Base Image Creation
So you want to create your own base_image_def? Great!
The specific process will depend heavily on the Linux distribution you want to package. We have some examples below, and you are encouraged to submit pull requests to contribute new ones.
Getting Started
In general, you'll want to start with a working machine that is running the distribution you'd like to package as a base image, though that is not required for some tools like Debian's Debootstrap, which you can also use to build Ubuntu images.
It can be as simple as this to create an Ubuntu base image:
$ sudo debootstrap raring raring > /dev/null
$ sudo tar -C raring -c . | sudo docker import - raring

$ sudo docker run raring cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=13.04
DISTRIB_CODENAME=raring
DISTRIB_DESCRIPTION="Ubuntu 13.04"There are more example scripts for creating base images in the Docker Github Repo:
