Make docker containers stateless
As a first order of importance, persistent data should be located outside of application containers and located either on a host disk or in a designated storage container in Docker. Secondly, containers should operate without using Puppet. Last minute deployment parameters should come from environmental variables or be managed outside of the container and mounted (such as /etc/nailgun)
