docker-cowbuilder's Introduction

Cowbuilder in Docker

The copy-on-write chroot build tool for Debian.

Usage

Pull the image from Docker Hub

docker pull lazyfrosch/cowbuilder

Have a look on the helper script cowbuilder.example.sh here and modify it to your needs.

vim cowbuilder.example.sh
cp cowbuilder.example.sh $HOME/bin/cowbuilder
chmod +x $HOME/bin/cowbuilder

Then you can run cowbuilder like it would be installed locally.

In addition the cowbuilder script starts cowbuilder-auto, which will take care of creating and updating the base chroots.

cowbuilder login --distribution stretch
# will create / update and give you a prompt inside

Install helper scripts

cp cowbuilder-helper.example.sh ~/bin/cowbuilder-helper
edit ~/bin/cowbuilder-helper  # to your needs
cd ~/bin/
ln -svf cowbuilder-helper cowbuilder
ln -svf cowbuilder-helper cowbuilder-auto
ln -svf cowbuilder-helper uscan
ln -svf cowbuilder-helper dpkg-source

Important notes

About the helper script.

For correct permissions to work the helper script uses your UID and GID to write files
The helper script mounts your HOME directory to the container
Put the cache volume to a persistent location on your host
