If RBAC is not enabled access the dashboard using the token retrieved with:

microk8s kubectl describe secret -n kube-system microk8s-dashboard-token

Use this token in the https login UI of the kubernetes-dashboard service.

In an RBAC enabled setup (microk8s enable RBAC) you need to create a user with restricted
permissions as shown in:
https://github.com/kubernetes/dashboard/blob/master/docs/user/access-control/creating-sample-user.md
