title: Communicate between pods in kubernetes
body: <p>I have something like this:</p>
  
  <pre><code>           POD-1
               |
   -------------------------
   ?|?        ?|?        ?|?
  service-1 service-2 service-3
  </code></pre>
  
  <p>How do I communicate from a server inside a pod, to other servers in pods behind services?</p>
