How to properly restart containers? #59

I installed sequenceiq/ambari:1.7.0 on Vagrant with Ubuntu and run cluster with 3 nodes. They were working fine and all services too. IPs of these nodes are 172.17.0.2...4 But I stopped containers and tried to restart using docker start amb0 amb1 amb2. Now Ambari is not see any of nodes because they are having other IPs. I think that would be better if cluster will work with any IPs of nodes

How to restart nodes properly and where is config for that hardcoded IP

Looks like Docker is working on being able to retain static ips: http://blog.docker.com/2015/04/docker-networking-takes-a-step-in-the-right-direction-2/#more-5307

Someone wrote a patch in the mean time: https://github.com/pdumais/docker

There is no proper way to restart, yet. We'll make the Consul based Ambari feasible for local environments where we won't rely on IP addresses.
