Install dependencies

Install python3-venv package

$ sudo apt install python3-venv python3-dev libsdl-dev libsdl-image1.2-dev libsdl-mixer1.2-dev libsdl-ttf2.0-dev

For shapely

$ sudo apt install libgeos-dev

Create a virtual environment for python3

$ python3 -m venv .venv

Install requirements from the file

$ source .venv/bin/activate
(.venv)$ pip3 install wheel
(.venv)$ pip3 install -r requirements.txt

Check shapely speedups:

>>> from shapely import speedups
>>> speedups.enabled

Message Broker

Install the message broker locally:

$ sudo apt install mosquitto mosquitto-clients

or run it inside a Docker container:

$ cd docker
$ docker build -t mqtt-broker .

$ docker run -p 1883:1883 -t mqtt-broker

List the installed Docker images with docker image ls or docker system df in either case sometimes it's necessary to reset the environment: docker system prune

Tagging the Docker image after building: docker tag 3b6b527f221b mqtt-broker
