It's posible run a job from gitlab-ci only on merge request? Now, we have a big monolitic project with heavy tests, but we only want to run the test before merging to the branch master.

Well, it's not built in currently however it's not impossible to do it yourself. Gitlab allows to trigger a job. It also supports webhooks on merge requests. However webhooks don't support variable in URIs and triggers can't read request body so you'd have to create a script that will act like a middle-man here:

  1. Webhook on merge request calls to your script
  2. Script parses the request and calls a triggers in gitlab with correct REF

  3. Trigger runs the job that is marked with;

    only: -triggers

It's a bit hacky but it's working and easy to implement.
