Run gitlab pipeline only for commits

Currently gitlab runs a pipeline when creating a merge request + branch with the GUI.
Is it possible to skip this pipeline, since it's only repeats the last pipeline from the default branch?

We tried with:

workflow:
  rules:
    - if: $CI_MERGE_REQUEST_IID
    - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH

This works to skip new branch pipelines, but it doesn't run a pipeline for new commits on branches which have no merge request.

Solution

  • In order to stop pipeline execution when a new branch is created and in the same time run when a new commit happens on a branch

    Try change from:

    workflow:
  rules:
    - if: $CI_MERGE_REQUEST_IID
    - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH

    To

    workflow:
  rules:
    - if: $CI_COMMIT_BEFORE_SHA == "0000000000000000000000000000000000000000"
      when: never
    - if: $CI_MERGE_REQUEST_IID
    - if: $CI_PIPELINE_SOURCE == "push"

    The rule

    - if: $CI_COMMIT_BEFORE_SHA == "0000000000000000000000000000000000000000"
  when: never

    Will stop the execution of a new pipeline when a new branch is created

    The rule

    - if: $CI_PIPELINE_SOURCE == "push"

    This is added to allow a new pipeline trigger when a commit happens on branch, because if the event is not a merge request the pipeline won't execute.
