To run this:
docker run -p 80:80 -it -h jockey.local cloudbees/joc-trial
Then ensure jockey.local resolves to your docker container IP (boot2docker ip will tell you that).
Once you have a licence setup - you can stop the container - use docker ps to look up its name (or use --name to give it a funny name) - and then docker start it in future as needed for demos (or start fresh each time). Mapping in other ports -p 8000 (HA proxy) and 8080, 9090 for direct JOC and Jenkins ports may also be fun to do.
