Fixed Kubernetes Issue, Could not Connect to Kubeserver

Small learning, I could not connect to my kubernetes cluster. I downloaded the kubeconfig file (~/.kube/config) from the kubernetes cluster. I had to modify it, because it pointed to localhost (127.0.0.1).

apiVersion: v1
clusters:
  - cluster:
      certificate-authority-data: ...
      server: NAMEHERE
    name: default
[...]

Here is what I did wrong: I used a DNS name (kubernetes.local:6443) instead of an ip-address.

Took me a long time to figure out that I needed an ip address here.
