Argocd 배포 notication을 수정하자 (oncePer)

helm이 변경되면서 신규commit이 발생하게 되었다.
이미지가 변경되지 않았는데, Slack 알림이 울린다.

옵션중에 onceper가 있는데 이미 세팅되어있다

• 정해진 값이 변경될때 한번만 실행한다
• onceper를 수정해보자.

기존 oncePer

• app.status.sync.revision

기존 값은 repository를 바라보고 최신 commit에 의해 변경됨
현재는 ci 이후 helm chart에 image tag를 수정하는 방식이라 helm이 수정될때마다 발생함. 따라서 image tag값이 아닌 다른 값을 수정해도 발생하게됨.

수정 oncePer

• app.status.operationState.operation.sync.revision

수정된 값은 배포되면 deployment에 의해 리비전이 결정됨
image가 변경되었을때 deployment의 rs가 생기면서 발생

참고

• ArgoCD application.yaml 확인.
