CI_COMMIT_TAG alternative

README.md

  script:
    - echo hello cicd
  rules:
    - if: "($CI_PIPELINE_SOURCE == 'pipeline' || $CI_PIPELINE_SOURCE == 'web') && $CI_COMMIT_TAG != null && $CI_COMMIT_BRANCH == 'main' "

since above rule with CI_COMMIT_TAG is only triggered when tag is pushed to gitlab, one can use the below to execute commands only when a commit is tagged via pipeline.

  script:
    - |
      if [[ $(expr length $(git describe --exact-match --tags)) > 0 ]] && [[ $CI_COMMIT_BRANCH = 'main' ]]; then
        echo $CI_COMMIT_SHORT_SHA is tagged as $(git describe --exact-match --tags)
        echo hello cicd  
      else
        echo no tags found for commit $CI_COMMIT_SHORT_SHA
      fi
  rules:
    - if: "($CI_PIPELINE_SOURCE == 'pipeline' || $CI_PIPELINE_SOURCE == 'web')"
