This will build a demo environment of 3 boxes in Docker Swarm cluster and 2 Swarm Manager. It also configurers Conul so we can monitor the cluster and contianers on the cluster.
This is all automated and controlled with Puppet. It will also deploy Jenkins and Nginx. 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.
For example if jenkins was on swarm-103 you would access it from 127.0.0.1:8083 and nginx would be on 127.0.0.1:8003
consul
127.0.0.1:9501
Here are a few interesting commands to look at what is happening inside the swarm cluster. vagrant ssh into swarm-master-01
