[정보] ingress-nginx argocd 설정 파일(redirection loop)

문제발견

ingress-nginx를 사용중에 argocd를 연결하니 307 redirection loop가 발생 했다.

 

해결방법

공식 홈페이지를 찾아보니 무조건 backend는 https로 접속하는 metadata:annotation을 추가로 달아줬다.

    # If you encounter a redirect loop or are getting a 307 response code
    # then you need to force the nginx ingress to connect to the backend using HTTPS.
    #
    nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
