+# Basic Arch Linux ARM Docker images [![Build Status](https://travis-ci.org/agners/archlinuxarm-docker.svg?branch=master)](https://travis-ci.org/agners/archlinuxarm-docker)
+
+Docker images for Arch Linux ARM on AArch32 (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.
+
+## Running the images
+
+The images are on [Docker Hub](https://hub.docker.com/u/agners/). Use the convenient `docker run`:
+
+    docker run --rm -ti agners/archlinuxarm
+
+Instead of using the multi-arch container above, you can also get the architecture specific image directly:
+
+    docker run --rm -ti agners/archlinuxarm-arm32v7

+
+### 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.
+
+## Issues and improvements
+
+If you want to contribute, get to the [issues-section of this repository](https://github.com/agners/archlinuxarm-docker/issues).
+
+## Common hurdles
+
+### Setting the timezone
+
+Simply add the `TZ` environment-variable and define it with a valid timezone-value.
+
+```
+docker run -e TZ=Europe/Berlin agners/archlinuxarm
+```
+
+## 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=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 arise is how this all
+started. The initial containers have been created using the tarballs provided by
+the Arch Linux ARM project. 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 agners/armv7-archlinux:latest
+```
+
+## Credits
+
+Ideas have been taken from already existing Docker files for Arch Linux.
+However, this repository takes a slightly different approach to create images.
+
+- https://github.com/archlinux/archlinux-docker
+  - Focus on Arch Linux for x86
+  - Uses docker run in priviledged mode to build images
+- https://github.com/lopsided98/archlinux
+  - Uses prebuilt tarballs which contain packages not required in containers
