<p>I have Kubernetes 1.8.7 cluster deployed on AKS. I am trying to install NGINX ingress controller using help (helm install stable/nginx-ingress --namespace kube-system). I init helm using helm init --service-account default. 
I am getting following error </p>

<blockquote>

<p>This command was working till yesterday and I have no changes done but it stopped working this morning. Aks doesn't support RBAC yet in my understanding and so created a role and mapping to cluster admin was futile. Any suggestions </p>

<p>Add --version 0.18.1 to your <code>helm install</code> or <code>helm upgrade</code> command. Still getting to the bottom of this, but the culprit is <a href="https://github.com/kubernetes/charts/pull/5169" rel="nofollow noreferrer">https://github.com/kubernetes/charts/pull/5169</a></p>
