Helm | Tiller permissions fix

To fix this error: 
  release cicd failed: namespaces "default" is forbidden: User "system:serviceaccount:kube-system:default" cannot get namespaces in the namespace "default": Unknown user "system:serviceaccount:kube-system:default"

Use these commands:

$ kubectl create serviceaccount --namespace kube-system tiller
  serviceaccount "tiller" created

$ kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
  clusterrolebinding "tiller-cluster-rule" created

$ kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}' 
  deployment "tiller-deploy" patched


Then run below to check it :

$ helm list
$ helm repo update
