Microk8s: publishing the dashboard (reachable from remote/internet)

 

If you enable the dashboard on a microk8s cluster (or single node) you can follow this tutorial: https://microk8s.io/docs/addon-dashboard

The problem is, the command

microk8s kubectl port-forward -n kube-system service/kubernetes-dashboard 10443:443

has to be reexecuted every time you restart your node, which you use to access the dashboard.

A better configuration can be done this way: Run the following command and change 

type: ClusterIP -->   type: NodePort

kubectl -n kube-system edit service kubernetes-dashboard 

# Please edit the object below. Lines beginning with a '#' will be ignored,
# and an empty file will abort the edit. If an error occurs while saving this file will be
# reopened with the relevant failures.
#
apiVersion: v1
kind: Service
metadata:
  annotations:
    kubectl.kubernetes.io/last-applied-configuration: |
      {"apiVersion":"v1","kind":"Service","metadata":{"annotations":{},"labels":{"k8s-app":"kubernetes-dashboard"},"name":"kubernetes-dashboard","namespace":"kube-system"},"spec":{"ports":[{"port":443,"targetPort":8443}],"selector":{"k8s-app":"kubernetes-dashboard"}}}
  creationTimestamp: "2021-01-22T21:19:24Z"
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kube-system
  resourceVersion: "3599"
  selfLink: /api/v1/namespaces/kube-system/services/kubernetes-dashboard
  uid: 19496d44-c454-4f55-967c-432504e0401b
spec:
  clusterIP: 10.152.183.81
  clusterIPs:
  - 10.152.183.81
  ports:
  - port: 443
    protocol: TCP
    targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard
  sessionAffinity: None
  type: ClusterIP
status:
  loadBalancer: {}

Then run

root@ubuntu:/home/ubuntu# kubectl -n kube-system get service kubernetes-dashboard
NAME                   TYPE       CLUSTER-IP      EXTERNAL-IP   PORT(S)         AGE
kubernetes-dashboard   NodePort   10.152.183.81   <none>        443:30713/TCP   4m14s

After that you can access the dashboard over the port which is given behind the 443: - in my case https://zigbee:30713
