I have installed fresh Kubernetes 1.6.2 master on a single host and now trying to start Flannel using https://github.com/coreos/flannel/blob/master/Documentation/kube-flannel.yml
The pod does not come up:
$ kubectl get pods kube-flannel-ds-l6gn4 --namespace kube-system
NAME READY STATUS RESTARTS AGE
kube-flannel-ds-l6gn4 1/2 CrashLoopBackOff 36 2h
$ kubectl logs kube-flannel-ds-l6gn4 --namespace kube-system kube-flannel
E0427 15:35:52.232093 1 main.go:127] Failed to create
SubnetManager: error retrieving pod spec for 'kube-system/kube-flannel-ds-l6gn4': the server does not allow access to the requested resource (get pods kube-flannel-ds-l6gn4)
I've also tried this using the default serviceaccount, but it won't come up.
If you are using the RBAC authorizer, you also need to create https://github.com/coreos/flannel/blob/master/Documentation/kube-flannel-rbac.yml to set up the role and permissions for the flannel service account
