GitLab CD/CD: is there a way to allow to force execute pipeline stage B manually if previous stage A failed, else execute stage B automatically?

Consider GitLab CI/CD pipeline consisting of two consequent stages: A and B.

If stage A succeeds, I want stage B to be executed automatically. But if stage A fails, I don't want stage B to be executed automatically, but still have a possibility to force execute stage B manually.

How can I achive that?

There are at least two ways I can see to achieve that (when your pipeline fails you will need to manually trigger whole pipeline again, not just one stage):

  1. Mark job in stage B when: always to execute job regardless of the status of jobs from prior stages.
firstFailingJob:
  stage: test
  script:
    - echo I will always fail
    - exit 1

secondExecuteWhenManualTrigger:
  stage: deploy
  script:
    - echo I should run even when first failed when triggered manually
  rules:
    - if: '$CI_PIPELINE_SOURCE == "web"'
      when: always
    - when: on_success

Note that the result of whole pipeline will be failed, as ilustrated below. Always execute second job for manual trigger 2. Mark possibly failing job with allow_failure: true to fail without impacting the rest of the CI suite.

firstFailingJob:
  stage: test
  script:
    - echo I will always fail
    - exit 1
  rules:
    - if: '$CI_PIPELINE_SOURCE == "web"'
      allow_failure: true
    - allow_failure: false
...

Result of whole pipeline will be passed with warnings as ilustrated below. Allow failure

$CI_PIPELINE_SOURCE == "web" means pipeline has been triggered from GitLab gui Project page -> CI/CD -> Run Pipeline. You can always setup different conditions with any variable custom or predefined.

You can't do that with stages.

Jobs of the next stage are run after the jobs from the previous stage complete successfully.

That's per https://docs.gitlab.com/ee/ci/yaml/#stages

There is no way to make a stage be manually triggered.
