Consider the following pipeline, with jobs `A`, `B`, and `C`. If you want +all pipelines to always run `A` and `B`, but only want `C` to run for a merge request, +you can configure your `.gitlab-ci.yml` file as follows: + +``` yaml +.only-default: &only-default + only: + - master + - merge_requests + - tags + +A: + <<: *only-default + script: + - ... + +B: + <<: *only-default + script: + - ... + +C: + script: + - ... + only: + - merge_requests +``` + +Since `A` and `B` are getting the `only:` rule to execute in all cases, they will +always run. `C` specifies that it should only run for merge requests, so for any +pipeline except a merge request pipeline, it will not run. + +As you can see, this will help you avoid a lot of boilerplate where you'd need +to add that `only:` rule to all of your jobs in order to make them always run. You +can use this for scenarios like having only pipelines with merge requests get a +Review App set up, helping to save resources. + ## Important notes about merge requests from forked projects Note that the current behavior is subject to change.
