Basic Arch Linux Docker images Build Status

Docker images for Arch Linux on x86_64, AArch32 (ARMv6-A, ARMv7-A) and AArch64 (ARMv8-A). Built using native pacman and Docker multi-stage builds. Builds weekly by Travis CI on publicly visible infrastructure using QEMU emulation to support ARM.

Tags

Tag Update Type Description
yay daily base-devel + yay + sudo Arch Linux with base-devel, sudo and yay aur helper installed. Contains a default user called user too with sudo access without password

Latest is with the architecture, and if not specified, it will download the correct minimal for the architecture you're running Docker from.

To get specifc architecture images, you need to use the following format samip537/archlinux:$ARCH-$TAG.

Eg:

docker run --rm -ti samip537/archlinux:arm32v7-yay

Layer structure

The image is generated from a freshly built pacman rootfs. Pacman has configured to delete man pages and clean the package cache after installation to keep images small.

Common hurdles

Setting the timezone

Simply add the TZ environment-variable and define it with a valid timezone-value.

docker run -e TZ=Europe/Helsinki samip537/archlinux

Building it yourself

Prerequisites

  • Docker with experimental mode on (required for squash)
  • sudo or root is neccessary to setup binfmt for Qemu user mode emulation

Building

  • Prepare binfmt use with Qemu user mode using sudo ./prepare-qemu
  • Run BUILD_ARCH=<arch> ./build to build
    • Use BUILD_ARCH=amd64 for x86_64
    • Use BUILD_ARCH=arm32v7 for ARMv7 Aarch32
    • Use BUILD_ARCH=arm64v8 for ARMv8 Aarch64

If you want to push the images, run ./push. But be aware you have no push access to the repos! Edit the scripts to push to custom Docker Hub locations!

Building from scratch

Since the image depends on itself, the question which arises is how this all started. The initial containers have been created using the tarballs provided by the Arch Linux ARM project.

ARMv6 is based off the image for Raspberry Pi 1, which may or may not work on other hardware.

I used the following steps to bootstrap for each architecture:

sudo tar xvzf ArchLinuxARM-armv7-latest.tar.gz -C tmp-arch
sudo tar cf ArchLinuxARM-armv7-latest.tar -C tmp-arch/ .
docker import ArchLinuxARM-armv7-latest.tar samip537/archlinux:arm32v7

Credits

Ideas have been taken from already existing Docker files for Arch Linux. However, this repository takes a slightly different approach to create images.
