I've just created a new kubernetes cluster. The only thing I have done beyond set up the cluster is install Tiller using helm init and install kubernetes dashboard through helm install stable/kubernetes-dashboard.

The helm install command seems to be successful and helm ls outputs:

NAME                    REVISION        UPDATED                         STATUS          CHART                           APP VERSION     NAMESPACE

However after waiting a few minutes the deployment is still not ready.

Running kubectl get pods shows that the pod's status as CrashLoopBackOff.

NAME                                    READY   STATUS             RESTARTS   AGE
exhaling-ladybug-kubernetes-dashboard   0/1     CrashLoopBackOff   10         31m

The description for the pod shows the following events:

And the logs show the following panic message

panic: secrets is forbidden: User "system:serviceaccount:default:exhaling-ladybug-kubernetes-dashboard" cannot create resource "secrets" in API group "" in the namespace "kube-system"

Am I doing something wrong? Why is it trying to create a secret somewhere it cannot?

Is it possible to setup without giving the dashboard account cluster-admin permissions?
