dockersh - A shell which places users into individual docker containers

A user shell for isolated, containerized environments. dockersh is designed to be used as a login shell on machines with multiple interactive users. When a user invokes dockersh, it will bring up a Docker container (if not already running), and then spawn a new interactive shell in the container's namespace.
ou want to allow multiple users to ssh onto a single box, but you'd like some isolation between those users. With dockersh each user enters their own individual docker container (acting like a lightweight virtual machine), with their home directory mounted from the host system (so that user data is persistent between container restarts), but with its own kernel namespaces for processes and networking.
This means that the user is isolated from the rest of the system, and they can only see their own processes, and have their own network stack. This gives better privacy between users, and can also be used for more easily separating each user's processes from the rest of the system with per user constraints.
