By default, the flexFS metadata service starts a websocket server that listens on port 443 and uses a self-signed SSL certificate (which, for ease of configuration, mount clients are configured to accept).
📄️ Systemd
Though not required, it is advisable to use systemd to run the flexFS metadata server. Here is a functional sample service file:
