I followed the Kubernetes docs for setting up a single node cluster as a Docker container. I now have Kubernetes running on a remote Linux VM (say, mykube01.example.com).

I then downloaded and installed kubectl locally on my Mac laptop. I can run kubectl version and it verifies I have installed the correct version.

I then went to configure kubectl by following this doc and created the following ~/.kube/config file:

 apiVersion: v1
 clusters:
 - cluster:
      api-version: v1
      server: http://mykube01.example.com:8080
      name: testkube

When I run kubectl cluster-info I get:

Kubernetes master is running at http://mykuber01.example.com:8080

But when I run kubetctl get nodes I get:

The connection to the server mykube01.example.com:8080 was refused - did you specify the right host or port?

Any ideas where I'm going awry? I want to get to the point where I can keep going with that first Kubernetes doc and deploy nginx to the 1-node cluster via:

kubectl -s http://mykube01.example.com:8080 run-container nginx --image=nginx --port=80

But I can't do that until I get kubectl configured properly and correctly connecting to my remote "cluster".
