  -d, --dry-run         Run in dry-run mode, do not ingest data
  -o DRY_RUN_OUTPUT_DIR, --dry-run-output-dir DRY_RUN_OUTPUT_DIR
                        Output dir for dry-run mode. Environment variable can be used by wrapping it in ${} (e.g. ${OUTPUT_DIR})
  --otel-endpoint OTEL_ENDPOINT
                        OpenTelemetry exporter endpoint
  --otel-export-period OTEL_EXPORT_PERIOD
                        Period in seconds between OpenTelemetry exports (default: 60)

Run worker

worker can be run by installing it with pip

git clone https://github.com/netboxlabs/orb-agent.git
cd orb-agent/orb-discovery/
pip install --no-cache-dir ./worker/
orb-worker -t 'grpc://192.168.0.10:8080/diode' -c '${DIODE_CLIENT_ID}' -k '${DIODE_CLIENT_SECRET}'

Docker Image

worker is built from source into the netboxlabs/orb-agent image (from orb-discovery/worker in this repo); there is no standalone worker image. Run it via the agent image, which launches the backend on demand, or use orb-test-lab for local testing.
