You may use Debian images from [[https://index.docker.io/_/debian/|Docker.io's Debian official repository]] if you trust their author, or you may prefer to create them yourself, using the methods described below.

Note that due to bug #740855 `/usr/share/docker.io/contrib/mkimage-debootstrap.sh` needs to be patched at the moment. The `docker.io` package ships the `/usr/share/docker.io/contrib/mkimage-debootstrap.sh` script which may be used to create a Docker image for Debian (or Ubuntu) using `debootstrap`, and with or without further tweaks.

You may create an image with : ''Note that due to bug DebianBug:740855 `/usr/share/docker.io/contrib/mkimage-debootstrap.sh` needs to be patched at the moment.''

You may create an image for the `stable` suite (using the `minbase` debootstrap variant) with :

.../mkimage-debootstrap.sh $USER/debian sid .../mkimage-debootstrap.sh $USER/minbase stable
Line 16: Line 18:
sudo docker.io run -i $USER/debian:sid echo "hello world" sudo docker.io run -i $USER/minbase:stable echo "hello world"
Line 18: Line 20:

As an alternative to upstream's choices, you may modify the script so that it does not use the minbase variant by default. See for instance [[https://raw.github.com/olberger/docker/debian/contrib/mkimage-debootstrap.sh|obergix's version]] and adjust to your needs.

See also http://www.debian-administration.org/article/696/A_brief_introduction_to_using_docker#a2 if you want to use a manual debootstrap install (without the upstream's contrib script's tweaks).


A dockerfile may then refer to your image using the following directive :
{{{
FROM YOURUSER/minbase:stable
}}}

You may test it with :
{{{
echo "FROM $USER/minbase:stable" | docker.io build -t $USER/test:stable -
}}}

This page attempts to document how to create a Debian image for Docker.

You may use Debian images from Docker.io's Debian official repository if you trust their author, or you may prefer to create them yourself, using the methods described below.

The following is work in progress WITHOUT ANY WARANTY

The docker.io package ships the /usr/share/docker.io/contrib/mkimage-debootstrap.sh script which may be used to create a Docker image for Debian (or Ubuntu) using debootstrap, and with or without further tweaks.

Note that due to bug 740855 /usr/share/docker.io/contrib/mkimage-debootstrap.sh needs to be patched at the moment.

You may create an image for the stable suite (using the minbase debootstrap variant) with :

.../mkimage-debootstrap.sh $USER/minbase stable

The image may then be used with :

sudo docker.io run -i $USER/minbase:stable echo "hello world"

As an alternative to upstream's choices, you may modify the script so that it does not use the minbase variant by default. See for instance obergix's version and adjust to your needs.
