Gitlab ci run job on master with release tag only

问题

I would like to build docker image on master branch only when release tag is set. This is my .gitlab.ci:

build:
  rules:
    - if: '$CI_COMMIT_TAG != null && $CI_COMMIT_REF_NAME == "master"'
  script:
    - echo "Building $IMAGE:${CI_COMMIT_TAG}"

This does not work, I merged to master and release tag, but the build job did not even start.

I also tried with only section:

build:
  only:
    - master
    - tags
  script:
    - echo "Building $IMAGE:${CI_COMMIT_TAG}"

This run everytime, even when CI_COMMIT_TAG does not exists. Is there a way, how to force to run job only if CI_COMMIT_TAG exists on master branch?

回答1:

With

build:
  only:
    - tags

you can run a job only when a tag was set (or pushed). If you have master in there, it runs on every commit on master. Without master it only runs after setting a tag.
