+- Small disclaimer: the original playbook was tested for Debian, Ubuntu and Rocky. I use Ubuntu 24.04 / 26.04 usually, but it works with Rocky 10, Alma 10 and Debian 13. If you're using (minimal) cloud-init style images for Rocky 10 and Alma 10 you'll need to install extra kernel modules; you can do so by running `sudo dnf install -y kernel-modules kernel-modules-extra` followed by `sudo reboot` and `sudo modprobe br_netfilter` before running the whole playbook. More about that can be found on [this page](https://forums.rockylinux.org/t/docker-installation-failed-on-rhel-10/20024).
