Kubernetes Dashboard

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/v2.0.0-beta4/aio/deploy/recommended.yaml

Login to your dashboard

Proxy the remote kubernetes dashboard to localhost:

$ kubectl proxy

Visit:

http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/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
