문제 재현

로컬에서 AWS CLI으로 배포하기

aws deploy create-deployment 
--application-name what-is-quality-symbolic-test 
--deployment-config-name CodeDeployDefault.AllAtOnce 
--deployment-group-name what-is-quality-symbolic-test 
--file-exists-behavior OVERWRITE
--description "배포 설명" 
--s3-location bucket=배포할파일버킷위치,bundleType=zip,eTag=배포파일eTag,key=배포파일명

AWS CLI - Deploy Create Deployment

재현 현상

서버에서 Symlink 파일을 직접 생성한 후, 동일한 경로에 Symlink 파일을 만들어서 배포 시도.

OVERWRITE 옵션 영향범위 테스트 케이스

depth 1	depth 2	condition	변경전	변경후
appspec > source 하위 폴더 안에 Symlink 파일/폴더가 있는 경우	파일 Symlink인 경우	source 파일이 Symlink이고, destination에 같은 이름의 일반 파일 / Symlink 파일이 있는 경우	오류남	정상처리
	폴더 Symlink인 경우	source 폴더가 Symlink이고, destination에 같은 이름의 일반 폴더가 있는 경우	오류안남. 하지만 Symlink 복사안됨	오류안남. Symlink 복사안됨. OVERWRITE된 폴더를 삭제하여, 재배포를 해도 해당 폴더가 삭제되지 않음
		source 폴더가 Symlink이고, destination에 같은 이름의 Symlink 폴더가 있는 경우	오류남	정상처리
		source 폴더가 Symlink이고, destination에 같은 이름의 일반 파일이 있는 경우	오류남	정상처리
appspec > source가 Symlink인 경우	파일 Symlink인 경우	-	오류남	정상처리
	폴더 Symlink인 경우	-	오류남	오류안남. Symlink 복사안됨.

요약

• Symlink 함수에 force 옵션을 추가해도 아래와 같은 오류가 여전히 발생한다.
  • Symlink 폴더를 배포할 때, 동일 경로에 일반 폴더가 서버에 존재하는 경우
    • 오류가 나지는 않으나, Symlink 복사되지 않는다.
    • OVERWRITE된 폴더를 삭제하여, 재배포를 해도 해당 폴더가 삭제되지 않는다
