Configuring Couchbase Server 4.0 Beta

Question

I have configured Couchbase Server 4.0 Beta on four instances of AWS EC2. I have set up two instances to have data service running and one each for index and query service. [Multi Dimensional Scaling Now, when i set the cluster up, I set the hostname of each server as my public DNS, so that the servers can find each other across data centers. Everything works fine, till I shut my instances down.

When i start my instances again, couchbase servers don't start. I'm assuming this happens becaues my public DNS changes everytime I restart the server. This forces me to re-install couchbase every time i shut my instances down, and repeat the entire process of configuration again. I'm sure there must be an easy (and much better) alternative to this. Is there any way I can configure the hostname, and the hostname of all the servers in my cluster before starting any server?

You need to ensure that when you initialise your cluster node you use hostnames, not IP addresses to identify nodes. See Couchbase in the Cloud section in the admin guide for more details.
