aurantium

Aurantium

Aurantium's goal is to be an MQTT publisher. The steps to publish data are as follows:

• On startup, connect to the MQTT broker.
• Read files one by one from a given folder path.
• In each contained file, read the data line by line skipping the first line (contains column names).
• For each line read, create a Machine object and schedule a Publish message to the MQTT broker.

Maven Build

Run from the root directory of the project to build the .jar file.

mvn clean install -DskipTests -f aurantium/pom.xml

Note: Depends on Protobuf module. Consider building it first.

Local Run

To run locally, you need to have a Mosquitto broker up and running and then run Aurantium.

Mosquitto Broker

1. Create a .conf file with some simple configuration: echo -e 'listener 1883 \nallow_anonymous true' >> mosquitto.conf.
2. Install and run the broker:
   1. Install it locally with apt install mosquitto. Run it with mosquitto -c {FULL_PATH_OF_CONF_FILE}. Or,
   2. Use a Docker image. Pull it with docker pull eclipse-mosquitto:2.0.11. Run it with docker run -it -p 1883:1883 -v {FULL_PATH_OF_CONF_FILE}:/mosquitto/config/mosquitto.conf eclipse-mosquitto:2.0.11.

Aurantium

Run AurantiumApplication.java with the following env variables:

1. filePath={FULL_PARENT_PATH}/citrus/aurantium/src/main/resources/iot-data/machine
2. machine.id=0
3. mqtt.host=127.0.0.1
4. mqtt.port=1883
5. publish.delay=1

Docker Build

Run from the root directory of the project to build the Docker image. Consider having a Mosquitto broker already up and running.

docker compose build aurantium

Docker Run

Run from the root directory of the project to run the Docker image(s).
