Consider a server with multiple IP Addresses, we create virtual machines, assign IP addresses to these machines, provide access to users etc.., most of the time the purpose of these virtual machines is to deploy applications eigther for testing or production. In the case of testing we aren't bothered about security or reliability of the host on which the application is running, so all that matters is time to setup testing environment, make backups, resetting the environment and so on. So in this scenerio running docker containers from images which has init system is a best substitute for virtual machines. docker-box is created to implement above use case using django for web interface and docker enginer api to manage docker. UI to run containers easily.
