In Docker, the hub runs in the `worker` container, which publishes 1883 and 5514; set `LENS_MQTT_PORT` or
`LENS_SYSLOG_PORT` when something else on the machine has those ports. Run natively, it runs in `lens worker` (and in
`LENS_SYSLOG_PORT` when something else on the machine has those ports. The development compose file
(`docker-compose.yml`) publishes them on this machine only; set `LENS_SENSOR_BIND=0.0.0.0` to let devices on the
network reach them. Run natively, it runs in `lens worker` (and in
the API when it runs background work). Several processes can run it: the first to get the port serves it, and the
others try again every minute.
