docker-arch-build

This is a base image for building packages for Arch Linux.

Purpose

This docker image builds on top of Arch Linux's base/devel image for the purpose of building arch packages. It provides several key features:

• A non-root user (build) for executing the image build. This is important to ensure that the package can be built correctly without destructively modifying the system.
• The pkgbuild-introspection library including the mksrcinfo and mkaurball commands. This makes it easy to generate the .SRCINFO files to upload to AUR for your packages.
• The namcap command is included to help validate your PKGBUILD's.
• Default docker command of makepkg --force. This is a common usecase: needing to build the package for testing.
• Access to the build location will be in the volume located at /package.

Usage

This library is useful with simple PKGBUILD's from the command line. For example, assuming you have a PKGBUILD with no additional dependencies beyond base-devel in /tmp/my-package:

docker run --interactive --tty --rm --volume /tmp/my-package:/package nubs/arch-build

# Using short-options:
# docker run -i -t --rm -v /tmp/my-package:/package nubs/arch-build

This will make the package placing the results (including the pkg.tar.xz file for a successful build) in /tmp/my-package.

In order to create the .SRCINFO:

docker run -i -t --rm -v /tmp/my-package:/package nubs/arch-build mksrcinfo

Dockerfile build

Alternatively, you can create your own Dockerfile that builds on top of this image. This allows you to modify the environment by installing additional software needed, altering the commands to run, etc.

A simple one that just installs another package but leaves the rest of the process alone could look like this:

FROM nubs/arch-build

USER root

RUN pacman --sync --noconfirm --noprogressbar --quiet php

USER build

You can then build this docker image and run it against your PKGBUILD volume like normal (this example assumes the PKGBUILD and Dockerfile are in your current directory):

docker build --tag my-package .
docker run -i -t --rm -v "$(pwd):/package" my-package
docker run -i -t --rm -v "$(pwd):/package" my-package mksrcinfo

Permissions

Because the container runs as a non-root user, you may run into permission problems when using volume mounts to your host. The build user used in the container is uid/gid 1000, so you may need to provide write access to that user to any files/directories that need to be written to. For example:

chgrp 1000 .
chmod g+w .
