Multiarch on docker/podman on linux (not desktop versions)

Enable

First install qemu-user-static package from your repository. For example, on debian/ubuntu:

apt update && apt -y install qemu-user-static

Next, enable emulation for binfmt on docker or podman:

sudo curl -o /root/qemu-binfmt-conf.sh https://raw.githubusercontent.com/qemu/qemu/master/scripts/qemu-binfmt-conf.sh
sudo find /proc/sys/fs/binfmt_misc -type f -name 'qemu-*' -exec sh -c 'echo -1 > {}' \;
sudo bash /root/qemu-binfmt-conf.sh --qemu-suffix "-static" --qemu-path /usr/bin -p yes

NOTE that the last 2 commands in the enablement section will have to be repeated on reboot to re-enable emulation.

NOTE that some distros may have the binfmt configuration tool as a package. Check with your OS documentation.

Usage

Simply switch your arch in aerolab with:

aerolab config backend -t docker -a arm64
...
aerolab config backend -t docker -a amd64
...
