Arch Linux Builder

Using Arch Linux as a base image for another Docker image is useful, since Arch has a large variety of packages, mostly in their most recent versions. However, sometimes you also have to install packages from AUR. In order to do that inside Docker you have to:

1. Install base-devel and sudo
2. Configure sudo to allow nobody to execute anything without requiring a password
3. Download and install cower manually
4. Download and install Pacuar manually
5. Set up a home directory for nobody
6. Execute Pacaur as Nobody

Doing so will add more code into your Dockerfile as well as make the size of the final image much larger than needed.

You can avoid all of that by taking advantage of Docker's multi-stage builds together with this image:

FROM darwish/archlinux-builder AS build
RUN pacaur -am rpm-org dpkg

FROM archlinux/base
COPY --from=build /home/nobody/build/*.pkg.tar.xz /tmp/
RUN pacman -Sy && pacman -U --noconfirm /tmp/*.pkg.tar.xz
RUN rpm --version
RUN dpkg --version

The final is derived from the official Arch Linux image and does not contain any build dependencies.
