Error¶

rpc error: code = Unknown desc = authentication required¶

• add the user/pass for the helm chart repo to argocd

• or the user/pass(token) is not correct

argocd repositories connection status failed¶

https://levelup.gitconnected.com/connect-argocd-to-your-private-github-repository-493b1483c01e

could not read Username for 'https://github.com': No such device or address¶

There are two ways to check out code from Github:

• with user name/password,

• authenticate with an SSH key

In argocd, the credentials template still use https not git@ but the credentials are provided via a pair of ssh keys.

when change the url to git@ the error became authentication required. Maybe the ssh key is not correct??? The private key should not be base64 encoded!!!

If the repositories are connected seccussfully but the applications still show the error, the AppProject sourceRepos must also use the git@ format when the authentication is via ssh.

the server could not find the requested resource¶

The apiVersion for the app such Cronjob might be old and should be updated.

Argo will not report helm chart rendering error¶

So the pods are simply not deployed.

Argo renders templates first, then contacts the apiserver¶

In a helm chart, if the apiVersion depends on the k8s version. This could be go wrong

{{- if .Capabilities.APIVersions.Has "policy/v1" }}
apiVersion: policy/v1
{{- else }}
apiVersion: policy/v1beta1
{{- end }}

argocd outofsync Pending deletion¶

one pod is waiting for another pod but the other one was dead.

auto-sync will wipe out all resources¶

if disable a deployment, argo-cd will show:

Skipping sync attempt to xyz: auto-sync will wipe out all resources

Solutions:

• manually sync with prune first

• change config: https://github.com/argoproj/argo-cd/issues/10987

    automated: 
      prune: true 
      allowEmpty: true
      selfHeal: true
