How to delete(uninstall) helm chart on specific resource

Question

I have installed redis. The default given name to me is plinking-narwhal. Now I would like to install a service with my assigned name. But first I want to remove the existing one. I had tried deleting them without success.

$ kubectl get all

You probably need:

$ helm delete redis

or if you completely want to remove the release:

$ helm delete redis --purge

stable/redis is not allowed as an expression because of the slash(/)

If you'd like to see the name of the releases you can simply run:

$ helm list -aq

add `--purge` to the delete command if you want to reuse the release name – Dhanesh Oct 24 '19 at 13:53

@holms since Helm 3, there is no `--purge` option as [purging is now the default](https://stackoverflow.com/a/59210923/992887) – RichVel Mar 01 '21 at 16:55

Helm delete command is renamed to helm uninstall. So you probably have to use:

helm uninstall redis
