deber

Debian + Docker = Deber

Utility made with simplicity in mind to provide an easy way for building Debian packages in Docker containers.

Screencast

Features

• Build packages for Debian and Ubuntu
• Use official Debian and Ubuntu images from DockerHub
• Automatically determine if target distribution is Ubuntu or Debian by querying DockerHub API
• Skip already ran steps (not every one)
• Install extra local packages in container
• Plays nice with gbp-buildpackage
• Easy local package dependency resolve
• Don't clutter your parent directories with .deb, .dsc and company
• Every successfully built package goes to local repo automatically so you can easily build another package that depends on previous one
• Ability to provide custom dpkg-buildpackage and lintian options
• Packages downloaded by apt are stored in temporary directory, to avoid repetitive unnecessary network load
• Option to drop into interactive bash shell session in container, for debugging or other purposes
• Use network in build process or not
• Automatically rebuilds image if old enough

Installation

Source (latest master)

go install github.com/dpvpro/deber@latest

Usage

I recommend to use deber with gbp if possible, but it will work just fine as a standalone builder, like sbuild or pbuilder.

Let's assume that you are in directory with already debianized source, have orig upstream tarball in parent directory and you want to build a package. Just run:

deber

or if you use gbp and have builder = deber in gbp.conf

gbp buildpackage

If you run it first time, it will build Docker image and then proceed to build your package.

To make use of packages from archive to build another package, specify desired directories with built artifacts and deber will take them to consideration when installing dependencies:

deber -p ~/deber/unstable/pkg1/1.0.0-1 -p ~/deber/unstable/pkg2/2.0.0-2

FAQ

Ok, everything went well, but... where is my .deb?!

The location for all build outputs defaults to $TMP/deber/packages.

Where is build directory located?

$TMP/deber/builddir/$CONTAINER

Where is apt's cache directory located?

$TMP/deber/cachedir/$IMAGE

How images built by deber are named?

deber:$DIST

I have already built image but it is building again?!

Probably because it is 14 days old and deber decided to update it.

How to build a package for different distributions?

Make a new entry with desired target distribution in debian/changelog and run deber.

Or specify the desired distribution with --distribution option.
