAL_VALIDATION
**Cause**: The identity provider requires manual user action (linking, verification).
**Check**: The `service_provider_comment` and `service_provider_comment_url` fields on
the offering user in Waldur. These contain instructions and a link for the user.
**Resolution**: The user must complete the required action. The agent will detect
completion on the next sync cycle and transition to OK.
### Username not synced from Waldur B
**Cause**: The offering user on Waldur B doesn't have a username yet, user identity
matching failed, or `username_reconciliation_enabled` is not set.
**Check**:
1. Is `username_reconciliation_enabled: true` in the offering config?
Without it, periodic B→A username sync does not run.
2. Does the offering user exist on Waldur B? Check with the target API.
3. Is the Waldur B offering user in OK state with a username?
4. Do the `user_username` fields match between A and B?
**Resolution**: Ensure `username_reconciliation_enabled: true` is set for
waldur federation offerings. Ensure consistent identity (CUID/email) across
instances. If using identity bridge, verify `identity_bridge_source` is
configured correctly.

### 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)
- `WALDUR_SITE_AGENT_REPORT_PERIOD_MINUTES`: Reporting period (default: 30)
- `WALDUR_SITE_AGENT_MEMBERSHIP_SYNC_PERIOD_MINUTES`: Membership sync period (default: 5)
- `SENTRY_ENVIRONMENT`: Sentry environment name

### Basic Username Management plugin for Waldur Site Agent
# Basic Username Management plugin for Waldur Site Agent
This plugin provides basic username generation and management capabilities for Waldur Site Agent.
## Installation
See the main [Installation Guide](../../docs/installation.md) for platform-specific installation instructions.

### Ceph S3 Storage Plugin for Waldur Site Agent
# Ceph S3 Storage Plugin for Waldur Site Agent
Integrates Waldur Mastermind with Ceph object storage. Each marketplace resource
creates one RGW user, with its access keys managed as Waldur resource API keys
and its ordered ceiling applied as an RGW quota.
Two **flavours** reach the same RGW concepts by different routes:
| | `croit` (default) | `radosgw` |
|---|---|---|
| Talks to | croit's management API | RadosGW Admin Ops on the gateway |
| Authenticates with | bearer token or basic auth | SigV4, as an RGW user with caps |
| Users, keys, quotas | yes | yes |
| GB-day metering | yes | **no** — see [Usage Reporting](#usage-reporting) |
The flavours differ only inside the client. Everything above it — key lifecycle,
quota mapping, metadata, Waldur plumbing — is shared.
## Features
- **Automatic S3 User Creation**: One S3 user per marketplace resource with slug-based naming
- **Usage-Based Billing**: storage billed in GB-days, integrated from croit's
metrics over the billing period. Object counts are not billed
- **Safety Quota Enforcement**: an ordered ceiling is applied as both a RadosGW
user quota (the tenant total) and a bucket quota (per bucket)
- **Credential Management**: two S3 access keys per resource, encrypted in Waldur and
managed from the portal (reveal / rotate). The count is fixed at provisioning —
rotation replaces a key's value in place, so there is no add or revoke
- **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/ceph-s3

Talks Admin Ops directly to the gateway, for a Ceph cluster croit does not manage.
```yaml
backend_type: "ceph_s3"
order_processing_backend: "ceph_s3"
membership_sync_backend: "ceph_s3"
# No reporting_backend: this flavour cannot meter. See Usage Reporting.
backend_settings:
flavour: "radosgw"
s3_endpoint: "https://s3.example.com" # Admin Ops hangs off this host
admin_access_key: "ADMINACCESSKEY000000"
admin_secret_key: "..."
s3_region: "us-east-1" # must match what clients sign with
admin_path: "admin" # only if rgw_admin_entry was renamed
verify_ssl: true
```
`api_url`, `token`, `username` and `password` belong to the croit flavour and are
**rejected** here rather than ignored — an offering carrying both sets is a
half-finished migration, and silently picking one would authenticate somewhere the
operator did not intend.
#### Two behaviours that differ from croit
- **No GB-day metering.** Admin Ops exposes no per-user stored-bytes series:
`/admin/usage` is bandwidth and operation counts, and bucket stats are a
point-in-time size. There is nothing to integrate, so leave `reporting_backend`
unset and bill this offering on a fixed component.
- **Quota enforcement overshoots.** RGW syncs bucket statistics into the
user-quota check periodically rather than on every write. Measured on squid: a
6 MiB ceiling against 5 MiB already stored accepted a further 7 MiB before
answering `QuotaExceeded`. The ceiling bounds the invoice approximately, not
exactly.
### Configuration Options
#### Backend Settings
- **`flavour`** (optional, default: `"croit"`): `croit` or `radosgw`
- **`api_url`** (croit only, required): croit **management** API base URL (/api is appended)
- **`s3_endpoint`** (required): the S3 data endpoint tenants connect to. This is a
*different host* from `api_url` — RadosGW runs on the storage nodes while the
management API runs on the croit VM, and croit exposes no VIP or DNS name to derive
it from. Point it at a load balancer or DNS name in front of the RGW nodes
- **`s3_region`** (optional, default: `"default"`): the region S3 clients sign with.
Maps to the RadosGW zonegroup's `api_name`; croit exposes no endpoint to read it back,
and `"default"` is Ceph's out-of-the-box zonegroup name. Set it if yours was named
- **`token`** (croit only): bearer token for API authentication
- **`username`** (croit only): API username (alternative to token)
- **`password`** (croit only): API password (alternative to token)
- **`admin_access_key`** (radosgw only, required): access key of the RGW user
holding `users=*;buckets=read`
- **`admin_secret_key`** (radosgw only, required): its secret
- **`admin_path`** (radosgw only, default: `"admin"`): the value of
`rgw_admin_entry`, if the operator renamed it
- **`verify_ssl`** (optional, default: `true`): Enable/disable SSL certificate verification
- **`timeout`** (optional, default: `30`): Request timeout in seconds
- **`allocation_prefix`** (optional, default: `"waldur-"`): namespace every uid this
agent creates is built under — the only setting that changes a provisioned uid. A
core setting, but the core defaults it to `""`, which this plugin overrides: an
empty namespace puts a consumer-chosen resource name straight into the cluster's
global one. See Username Generation
- **`default_tenant`** (croit only, optional): Default RadosGW tenant. Rejected on
the radosgw flavour: a tenanted uid is `tenant$uid`, and the client's path
validator refuses `$`
- **`default_placement`** (optional): Default placement rule. Honoured by both
flavours
- **`default_storage_class`** (croit only, optional): Default storage class.
Rejected on the radosgw flavour: Admin Ops user-create takes a placement but no
storage class
The billing period boundary for GB-day reporting follows the **agent's global**
`timezone`, which the reporting processor injects into the backend — the same value
it uses to file the usage, so the two cannot drift. The configuration validator
rejects a timezone that does not parse: the backend used to fall back to UTC while
the processor fell back to naive system local time, so near a month boundary a typo
filed a whole period's usage against the wrong month.
**Set it to whatever Mastermind computes billing periods in.** The agent derives both
the integration bounds and the `billing_period` it files against from its own clock,
so an agent on `Europe/Tallinn` reporting to a UTC Mastermind integrates the first
hours of each month into the period Mastermind has already closed. A fixed component
would not notice; GB-days move storage-hours onto the wrong invoice.
#### Component Types
##### Usage-Based Storage (`s3_storage`)
The only billed component. Reports GB-days — storage integrated over the billing
period — with optional safety quota enforcement:
```yaml
s3_storage:
accounting_type: "usage"
backend_name: "storage"
label: "Storage"
measured_unit: "GB-day" # GB x days; see Usage Reporting
unit_factor: 1000000000 # decimal GB (1000 GB = 1 TB), not GiB
```
**`unit_factor` is mandatory here and must be above 1.** The core config model
defaults it to `1.0` and normalises every component through that default, so an
omitted value arrives at the plugin as a real one — nothing downstream can tell
"not configured" from "configured as 1". At 1 both directions break silently: the
quota path sends an ordered 5 GB ceiling as **5 bytes**, capping the tenant at
nothing, and the metering path divides by 1, reporting byte-days against a GB-day
price. The backend therefore refuses to construct rather than start and misbill,
so a missing `unit_factor` fails at agent startup with the component named.
Setting `limit_amount`/`limit_period` on this component is harmless but noisy.
`validate_amount()` only *raises* for non-usage components; for a usage component
it logs a warning and the report lands anyway. Two things make that warning fire
early: a GB-denominated threshold is compared against a GB-day amount, and the
running total includes the row about to be overwritten, so cumulative reporting
roughly double-counts. Leave it unset unless you want the log noise.
## Username Generation
**Provisioned resources are named by the order processor, not by this plugin.**
`_get_resource_backend_id()` in the core produces
`f"{allocation_prefix}{resource_slug}".lower()`, and Waldur caps every slug at 10
characters (`SLUG_NAME_LIMIT`), appending `-2`, `-3`, … on collision. So a resource
named `cust-0-proj-0-ceph-s3-of` becomes the uid `cust-0-pro`.
**Format**: `{allocation_prefix}{resource_slug}` — **Example**: `cust-0-pro`
This is the only naming scheme the plugin has. A second one — `user_prefix`,
`slug_separator`, `max_username_length` and a `create_resource()` that read them —
existed alongside it and was never reached, since the order processor calls
`create_resource_with_id()`. It has been removed; an offering still carrying those
three keys is unaffected, they are simply ignored.
## Usage Reporting
**Croit flavour only, and it needs its own backend.** Set
```yaml
reporting_backend: "croit_usage"
```
Metering reads croit's statistics subsystem, which has no RadosGW equivalent, so
it lives in a separate backend class rather than as a method that works on one
flavour and fails on the other. `croit_usage` refuses to start on a
radosgw-flavoured offering.
Leaving `reporting_backend` at `ceph_s3` reports **nothing** — deliberately, not
zeros. A zero is a legitimate usage value and would overwrite the period's
accrued total; silence leaves the last good figure in place.
Storage is billed in **GB-days** — the area under the storage curve over the
billing period, not a reading taken at report time. Object counts are not billed.
Usage is metered **per resource**, not per key: the series is the S3 user's, so
the resource's two access keys never enter the calculation and rotating one
cannot change a bill.
### Where the number comes from
`GET /api/stats?graph=s3-user-data&template-s3-user-name=` returns croit's
per-user storage series as `{"t": unix seconds, "v": bytes}` datapoints at 180 s
native resolution. Each pass asks for the period so far and integrates:
```text
GB-days = Σ (bytes_i / unit_factor) × (t_i+1 − t_i) / 86400
```
Each datapoint is one rectangle — the reading, held until the next sample. A null
`v` is missing telemetry, so the previous reading is carried across it; dropping
the interval would bill it at zero and turn a metrics outage into a silent
discount.
Recomputed from the period start every time rather than accumulated, so the value
is absolute: reporting is idempotent, and an agent that was down for two days
returns the correct figure on its next pass with no catch-up logic. It also only
rises within a period, so Waldur's anomaly detection stays useful and
`supports_decreasing_usage` stays at the default `False`.
### Why GB-days rather than GB
Waldur bills a usage component as a flat `unit_price × quantity` — the `PER_DAY`
proration in invoicing applies only to *fixed* components. So for a price list
denominated per GB per day, the days have to be inside the quantity. Reporting
plain GB against a per-day price under-bills by roughly the number of days in the
month.
### Precision
The integral is computed in `Decimal` and rounded half-up to two places, which is
what the reporter's `"%.2f"` wire format preserves. The report leaves the backend
as plain floats, like every other plugin.
### Report Format
The reporter reads `TOTAL_ACCOUNT_USAGE` and skips any resource whose report
lacks it. There is exactly one S3 user per resource, so the account total *is*
that user's usage; per-user entries would key on Waldur offering users, which
this backend does not manage.
A resource whose series cannot be read is **absent** from the report rather than
present with a zero — zero is a valid usage value and would overwrite the
period's accrued total.
```json
{
"cust-0-pro": {
"TOTAL_ACCOUNT_USAGE": {
"s3_storage": 3100.0
}
}
}
```
Values are plain numbers already in Waldur units, with `unit_factor` applied —
not `{"usage": n}` wrappers.
## Resource Metadata
Each S3 user resource exposes comprehensive metadata:
### S3 Connection
Credentials are **not** in resource metadata. Each resource owns two S3 access keys, stored
encrypted in Waldur and revealed or rotated per key from the portal (see
`waldur-mastermind/docs/resource-api-keys.md`). Metadata carries only the non-secret
connection info, and the S3 endpoint is also published as a resource access endpoint:
```json
{
"s3_endpoint": "https://s3.example.com",
"s3_region": "default",
"s3_user": "cust-0-pro"
}
```
These are deliberately **flat** keys. An offering's *Getting started* text is a template
interpolating `{backend_metadata_}` one level deep, so a nested block would render as
`[object Object]`. Flat keys let a provider write usable instructions once, for example:
```text
Configure your S3 client:
```aws --endpoint-url {backend_metadata_s3_endpoint} s3 ls```
Your access key is on the **API keys** tab — click Reveal for the secret.
```
The agent mints both halves of each pair, applies them to the S3 user, and only then
reports them to Waldur — so a stored key is always one RadosGW already accepts. Rotation
replaces the access key as well as the secret, applying the new pair before dropping the
old one, so the resource's other key keeps working throughout.
**Every credential that works is one Waldur can rotate.** Two things would otherwise
break that:
- *RadosGW mints its own key when a user is created*, and Waldur never sees its secret.
It is deleted right after the user is created, while it is that user's only key and
before anyone holds credentials. This happens only on the branch that actually created
the user. An existing uid is adopted with its keys left in place at provisioning time,
but they are not in Waldur's known set, so the resource's first rotation prunes them.
- *A rotation whose reply to Waldur is lost* has already replaced the access key at the
backend, so re-issuing it rotates from a client_id croit no longer has and would leave
the intermediate key live and invisible. Each rotation therefore receives the resource's
known client_ids and drops anything outside that set. If Waldur cannot be listed the set
is `None` — unknown, so nothing is pruned; treating it as empty would delete every
credential the resource has.
**Known limitation:** croit's create-key endpoint takes the secret as a query parameter
(`PUT /s3/users/{uid}/keys/{accessKey}?secretKey=…`), so it appears in croit's access log.
The bulk alternative (`PUT /s3/users/{uid}/keys`) keeps the secret in the body but replaces
the user's entire key set asynchronously, which can drop a sibling key when two rotations
overlap.
### 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
Ordering a ceiling is the only signal needed — there is no enable switch. The
plugin applies the ordered limits as RadosGW quotas:
1. **Create Resource**: apply the ordered ceilings (`max_storage_limit`,
`max_object_limit`) — **on the create path only**; quotas are not re-asserted
afterwards, so an existing resource keeps whatever it was given
2. **Prevent Overages**: the quota is what bounds the tenant, and therefore the
invoice — usage billing itself has no ceiling
### Quota Types
Both are set from the same ordered ceiling:
- **User quota** (`PUT /s3/users/{uid}/quota`): the aggregate cap across everything
the user owns. This is the one that bounds a tenant — croit exposes no way to
cap the bucket count, so a per-bucket quota alone bounds nothing
- **Bucket quota** (`PUT /s3/users/{uid}/bucket-quota`): a per-bucket guard
- `maxSize` in bytes (`max_storage_limit` × `unit_factor`), `maxObjects` as a count
### How Safety Limits Work
1. **User Configuration**: Users set `max_storage_limit` and `max_object_limit` via Waldur marketplace form
2. **Resource Options**: Waldur passes these as resource attributes to the site agent
3. **Quota Application**: applied as user and bucket quotas during S3 user creation.
A resource that reaches provisioning with no ceiling is logged as a warning
naming the attributes that were present — an unbounded resource is one with no
bound on its invoice
4. **Usage Billing**: actual consumption is measured and billed separately from the
quota, which is a cap rather than a billing basis

### Offering Configuration
The created Waldur offering will have:
- **Type**: `SITE_AGENT_OFFERING` ("Marketplace.Slurm")
- **Components**: `s3_storage` only (usage-based, billed in GB-days)
- **Options**: `max_storage_limit` and `max_object_limit` for user input (safety limits)
- **Pricing**: €0.0010 per GB-day for storage; objects are not billed
### Order Payload Example
```json
{
"offering": "http://localhost:8000/api/marketplace-public-offerings/{offering_uuid}/",
"project": "http://localhost:8000/api/projects/{project_uuid}/",
"plan": "http://localhost:8000/api/marketplace-public-offerings/{offering_uuid}/plans/{plan_uuid}/",
"attributes": {
"max_storage_limit": 100,
"max_object_limit": 10000
},
"name": "my-s3-storage",
"description": "S3 storage for my application",
"accepting_terms_of_service": true
}
```
## Testing
Run the test suite:
```bash
cd plugins/ceph-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"
label: "My custom metric"
measured_unit: "units"
unit_factor: 1
```
- 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
- **`CroitS3GraphNotFoundError`**: the statistics graph behind usage reporting is missing
- **`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
The uid is `{allocation_prefix}{resource_slug}`, and Waldur already caps the slug at
10 characters — so only `allocation_prefix` is yours to shorten. See Username
Generation.
### Debug Logging
Use standard Python logging configuration or waldur-site-agent logging settings to enable debug output for the plugin modules:
- `waldur_site_agent_ceph_s3.client` - HTTP API interactions
- `waldur_site_agent_ceph_s3.backend` - Backend operations
## Resource Lifecycle
1. **Order Creation**: User submits order with `max_storage_limit` and `max_object_limit`
2. **User Creation**: Plugin creates the S3 user under the backend id the order processor generated
3. **Quota Application**: ceilings applied as user and bucket quotas
4. **Key Provisioning**: Two access keys minted, applied, and reported to Waldur encrypted;
RadosGW's auto-generated key is removed
5. **Usage Tracking**: storage integrated into GB-days per billing period
6. **Limit Updates**: **not supported.** The ceiling is an order attribute, fixed at
creation. Waldur can carry an `update_options` order, but the agent does not act
on `new_options`, and quotas are applied only on the create path — so changing a
ceiling today means terminating and re-ordering
7. **Resource Deletion**: the S3 user is removed — but only once it owns no
buckets. croit refuses to delete a user that still holds data
(`500 Unable to remove user with buckets.`), so termination of a tenant with
data fails until the buckets are emptied and removed. The failure reason
reaches the portal's order history and resource activity log.

### 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
compute, storage, and LLM inference usage data to Waldur. The plugin supports secure OIDC authentication and
optional SOCKS proxy connectivity for accessing DWDI API endpoints from restricted networks.
## Features
- **Multiple Backend Support**: Separate backends for compute, storage, and inference 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 three 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
- **Inference Backend** (`cscs-dwdi-inference`): Reports LLM inference cost per resource
## 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
### Inference Backend
The inference backend queries the DWDI API for LLM inference cost and reports:
- Inference cost per resource, already priced by the warehouse (a `totalCost` value)
- Cost mapped onto a single `token_cost` component, keyed by Waldur resource UUID
Unlike the compute and storage backends — which report raw usage that Waldur then prices — the
inference backend reports a **pre-computed cost**: the DWDI warehouse owns the pricing and Waldur
records the amount as-is.
**API Endpoints Used:**
- `/inference/resource/cost` - Monthly inference cost per resource
## Configuration
### Compute Backend Configuration
```yaml
backend_type: "cscs-dwdi-compute"
backend_settings:
cscs_dwdi_api_url: "https://dwdi.cscs.ch"
cscs_dwdi_client_id: "your_oidc_client_id"
cscs_dwdi_client_secret: "your_oidc_client_secret"
cscs_dwdi_oidc_token_url: "https://auth.cscs.ch/realms/cscs/protocol/openid-connect/token"
cscs_dwdi_oidc_scope: "openid" # Optional
backend_components:
nodeHours:
measured_unit: "node-hours"
unit_factor: 1
accounting_type: "usage"
label: "Node Hours"
cpuHours:
measured_unit: "cpu-hours"
unit_factor: 1
accounting_type: "usage"
label: "CPU Hours"
```
### Storage Backend Configuration
```yaml
backend_type: "cscs-dwdi-storage"
backend_settings:
cscs_dwdi_api_url: "https://dwdi.cscs.ch"
cscs_dwdi_client_id: "your_oidc_client_id"
cscs_dwdi_client_secret: "your_oidc_client_secret"
cscs_dwdi_oidc_token_url: "https://auth.cscs.ch/realms/cscs/protocol/openid-connect/token"
# Storage-specific settings
storage_filesystem: "lustre"
storage_data_type: "projects"
storage_tenant: "cscs" # Optional
# Map Waldur resource IDs to storage paths
storage_path_mapping:
"project_123": "/store/projects/proj123"
"project_456": "/store/projects/proj456"
backend_components:
storage_space:
measured_unit: "GB"
unit_factor: 0.000000001 # Convert bytes to GB
accounting_type: "usage"
label: "Storage Space (GB)"
storage_inodes:
measured_unit: "count"
unit_factor: 1
accounting_type: "usage"
label: "File Count"
```
### Inference Backend Configuration
```yaml
backend_type: "cscs-dwdi-inference"
backend_settings:
cscs_dwdi_api_url: "https://dwdi.cscs.ch"
cscs_dwdi_client_id: "your_oidc_client_id"
cscs_dwdi_client_secret: "your_oidc_client_secret"
cscs_dwdi_oidc_token_url: "https://auth.cscs.ch/realms/cscs/protocol/openid-connect/token"
cscs_dwdi_oidc_scope: "openid" # Optional
backend_components:
token_cost:
measured_unit: "EUR"
unit_factor: 1
accounting_type: "usage"
label: "Inference cost"
```
The warehouse returns a per-resource `totalCost`; the backend divides it by the `token_cost`
component's `unit_factor` (or `unit_factor_reporting`) and reports the result. Because the amount is
already priced by DWDI, set the offering plan's `token_cost` price to 1 so Waldur records the cost
as-is.
## 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 |
| `--dry-run` | Log intended submissions without sending anything to Waldur |
| `--reconcile-stale` | Zero out usage records absent from backend data (see below) |
| `--resource-backend-id` | Process only the resource with this backend ID; repeatable |
### 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
- Backfilling `usage`-billing-type components into past billing periods is only permitted
for **staff** tokens; with a service provider token the Waldur API rejects such
submissions with an HTTP 400 mentioning "backfilling past billing periods"
### Correcting Misreported Months
If a past month holds wrong values (for example usage misattributed across a month
boundary), the loader can rewrite that month from the authoritative backend data.
A staff token is required, since usage-based components are being backfilled.
Two flags exist specifically for corrections:
- `--reconcile-stale` also *zeroes* records that the backend does not report:
resource totals for accounts with no backend data in that month, and per-user
usage rows for users missing from the backend report. Without it, phantom values
in Waldur survive whenever the backend has nothing to overwrite them with.
- `--dry-run` prints every intended submission so the correction can be reviewed
before anything is written.
Recommended sequence:
```bash
# 1. Review the correction for a single affected account first
waldur_site_load_historical_usage \
--config /etc/waldur/cscs-dwdi-config.yaml \
--offering-uuid \
--user-token \
--start-date 2026-01-01 --end-date 2026-01-31 \
--resource-backend-id \
--reconcile-stale --dry-run
# 2. Apply it for that account
waldur_site_load_historical_usage ... --resource-backend-id --reconcile-stale
# 3. Sweep the whole offering for the affected months (dry-run first, then apply)
waldur_site_load_historical_usage \
--config /etc/waldur/cscs-dwdi-config.yaml \
--offering-uuid \
--user-token \
--start-date 2026-01-01 --end-date 2026-01-31 \
--reconcile-stale
```
Caveats:
- Rewriting a past-period usage re-triggers marketplace billing for that record, but
the invoice item is only updated while the month's invoice is still mutable;
otherwise Waldur logs a warning and leaves the invoice untouched. Align with the
billing owner on which behaviour is expected before applying corrections.
- Newly created past-month usage records are stored without a plan period, so they
do not generate retroactive invoice items — the correction is display/reporting
oriented by design.
## Example Configurations

### Test Coverage
The test suite covers:
- Client initialization and configuration
- OIDC authentication flow
- API endpoint calls (mocked)
- Usage data processing
- Error handling scenarios
- Backend initialization and validation
## 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`
**Inference API:**
- `/inference/resource/cost`
## 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/
```

### DigitalOcean plugin for Waldur Site Agent
# DigitalOcean plugin for Waldur Site Agent
This plugin integrates Waldur Site Agent with DigitalOcean using the
`python-digitalocean` SDK. It provisions droplets based on marketplace orders
and exposes droplet metadata back to Waldur.
## Configuration
Example configuration for an offering:
```yaml
offerings:
- name: DigitalOcean VM
waldur_api_url: https://waldur.example.com/api/
waldur_api_token:
waldur_offering_uuid:
backend_type: digitalocean
order_processing_backend: digitalocean
reporting_backend: digitalocean
membership_sync_backend: digitalocean
backend_settings:
token:
default_region: ams3
default_image: ubuntu-22-04-x64
default_size: s-1vcpu-1gb
default_user_data: |
#cloud-config
packages:
- htop
default_tags:
- waldur
backend_components:

measured_unit: MiB
unit_factor: 1
accounting_type: limit
label: RAM
disk:
measured_unit: MiB
unit_factor: 1
accounting_type: limit
label: Disk
```
## 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`.

### Envoy AI Gateway Plugin for Waldur Site Agent
# Envoy AI Gateway Plugin for Waldur Site Agent
This plugin integrates [Envoy AI Gateway](https://aigateway.envoyproxy.io/) with Waldur so that
LLM inference access can be sold, provisioned, metered, and billed through the Waldur marketplace.
It provisions per-customer API keys from marketplace orders and reports usage back to Waldur for
metering and billing. Token/cost budgets are enforced by Waldur (report usage -> mastermind pauses
the resource when a limit is reached -> the agent blocks the key), not by the gateway.
The plugin is Kubernetes-native: API keys live in Kubernetes Secrets that the Envoy Gateway
`SecurityPolicy` reads.
## Features
- **API key lifecycle**: provision, pause, restore, and terminate gateway API keys directly from
Waldur marketplace orders
- **Two-secret pause model**: suspend access at the authentication layer by moving a key between
an *active* and a *blocked* Secret — no key regeneration on restore
- **Usage reporting**: report per-key token usage from a pluggable usage warehouse back to Waldur
for metering and billing
- **In-cluster or external**: run inside the cluster (in-cluster config) or against a kubeconfig
context for local development
## Overview
The plugin exposes two backends that are normally paired on a single composed offering:
- **Management backend** (`envoy`): the `order_processing_backend`. Owns the API key lifecycle
(provision, pause, restore, terminate).
- **Usage reporting backend** (`envoy-usage`): the `reporting_backend`. Reads per-key token usage
from a usage warehouse and submits it to Waldur.
Token pricing itself lives in Waldur: the reporting backend submits raw token counts, and the
offering plan prices them (e.g. €/token). Keys and usage are keyed off a single
`client_id` (the resource's `backend_id`) — provision it once and everything else follows.
For deployments that price usage upstream instead (per-model rates, discounts), the sibling
`cscs-dwdi-inference` reporting backend is the cost-model alternative: it reports a pre-priced
`token_cost` component that Waldur records as-is rather than raw token counts. Pair it in place of
`envoy-usage` when the warehouse — not Waldur — owns pricing.
## Backend Types
### Management Backend (`envoy`)
Envoy Gateway's `SecurityPolicy` authenticates requests against API keys stored as `clientID: key`
entries in a Kubernetes Secret. This backend manages those entries.
**Key lifecycle** — to support pause/restore using only the `client_id`, two Secrets are kept and
entries move between them:
- **create (order)**: generate a `client_id` + random key, add `client_id: key` to the **active**
Secret, and return `client_id` as the `backend_id` (surfacing the key + endpoint on the
resource).
- **pause**: move the entry **active → blocked** — authentication now fails with 401.
- **restore**: move the entry **blocked → active**.
- **terminate**: remove the entry from both Secrets.
**Kubernetes objects touched:** Secrets (`get`/`patch`) in the configured namespace.
**Limit enforcement** — the gateway does not cap usage. The reporting backend submits usage to
Waldur; when a `LIMIT` component's reported usage reaches its limit and the offering sets
`plugin_options.action_on_usage_limit: pause`, mastermind pauses the resource and the agent blocks
the key (active -> blocked Secret). When usage drops back below the limit, the resource is unpaused
and the key is restored.
### Usage Reporting Backend (`envoy-usage`)
A read-only backend that reports per-key token usage from a usage warehouse — any HTTP service
that exposes the endpoints below (for example a small collector that aggregates the gateway's
per-request usage metrics).
**API endpoints used:**
- `GET /usage-month?from=YYYY-MM&to=YYYY-MM&client_id=...` — per-`client_id` usage rows for a
month range; response shape `{"usage": [{"client_id": "...", "input_tokens": N, "output_tokens": N}]}`
- `GET /health` — liveness check used by `ping()`
The backend maps the warehouse's token fields onto the offering's components, reporting only the
components the offering defines. It implements `get_usage_report_for_period()`, so historical
usage can be bulk-loaded with the core `waldur_site_load_historical_usage` command.
## Configuration
The two backends are typically combined on one composed offering and share a single
`backend_settings` block. The keys for each backend are listed separately below, followed by a
combined example.
### Management backend settings (`envoy`)
| Setting | Required | Default | Description |
|---------|----------|---------|-------------|
| `namespace` | yes | — | Namespace holding the api-key Secrets |
| `gateway_url` | yes | — | Public base URL of the gateway, used for the resource endpoint |
| `apikey_secret` | no | `envoy-ai-gateway-apikeys` | Secret the `SecurityPolicy` reads keys from |
| `blocked_secret` | no | `-blocked` | Secret holding paused keys |
| `kubeconfig_path` | no | in-cluster | Path to a kubeconfig; omit to use in-cluster config |
| `kube_context` | no | current | kubeconfig context to target (local/dev) |
### Usage reporting backend settings (`envoy-usage`)
| Setting | Required | Default | Description |
|---------|----------|---------|-------------|
| `api_url` | yes | — | Usage warehouse base URL |
| `api_token` | no | — | Bearer token for the warehouse API |
### Composed offering (both backends)
```yaml
offerings:
- name: "LLM Inference"
order_processing_backend: "envoy"
membership_sync_backend: "envoy" # required for pause/restore (key blocking)
reporting_backend: "envoy-usage"
backend_settings:
# --- management backend (envoy) ---
namespace: "ai-gateway"
gateway_url: "https://ai-gateway.example.com"
apikey_secret: "envoy-ai-gateway-apikeys" # optional, this is the default
blocked_secret: null # optional, defaults to -blocked
kubeconfig_path: null # omit to use in-cluster config
# --- usage reporting backend (envoy-usage) ---
api_url: "http://usage-warehouse:9000"
api_token: null
backend_components:
input_tokens:
measured_unit: "tokens"
accounting_type: "usage"
label: "Input tokens"
output_tokens:
measured_unit: "tokens"
accounting_type: "usage"
label: "Output tokens"
```
The `input_tokens` / `output_tokens` components are the usage meters the reporting backend fills
in; `accounting_type: usage` here is the agent-side metering type. Enforcement is configured on the
Waldur **offering**, not in this file: for a resource to auto-pause, the matching offering
component must be `billing_type: LIMIT` and the offering must set
`plugin_options.action_on_usage_limit: pause` — only `LIMIT` components are checked against their
limit. When reported usage reaches the limit, Waldur pauses the resource and the agent blocks the
key. Blocking runs in the membership-sync loop, so `membership_sync_backend: envoy` must be set
(as above) — without it the agent never blocks the key and the limit is not enforced.
## Prerequisites
- **Both Secrets must pre-exist.** Create empty `apikey_secret` and `-blocked`
Secrets in `namespace` as part of the deployment; the plugin patches entries into them but does
not create the Secrets themselves.
- **RBAC.** The agent's ServiceAccount needs the permissions below.
### Kubernetes RBAC
```yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
name: waldur-site-agent
namespace: ai-gateway
rules:
- apiGroups: [""]
resources: ["secrets"]
verbs: ["get", "patch"]
```
## Usage Reporting
The `envoy-usage` backend is read-only. It implements usage reporting and resource pull, but does
not create, pause, restore, or otherwise manage resources (those belong to the `envoy` backend).
Usage is reported for the current month via `_get_usage_report()` and for arbitrary past months
via `get_usage_report_for_period()`, which the historical loader uses.
### Per-key requests, per-resource billing
A resource owns several API keys, but usage is attributed **per resource** — otherwise
rotating a key would split a tenant's bill in two.
The gateway forwards `x-client-id` per key (`-`), and the rollup
happens at the **usage-shipper** (a Vector pipeline): its `remap` transform strips the
`-` suffix, so usage lands under the resource's `backend_id`:
```coffee
# usage-shipper (Vector) remap transform
cid = replace(cid, r'-\d+$', "")
```
`envoy-usage` then queries the warehouse by `resource_backend_id` unchanged — no key
enumeration. Pause, restore and terminate are the opposite: they act on the gateway Secret
rather than on usage, so they fan out to **every** client-id the resource owns.
## Installation
The plugin is discovered automatically once `waldur-site-agent-envoy-ai-gateway` is installed
alongside `waldur-site-agent`.
### UV Workspace Installation
```bash
# Install all workspace packages including this plugin
uv sync --all-packages
```
### Manual Installation
```bash
# From source
pip install -e plugins/envoy-ai-gateway/
```
## Testing
```bash
# Run all plugin tests
uv run pytest plugins/envoy-ai-gateway/tests/
# Run with coverage
uv run pytest plugins/envoy-ai-gateway/tests/ --cov=waldur_site_agent_envoy_ai_gateway
```
The suite covers key lifecycle (provision/pause/restore/terminate), the usage warehouse client, and
usage report mapping — all with the Kubernetes and HTTP clients mocked, so no live cluster or
warehouse is required.
## Troubleshooting
### Keys are provisioned but requests are rejected
- Confirm the `SecurityPolicy` reads the Secret named by `apikey_secret`.
- Check the key landed in the **active** Secret, not the blocked one (`kubectl get secret ...`).
- Verify the request sends the API key the order surfaced.
### Usage reports are empty or zero
- Check the warehouse is reachable: the backend's `ping()` hits `GET /health`.
- Confirm the warehouse returns rows keyed by the same `client_id` the gateway authenticates with
(the resource `backend_id`).
- Confirm the offering's `backend_components` are named to match the warehouse fields
(`input_tokens`, `output_tokens`).
### RBAC errors on Secrets
- Grant `get`/`patch` on Secrets in `namespace` (see
[Kubernetes RBAC](#kubernetes-rbac)).

### Key Classes
- **`EnvoyAIGatewayBackend`** (`envoy`): management backend — provisions and blocks/unblocks keys
- **`EnvoyAIGatewayClient`**: Kubernetes client for api-key Secrets
- **`EnvoyUsageReportingBackend`** (`envoy-usage`): reports token usage to Waldur
- **`EnvoyUsageClient`**: HTTP client for the usage warehouse
### Registered Entry Points
Each backend registers under the same name across three groups (`waldur_site_agent.backends`,
`waldur_site_agent.component_schemas`, `waldur_site_agent.backend_settings_schemas`):
- `envoy` — management backend + its schemas
- `envoy-usage` — reporting backend + its schemas
### Extension Points
- **Different usage warehouse**: implement the two HTTP endpoints, or subclass `EnvoyUsageClient`
to match another warehouse's API.
- **Cost-based reporting**: report a priced `token_cost` component instead of raw token counts if
pricing should live outside Waldur — the sibling `cscs-dwdi-inference` backend implements exactly
this model and can be used as the `reporting_backend` in place of `envoy-usage`.

### Key Mapping Rules
1. **Waldur Resource** → **Harbor Project** (1:1)
- Each Waldur resource creates a separate Harbor project
- Provides complete isolation between different registry resources
- Project names: `{allocation_prefix}{resource_slug}`
2. **Waldur Project** → **OIDC Group** (1:1)
- One OIDC group per Waldur project for access control
- All project team members get access to ALL Harbor projects within the Waldur project
- Group names: `{oidc_group_prefix}{project_slug}`
3. Storage Management
- Each Harbor project gets individual storage quota
- Quotas set based on Waldur resource limits
- Usage reported back to Waldur for billing
## Installation
1. Install the plugin alongside waldur-site-agent:
```bash
# From the workspace root
uv sync --all-packages
```
1. Configure the plugin in your waldur-site-agent configuration file
## Configuration
Add the Harbor backend configuration to your `waldur-site-agent-config.yaml`:
```yaml
offerings:
harbor-registry:
backend_type: harbor
backend_settings:
# Harbor instance URL
harbor_url: "https://harbor.example.com"
# Robot account credentials (ensure robot has sufficient permissions)
robot_username: "robot$waldur-agent"
robot_password: "your-robot-password-here"
# Default storage quota in GB for new projects
default_storage_quota_gb: 10
# Naming prefixes
oidc_group_prefix: "waldur-" # OIDC groups: waldur-{project_slug}
allocation_prefix: "waldur-" # Harbor projects: waldur-{resource_slug}
# Harbor project role for OIDC groups
# 1=Admin, 2=Developer (recommended), 3=Guest, 4=Maintainer
project_role_id: 2
backend_components:
storage:
measured_unit: "GB"
accounting_type: "limit"
label: "Container Storage"
unit_factor: 1
# Waldur API settings
api_url: "https://waldur.example.com/api/"
api_token: "your-waldur-api-token"
# Offering UUID in Waldur
offering_uuid: "harbor-offering-uuid"
```
### Robot Account Permissions
**Critical**: The Harbor robot account must have the following permissions:
- ✅ **Project creation** (`POST /api/v2.0/projects`)
- ✅ **Project deletion** (`DELETE /api/v2.0/projects/{id}`) - **REQUIRED for proper resource lifecycle**
- ✅ **Quota management** (`GET/PUT /api/v2.0/quotas`)
- ✅ **User group management** (`GET/POST /api/v2.0/usergroups`)
- ✅ **Project member management** (`GET/POST/DELETE /api/v2.0/projects/{id}/members`)
**✅ Verified**: All operations including project deletion are working with proper system-level robot account permissions.
## Harbor Setup
### 1. Create Robot Account
1. Login to Harbor as admin
2. Navigate to Administration → Robot Accounts
3. Create a new robot account with **system-level permissions**:
- **Level**: System (not project-specific)
- **Permissions**:
- Project: Create, Read, Update, **Delete**
- Resource: Create, Read, Update
- Member: Create, Read, Update, Delete
- Quota: Read, Update
4. Save the credentials for configuration
**Note**: The robot account needs **system-level** permissions to delete projects.
Project-level robot accounts cannot delete their own projects.
### 2. Configure OIDC Authentication
1. Navigate to Administration → Configuration → Authentication
2. Set Auth Mode to "OIDC"
3. Configure OIDC provider settings:
- OIDC Endpoint: Your identity provider URL
- OIDC Client ID: Harbor client ID in your IdP
- OIDC Client Secret: Harbor client secret
- OIDC Scope: `openid,email,profile,groups`
- Group Claim Name: `groups` (or your IdP's group claim)
### 3. Configure Storage Quotas
1. Navigate to Administration → Configuration → System Settings
2. Set appropriate global storage quota limits
3. Individual project quotas will be managed by the agent
## Usage
### Running the Agent
```bash
# Process orders (create/delete Harbor projects)
uv run waldur_site_agent -m order_process -c config.yaml
# Report usage back to Waldur
uv run waldur_site_agent -m report -c config.yaml
# Synchronize memberships (OIDC group management)
uv run waldur_site_agent -m membership_sync -c config.yaml
```
### Systemd Service
Create a systemd service for automated operation:
```ini
[Unit]
Description=Waldur Harbor Agent - Order Processing
After=network.target
[Service]
Type=simple
User=waldur
ExecStart=/usr/local/bin/waldur_site_agent -m order_process -c /etc/waldur/harbor-config.yaml
Restart=on-failure
RestartSec=60
[Install]
WantedBy=multi-user.target
```
## API Operations
The plugin implements the following Harbor API operations:
### ✅ Project Management (Fully Working)
- ✅ Create project with minimal payload
- ✅ Get project details and metadata
- ✅ List all projects
- ✅ **Delete project (complete resource lifecycle)**
### ✅ Storage Quota Management (Fully Working)
- ✅ Set project storage quotas
- ✅ Update project storage quotas
- ✅ Query current quota usage
- ✅ Report storage consumption for billing
### ✅ OIDC Group Management (Fully Working)
- ✅ Create OIDC groups
- ✅ Assign groups to projects with specified roles (Admin/Developer/Guest/Maintainer)
- ✅ List existing user groups
- ✅ Search for specific groups
### ✅ Usage Reporting (Fully Working)
- ✅ Query project storage usage via quota API
- ✅ Report repository counts
- ✅ Track storage consumption for Waldur billing
- ✅ Get project metadata and statistics
### 🔄 Supported Waldur Operations
- ✅ **order_process**: Create/update Harbor projects and quotas
- ✅ **report**: Report storage usage back to Waldur
- ✅ **membership_sync**: Manage OIDC group memberships
- ✅ **diagnostics**: Health checks and connectivity testing
- ❌ **pause**: Not supported (Harbor has no pause concept, returns False)
## Testing
Run the test suite:
```bash
# Run all Harbor plugin tests
uv run pytest plugins/harbor/tests/ -v
# Run with coverage
uv run pytest plugins/harbor/tests/ --cov=waldur_site_agent_harbor
```
## Troubleshooting
### ✅ Known Issues & Solutions
#### 1. **CSRF Token Errors (SOLVED)**
**Symptom**: `403 Forbidden - CSRF token not found in request`
**Root Cause**: Harbor's session-based authentication requires CSRF tokens for persistent sessions.
**✅ Solution**: The plugin now uses direct HTTP requests with authentication tuples instead of
persistent sessions, which bypasses CSRF requirements entirely.
**Technical Details**:
```python
# OLD (caused CSRF issues)
session = requests.Session()
session.headers.update({"Authorization": "Basic ..."})
response = session.post(url, json=data)
# NEW (works perfectly)
auth = (username, password)
response = requests.post(url, auth=auth, json=data)
```
#### 2. **Robot Account Permissions**
**Symptoms**:
- Can list projects but cannot create them
- Can create projects but cannot set quotas
- Cannot create OIDC groups
**✅ Solution**: Ensure robot account has system-level permissions:
1. Login to Harbor as admin
2. Go to Administration → Robot Accounts
3. Edit your robot account
4. Grant these **system-level** permissions:
- **Project**: Create, Read, Update, **Delete**
- **Resource**: Create, Read, Update
- **Member**: Create, Read, Update, Delete
- **Quota**: Read, Update
**Critical**: Without project deletion permissions, Harbor projects will accumulate when Waldur resources
are terminated, leading to storage waste and potential quota issues.
### Common Issues
1. Authentication Failures
- ✅ Verify robot account credentials in configuration
- ✅ Test connectivity: `curl -u "robot\$user:pass" https://harbor.example.com/api/v2.0/health`
- ✅ Ensure Harbor API v2.0 is enabled
2. OIDC Group Issues
- ✅ Verify OIDC configuration in Harbor (Administration → Configuration → Authentication)
- ✅ Check group claim configuration (`groups` is common)
- ✅ Ensure OIDC provider is properly configured
3. Storage Quota Problems
- ✅ Check global quota settings in Harbor (Administration → Configuration → System Settings)
- ✅ Verify project-specific quotas: `curl -u "robot\$user:pass" https://harbor.example.com/api/v2.0/quotas`
- ✅ Monitor Harbor system storage availability
### Debugging
#### Enable Debug Logging
```yaml
# In waldur-site-agent config
logging:
level: DEBUG
format: "%(asctime)s - %(name)s - %(levelname)s - %(message)s"
```
#### Test Harbor Client Directly
```python
from waldur_site_agent_harbor.client import HarborClient
client = HarborClient("https://harbor.example.com", "robot$user", "password")
# Test connectivity
print("Ping:", client.ping())
# List projects
projects = client.list_resources()
print("Projects:", [p.name for p in projects])
# Test permissions
try:
# This should work if permissions are correct
group_id = client.create_user_group("test-group")
print("Group created:", group_id)
except Exception as e:
print("Permission issue:", e)
```
#### Check Logs
```bash
# For systemd deployments
journalctl -u waldur-harbor-agent -f --since "1 hour ago"
# For direct execution
tail -f /var/log/waldur-site-agent.log
```
### Verification Commands
Test robot account permissions manually:
```bash
# Test authentication
curl -u "robot\$username:password" https://harbor.example.com/api/v2.0/health
# Test project listing
curl -u "robot\$username:password" https://harbor.example.com/api/v2.0/projects
# Test quota access
curl -u "robot\$username:password" https://harbor.example.com/api/v2.0/quotas
# Test group management
curl -u "robot\$username:password" https://harbor.example.com/api/v2.0/usergroups
# Test project deletion permissions (CRITICAL)
# First create a test project
curl -X POST -H "Content-Type: application/json" \
-u "robot\$username:password" \
-d '{"project_name":"deletion-test","metadata":{"public":"false"}}' \
https://harbor.example.com/api/v2.0/projects
# Then try to delete it (should return 200/204, not 403)
# Get project ID first, then delete
curl -X DELETE -u "robot\$username:password" \
https://harbor.example.com/api/v2.0/projects/{project_id}
```
### Expected Results
- ✅ **200/201** for creation operations
- ✅ **200** for read operations
- ✅ **200/204** for update operations
- ✅ **200/204** for deletion operations
- ❌ **403 Forbidden** indicates insufficient permissions

### Waldur Site Agent - K8s UT Namespace Plugin
# Waldur Site Agent - K8s UT Namespace Plugin
This plugin enables integration between Waldur Site Agent and Kubernetes clusters for managing
`ManagedNamespace` custom resources (CRD: `provisioning.hpc.ut.ee/v1`) with optional Keycloak
RBAC group integration.
## Features
- **ManagedNamespace Lifecycle**: Creates, updates, and deletes `ManagedNamespace` custom resources
- **Resource Quotas**: Sets CPU, memory, storage, and GPU limits as namespace quotas
- **Role-Based Access Control**: Creates 3 Keycloak groups per namespace (admin, readwrite, readonly)
- **Waldur Role Mapping**: Maps Waldur roles to namespace access levels automatically
- **User Management**: Adds/removes users from Keycloak groups, reconciles role changes
- **Usage Reporting**: Reports actual resource consumption from K8s ResourceQuota or quota allocations
- **Namespace Labels & Annotations**: Configurable labels and annotations propagated to created namespaces
- **Status Monitoring**: Parses operator Ready condition and exposes readiness in Waldur metadata
- **Configurable User Identity**: Choose which user attribute (email, civil_number, etc.) populates CR user fields
- **Namespace Name Validation**: Validates generated names against RFC 1123 before CR creation
- **Status Operations**: Supports downscale (minimal quota), pause (zero quota), and restore
## Architecture
The plugin follows the Waldur Site Agent plugin architecture and consists of:
- **K8sUtNamespaceBackend**: Main backend implementation that orchestrates namespace and user management
- **K8sUtNamespaceClient**: Handles Kubernetes API operations for `ManagedNamespace` CRs
- **KeycloakClient**: Manages Keycloak groups and user memberships (shared package)
### Role Mapping
Waldur roles are mapped to namespace access levels. The default mapping is:
| Waldur Role | Namespace Role |
|-------------|----------------|
| `manager` | `admin` |
| `admin` | `admin` |
| `member` | `readwrite` |
This mapping is configurable via the `role_mapping` setting in `backend_settings`.
Custom entries are merged with the defaults, so you only need to specify overrides or additions:
```yaml
backend_settings:
role_mapping:
observer: "readonly"
member: "readonly" # override the default
```
Users whose Waldur role is not in the mapping fall back to `default_role` (default: `readwrite`).
### Component Mapping
Waldur component keys are mapped to Kubernetes quota fields. The default mapping is:
| Waldur Component | K8s Quota Field | Unit Format |
|------------------|-----------------|-------------|
| `cpu` | `cpu` | Integer |
| `ram` | `memory` | `{value}Gi` |
| `storage` | `storage` | `{value}Gi` |
| `gpu` | `gpu` | Integer |
This mapping is configurable via the `component_quota_mapping` setting in `backend_settings`.
Custom entries are merged with the defaults:
```yaml
backend_settings:
component_quota_mapping:
vram: "nvidia.com/vram"
```
## Installation
Install the plugin using uv:
```bash
uv sync --all-packages
```
The plugin will be automatically discovered via Python entry points.
## Setup Requirements
### Kubernetes Cluster Setup
1. **Kubernetes Cluster**: Accessible cluster with the `ManagedNamespace` CRD installed
(`provisioning.hpc.ut.ee/v1`)
2. **Access Method**: Either a kubeconfig file or in-cluster service account
3. **CR Namespace**: A namespace where `ManagedNamespace` CRs will be created
(default: `waldur-system`)
### Keycloak Setup (Optional)
Required for RBAC group integration:
1. **Keycloak Server**: Accessible Keycloak instance
2. **Target Realm**: Where user accounts and groups will be managed
3. **Service User**: User with group management permissions
#### Creating Keycloak Service User
1. Login to Keycloak Admin Console
2. Select Target Realm
3. Create User:
- **Username**: `waldur-site-agent-k8s`
- **Email Verified**: Yes
- **Enabled**: Yes
4. **Set Password**: In Credentials tab (temporary: No)
5. **Assign Roles**: In Role Mappings tab
- **Client Roles** -> `realm-management`
- **Add**: `manage-users` (sufficient for group operations)
### Waldur Marketplace Setup
1. **Marketplace Offering**: Created with appropriate type (e.g., `Marketplace.Basic`)
2. **Components**: Configured via `waldur_site_load_components`
3. **Offering State**: Must be `Active` for order processing

## Usage
### Running the Agent
Start the agent with your configuration file:
```bash
uv run waldur_site_agent -c k8s-namespace-config.yaml -m order_process
```
### Diagnostics
Run diagnostics to check connectivity:
```bash
uv run waldur_site_diagnostics -c k8s-namespace-config.yaml
```
### Supported Agent Modes
- **order_process**: Creates and manages ManagedNamespace CRs based on Waldur resource orders
- **membership_sync**: Synchronizes user memberships between Waldur and Keycloak groups
- **report**: Reports namespace quota allocations to Waldur
## Resource Lifecycle
### Namespace Creation
When a Waldur resource order is processed:
1. Resource slug is validated (required for naming)
2. Three Keycloak groups are created: `ns_{slug}_admin`, `ns_{slug}_readwrite`, `ns_{slug}_readonly`
3. A `ManagedNamespace` CR is created with quota and group references in the spec
4. The namespace name is `{namespace_prefix}{slug}` (e.g., `waldur-my-project`)
5. If CR creation fails, Keycloak groups are cleaned up (compensating transaction)
### Namespace Deletion
When a Waldur resource termination order is processed:
1. The `ManagedNamespace` CR is deleted
2. All 3 Keycloak groups are deleted
### Limit Updates
When resource limits are updated in Waldur:
1. Limits are converted to K8s resource quantities
2. The CR's `spec.quota` is patched with the new values
### User Management
When users are added to a Waldur resource:
1. Each user's Waldur role is mapped to a namespace role (admin/readwrite/readonly)
2. User is looked up in Keycloak
3. User is removed from any incorrect role groups (role reconciliation)
4. User is added to the correct role group
#### Direct CR User Sync
When `sync_users_to_cr` is enabled, user identities from Waldur are written directly to the
ManagedNamespace CR's `adminUsers`, `rwUsers`, and `roUsers` fields.
The managed-namespace-operator then creates RoleBindings with these identities as
User subjects (optionally prefixed with `CONTROLLER_USER_PREFIX` on the operator side).
The `cr_user_identity_field` setting controls which user attribute is used as the
identity value. The default is `email`, but any attribute exposed by the offering's
user attribute config can be used (e.g., `civil_number`, `username`).
Each user's Waldur role is mapped to a namespace role using the same
`role_mapping` configuration (see [Role Mapping](#role-mapping)), and the
identity value is placed in the corresponding CR field:
| Namespace Role | CR Field |
|---|---|
| `admin` | `adminUsers` |
| `readwrite` | `rwUsers` |
| `readonly` | `roUsers` |
On each membership sync cycle, the **full current set** of team members from
Waldur is written to the CR. Users removed from the Waldur project team are
automatically removed from the CR on the next sync, because empty lists are
sent for roles with no members.
This can be used **alongside** Keycloak groups (both mechanisms populate the
same RoleBindings) or **without** Keycloak (`keycloak_enabled: false`) for
deployments that rely solely on OIDC-based authentication.
```yaml
backend_settings:
sync_users_to_cr: true
cr_user_identity_field: "civil_number" # or "email", "username", etc.
cr_user_identity_lowercase: true # optional, lowercase the value
keycloak_enabled: false # optional, can also be true for dual mode
```
The chosen field must be enabled in the offering's user attribute config
(`expose_civil_number: true`) in Waldur. Users missing the configured
attribute are skipped with a warning log.
When `cr_user_identity_lowercase` is enabled, the identity value is
lowercased before writing to the CR (e.g., `EE12345678901` becomes
`ee12345678901`). This is useful when OIDC subject matching is
case-sensitive and the identity source has mixed case.
When users are removed:
1. User is removed from all 3 Keycloak groups
### Usage Reporting
The plugin reports actual resource consumption by reading `ResourceQuota.status.used`
from the managed namespace. The K8s service account needs `get` permission on
`resourcequotas` in the target namespaces for this to work. If the ResourceQuota is
not accessible, usage is reported as zeros.
Usage values are converted back to Waldur component units using the reverse of
the component quota mapping (e.g., K8s `limits.memory: 4Gi` → Waldur `ram: 4`).
### Namespace Labels & Annotations
Labels and annotations configured in `backend_settings` are included in the
ManagedNamespace CR spec. The operator propagates them to the actual namespace.
This is useful for cluster policies (e.g., Kyverno requiring a `tenant` label):
```yaml
backend_settings:
namespace_labels:
tenant: "waldur"
cost-center: "HPC-001"
namespace_annotations:
description: "Managed by Waldur Site Agent"
```
### Status Operations
| Operation | Effect |
|-----------|--------|
| Downscale | Quota set to minimal: cpu=1, memory=1Gi, storage=1Gi |
| Pause | Quota set to zero: cpu=0, memory=0Gi, storage=0Gi |
| Restore | No-op (limits should be re-set via a separate update order) |
## Error Handling
- Kubernetes connectivity issues are logged and raised as `BackendError`
- Keycloak initialization failure logs a warning; user management operations become no-ops
- CR creation failure triggers automatic Keycloak group cleanup
- Missing users in Keycloak are logged as warnings and skipped
- Missing backend ID on deletion is logged and skipped gracefully

### LDAP Username Management Plugin for Waldur Site Agent
# LDAP Username Management Plugin for Waldur Site Agent
Provisions POSIX users and groups in an LDAP directory when Waldur offering
members need local accounts on an HPC site. Handles the full user lifecycle:
account creation, access group membership, optional VPN password generation,
and welcome email delivery.

## Features
- **POSIX User Provisioning**: Creates `posixAccount` entries with personal groups,
auto-allocated UID/GID from configurable ranges
- **Username Generation**: Multiple strategies — `first_initial_lastname` (`jsmith`),
`first_letter_full_lastname` (`j.smith`), `firstname_dot_lastname` (`john.smith`),
`firstname_lastname` (`johnsmith`), or passthrough `waldur_username`
- **Collision Resolution**: Expands first-name prefix before falling back to numeric
suffixes (`j.smith` → `jo.smith` → `john.smith` → `j.smith2`)
- **Access Groups**: Automatically adds new users to configured LDAP groups
(e.g., VPN access, GPU access) with `memberUid` or `member` (DN-based) attributes
- **VPN Password Generation**: Optional cryptographically random password stored in
`userPassword` attribute
- **Welcome Email**: Templated email via SMTP with account credentials, delivered
on user creation (opt-in)
- **Profile Sync**: Updates LDAP attributes (`givenName`, `sn`, `cn`, `mail`) from
Waldur user profiles
- **User Deactivation**: Configurable removal or retention of LDAP entries when
users leave the offering

### waldur-site-agent-nextcloud
# waldur-site-agent-nextcloud
Nextcloud plugin for [Waldur Site Agent](https://github.com/waldur/waldur-site-agent).
Users purchase storage plans in Waldur and automatically receive access to a shared
Nextcloud Group Folder. Login is via Keycloak OIDC.
## How it works
- Each Waldur resource → a Nextcloud **Group** + **Group Folder** (with quota from the plan)
- Users added to the resource → added to the Nextcloud group → can access the folder
- Usage is reported as Group Folder bytes used
## Prerequisites
Install and enable in Nextcloud admin:
- **User OIDC** app (`user_oidc`) — configure to point at your Keycloak realm
- **Group Folders** app (`groupfolders`)
In the OIDC provider settings, set the user ID attribute to `preferred_username`
(matches the Keycloak username that the site-agent uses when calling the OCS API).
## Configuration example
```yaml
offerings:
- name: "Nextcloud Storage"
waldur_api_url: "https://sky.sigma2.no/api/"
waldur_api_token: "${SITE_AGENT_API_TOKEN}"
waldur_offering_uuid: "${OFFERING_UUID}"
backend_type: "nextcloud"
order_processing_backend: "nextcloud"
membership_sync_backend: "nextcloud"
reporting_backend: "nextcloud"
# STOMP is strongly recommended for Nextcloud. On event-based deployments
# the agent retries the team-member fetch to avoid a race where the
# create-order event arrives before Waldur commits the initial membership.
stomp_enabled: true
# stomp_membership_sync_enabled: false # uncomment to keep HTTP polling for
# # membership sync even with STOMP on
backend_settings:
nextcloud_url: "https://nextcloud.example.com"
admin_username: "admin"
admin_password: "${NEXTCLOUD_ADMIN_PASSWORD}"
group_prefix: "waldur-" # prefix for auto-created groups
default_storage_quota_gb: 25 # fallback if plan has no storage limit (GiB)
allow_resharing: false # allow users to reshare folder contents
backend_components:
storage:
# Quota values are in GiB (1 GiB = 1024³ bytes), consistent with how
# Nextcloud labels storage in its UI.
measured_unit: "GiB"
accounting_type: "limit"
label: "Storage"
unit_factor: 1
```
### Backend settings reference
| Key | Default | Description |
|-----|---------|-------------|
| `nextcloud_url` | *(required)* | Base URL of the Nextcloud instance |
| `admin_username` | *(required)* | Admin account for OCS API calls |
| `admin_password` | *(required)* | Admin password (use env var substitution) |
| `group_prefix` | `"waldur-"` | Prefix prepended to every auto-created group name |
| `default_storage_quota_gb` | `25` | Fallback quota (GiB) when the Waldur plan has no storage limit |
| `allow_resharing` | `false` | If `false`, group members cannot reshare folder contents |
### STOMP settings reference
| Key | Default | Description |
|-----|---------|-------------|
| `stomp_enabled` | `false` | Enable STOMP event-driven processing |
| `stomp_membership_sync_enabled` | `null` | Inherits `stomp_enabled`. Set `false` to keep HTTP polling for membership. |
#### `team_fetch_attempts` (backend-level, non-configurable)
The Nextcloud backend sets `team_fetch_attempts = 4` internally.
On order-processing paths (including STOMP create-order events) the event can
arrive before Waldur has committed the initial team membership row. The agent
retries the team-member fetch up to 4 times (with a 3 s delay between
attempts) if the list comes back empty. Other backends default to 1 (no
retry); this higher value is specific to Nextcloud's create-order path.
Note: the retry only helps when the team is entirely absent. A non-empty
but stale team (new member not yet committed) breaks on the first attempt.

### Waldur Site Agent OKD Plugin
# Waldur Site Agent OKD Plugin
This plugin enables Waldur Site Agent to manage OKD/OpenShift projects and resources, providing integration between
Waldur and OKD/OpenShift clusters.
## Features
- Automatic project/namespace creation for Waldur resources
- Resource quota management (CPU, memory, storage, pod limits)
- User access control through RoleBindings
- Resource usage reporting
- Project lifecycle management (create, pause, restore, delete)
## Installation
Install the plugin alongside the core waldur-site-agent package:
```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:
cpu:
measured_unit: Core
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
e.g. 'ACME Corp']
WP[Project
e.g. 'Web Development']
WR[Resource/Allocation
e.g. 'Production Environment']

WR -.->|Sets limits| ORQ
style WR fill:#e1f5fe
style ON fill:#c8e6c9
style ORQ fill:#fff9c4
style ORB fill:#ffccbc
```
### Object Mapping Details
#### 1. Namespace Creation
Waldur resources are mapped to OKD namespaces with a hierarchical naming convention:
| Waldur Object | OKD Namespace Pattern | Example |
|---------------|----------------------|---------|
| Customer Resource | `{prefix}org-{customer_slug}` | `waldur-org-acme` |
| Project Resource | `{prefix}proj-{project_slug}` | `waldur-proj-webdev` |
| Allocation Resource | `{prefix}alloc-{allocation_slug}` | `waldur-alloc-prod-env` |
#### 2. Resource Quotas
Waldur resource limits are translated to Kubernetes ResourceQuotas:
| Waldur Component | OKD ResourceQuota Field | Example |
|-----------------|------------------------|---------|
| CPU (Cores) | `requests.cpu`, `limits.cpu` (2x requests) | requests: `4`, limits: `8` |
| Memory (GB) | `requests.memory`, `limits.memory` (2x requests) | requests: `16Gi`, limits: `32Gi` |
| Storage (GB) | `requests.storage` | `100Gi` |
| Pod Count | `pods` | `50` |
> **Note:** `limits.cpu` and `limits.memory` are automatically set to 2x the request values to allow bursting.
#### 3. User Access Mapping
Waldur user roles are mapped to OpenShift RoleBindings:
| Waldur Role | OpenShift ClusterRole | Permissions |
|------------|----------------------|-------------|
| Owner | `admin` | Full namespace administration |
| Manager | `edit` | Create/modify resources |
| Member | `view` | Read-only access |
#### 4. Metadata and Annotations
Waldur metadata is preserved in OKD annotations:
```yaml
metadata:
name: waldur-alloc-prod-env
annotations:
openshift.io/description: "Production Environment"
openshift.io/display-name: "Production Environment"
waldur/organization: "waldur-org-acme"
waldur/parent: "waldur-proj-webdev"
```
## OKD/OpenShift Setup
### Authentication Requirements
The plugin requires a service account token with specific permissions to manage OKD/OpenShift
resources. The token must have cluster-level permissions to create and manage projects, namespaces,
resource quotas, and role bindings.
#### Required Permissions
The service account needs the following permissions:
- **Project Management**: Create, delete, and modify OpenShift projects
- **Namespace Management**: Manage Kubernetes namespaces and their metadata
- **Resource Quota Management**: Create and modify resource quotas for namespace limits
- **Role Binding Management**: Assign users to projects with appropriate roles
- **Resource Monitoring**: Query resource usage and project status
### 1. Create Service Account
Create a service account for the Waldur Site Agent:
```bash
# Create service account in the desired namespace
oc create serviceaccount waldur-site-agent -n waldur-system
# Alternative: Use the default namespace
oc create serviceaccount waldur-site-agent -n default
```
### 2. Grant Permissions
Create a ClusterRole with necessary permissions:
```yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
name: waldur-site-agent
rules:
# OpenShift project management
- apiGroups: ["project.openshift.io"]
resources: ["projects", "projectrequests"]
verbs: ["create", "delete", "get", "list", "patch", "update"]
# Kubernetes namespace and resource quota management
- apiGroups: [""]
resources: ["namespaces", "resourcequotas"]
verbs: ["create", "delete", "get", "list", "patch", "update"]
# User access management through role bindings
- apiGroups: ["rbac.authorization.k8s.io"]
resources: ["rolebindings"]
verbs: ["create", "delete", "get", "list", "patch", "update"]
# Resource monitoring and usage reporting
- apiGroups: [""]
resources: ["pods", "services", "persistentvolumeclaims"]
verbs: ["get", "list"]
# API discovery for cluster connectivity checks
- apiGroups: [""]
resources: [""]
verbs: ["get"]
```
Bind the role to the service account:
```bash
# Bind the cluster role to the service account
oc adm policy add-cluster-role-to-user waldur-site-agent -z waldur-site-agent -n waldur-system
# Alternative: Using oc create command
oc create clusterrolebinding waldur-site-agent \
--clusterrole=waldur-site-agent \
--serviceaccount=waldur-system:waldur-site-agent
```
### 3. Get Service Account Token
#### For Production Deployment (Recommended)
Create a long-lived token for production use:
```bash
# OpenShift 4.11+ (recommended for production)
oc create token waldur-site-agent \
--namespace=waldur-system \
--duration=8760h \
--bound-object-kind=Secret \
--bound-object-name=waldur-site-agent-token
# Create a secret-bound token for enhanced security
oc apply -f - < **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 (GB) | Small: 1, Medium: 2, Large: 8 |
| `vm_disk` | Disk (GB) | Small: 5, Medium: 10, Large: 50 |
Memory and disk are expressed in the component's `measured_unit` (e.g. GB)
and converted to the backend's native MB via `unit_factor` (1024). The
agent multiplies each plan amount by `unit_factor` before sizing the VM.
### Inference (vLLM) Offerings
An inference offering is a VM offering (`resource_type: vm`) whose template is a
vLLM engine appliance. When the order carries a `model`, the backend
instantiates the engine template **with the model image attached as an extra
disk** and injects the `ONEAPP_VLLM_*` serving parameters into the VM context.
The served OpenAI-compatible endpoint is reported back to Waldur as resource
**access endpoints** (shown in the *Access resource* dropdown) and
`backend_metadata`.
A ready-to-import sample offering is provided in
[`examples/vllm-inference-offering.yaml`](examples/vllm-inference-offering.yaml)
— import it via the marketplace `import_offering` endpoint (the file documents
the call) and adjust the IDs to your deployment.
Agent config is the same as any VM offering:
```yaml
offerings:
- name: "vLLM Inference (OpenNebula)"
backend_type: "opennebula"
backend_settings:
api_url: "http://opennebula-host:2633/RPC2"
credentials: "oneadmin:password"
resource_type: "vm"
backend_components: {}
```
Everything inference-specific is configured on the **Waldur offering**:
| Where | Key | Purpose |
|---|---|---|
| `plugin_options` | `template_id` | The vLLM engine VM template ID (may be `0`). |
| `plugin_options` | `engine_image_id` | Engine disk image ID. Optional; falls back to the template's own disk(s). |
| `plugin_options` | `parent_vdc_backend_id` | Parent VDC for the VM (its `_internal` net + `_default` SG must exist). |
| order attributes | `model` | Model image **name** (agent resolves to an ID) or numeric ID; expose as an enum. |
| order attributes | `ONEAPP_VLLM_API_PORT` | API port (default `8000`). |
| order attributes | `ONEAPP_VLLM_API_WEB` | Deploy the chat web UI (`YES`/`NO`). |
| order attributes | `ONEAPP_VLLM_MODEL_QUANTIZATION` | `0` or `4`. |
| order attributes | `ONEAPP_VLLM_MODEL_MAX_LENGTH` | Context length. |
| order attributes | `ONEAPP_VLLM_ENFORCE_EAGER` | `YES`/`NO`. |
| order attributes | `ONEAPP_VLLM_SLEEP_MODE` | `YES`/`NO`. |
| order attributes | `ONEAPP_VLLM_GPU_MEMORY_UTILIZATION` | Fraction in `(0, 1]`. |
VM size (vCPU / RAM / disk) comes from the plan's FIXED components, as for any
VM offering. Switching plan triggers a **VM resize**: the agent powers the VM
off, applies the new vCPU/RAM and grows the disk, then powers it back on — so a
plan switch causes brief downtime, and the disk can only grow, not shrink.
**Models must be pre-registered as images** in the OpenNebula datastore (e.g.
exported from an `hfhub` marketplace). The backend validates the model image is
in a usable state (`READY`/`USED`) before instantiation and fails the order
cleanly otherwise.
**In-browser playground.** Set `plugin_options.expose_inference_playground:
true` to show a **Playground** action in HomePort that chats with the model
directly from the browser. It calls the endpoint client-side, so the endpoint
must be reachable from the user's browser.
**Surfacing the endpoint to users.** The agent reports two access endpoints —
`vLLM API (OpenAI-compatible)` (`/v1`) and `Chat playground`
(``) — rendered by HomePort's *Access resource* dropdown. To also show
a copy-paste snippet, set the offering's **Getting started** text; the
following substitution variables are available: `{resource_name}`,
`{backend_metadata_endpoint}`, `{backend_metadata_web_ui}`,
`{backend_metadata_model}`. Example:
````text
Your inference service **{resource_name}** serves model image
{backend_metadata_model} over an OpenAI-compatible API.
**API base URL:** {backend_metadata_endpoint}/v1
```bash
curl {backend_metadata_endpoint}/v1/models
```
**Chat playground:** {backend_metadata_web_ui}
````
> The Getting started text is rendered with single-brace `{var}` substitution,
> so avoid literal `{` / `}` (e.g. JSON request bodies) — they are treated as
> unknown variables.
>
> **No API key.** The stock vLLM engine appliance serves an **unauthenticated**
> API; access is gated only by reachability of the VDC network. Do not expose
> the endpoint on a public/floating IP without adding authentication.
### Backend Settings Reference
| Key | Required | Default | Description |
|---|---|---|---|
| `api_url` | Yes | - | OpenNebula XML-RPC endpoint |
| `credentials` | Yes | - | `username:password` authentication string |
| `zone_id` | No | `0` | OpenNebula zone ID |
| `cluster_ids` | No | `[]` | List of cluster IDs for VDC/VM placement |
| `resource_type` | No | `vdc` | `vdc` or `vm` -- determines offering mode |
| `create_opennebula_user` | No | `false` | Create an OpenNebula user per VDC |

| `template_id` | No | - | VM template ID (VM mode only) |
| `sched_requirements` | No | - | OpenNebula scheduling expression |
Settings can also be provided via the Waldur offering's `plugin_options`,
which take precedence over `backend_settings` for `parent_vdc_backend_id`,
`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. Expose memory and disk
in GB and set `unit_factor: 1024` so the agent scales the plan amount
to the backend's native MB.
```yaml
components:
vcpu:
measured_unit: "cores"
accounting_type: "fixed"
vm_ram:
measured_unit: "GB"
unit_factor: 1024
accounting_type: "fixed"
vm_disk:
measured_unit: "GB"
unit_factor: 1024
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. |

end
```
### Rollback on Failure
If any networking step fails, previously created networking resources are
cleaned up in reverse order before the error is propagated. The VDC and
group are then also rolled back by the base framework.
### User Account Creation
When `create_opennebula_user: true` is set in `backend_settings`, VDC
creation also provisions an OpenNebula user account with username
`{vdc_name}_admin` and a random password.
The user gets OpenNebula permissions automatically through VDC group
membership -- no explicit ACLs are needed.
#### Credential Display
Credentials (`opennebula_username`, `opennebula_password`) are pushed to
Waldur immediately after creation via `backend_metadata`. They appear in
Homeport on the resource detail page.
#### Password Persistence
The password is stored in the OpenNebula user's TEMPLATE as
`WALDUR_PASSWORD`. On agent restart, `get_resource_metadata()` re-reads
credentials from the ONE user TEMPLATE, so they survive across agent
restarts without any external state.
#### Deletion
When the VDC is terminated, the associated OpenNebula user is deleted
before the VDC and group are removed.
#### Password Reset
The backend exposes `reset_vdc_user_password(resource_backend_id)` which
generates a new password and updates both OpenNebula auth and TEMPLATE.
This is currently a backend-only method; the Mastermind/Homeport trigger
mechanism will be added in a future release.

end
```
### Resize Notes
- Disk **shrink is not supported** -- only grow. If the new plan has a
smaller disk, the disk resize step is skipped.
- The resize uses `enforce=False` to skip OpenNebula group quota checks
since Waldur is the authority for resource allocation.
- If the resize fails after poweroff, the VM is **automatically resumed**
to avoid leaving it in a powered-off state.
### VM Usage Reporting
VM usage reports the current allocation (not actual utilization):
| Component | Source | Description |
|---|---|---|
| `vcpu` | `TEMPLATE/VCPU` | Virtual CPUs assigned |
| `vm_ram` | `TEMPLATE/MEMORY` | Memory assigned (MB) |
| `vm_disk` | `TEMPLATE/DISK/SIZE` | Total disk size (MB) |
This is appropriate for FIXED billing -- charge based on what's
provisioned, not what's consumed.
## Quota Management
### Component Mapping (VDC Mode)
Waldur component keys map to OpenNebula quota sections:
| Waldur Component | OpenNebula Quota | Section |
|---|---|---|
| `cpu` | `VM/CPU` | VM |
| `ram` | `VM/MEMORY` | VM |
| `storage` | `DATASTORE/SIZE` | Datastore |
| `floating_ip` | `NETWORK/LEASES` | Network |
### Unit Conversion
Values are converted between Waldur and OpenNebula units using
`unit_factor`:
- **Waldur to OpenNebula**: `waldur_value * unit_factor = backend_value`
- **OpenNebula to Waldur**: `backend_value / unit_factor = waldur_value`
With `unit_factor: 1` (default), values pass through unchanged.
### Usage Reporting (VDC)
VDC usage reports reflect **current** resource consumption (VMs running
now), not accumulated historical usage. The backend sets
`supports_decreasing_usage = True` to indicate that usage values can
decrease when VMs are stopped or deleted.
## Architecture
### Component Overview
```text
plugins/opennebula/
+-- waldur_site_agent_opennebula/
| +-- backend.py # OpenNebulaBackend (BaseBackend subclass)
| +-- client.py # OpenNebulaClient (BaseClient subclass)

| +-- test_backend.py # 233 unit tests
| +-- test_integration.py # 20 integration tests (real OpenNebula)
+-- pyproject.toml # Package config + entry point
```
### Backend (backend.py)
`OpenNebulaBackend` extends `BaseBackend` and implements:
- `ping()` / `diagnostics()` -- connectivity checks
- `list_components()` -- configured component types
- `_pre_create_resource()` -- VDC: network config; VM: plan quotas +
template resolution
- `_create_backend_resource()` -- VDC: creates group/VDC/networking;
VM: instantiates from template
- `post_create_resource()` -- creates OpenNebula user, pushes credentials
- `_pre_delete_resource()` -- deletes OpenNebula user before VDC removal
- `set_resource_limits()` -- VDC: group quotas; VM: resize
(poweroff/resize/resume)
- `_collect_resource_limits()` -- converts Waldur limits with unit_factor
- `_get_usage_report()` -- VDC: group quota usage; VM: current allocation
- `get_resource_metadata()` -- VNet/VR metadata and user credentials
- `reset_vdc_user_password()` -- resets user password (action scaffold)
- `downscale_resource()` / `pause_resource()` / `restore_resource()` --
no-ops
### Client (client.py)
`OpenNebulaClient` wraps pyone and implements:
- **VDC/Group CRUD**: create, delete, list, get (idempotent creates)
- **Quota management**: build/parse quota templates, set/get limits
and usage
- **VM operations**: create, terminate, resize, get usage, wait for state
- **Network helpers**: VXLAN VNet, Virtual Router, Security Group CRUD
- **Subnet allocation**: stateless next-available from configured pool
- **User management**: create, delete, get credentials, reset password
- **Orchestration**: `_setup_networking()` / `_teardown_networking()`
- **Naming convention**: `{backend_id}_internal`,
`{backend_id}_router`, `{backend_id}_default`
## Usage
### Running the Agent
```bash
# Resource provisioning (create/delete VDCs and VMs)
uv run waldur_site_agent -m order_process -c config.yaml
# Usage reporting (quota counters / VM allocation to Waldur)
uv run waldur_site_agent -m report -c config.yaml
```
## Testing
### Running Unit Tests

# Specific test class
uv run pytest plugins/opennebula/tests/test_backend.py::TestVDCCreateWithNetworking -v
```
### Running Integration Tests
Integration tests run against a real OpenNebula instance and are gated
by environment variables:
```bash
OPENNEBULA_INTEGRATION_TESTS=true \
OPENNEBULA_API_URL="http://opennebula-host:2633/RPC2" \
OPENNEBULA_CREDENTIALS="oneadmin:password" \
OPENNEBULA_CLUSTER_IDS="0,100" \
OPENNEBULA_VM_TEMPLATE_ID="0" \
uv run pytest plugins/opennebula/tests/test_integration.py -v
```
| Variable | Required | Description |
|---|---|---|
| `OPENNEBULA_INTEGRATION_TESTS` | Yes | Set to `true` to enable |
| `OPENNEBULA_API_URL` | Yes | XML-RPC endpoint |
| `OPENNEBULA_CREDENTIALS` | Yes | Admin credentials (`user:pass`) |
| `OPENNEBULA_CLUSTER_IDS` | No | Comma-separated cluster IDs |
| `OPENNEBULA_VM_TEMPLATE_ID` | No | VM template ID for instantiation |
The integration tests exercise the full VDC lifecycle: create VDC, set
quotas, create user, authenticate as user, instantiate VM, verify usage,
reset password, and clean up.

## Troubleshooting
### Connection Reset Errors
OpenNebula XML-RPC servers may reset TCP connections under load.
The client handles this via idempotent create operations: if a resource
is created but the response is lost, subsequent retries detect the
existing resource and reuse it.
For production deployments, consider configuring HTTP-level retry on
the transport layer (e.g. via a requests Session with urllib3 Retry).
### VR Instantiation Fails
```text
Cannot get IP/MAC lease from virtual network
```
This means the Virtual Router cannot obtain an IP from the specified
network. Check that:
- The external network has available IP leases in its address range
- The internal VXLAN network's AR includes the gateway IP
- The VNF appliance template ID is correct and the image is available
### Networking Not Created
If VDCs are created without networking when you expect it, verify that
the Waldur offering `plugin_options` contains both `external_network_id`
and `virtual_router_template_id`. Both are required to trigger networking
provisioning.
### Quota Mismatch
If reported limits don't match expected values, check the `unit_factor`
in the offering component configuration. The default is `1` (no
conversion). Values flow as:
`waldur_value * unit_factor = opennebula_quota_value`.
### VM Resize Fails
If a plan switch order fails during resize, check:
- The VM must be in ACTIVE or POWEROFF state
- Disk shrink is not supported (only grow)
- The agent logs will show the specific OpenNebula error
If resize fails after poweroff, the VM is automatically resumed.

### OpenNebula Keycloak SAML Integration Setup Guide
# OpenNebula Keycloak SAML Integration Setup Guide
This guide covers setting up the OpenNebula site-agent plugin with Keycloak SAML
integration for VDC user management. When enabled, the plugin automatically creates
Keycloak groups and OpenNebula SAML-mapped groups for each VDC, allowing users to
log in to Sunstone via SSO.

```
## Prerequisites
1. **OpenNebula 6.8+** with FireEdge and SAML auth driver enabled
2. **Keycloak** (any recent version) accessible from both the site-agent and the OpenNebula frontend
3. **waldur-site-agent** with the `opennebula` and `keycloak-client` plugins installed
## Step 1: Configure Keycloak
### 1.1 Create a Realm
Create a Keycloak realm for OpenNebula (e.g., `opennebula`). This realm will hold all users and VDC groups.
### 1.2 Create a SAML Client
In the realm, create a SAML client:
| Setting | Value |
|---------|-------|
| Client ID | `opennebula-sp` |
| Client Protocol | `saml` |
| Valid Redirect URIs | `https:///fireedge/api/auth/acs` |
| Name ID Format | `username` |
### 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

INFO: Marking order as done
INFO: The order has been successfully processed
```
The resource appears in the project:
[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
```
1. The plugin will be automatically discovered via Python entry points.

## 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
- **GPU**: Measured in units (optional, see [GPU Scheduling](#gpu-scheduling))
### 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
## GPU Scheduling
The plugin supports GPU quota management via Kubernetes ResourceQuotas combined with
namespace-label-based scheduling. This approach uses a single generic `nvidia.com/gpu`
resource for quotas, and a **Kyverno policy** on the cluster to steer GPU workloads
to the correct node pool based on a namespace label.
### How It Works
1. **Site agent** creates a namespace with a `gpu-pool` label (configured via `namespace_labels`)
2. **Site agent** applies a ResourceQuota with `requests.nvidia.com/gpu: N` (generic GPU count)
3. **Kyverno policy** on the cluster reads the namespace's `gpu-pool` label and injects
a matching `nodeSelector` into every pod, ensuring GPU workloads land on the correct nodes
4. **GPU nodes** are labeled with `gpu-pool=` (e.g., `gpu-pool=h100-2x`)
### Offering Setup
Create a **separate Waldur offering per GPU pool type**. Each offering's backend config
specifies the GPU pool label:
```yaml
offerings:
# Offering for H100 GPU pool
- name: "k8s-gpu-h100"
uuid: "..."
backend_type: "rancher"
backend:
backend_url: "https://rancher.example.com"
username: "..."
password: "..."
cluster_id: "c-m-1234abcd"
namespace_labels:
gpu-pool: "h100-2x"
components:
cpu:
type: "cpu"
name: "CPU"
measured_unit: "cores"
memory:
type: "ram"
name: "RAM"
measured_unit: "GB"
gpu:
type: "gpu"
name: "GPU"
measured_unit: "units"
# Offering for H200 GPU pool
- name: "k8s-gpu-h200"
uuid: "..."
backend_type: "rancher"
backend:
backend_url: "https://rancher.example.com"
username: "..."
password: "..."
cluster_id: "c-m-1234abcd"
namespace_labels:
gpu-pool: "h200-8x"
components:
cpu:
type: "cpu"
name: "CPU"
measured_unit: "cores"
memory:
type: "ram"
name: "RAM"
measured_unit: "GB"
gpu:
type: "gpu"
name: "GPU"
measured_unit: "units"
```
### Required Kubernetes Setup
#### 1. Label GPU Nodes
Each GPU node must be labeled with its pool type matching the `namespace_labels` values:
```bash
kubectl label node gpu-h100-node-01 gpu-pool=h100-2x
kubectl label node gpu-h100-node-02 gpu-pool=h100-2x
kubectl label node gpu-h200-node-01 gpu-pool=h200-8x
```
#### 2. Deploy Kyverno Policy
A Kyverno `ClusterPolicy` must be deployed on the cluster to inject `nodeSelector`
into pods based on the namespace's `gpu-pool` label. This is the minimal policy:
```yaml
apiVersion: kyverno.io/v1
kind: ClusterPolicy
metadata:
name: enforce-gpu-pool-node-selector
spec:
rules:
- name: set-node-selector-from-namespace-label
match:
any:
- resources:
kinds:
- Pod
context:
- name: gpupool
apiCall:
urlPath: /api/v1/namespaces/{{ request.namespace }}
jmesPath: metadata.labels."gpu-pool" || ''
method: GET
preconditions:
all:
- key: "{{ gpupool }}"
operator: NotEquals
value: ""
mutate:
patchStrategicMerge:
spec:
nodeSelector:
gpu-pool: "{{ gpupool }}"
```
This policy:
- Matches **all Pods** in every namespace
- Fetches the namespace's `gpu-pool` label via Kubernetes API
- **Precondition**: only fires if the label is non-empty (CPU-only namespaces are unaffected)
- **Mutates**: injects `nodeSelector: {gpu-pool: ""}` into the Pod spec
- Kyverno **auto-generates** equivalent rules for Deployments, StatefulSets, Jobs, CronJobs, etc.
#### 3. Optional: Default No-GPU Quota Policy
To prevent accidental GPU usage in namespaces without a GPU pool label,
deploy a generate policy that creates a zero-GPU ResourceQuota:
```yaml
apiVersion: kyverno.io/v1
kind: ClusterPolicy
metadata:
name: default-no-gpu-quota
spec:
rules:
- name: generate-no-gpu-quota
match:
any:
- resources:
kinds:
- Namespace
selector:
matchExpressions:
- key: gpu-pool
operator: DoesNotExist
exclude:
any:
- resources:
namespaces:
- kube-system
- kube-public
- kube-node-lease
- kyverno
generate:
apiVersion: v1
kind: ResourceQuota
name: no-gpu-quota
namespace: "{{request.object.metadata.name}}"
synchronize: true
data:
spec:
hard:
requests.nvidia.com/gpu: "0"
limits.nvidia.com/gpu: "0"
```
## 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
uvx prek 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"
```

### waldur-site-agent-rancher-kc-crd
# waldur-site-agent-rancher-kc-crd
CRD-driven Rancher + Keycloak membership-sync plugin for Waldur Site
Agent. Translates Waldur `Resource` + `ResourceProject` + `UserRole`
state into `ManagedRancherProject` Custom Resources; the
`rancher-keycloak-operator` running inside the target Kubernetes
cluster owns the actual Rancher project + Keycloak group lifecycle.
## Expected operator
This plugin only writes CRs — it relies on
[`waldur/rancher-keycloak-operator`][operator-github] to be running
in the target Kubernetes cluster. That operator owns the
`ManagedRancherProject` and `RancherProjectInventory` CRD definitions
and is the only thing that talks to Rancher and Keycloak APIs.
Minimum operator version compatible with the current plugin: **`0.3.0`**.
**Recommended: `0.3.1`+** — earlier 0.3.x bug-fixes a metadata-sync gap
where description / organization / projectSlug changes never reached
Rancher after the initial create. The plugin no longer emits
`spec.namespace`, which `0.2.x` operators relied on for namespace
creation; earlier versions also miss audit fields and the
stale-project-ID cleanup fallback that the plugin assumes.
The operator's helm chart lives in its own repo under
`helm/rancher-keycloak-operator/`; install instructions are in the
[Setup](#setup) section below.
[operator-github]: https://github.com/waldur/rancher-keycloak-operator
## Scope
**`membership_sync_backend` only.** This plugin handles user-to-project
role bindings. It does not provision or terminate Rancher clusters,
does not process orders, and does not report usage. Order processing
and reporting are out of scope; if the offering needs them they have
to be wired through other backends.
**Cluster pre-exists.** Each Waldur Resource's `backend_id` is its
Rancher cluster ID; this plugin does not stand up Rancher clusters.
**Opt-in per offering.** Set
`membership_sync_backend: rancher-kc-crd` on the offering's
site-agent config to route its membership sync through this plugin.
**Membership is per-ResourceProject, not a flat per-Resource team.**
Unlike SLURM-style backends, there's no single "team" for the whole
Resource — each ResourceProject has its own `UserRole` list, and
that's what drives Keycloak group membership (see
[User identity matching](#user-identity-matching) for exactly which
field). The site agent's generic team-vs-backend membership diff
(used by flat-team backends to detect new/stale users) doesn't apply
here and is skipped for this backend — see `skip_resource_team_diff`
in `waldur_site_agent_rancher_kc_crd/backend.py`.

```
The plugin's responsibilities stop at writing CRs and reading their
status. The operator owns:
- creating / adopting Rancher projects, namespaces, and resource quotas
- creating Keycloak parent + child groups and binding them to the
Rancher project via `ProjectRoleTemplateBinding` (PRTB) with
`groupPrincipalId: keycloakoidc_group://`
- adding/removing users to/from Keycloak groups based on
`spec.keycloak.roleBindings[].members[]`
- cascading cleanup on CR delete (`@kopf.on.delete`)
---
## Sequence: end-to-end membership sync
This is what happens on a single `pull_resource` call (i.e. one
membership-sync cycle per Resource the offering owns).
```mermaid

K-->>PG: [all CRs for this resource]
PG->>K: kube delete (CRs whose RP no longer in Waldur)
K-->>OP: watch event (delete)
OP->>R: delete PRTBs + project (with stale-ID find-by-name fallback)
OP->>KC: delete child groups, parent group if empty
PG-->>SA: BackendResourceInfo(users=union of synced members)
```
**Key invariants:**
- **Idempotent at every step.** Re-applying the same CR yields the
same Rancher project and Keycloak groups. Re-syncing with the same
user set is a no-op on the Rancher/Keycloak side.
- **One CR per ResourceProject**, named
`-`. Stable across renames.
- **Orphan pruning by label.** CRs are stamped with
`metadata.labels.waldur.io/resource-uuid`; on each sync the plugin
computes the set of expected CR names from the *current* Waldur RP
list, then deletes any label-matching CR outside that set.
- **Lookup-only for users.** The operator never creates Keycloak
users; it only binds existing ones. Users absent from Keycloak get
a `WARNING User not found in Keycloak` and are skipped (the
PRTB and the group are still created — they're just empty for that
user).
---
## Sequence: orphan-CR pruning
```mermaid
sequenceDiagram

OP->>R: delete Rancher project
alt stored project ID is stale (e.g. project recreated externally with new ID)
OP->>R: DELETE /v3/projects/ -> 404

R-->>OP: {id: }
OP->>R: DELETE /v3/projects/ -> 200
end
OP->>K: remove finalizer (CR fully gone)
```
**Why pruning lives in the plugin, not the operator:** the operator
doesn't know about Waldur — the Waldur RP list is the source of
truth, and only the plugin sees both sides. The label selector keeps
pruning safe: CRs without the label (manually-created, or from a
different source) are never touched.
---
## Sequence: cleanup on stale `rancherProjectId`
When a Rancher project is externally deleted and recreated between
two operator reconciles, the CR's `status.rancherProjectId` points
at a non-existent ID. The cleanup falls back to finding the live
project by `clusterId+projectName`:
```mermaid
sequenceDiagram
autonumber
participant U as User / Test
participant K as Kubernetes
participant OP as Operator
participant R as Rancher
Note over U: status.rancherProjectId = p-OLD
(actual Rancher project: p-NEW, same name)
U->>K: kubectl delete mrp
K-->>OP: on_delete handler fires
OP->>R: DELETE /v3/projects/p-OLD
R-->>OP: 404 Not Found
Note over OP: delete_project returned False
-> stored ID is stale
OP->>R: GET /v3/projects?clusterId=…&name=
R-->>OP: [{id: p-NEW, …}]
OP->>OP: log WARNING — stored projectId p-OLD was stale, deleting current p-NEW found by name
OP->>R: DELETE /v3/projects/p-NEW
R-->>OP: 200 OK
OP->>K: cleanup complete — release finalizer
```
This was the failure mode that left orphan Rancher projects after
external recreation; fix landed in operator `0.2.2`.
---
## Setup
### 1. Operator: install in target cluster
The [`waldur/rancher-keycloak-operator`][operator-github] must be
running in the cluster you point this plugin at. One operator
instance handles **all** `ManagedRancherProject` CRs in its
namespace; one operator can manage Rancher projects across multiple
downstream Rancher clusters (each CR specifies its own `clusterId`).
#### 1a. CRDs
```bash
# Clone the operator repo (separate from waldur-site-agent):
git clone https://github.com/waldur/rancher-keycloak-operator.git
cd rancher-keycloak-operator
kubectl apply -f helm/rancher-keycloak-operator/templates/crds/
kubectl get crds | grep waldur.io
# expect:
# managedrancherprojects.waldur.io
# rancherprojectinventories.waldur.io
```
#### 1b. Helm install (published image)
The published image is `opennode/rancher-keycloak-operator:`
on Docker Hub. Pin a specific version (don't use `:latest`):
```bash
kubectl create namespace waldur-system
helm upgrade --install rko \
./helm/rancher-keycloak-operator \
--namespace waldur-system \
--set image.repository=opennode/rancher-keycloak-operator \
--set image.tag=0.3.1 \
--set image.pullPolicy=IfNotPresent \
--set "config.rancher.url=https://rancher.example.com" \
--set "config.rancher.bearerToken=" \
--set "config.rancher.verifySsl=true" \
--set "config.keycloak.url=https://keycloak.example.com" \
--set "config.keycloak.realm=" \
--set "config.keycloak.userRealm=master" \
--set "config.keycloak.username=" \
--set "config.keycloak.password=" \
--set "config.keycloak.verifySsl=true"
kubectl rollout status deploy/rko-rancher-keycloak-operator -n waldur-system
```
#### 1c. Smoke-test the operator (optional but recommended)
The [operator repo][operator-github] ships a Tier-1 runbook at
`docs/tier-1-runbook.md` that walks through applying a hand-crafted
CR end-to-end against the configured Rancher and Keycloak before
wiring in the site-agent. Run it once per cluster to catch
credential / connectivity issues early.
#### 1d. Required Rancher + Keycloak permissions
| System | Role / scope |
|---|---|
| Rancher token | unscoped admin OR cluster-owner across all clusters this operator instance will manage |
| Keycloak admin user | realm-admin on the target realm (group create/delete, group member add/remove, user lookup) |
---
### 2. Plugin: install on the site-agent host
The plugin is a workspace member of the
`waldur-site-agent` repo and is installed automatically when you run
`uv sync --all-packages` at the repo root. To verify it's discovered:
```bash
uv run python -c "from waldur_site_agent_rancher_kc_crd import backend; print(backend.RancherKcCrdBackend)"
```
#### 2a. Site-agent host needs
- Network access to: Waldur Mastermind API, the Kubernetes API of the
cluster running the operator.
- A kubeconfig file (or in-cluster service-account credentials if
you run the agent inside the operator's cluster).
- The Kubernetes API user must be allowed to
`get/list/create/update/delete/patch` `managedrancherprojects.waldur.io`
in the chosen namespace.
#### 2b. Configure the offering
Add a stanza to `waldur-site-agent-config.yaml`. Full reference at
[examples/rancher-kc-crd-config.yaml](examples/rancher-kc-crd-config.yaml).
```yaml
offerings:
- name: "my-rancher-offering"
waldur_api_url: "https://waldur.example.com/api/"
waldur_api_token: "${WALDUR_API_TOKEN}"
waldur_offering_uuid: ""
backend_type: "rancher-kc-crd"
membership_sync_backend: "rancher-kc-crd"

# Repeats the top-level waldur_api_url/waldur_api_token on purpose.
# This plugin fetches ResourceProjects and UserRoles directly from
# Waldur inside pull_resource, but backends aren't handed the
# framework's own Waldur client -- that's deliberately scoped to
# the processor, not backends in general. So the plugin builds its
# own AuthenticatedClient from these settings instead. Most other
# backends don't need this because they don't talk to the Waldur
# API themselves.

#### 2c. Run
`rancher-kc-crd` is a `membership_sync_backend` only. Order
processing and reporting still need other backends (or none).
```bash
uv run waldur_site_agent --mode membership_sync \
--config-file waldur-site-agent-config.yaml
```
Observability:
```bash
# Watch CRs being created/updated/deleted
kubectl get mrp -n waldur-system -L waldur.io/resource-uuid -w
# Inspect any CR's reconciliation state
kubectl describe mrp -n waldur-system
# Operator logs (cleanup, member sync, drift)
kubectl logs deploy/rko-rancher-keycloak-operator -n waldur-system --tail=100 -f
```

## User identity matching
The plugin can match Waldur users to Keycloak users either by username
(default) or by UUID. Choose with `backend_settings.keycloak_use_user_id`:
**`false` (default) — match by username**
: Plugin sends `UserRole.user_username`. Operator does
`GET /admin/realms//users?username=X&exact=true` and uses
the resulting `user.id` for group membership operations. Works in
both OIDC and self-hosted Waldur as long as Waldur usernames
align with Keycloak usernames — the typical OIDC mapping does this
via the `preferred_username` claim.
**`true` — match by UUID**
: Plugin sends `UserRole.user_uuid`. Operator does
`GET /admin/realms//users/{uuid}` (matches the Keycloak
internal `user.id`). Use this only when Waldur was OIDC-provisioned
AND its user UUIDs were seeded from the Keycloak `sub` claim, so
that `Waldur.user.uuid == Keycloak.user.id`. The username path is
preferred because it tolerates UUID divergence and works in more
topologies.
**This is not `OfferingUser.username`.** SLURM-style backends key
membership off `OfferingUser.username` — a per-offering, often
auto-generated identifier (e.g. a POSIX account name like
`test-rancher-00`) meant for the *target system*, not Keycloak. This
plugin never looks at that field. Its membership unit is each
ResourceProject's `UserRole`, and the identity it hands to the
operator is `UserRole.user_username` (or `user_uuid`) — the person's
actual Waldur account identity. If a user was added to Keycloak under
a name that doesn't match their real Waldur username, the operator
logs `WARNING User not found in Keycloak` and silently skips
them (see Troubleshooting) even though everything else — CR, group,
PRTB — looks fully synced.
**The operator never creates users.** A user that doesn't exist in
Keycloak under the chosen identifier gets logged as
`WARNING User not found in Keycloak` and is skipped — the
PRTB and the group are still created and bound, the user just isn't
a member yet. They become a member on the next reconcile after the
user appears in Keycloak (e.g. their first OIDC login).

## Configuration reference
`waldur_api_url`/`waldur_api_token` below intentionally repeat the
offering's top-level fields of the same name — see the setup example
above for why.
| Key | Type | Required | Description |
|---|---|---|---|
| `waldur_api_url` | string | yes | Mastermind API root with `/api/`. Plugin strips trailing `/api` for the SDK. |
| `waldur_api_token` | string | yes | Long-lived token from `/api/users/
