How to delete(uninstall) helm chart on specific resource

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

redis kubernetes kubernetes-helm

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

helm uninstall redis
