External pipeline validation (FREE SELF)

You can use an external service to validate a pipeline before it's created.

GitLab sends a POST request to the external service URL with the pipeline data as payload. The response code from the external service determines if GitLab should accept or reject the pipeline. If the response is:

• 200, the pipeline is accepted.
• 406, the pipeline is rejected.
• Other codes, the pipeline is accepted and logged.

If there's an error or the request times out, the pipeline is accepted.

Pipelines rejected by the external validation service aren't created, and don't appear in pipeline lists in the GitLab UI or API. If you create a pipeline in the UI that is rejected, Pipeline cannot be run. External validation failed is displayed.

Configure external pipeline validation

To configure external pipeline validation, add the EXTERNAL_VALIDATION_SERVICE_URL environment variable and set it to the external service URL.

By default, requests to the external service time out after five seconds. To override the default, set the EXTERNAL_VALIDATION_SERVICE_TIMEOUT environment variable to the required number of seconds.
