This n8n workflow streamlines the management of GitLab merge requests by automating checks, creations, updates, and comments. It is triggered on a schedule, making it ideal for continuous integration and development workflows.
The workflow begins with a scheduled trigger that initiates the process at regular intervals. It then checks for existing open merge requests on a specified branch using GitLab’s API. If an open request exists, the workflow can close and comment on the existing merge request.
If no existing open merge request is found, the workflow proceeds to create a new merge request with specified source and target branches, and a custom title. After creating the merge request, it waits for 30 seconds to allow manual approval or pipeline execution. Subsequently, it sets parameters to merge when the pipeline is successful and optionally removes the source branch.
Key nodes include HTTP Request nodes for interacting with GitLab, conditionals to check merge request existence, loops for handling multiple items, and wait nodes to pause for manual actions.
This automation facilitates continuous integration, simplifies merge request management, and ensures consistent handling of code updates, making it highly useful in development pipelines and collaborative environments.
