Unable to delete resource: namespaces "default" is forbidden: this namespace may not be deleted

[juliohm1978]

While experimenting with argocd, I included the following resource in the git repo:

apiVersion: v1
kind: Namespace
metadata:
  name: default

In retrospect, I just wanted to keep the namespace annotations and labels synched with my git repo.

Now, I am unable to delete this resource from argocd because Kubernetes refuses the delete the default namespace.

The yaml resource has been removed from the git repo, but I am unable to sync argocd.

Is there a way to remove the resource reference from argocd without having to actually delete the resource from the cluster?

I guess to "unmanage" that resource, you would need to patch out the tracking label that Argo CD has applied to the live resource. Given a standard Argo CD configuration and that the resource was deleted in Git, you can run:

kubectl patch ns default --type=json -p='[{"op":"remove", "path":"/metadata/labels/app.kubernetes.io~1instance"}]

Thank you! That does the trick and causes argocd to ignore the resource.

Best regards!

I did it in the following way

kubectl label ns default argocd.argoproj.io/instance-
