Waldur SDK

Waldur SDK is a thin Python wrapper for common REST operations. It allows you to interact with the Waldur REST API directly from your Python code. The SDK is provided as a Python module named waldur_api_client.

Installation

The Waldur SDK is available on PyPI and can be installed using either pip or poetry:

1
2
pip install waldur-api-client
poetry add waldur-api-client

In order to perform operations, a user needs to create an instance of AuthenticatedClient class:

1

4
5
6
from waldur_api_client import AuthenticatedClient

client = AuthenticatedClient(
    base_url="https://api.example.com",
    token="SuperSecretToken",
)

This instance provides interface for further interaction with Waldur and will be used across examples in related documentation.

Error handling

If the API call fails or returns an unexpected status code, it may raise UnexpectedStatus exception if the client is configured with raise_on_unexpected_status=True. This can be handled using a try...except block. The exception contains both the status code and the response content for debugging purposes.

Example:

from waldur_api_client.api.marketplace_resources import marketplace_resources_list
from waldur_api_client.errors import UnexpectedStatus
import pprint

try:
    result = marketplace_resources_list.sync(client=client)
except UnexpectedStatus as e:
    print(f"Status code: {e.status_code}")
    print("Response content:")
    pprint.pprint(e.content)

The UnexpectedStatus exception is raised when:

  • The API returns a status code that is not documented in the OpenAPI specification
  • The raise_on_unexpected_status client setting is enabled (default is disabled)

If you are running your commands against Waldur deployment with broken TLS certificates (e.g. in development), the trick below can be used to disable validation of certificates by SDK, beware that this is a security risk.

client = AuthenticatedClient(
    base_url="https://internal_api.example.com", 
    token="SuperSecretToken",
    verify_ssl=False,
)

Sometimes you may need to authenticate to a server (especially an internal server) using a custom certificate bundle.

client = AuthenticatedClient(
    base_url="https://internal_api.example.com", 
    token="SuperSecretToken",
    verify_ssl="/path/to/certificate_bundle.pem",
)

Air gapped installation

If your machine from where you run SDK is not connected to the public Internet, you can use the following method to transfer required libraries.

On the machine with access to the Internet:

1
2
3
echo "https://github.com/waldur/py-client/archive/master.zip" > requirements.txt
mkdir dependencies
pip3 download -r requirements.txt -d dependencies/

Now transfer content of the dependencies folder and requirements.txt to a machine without public Internet and run.

1
pip3 install --no-index --find-links dependencies/  -r requirements.txt
