title: How to implement Kubernetes POD to POD Communication?
body: <p>This question has been asked and answered before on stackoverflow but because I'm new to K8, I don't understand the answer.</p>
  
  <p>Assuming I have two containers with each container in a separate POD (because I believe this is the recommend approach), I think I need to create a single service for my two pods to be apart of.</p>
  
  <ol>
  <li>How does my java application code get the IP address of the service?</li>
  <li>How does my java application code get the IP addresses of another POD/container (from the service)?</li>
  <li>This will be a list of IP address because these are stateless and they might be replicated. Is this correct?</li>
  <li>How do I select the least busy instance of the POD to communicate with?</li>
  </ol>
  
  <p>Thanks
