debootstrap is a very powerful tool that most of debian/ubuntu people already know about.
It’s really super easy to create your own basic debian docker image, even if you are not running debian.
I used the below steps to my archlinux box, but i believe are generic and you can also use them, without any effort.
Step One:
Download and prepare debootstrap
# wget -c http://ftp.debian.org/debian/pool/main/d/debootstrap/debootstrap_1.0.77.tar.gz
# tar xf debootstrap_*.tar.gz
# cd debootstrap
# sed -i -e 's#/usr/share/debootstrap#.#' debootstrap
Step Two:
debootstrap a new sid (unstable) debian:
# mkdir sid
# ./debootstrap --arch amd64 --include=aptitude sid sid/
Step Three:
Just to be safe, extract debian packages with ar
# cd sid
# for i in `ls -1 var/cache/apt/archives/*deb`; do ar p $i data.tar.xz | tar xJ ; done
# for i in `ls -1 var/cache/apt/archives/*deb`; do ar p $i data.tar.gz | tar xz ; done
# rm -rf var/cache/apt/archives/*deb
Step Four:
Prepare your debian unstable directory.
eg. create the sources.list file
# cat > etc/apt/sources.list << EOF
> deb http://ftp.gr.debian.org/debian unstable main contrib non-free
> deb http://ftp.debian.org/debian/ Sid-updates main contrib non-free
> deb http://security.debian.org/ Sid/updates main contrib non-free
> EOF
Step Five:
Dockerized your debian image:
# tar -c . | docker import - debian:sid
cdf6f22b76f23fa95ae2d5858cec4546086a2064b66cf34b937bc87c83f13c91
# docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
debian sid cdf6f22b76f2 5 seconds ago 291.3 MB
You are now ready to play with your new image:
# docker run -t -i --rm debian:sid bash
