title: kubectl top deosn't work
body: <p>I'm using <code>kubernetes 1.11.0</code> and running heapster. When I run </p>
  
  <pre><code>kubectl top pod
  </code></pre>
  
  <p>It will show error</p>
  
  <pre><code>Error from server (ServiceUnavailable): the server is currently unable to handle the request (get services http:heapster:)
  </code></pre>
  
  <p>while I have installed heapster already</p>
  
  <pre><code>kubectl create -f deploy/kube-config/influxdb/
  kubectl create -f deploy/kube-config/rbac/heapster-rbac.yaml
  </code></pre>
  
  <p>Any suggest?</p>
  
  <p><strong>Update</strong>:</p>
  
  <p>the command <code>kubectl top pod</code> works now but the endpoint doesn't work</p>
  
  <pre><code>kubectl get --raw "/apis/metrics.k8s.io/v1beta1/pods"
  #Error from server (ServiceUnavailable): the server is currently unable to handle the request
  </code></pre>
