• 깃허브 액션은 최소시간 5분단위로 실행시켜준다. 더 작은 단위면 안됨.

  https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#schedule

그런데 제 시간에 실행되지 않는 경우가 많다.

• 특정 브랜치에서 cron push한다고 해서 cron 실행 불가.

main 브랜치에 cron 파일이 생성되어야 cron이 실행이 된다.

가장 최신 tag 가져오기

• steps.<id\>.outputs.tag 사용해서 checkout해서 사용하면 된다.

- name: Get latest tag
        id: latest_tag
        run: |
          git fetch --depth=1 origin "+refs/tags/*:refs/tags/*"
          latest_commit=$(git rev-list --tags --max-count=1)
          latest_tag=$(git describe --tags "$latest_commit")
          echo "::set-output name=tag::$latest_tag"
      
      - name: Display latest tag
        run: |
          echo "Latest tag is ${{ steps.latest_tag.outputs.tag }}"
      - uses: actions/checkout@v3
        with:
          ref: ${{steps.latest_tag.outputs.tag}}

성공 실패

success() 또는 failure() 사용하면 된다.

특정 step에서의 실패에 따른 슬랙 메시지를 다르게 하고 싶으면

if문을 사용하면 된다.

if: failure() && steps.test.conclusion == 'failure'

여기서 failure는 무조건 작은 따움표로 감싸야 한다. 아니면 에러발생.

특정 steps가 갖는 컨텍스트 : https://docs.github.com/ko/actions/learn-github-actions/contexts
