title: What is the best way to rename okd cluster's master?
body: <p>We are running a cluster "<em>Single master and multiple nodes</em>" (in <a href="https://docs.okd.io/latest/install/index.html#multi-masters-using-native-ha-colocated" rel="nofollow noreferrer">https://docs.okd.io/latest/install/index.html#multi-masters-using-native-ha-colocated</a>). Let's call our servers oomaster1, oonode1 and oonode2.</p>
  
  <p>I would like to add other masters one day and I think the first step would be to add a VIP oomaster, now pointing only to oomaster1, and then rename the cluster (currently oomaster1) to oomaster.</p>
  
  <p>What would be the best way to proceed ? I mean I can just stop all okd related services and replace oomaster1 (and its address) with oomaster (and its address) in every file in /etc/origin and /etc/etcd and then restart services. But I suppose it is more complex...</p>
  
  <p>Thanks in advance for advices</p>
