title: Does Kubernetes support connection draining?
body: <p>Does Kubernetes support connection draining?</p>
  
  <p>For example, my deployment rolls out a new version of my web app container. 
  In connection draining mode Kubernetes should spin up a new container from the new image and route all new traffic coming to my service to this new instance. The old instance should remain alive long enough to send a response for existing connections.</p>
