unable to launch kubectl dashboard on Mac

8/9/2019

I have deployed minikube on MacOS using the instructions here https://kubernetes.io/docs/tasks/tools/install-minikube/

The brew install was ok and the minikube status shows

  $ minikube status
  host: Running
  kubelet: Running
  apiserver: Running
  kubectl: Correctly Configured: pointing to minikube-vm at 192.168.99.102

I am able to interact with the cluster using kubectl

$kubectl run hello-minikube --image=k8s.gcr.io/echoserver:1.10 --port=8080

Viewing the pods is also ok

$kubectl get pod
 NAME                              READY   STATUS    RESTARTS   AGE
 hello-minikube-856979d68c-glhsx   1/1     Running   0          18m

But when i try to launch the kubectl dashboard, i get 503 error

$minikube dashboard
Temporary Error: unexpected response code: 503
Temporary Error: unexpected response code: 503

The Dashboard service seems to present

 $kubectl -n kube-system get svc -o wide
NAME                   TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)                  AGE     SELECTOR
kube-dns               ClusterIP   10.96.0.10       <none>        53/UDP,53/TCP,9153/TCP   3h19m   k8s-app=kube-dns
kubernetes-dashboard   ClusterIP   10.109.210.119   <none>        80/TCP                   119m    app=kubernetes-dashboard

below is the kubectl version info

 $kubectl version
Client Version: version.Info{Major:"1", Minor:"15", GitVersion:"v1.15.2", GitCommit:"f6278300bebbb750328ac16ee6dd3aa7d3549568", GitTreeState:"clean", BuildDate:"2019-08-05T16:57:42Z", GoVersion:"go1.12.7", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"15", GitVersion:"v1.15.2", GitCommit:"f6278300bebbb750328ac16ee6dd3aa7d3549568", GitTreeState:"clean", BuildDate:"2019-08-05T09:15:22Z", GoVersion:"go1.12.5", Compiler:"gc", Platform:"linux/amd64"}

Any pointers on what is missing ? How to get the dashboard working

Thanks

Finally able to solve this issue with instructions from GitHub issues https://github.com/kubernetes/minikube/issues/4352

Basically, with these commands

minikube stop
minikube start --extra-config=apiserver.authorization-mode=RBAC
kubectl create clusterrolebinding add-on-cluster-admin --clusterrole=cluster-admin --serviceaccount=kube-system:default
minikube dashboard

Check kubectl cluster-info, you can find more here

kubectl -n kube-system port-forward svc/kubernetes-dashboard 8080:80

Your dashboard should be accessible on http://localhost:8080, keep in mind that the dashboard is deprecated so you can check octant.

Try $ minikube dashboard command. It will open a new tab in your default browser showing the minikube dashbord.
