Helm V3 - Cannot find the official repo

From Helm Blog -

On November 13, 2020 the stable and incubator charts repository will reach the end of development and become archives. You can find that many of the charts have moved to other, community managed, repositories. You can discover these on the Artifact Hub.

The best way to discover a chart by searching the Artifact Hub. And if you select nginx-ingress from ORG Helm, you can see the instruction for adding a repo.

helm repo add nginx-stable https://helm.nginx.com/stable

The stable repository is hosted on https://kubernetes-charts.storage.googleapis.com/. So, try the following:

helm repo add stable https://kubernetes-charts.storage.googleapis.com/

EDIT 2020-11-16: the above repository seems to have been deprecated. The following should now work instead:

helm repo add stable https://charts.helm.sh/stable

Be aware that Helm v3 does not have the use of Tiller.

1. Install Helm v3:

curl https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3 > get_helm.sh
chmod 700 get_helm.sh
./get_helm.sh

2. Install Ingress-Nginx:

helm repo add stable https://kubernetes-charts.storage.googleapis.com/
helm install my-nginx stable/nginx-ingress --set rbac.create=true
