Base Image Creation
|
|
|
|
|
===================
|
|
|
|
|
|
|
|
|
|
So you want to create your own :ref:`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
|
|
|
|
|
<https://wiki.debian.org/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
