The kubernetes dashboard is optional but very helpful for debugging. If you want to install it, you have to do so only once per cluster:
# in folder deployment/digital-ocean/
$ kubectl apply -f dashboard/
$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/master/aio/deploy/recommended/kubernetes-dashboard.yaml
Login to your dashboard
Proxy the remote kubernetes dashboard to localhost:
Visit:
http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
You should see a login screen.
To get your token for the dashboard you can run this command:
$ kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')
It should print something like:
Name: admin-user-token-6gl6l
Namespace: kube-system
Labels: <none>
Annotations: kubernetes.io/service-account.name=admin-user
kubernetes.io/service-account.uid=b16afba9-dfec-11e7-bbb9-901b0e532516
Type: kubernetes.io/service-account-token
