4. (Optional) Set MySQL Password, MySQL Root Password

5. Install Docker and start docker daemon

6. Host MySQL server on Docker container and expose it to the port 3306. Use commands -
   (Ensure you are in the project home directory)
   Build - docker build -f docker/db/Dockerfile -t pizzeria_db .
   Run - docker run --network=host -it --expose 3306 -p 3306:3306 pizzeria_db

   Build - docker build -f docker/apis/Dockerfile -t pizzeria_apis_tasks .
   Run - docker run --network=host -it --expose 8000 -p 8000:8000 pizzeria_apis_tasks
   

9. Open Docker Desktop and run a terminal in pizzeria_apis_tasks container
   OR
   docker images | grep pizzeria_apis_tasks # Copy id
   docker run -i -t /bin/bash
   

10. Run migrations and run the server:
    python manage.py makemigrations
    python manage.py migrate
    python manage.py runserver 8000
    

11. Similary open another terminal to run process_tasks (background tasks):
