ArgoCD ECR updater

If you are using a private AWS ECR repository to store helm charts, the stored password will become expired at latest in 12h.
The argocd-ecr-updater will refresh the token in defined interval.

The updater will only consider secrets with these labels for update.

kind: Secret
metadata:
  labels:
    argocd-ecr-updater: enabled
    argocd.argoproj.io/secret-type: repository

The data field password will be updated with a fresh token from AWS ECR.

To give ArgoCD permission to get the ECR token create IRSA role with following permissions

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "",
            "Effect": "Allow",
            "Action": [
                "ecr:GetAuthorizationToken",
                "ecr:DescribeRepositories"
            ],
            "Resource": "*"
        }
    ]
}

This token is valid to authenticate against any registry id, the user has access. Depending on how you set the trust relationship on ECR repository policy.

Finally annotate the service account with your role arn

serviceAccount:
  annotations:
    eks.amazonaws.com/role-arn: arn:aws:iam::123456:role/argocd-ecr-updater

      --kubeconfig string   kubernetes config file
