Helm V3 - Cannot find the official repo
Solution 1:
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
Solution 2:
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
