Understanding GitLab Custom CI Configuration Path for Merge Requests

When working with GitLab, managing Continuous Integration (CI) configurations can be challenging, especially when using a Custom CI configuration path. This scenario often arises when teams want to protect their CI configuration file (gitlab-ci.yml) from being modified by developers, particularly in environments that lack certain premium features.

In this post, we will explore a specific issue you may encounter when using Custom CI configuration paths in GitLab, focusing on the challenges related to merge requests. We'll also provide a detailed solution to ensure your CI processes work smoothly without creating unnecessary roadblocks for your development team.

The Problem

You might have set the Custom CI configuration path in your GitLab repository to point to a remote gitlab-ci.yml file. In our case, this configuration was established for the group1/repo1 repository, pointing to a CI setup in group1/repo1-ci.

Here’s a summary of the issue faced:

Setup: .gitlab-ci.yml@ group1/repo1-ci

Expected Behavior: The CI process should work seamlessly for any configured branches and when developers push their code directly.

Actual Behavior: For merge requests, the pipeline fails with the error message indicating that the project group1/repo1-ci was either not found or access was denied.

Developers were added to the repo1-ci repository with developer access, yet the problem persisted.

Identifying the Root Cause

It turns out there are essential considerations to keep in mind when dealing with Custom CI configuration paths during merge requests:

Permissions Matter:

Each user interacting with Merge Request features must have at least read access to the remote gitlab-ci.yml file.

This is crucial even if the file has been moved to another repository to leverage enhanced protection features.

Session Permissions:

Any permission changes must be reflected in the user's current session. If a developer adds permissions, these need to be applied immediately, but users might continue working from their previous session where those permissions weren't yet recognized.

Steps to Resolve the Issue

To tackle the merge request issue while utilizing a Custom CI configuration path, follow these steps:

Step 1: Verify User Permissions

Ensure that every user who will interact with the merge request has:

At least read permissions for the group1/repo1-ci repository.

Step 2: Confirm Session Validity

If you’ve recently updated user permissions:

Ask affected users to log out and log back in to their GitLab accounts. This action ensures their session is refreshed, and they acquire the updated permissions.

Step 3: Test the Configuration

After making the necessary adjustments, developers should:

Create a new merge request to check if the pipeline processes correctly.

Verify that the CI pipeline succeeds without encountering access-related errors.

Conclusion

Using a Custom CI configuration path in GitLab can significantly streamline your CI/CD workflow while adding layers of protection to your important files. However, it's vital to maintain clear communication around permissions and session management.

By ensuring that your team members have the correct access levels and that any permission changes are applied in an active session, you can eliminate headaches and interruptions to your development processes. If you continue to encounter issues, double-check the configurations and user permissions to assist any developers facing CI setbacks.



With the above steps, your GitLab setup can become more secure and efficient, enabling your team to collaborate without technical barriers. Happy coding!
