Describe the bug

I deployed the ArgoCD RBAC Operator using the Helm chart in local Minikube version 1.34.0. While the operator deploys successfully, when I try to apply the ArgoCDRole and ArgoCDBinding manifests results in the following error:

E0108 22:55:14.417632 1 reflector.go:150] pkg/mod/k8s.io/[email protected]/tools/cache/reflector.go:232: Failed to watch *v1.ConfigMap: unknown (get configmaps)

This might not be a bug, but I'm trying to understand what I'm doing wrong here.

Attaching the complete log for reference:

To Reproduce

  • Deploy the ArgoCD RBAC Operator using the Helm chart.
  • Create the ArgoCDRole and ArgoCDBinding manifests in the same namespace (argocd).

Expected behavior

ConfigMap argocd-rbac-cm created after the ArgoCDRole and ArgoCDRoleBinding has been reconciled

Additional context

  • The argocd namespace exists and the Crs are created in the same namespace
  • Image tag v0.1.6

Thanks for the help!

Hi @ximena9201, thank you for reaching out. Try to create the argocd-rbac-cm first, before applying the manifests. The operator doesn't create the RBAC-CM, since it's a responsibility of Argo CD.

Yes I forgot to mention it, I previously deployed an Argo instance so the ConfigMap is already in place. I assume the operator should overwrite - but is not doing it

ah alright, i'll look into it :)

the operator is not overwritting the CM, to ensure compatibility.

@ggkhrmv It's behaving more like an append to the ConfigMap rather than an overwrite.? and thanks by the way for looking in to this

@ximena9201 yes in a way, when a role gets created, the operator appends a key in the form of policy.<role.Namespace>.<role.Name>.csv to the ConfigMap :)

@ggkhrmv It seems like the issue was due to missing data in the ConfigMap argocd-rbac-cm, specifically (None) values from deploying ArgoCD from scratch. There was no RBAC data, causing reconciliation problems. The fix was to populate the ConfigMap, which resolved the issue

@ximena9201 sorry I didn't have time to look into it yet :/

What exactly was missing? Is this something we could fix with the Operator, or does the issue exist due to Argo CD deployment?
