Chroot to Pi SD card on Arch Linux with Docker

chroot-to-pi-archlinux-docker.md

Installing qemu-user-static and binfmt-support from AUR have more trouble than it should on Arch Linux I opted on using Docker for using chroot-to-pi

Install and start docker

sudo pacman -S docker 

sudo systemctl start docker

Create a Dockerfile and use a recent Debian based distro as base

FROM debian:buster-slim
WORKDIR /work

Build and tag image

docker build -t kbeflo/chroot-to-pi .

Before continuing make sure you have already written the Raspberry Pi image to your SD card and already booted it at least once

Start the container

docker run -it --privileged -v /dev/bus/usb:/dev/bus/usb kbeflo/chroot-to-pi bash

Check if your sd card is present

fdisk -l

Install dependencies

Note: Except qemu, do not add these packages to the Dockerfile. They will not be installed properly on build

apt-get update

apt-get install -y wget qemu qemu-user-static binfmt-support

Get chroot-to-pi.sh

wget https://gist.githubusercontent.com/htruong/7df502fb60268eeee5bca21ef3e436eb/raw/e02726a023d57b29090dfb6485093d0f032db181/chroot-to-pi.sh

Set executable

chmod +x chroot-to-pi.sh

Start chroot-to-pi.sh

./chroot-to-pi.sh /dev/sdX

You can now continue as root or login as pi

su pi
