Gitlab job to run ONLY ONCE when Merge Request is created

Question

I want some specific jobs in my pipeline run only one time when I create a Merge Request. For example to assign reviewer for the MR, or to migrate data from QA environment.

Is there a way to achieve this in Gitlab?

Answer 1

Can you elaborate ? By default, all jobs are ran only one time. Are you talking about conditional runs ?

If so, I think the only/except concepts could be of interest. Maybe by using only:variables/except:variables. You would have to reimplement some logic in the background depending on your use case, though not so complicated (set a boolean at true/false).

See the doc for only/except
