Step 1#
Install the helm-2to3
plugin
helm3 plugin install https://github.com/helm/helm-2to3

kubectl label $KIND $NAME app.kubernetes.io/managed-by=Helm
KIND=ClusterRole
NAME=reloader-reloader-role
RELEASE=reloader
NAMESPACE=kube-system
kubectl annotate $KIND $NAME meta.helm.sh/release-name=$RELEASE
