A really simple IoT infrastructure project based on MQTT.

Project dependencies

• Node.js >= 12.8
• Docker >= 19.03.13
• docker-compose >= 1.27.4

Run example with docker-compose

1. Run the containers. This command will build them if they don't exist:

$ docker-compose up -d

Creating network "iot-infra_iot-network" with the default driver
Building broker
...
Successfully built blah blah
Successfully tagged iot-infra_broker:latest
WARNING: Image for service broker was built because it did not already exist. To rebuild this image you must use `docker-compose build` or `docker-compose up --build`.
Building monitor
...
Successfully built blah blah
Successfully tagged iot-infra_monitor:latest
WARNING: Image for service monitor was built because it did not already exist. To rebuild this image you must use `docker-compose build` or `docker-compose up --build`.
Building end_device

Successfully built blah blah
Successfully tagged iot-infra_end_device:latest
WARNING: Image for service end_device was built because it did not already exist. To rebuild this image you must use `docker-compose build` or `docker-compose up --build`.
Creating iot-broker ... done
Creating iot-monitor    ... done
Creating iot-end_device ... done

2. Check if they are up:

$ docker-compose ps

Name                   Command               State    Ports  
------------------------------------------------------------------
iot-broker       docker-entrypoint.sh node  ...   Up      1883/tcp
iot-end_device   docker-entrypoint.sh ./scr ...   Up      1883/tcp
iot-monitor      docker-entrypoint.sh ./scr ...   Up      1883/tcp

3. Print the logs:

$ docker-compose logs

Attaching to iot-monitor, iot-end_device, iot-broker
iot-broker    | Broker started and listening on port 1883
iot-end_device | MQTT client connected.
iot-end_device | MQTT client published message.
iot-monitor   | MQTT client connected!
iot-monitor   | Subscribed:
iot-monitor   |   topic: 'house/bedroom1/temperature'
iot-monitor   |   QoS:    1
iot-monitor   | house/bedroom1/temperature: 10.4

4. Bring them down if you want. Add -rmi to completely remove the images:

$ docker-compose down

Stopping iot-monitor    ... done
Stopping iot-end_device ... done
Stopping iot-broker     ... done
Removing iot-monitor    ... done
Removing iot-end_device ... done
Removing iot-broker     ... done
Removing network iot-infra_iot-network

Run example without Docker engine

1. Install depedencies:

$ npm --prefix broker install broker
$ npm --prefix monitor install monitor
$ npm --prefix end_device install end_device

2. Open a terminal. Run the server locally with:

$ cd broker
$ node index.js

Broker started and listening on port 1883

3. Open a new terminal. Run the monitor MQTT client.

 $ cd monitor
 $ node index.js

 MQTT client connected!
 Subscribed:
   topic: 'house/bedroom1/temperature'
   QoS:   1

4. Open a new terminal. Run the end-device MQTT client.

 $ cd end_device
 $ node index.js

 MQTT client connected.
 MQTT client published message.

5. Now in the terminal running the monitor client you can see the measurement:

house/bedroom1/temperature: 10.4

6. Terminate everything by pressing Ctrl+C.
