Helm Release stuck in Uninstalling state
Oct 13
I was trying to uninstall a helm release in my AKS cluster using helm uninstall RELEASE_NAME but seems like it failed. The failure happened because for some reason all of the nodes in my cluster went in a not ready state when I used helm uninstall.
Since then, I got all the nodes to get back up and running and the cluster is functioning as it should. Now, when I do try helm list, I don't get to see this release present anymore, but doing a helm list -a shows me that the state of the release is still in uninstalling state. I have tried quite a few things, but it has been stuck there now for the last 3-4 days.
A few things that I tried was to use helm uninstall RELEASE_NAME, helm delete --purge RELEASE_NAME but these commands throw an error because the release is already in uninstalling state. I tried modifying the helm secrets in the cluster for this specific release but that didn't help either. Helm3 is being used so it is not like I can restart the tiller pod to maybe stabilize this.
Does Helm3 use some kind of a finalizer mechanism which can be modified to rectify this or
is there no alternate way in which I can perhaps try to delete this release? I want to use the same release name for the specific API in the future too.
Any help will be really appreciated.

Based on the discussion, the following steps resolve the issue.
helm hist releasename
helm rollback releasename versionnumber-with-status-deployed
if this did not help, then delete secret for each version
helm hist releasename
kubectl get secrets
k delete secrets sh.helm.release.v1.name.VERSION-N
