Learn how to configure the access to microk8s' dashboard

We assume that microk8s is already installed on your system and you are using a Linux server.

Check if dashboard is available

Run the following command to see if dashboard is available.

microk8s status

You should get something like this:

microk8s is running
high-availability: no
  datastore master nodes: 127.0.0.1:19001
  datastore standby nodes: none
addons:
  enabled:
    ...
  disabled:
    ...
    dashboard            # (core) The Kubernetes dashboard
    ...

Enable the dashboard

Run the following command to enable the addon dashboard:

microk8s enable dashboard

You should get something like this:

Infer repository core for addon dashboard
Addon core/dashboard is enabled

Check if the dashboard is running

Run the following command:

microk8s kubectl -n kube-system get svc

You should see the service for dashboard.

NAME                   TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)   AGE
kubernetes-dashboard   ClusterIP   10.20.30.40   <none>        443/TCP   1h

Make the dashboard accessible at all times

Run the following commands using the file k8s-dashboard-lb.yaml from this repo.

microk8s kubectl apply -f k8s-dashboard-lb.yml
microk8s kubectl -n kube-system get svc

You should see the new service and at which port is exposed:

NAME               TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)         AGE
k8s-dashboard-lb   LoadBalancer   10.152.183.81   <pending>     443:30123/TCP   1m

Now you can access it at https://127.0.0.1:30123.

Authentication

To be able to login in dashboard you need to create a token with the following command:

microk8s kubectl create token default > k8s-token.txt

The token will be saved in k8s-token.txt file. You need to copy it from there and use it in the browser.

Using nginx as proxy

You can use the nginx.conf file as example how to access the dashboard from internet using nginx as web server.

Replace k8s.<YOUR-DOMAIN> with your hostname and <MAPPED_PORT_443> with the exposed port (in our example was 30123).

Don't forget also to enable the HTTPS for it.
