globalartltd/gitlab-mr-combiner repository overview

⁠Gitlab MR Combiner

Merge multiple merge requests into a single branch in GitLab using tags.

⁠How is it works?

1. Start the application
2. Configure a webhook to send a request when receiving a comment in a merge request (MR) in GitLab
   URL looks like: http://your-server.tld:8080/webhook⁠
3. The application receives the request
4. The application retrieves all MRs with a unique tag
5. Clone the repository
6. Merge all MRs into one branch
7. Push the changes into branch

⁠Installation

You can install this in docker:

docker run -d --rm --name gitlab-mr-combiner \
  -p 8080:8080 \
  -e TRIGGER_MESSAGE="/specific-message" \
  -e BRANCH="target_branch" \
  -e TRIGGER_TAG="specific_tag" \
  -e GITLAB_TOKEN="<your access_token>" \
  -e GITLAB_URL="<your_gitlab_url>, default is https://gitlab.com" \
  -v ~/.ssh:/root/.ssh:ro \
  globalartltd/gitlab-mr-combiner

You must store the SSH private key of any user who has access to the repository!
In this example, we mount it from the volume.

⁠Setup

1. Create a webhook for the group or repository, selecting the trigger: Comments.
2. In the project settings, create a specific tag from your Docker environment, for example: stage-mr.
3. Apply this tag to all merge requests (MRs) that you want to merge.
4. Send /specific-message from the Docker environment.
