How to sign in kubernetes dashboard?

Question

I just upgraded kubeadm and kubelet to v1.8.0. And install the dashboard following the official document.

$ kubectl apply -f https://raw.githubusercontent.co         


        

Answer 1

If you don't want to grant admin permission to dashboard service account, you can create cluster admin service account.

$ kubectl create serviceaccount cluster-admin-dashboard-sa
$ kubectl create clusterrolebinding cluster-admin-dashboard-sa \
  --clusterrole=cluster-admin \
  --serviceaccount=default:cluster-admin-dashboard-sa

And then, you can use the token of just created cluster admin service account.

$ kubectl get secret | grep cluster-admin-dashboard-sa
cluster-admin-dashboard-sa-token-6xm8l   kubernetes.io/service-account-token   3         18m
$ kubectl describe secret cluster-admin-dashboard-sa-token-6xm8l
