Gitlab: Pipelines must succeed option with GOCD

[Janailtongp]

Hi everyone,

How to use: Settings > Merge checks > Pipelines must succeed option with GOCD?

Already received the pipeline result from gocd plugin for the commits, but the merge request checks not works. If "Pipelines must succeed" option is checked, the "Checking pipeline status" keeps in infinit loading.

I imagine it is due to the lack of the .gitlab-ci.yml file, but I don't know how to use it together with gocd.

Any idea how it would work?

It possibly only works with GitLab CI, not an external tool using the API. You probably need to check the GitLab documentation or ask their support whether it works with non GitLab CI tools?

https://docs.gitlab.com/ee/user/project/merge_requests/auto_merge.html#require-a-successful-pipeline-for-merge does say

You can configure your project to require a complete and successful pipeline before merge. This configuration works for both:

• GitLab CI/CD pipelines.
• Pipelines run from an external CI integration.

However GoCD does not have a dedicated integration so it's unclear to me whether that works just for something like this plugin, which only updates the pipeline status of a commit, but is maybe not known as a "pipeline" to Gitlab: https://docs.gitlab.com/ee/api/commits.html#set-the-pipeline-status-of-a-commit

It notes

This setting also prevents merge requests from merging if there is no pipeline_" which possibly means Gitlab itself needs to know there is a pipeline.

and

A merge request with no pipelines at all is not considered to have a successful pipeline, and cannot merge.

Can you share a (redacted) screenshot of what an MR and the commits on it look like for you when you think it should allow the 'Pipelines must succeed' check to continue?

It also probably depends on how you have configured GoCD to actually run the build off your merge requests. Are you using a manually created pipeling, or something like https://github.com/ashwanthkumar/gocd-build-github-pull-requests ?
