Gitlab CI Variables 환경변수 알아보기

ref : Gitlab CI > Variables

GitLab CI를 사용하여 Runner를 쓸 때,

기본적으로 세팅되어 있는 환경변수를 쓰면 편리한 경우가 있다

 ex ) 동일한 컨테이너를 쓰는데 현 프로젝트를 알아야 하는 경우

CI_PROJECT_NAME

 ex )  정규표현식으로 걸러진 tag에만 수행하도록 설계된 Pipeline에서 트리거가 걸린 Tag의 값을 확인할 때

CI_COMMIT_TAG

 ex )  채팅앱으로 Pipeline Status View 연계 링크에 필요한 Pipeline 번호를 확인할 때

CI_PIPELINE_ID

( 쉘에서  이렇게 "$CI_PIPELINE_ID" 변수의 값을 쓰는 것이다 )

여하튼, 여러가지 경우에 요긴하다

Gitlab은 문서가 정말 잘 만들어져 있어 자동화하기에 최고다
