# 2022-09-29: './runrole --reinstall azuracast' is NOT supported!
#
# 1. But if you must, first completely uninstall Docker + WIPE AzuraCast data:
#
#    apt purge docker-ce docker-ce-cli containerd.io docker-compose-plugin docker-scan-plugin
#    rm -rf /library/docker /var/lib/docker /var/lib/containerd
#
#    Per https://docs.docker.com/engine/install/ubuntu/#uninstall-docker-engine
#
# 2. REBOOT to avoid later problems with 'systemctl status docker' -- if you
#    don't reboot, Ansible will fail below when 'docker.sh install' fails to
#    start docker.service -- likewise if you run './docker.sh install-docker'
#    manually in /opt/azuracast.  Either way, 'systemctl restart docker' won't
#    work for ~2 minutes.  (Rebooting avoids all these hassles!)
#
# 3. Just FYI the Docker install process will rebuild its 11 core directories
#    in /var/lib/docker -> /library/docker: (as 'docker.sh install' begins)
#
#    buildkit containers image network overlay2 plugins runtimes swarm tmp trust volumes
#
# 4. Just FYI both MySQL passwords (MYSQL_PASSWORD & MYSQL_ROOT_PASSWORD) will
#    be WIPED from /opt/azuracast/azuracast.env (and new passwords
#    auto-generated below, for use inside AzuraCast's Docker container).
#
# 5. Run './runrole --reinstall azuracast' in /opt/iiab/iiab
