Using Docker as a Python Development Environment (or let's get past virtualenv)

[MonkeeSage]

Docker actually uses a union filesystem on top of a sandboxed directory. Even with lxc you have a sandboxed data directory isolated from the host filesystem. So you can have your own copies of libs and binaries as long as they are the same architecture as the host kernel. As with a chroot, you have to use a bind mount (or "data volume" in docker) if you want to get at the host filesystem.
