MQTT Mosquitto
This project aims to create a middleware with mqtt using mosquito.
A client periodically publish some informations in a topic.
A secondary client listens for eventually new update in the previous topic.

$ docker run --rm -d \
-v "$(pwd)"/docker/mosquitto/config:/mosquitto/config \
-v "$(pwd)"/docker/mosquitto/log:/mosquitto/log \
-v "$(pwd)"/docker/mosquitto/data:/mosquitto/data \
-p 1883:1883 \

Before execute the main script, it's better to mock the gpio otherwise execution will fail.
export GPIOZERO_PIN_FACTORY=mock
Execute the following command to start the backend:
$ python main.py
Build push docker image
