Ensure that OpenVPN has been initialized and configured as described in the top level `README.md`.
Start the systemd service file:
Start the systemd service file specifying the volume container suffix as the instance. For example, `INSTANCE=test0` has a docker volume container named `ovpn-data-test0` and service will create `ovpn-test0` container:
systemctl start docker-openvpn
systemctl start docker-openvpn@test0
Verify logs if needed:
systemctl status docker-openvpn
docker logs openvpn0
systemctl status docker-openvpn@test0
