title: Reload nginx conf in kubernetes pods
body: <p>I have a kubernetes container running on GCE.<br>
  One of the service is nginx that working as proxy, and with replication controller it hass 10 replicas.<br>
  Now i need to change the nginx.conf for some tweaking.<br>
  Is there a way for me to reload all the nginx pods?  </p>
  
  <p>Right now the only way for me is scale it 0, then scale it up again to 10.<br>
  This will cause short downtime.</p>
