Fix CI/CD Pipeline Flow

The Fix CI/CD Pipeline Flow helps you automatically diagnose and fix issues in your GitLab CI/CD pipeline. This flow:

• Analyzes pipeline failure logs and error messages.
• Identifies configuration issues and syntax errors.
• Suggests specific fixes based on the type of failure.
• Creates a merge request with changes that attempt to fix a failing pipeline.

The flow can automatically fix various pipeline issues, including:

• Syntax and configuration errors.
• Common job failures.
• Dependency and workflow issues.

This flow is available in the GitLab UI only.

Prerequisites

To use this flow, you must:

• Have an existing failed pipeline.
• Have at least the Developer role in the project.
• Meet the other prerequisites.
• Ensure the GitLab Duo service account can create commits and branches.

Fix the pipeline in a merge request

To fix the CI/CD pipeline in a merge request:

1. On the top bar, select Search or go to and find your project.

2. Select Code > Merge requests and open your merge request.

3. To fix the pipeline, you can either:

   • Select the Overview tab and under the failing pipeline, select Fix pipeline with Duo.
   • Select the Pipelines tab and in the rightmost column, select Fix pipeline with Duo ( ).

4. To monitor progress, select Automate > Sessions.

When the session is complete, a comment shows a link to a merge request that contains the fix, or a comment describes possible next steps.

Fix other CI/CD pipelines

To fix a CI/CD pipeline that is not associated with a merge request:

1. Select Build > Pipelines.
2. Select your failing pipeline.
3. In the upper-right corner, select Fix pipeline with Duo.
4. To monitor progress, select Automate > Sessions.

What the flow analyzes

The Fix CI/CD Pipeline Flow examines:

• Pipeline logs: Error messages, failed job outputs, and exit codes.
• Merge request changes: Changes that could have caused the failure.
• The current repository contents: For identifying syntax, linting, or import errors.
• Script errors: Command failures, missing executables, or permission issues.
