Docker compose cluster simulating IoT network with edge devices communicating via MQTT protocol. Includes Node-RED and Node-RED dashboard.
- slim containers
- mosquitto broker
- Node-RED with dashboard
To start a cluster with 3 edge devices: docker-compose up -d --build --scale edge=3
This will expose the following ports:
- Node-RED: 1880 (add /ui for dashboard)
- MQTT broker: 1883 (for use with mqtt-spy and a like)
Open Node Red dashboard on localhost:1880. Import the following snippet as clipboard to create a sample chart. Deploy and open localhost:1880/ui.
