did you specify the right host or port? error on Kubernetes : <p>I have followed the helloword tutorial on <a href="http://kubernetes.io/docs/hellonode/" rel="noreferrer">http://kubernetes.io/docs/hellonode/</a>. </p>

<p>When I run:</p>

<pre><code>kubectl run hello-node --image=gcr.io/PROJECT_ID/hello-node:v1 --port=8080
</code></pre>

<p>I get: 
The connection to the server localhost:8080 was refused - did you specify the right host or port?</p>

<p>Why do the command line tries to connect to localhost? </p>
