Role creation failed on GKE cluster

[levlas]

I have just tried to install fluentbit as DS on a GKE cluster (v1.9.2), followed the README,

I created the namespace and the service account, but when I tried to create the role I got an error message:
Error from server (Forbidden): error when creating "https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/fluent-bit-role.yaml": clusterroles.rbac.authorization.k8s.io "fluent-bit-read" is forbidden: attempt to grant extra privileges: https://gist.github.com/levlas/c956099b7c9753decf5d97d8a7cb26dd

The solution was the role binding of GKE user to cluster-admin role: fluent/fluentd-kubernetes-daemonset#14 (comment)

Would you add that step to the docs?
