bugthing/docker-archlinux repository overview

⁠Docker image for Arch Linux

An Arch linux base image.

⁠Build

docker build -t docker-archlinux .

⁠How I built this image

Run the script that builds an Arch chroot, imports into a docker container.

$ sudo ./mkimage-arch.sh

The resulting output of the script includes the name of docker image. I used this to extract the filesystem Use docker to export/save the image:

$ docker save archlinux -o image.tar

Find the layer.tar file within the docker tar:

$ tar -tvf image.tar | grep layer.tar

Pull that layer.tar out of the image.tar (see result of prev. command)

$ tar --extract --file=image.tar c5f3671366de897b9fa72099232f89be3be528d32f5648a88a8768870e291310/layer.tar

Rename and compress:

$ mv c5f3671366de897b9fa72099232f89be3be528d32f5648a88a8768870e291310/layer.tar ./arch-$(date +%F).tar
$ xz ./arch-*.tar

Update the Dockfile to ADD the newer arch base system

Commit the updated files to the git repo.

I orginally got the mkimage-arch.sh from here⁠ and the downloaded mkimage-arch.sh and mkimage-arch-pacman.conf, like so:

$ wget https://raw.githubusercontent.com/docker/docker/master/contrib/mkimage-arch-pacman.conf
$ wget https://raw.githubusercontent.com/docker/docker/master/contrib/mkimage-arch.sh
$ chmod +x mkimage-arch.sh
