# fluksio-worker Runs [Fluksio](https://fluksio.com) nodes on a machine the engine cannot reach — a GPU box, a cluster node, anything behind a NAT. It dials *out* to the engine over one authenticated websocket, so nothing has to be exposed here. ```sh pip install fluksio-worker fluksio-worker \ --url wss://api.example.com/api/v1/workers/attach \ --token "$FLUKSIO_WORKER_TOKEN" \ --labels gpu,cuda12 \ --python /opt/torch-venv/bin/python ``` `--python` is the interpreter node code runs on, which is how this machine keeps its own wheels without the engine ever installing them. Mint a token from the engine with `POST /api/v1/workers/tokens`. Linux and macOS.
