This will build a demo environment of 3 boxes in Docker Swarm cluster and 2 Swarm Masters. It also configurers Conul so we can monitor the cluster and contianers on the cluster. This is all automated and controlled with Puppet. The Swarm master will pick a node to deploy the contianers on. So you can check the consul gui, ping the service name from any of the 5 boxes or logon to one of the swarm masters and run docker -H tcp://172.17.8.114:2376 ps. Once you have the ip of the box, you can access the app on the forwarded port from the server.yaml.

#Update The demo now builds a fuly operational ELK stack https://www.elastic.co/ You can find where all the containers are scheduled through the Consul ui It also adds enhanced checks to Consul to monitor the Swam-masters.
