Set up Arch Linux (ARMv8) with Docker (homer dashboard, pihole, portainer...).

Arch updates are downloaded automatically, but have to be installed manually.

The script installs arch for Raspberry Pi 4 on the passed SD card:

$ cp .env.example .env
$ vim .env
$ setup_sd /dev/mmcblk0

SSH to the Pi and:

$ su
# ./arch_pi/install
# exit
$ ./arch_pi/install
$ sudo reboot

After reboot, set up Docker containers:

$ cd docker
$ ./update container_name
