A cargo subcommand to build Rust code inside docker and get the result back.

It's useful to build binary with other environment. As example, you can build binary for CentOS inside Ubuntu.

To use cargo-docker you should type the following:

$ cargo docker --image=rustup/debian:jessie --output=jessie-target

This command uses docker without sudo and you have to get rights to use docker.

Add docker group:

$ sudo groupadd docker
$ sudo service docker restart

Not necessary if you have installed new version of docker.

Add yourself to docker group:

$ sudo gpasswd -a ${USER} docker

Login again to update user flags.
