Steps

  1. create coturn directory in $HOME/podman
    mkdir -p ~/podman/coturn && cd ~/podman/coturn
  2. copy from compose.yml
    nano compose.yml
  3. copy from turn_with_password.conf
    nano turn_with_password.conf
  4. copy from turn_with_secret.conf
    nano turn_with_secret.conf
  5. start coturn
    podman-compose -f ~/podman/coturn/compose.yml systemd -a register
systemctl --user enable --now podman-compose@coturn
