1. Secrets 객체로 저장된 리포지토리 정보를 확인합니다. 

~/environment $ kubectl get secrets -n argocd
NAME                                        TYPE                                  DATA   AGE

~/environment $

2. repo-xxxxx로 된 Secrets의 내용을 확인합니다.

8021:~/environment $ kubectl get secret repo-1467931201 -n argocd -o yaml
apiVersion: v1
data:
  password: d2pzdGtzdGxmMTI=
  type: Z2l0
  url: aHR0cHM6Ly9naXRsYWIubW5nLnJlZmluZWh1Yi5jb20vZGV2b3BzL3JlZmluZS13b3JrL2xzci1ncm50LWFwaS5naXQ=
  username: amVua2lucw==
kind: Secret
metadata:
  annotations:
    managed-by: argocd.argoproj.io
  creationTimestamp: "2021-09-16T15:33:44Z"
  labels:
    argocd.argoproj.io/secret-type: repository
  name: repo-1467931201
  namespace: argocd
  resourceVersion: "28308"
  uid: 731edae6-f2cf-46c7-9150-49ef0ebdabbe
type: Opaque
~/environment $

3. url에 나온 값을 base64로 디코딩해서 git 주소를 확인합니다.

~/environment $ echo aHR0cHM6Ly9naXRsYWIubW5nLnJlZmluZWh1Yi5jb20vZGV2b3BzL3JlZmluZS13b3JrL2xzci1ncm50LWFwaS5naXQ= | base64 -d
https://gitlab.test.com/devops/test.git

4. 3번을 방법은 통해서 비밀번호를 변경하고자 리포지토리를 찾고 해당 ConfigMap에 명시된 password 값을 업데이트 합니다. (base64로 인코딩한 값으로 넣어줍니다)

e.g. 비밀번호를 asdf1234로 변경할 경우 password 값에 YXNkZjEyMzQK를 넣어줍니다.

~/environment $ echo asdf1234 | base64
YXNkZjEyMzQK
~/environment $
