I installed kubernetes and it all looks alright I think. ( note that those are outputs after editing a file below, changing to NodePort)

sudo kubectl get deployment kubernetes-dashboard -n kubernetes-dashboard
NAME                   READY   UP-TO-DATE   AVAILABLE   AGE
kubernetes-dashboard   1/1     1            1           85m

and

Im following a tutorial to install Kubernetes dashboard. https://k21academy.com/docker-kubernetes/kubernetes-dashboard/ This command will NOT show Kubernetes dashboard, it will show only kubernetes.

In his example it showed kubernetes Metrics scraper and kubernetes dashboard, when I do it it only shows kubernetes. I don't know why

sudo kubectl get svc

    NAME         TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
    kubernetes   ClusterIP   10.96.0.1    <none>        443/TCP   44m

And because of that I can only edit kubernetes with the following command, but I don't want to edit kubernetes. I want to edit service/kubernetes-dashboard instead.

Works but not the correct file I think:

sudo kubectl edit service/kubernetes

Does not work:

sudo kubectl edit service/kubernetes-dashboard

So had used this command instead to edit Kubernetes-dashboard but im not sure if they are the same files:

sudo kubectl -n kubernetes-dashboard edit svc kubernetes-dashboard

Question Nr 1.

Why is kubernetes Dashboard and metrics scraper not showing up when I use this command? And how do I make it show up?

sudo kubectl get svc

Question Nr 2.

Are those two commands editing the same file?

sudo kubectl edit service/kubernetes-dashboard

And

sudo kubectl -n kubernetes-dashboard edit svc kubernetes-dashboard

Question Nr 3.

If the file I edited with : sudo kubectl -n kubernetes-dashboard edit svc kubernetes-dashboard Is not the same files that is being edited when I use this command:

sudo kubectl edit service/kubernetes-dashboard

How do I fix or revert the changes I made with the first command if im not sure how it previously looked like? Can I delete the file somehow and regenerate it after applying the recommended?

Im trying to install the dashboard and im not getting an external IP.
