External Pipeline Validation

You can use an external service for validating a pipeline before it's created.

CAUTION: Warning: This is an experimental feature and subject to change without notice.

Usage

GitLab will send a POST request to the external service URL with the pipeline data as payload. GitLab will then invalidate the pipeline based on the response code. If there's an error or the request times out, the pipeline will not be invalidated.

Response Code Legend:

• 200 - Accepted
• 4xx - Not Accepted
• Other Codes - Accepted and Logged

Configuration

Set the EXTERNAL_VALIDATION_SERVICE_URL to the external service url.
