Using gcr.io/google_containers/nginx-ingress-controller:0.9.0-beta.7 the nginx-controller needs to handle leader-election via configmaps. To perform the leader-election the nginx-controller needs to have the appropiate RBAC permissions. Previously to this fix, the following errors occured: - cannot get configmaps in the namespace "NAMESPACE_PLACEHOLDER". (get configmaps ingress-controller-leader-nginx) - initially creating leader election record: User "system:serviceaccount:NAMESPACE_PLACEHOLDER" cannot create configmaps in the namespace "NAMESPACE_PLACEHOLDER". (post configmaps) fix ingress rbac roles There was 2 things that the current IC (0.9 beta7) needs. The ClusterRole was missing `get nodes`: ``` RBAC DENY: user "system:serviceaccount:kube-system:nginx-ingress-controller" groups [system:serviceaccounts system:serviceaccounts:kube-system system:authenticated] cannot "get" resource "nodes" named "xxx" cluster-wide ``` The Role was missing `update configmaps`: ```RBAC DENY: user "system:serviceaccount:kube-system:nginx-ingress-controller" groups [system:serviceaccounts system:serviceaccounts:kube-system system:authenticated] cannot "update" resource "configmaps" named "ingress-controller-leader-nginx" in namespace "kube-system"``` removed update configmap because of #798 rebased on master, moved get nodes to own rule added get nodes to cluster permissions
