kubernetes - kube-dns remains in "ContainerCreating" -


i manually installed k8s-1.6.6 , deployed calico-2.3(uses etcd-3.0.17 kube-apiserver) , kube-dns on baremetal(ubuntu 16.04).

it dosen't have problems without rbac.

but, after applying rbac adding "--authorization-mode=rbac" kube-apiserver. couldn't apply kube-dns status remains in "containercreating".

i checked "kubectl describe pod kube-dns.."

i found cause. issue not related kube-dns. missed out applying clusterrole/clusterrolebinding, before deplying calico
