- Welcome to my pizza app.
- This app simulating pizza restaurant that has a specific workflow:
- Fist, the order is receives, the app assign the order id if it doesn't supply.
- Then the dough chef making the perfect dough for the pizza. (with sugar spice and every day nice)
- when the dough is ready, toppings chef work had to put toppings on the pizza.
- After the toppings is sets, its time to cook, the oven run in action.
- bling, bling! pizza is ready and the waiters need to serve it ASAP.
- each phase takes a different amount of time:
- dough - 7 seconds
- toppings - 4 seconds for each topping
- oven - 10 seconds
- waiter serves - 5 seconds
- restaurant has a limited resources
- 2 Dough chefs
- 3 Toppings chef (that each can place 2 toppings)
- 1 Oven
- 2 Waiters
- each pizza order produces reports of its time of preparation.
- each bulk of orders produces report of the total time of the pizzas preparation.
- report is save on database.
- the app uses
asyncio python build in module.
- the application uses producer/consumer pattern to process the orders.
- each of the restaurants employee's role has a queue/s, the queue/s is for consuming orders and producing orders to the
next phase.
- there are certain roles in the system, for example:
- bulk_producer - which produce all of the incoming orders in bulk
- dough_chef_consumer - the fist step, consumes pizza and make its work
- dough_chef_producer - after it done produce the next step (which is topping chef)
python main.py with pre-defined data samples:
- read the following and pass to "execute" section
- make sure to un-comment the two last lines in
main.py file
from data_samples import order_doc
restaurant.post_orders(order_doc)
- make sure to comment the following line in
main.py file
# app.run(host="0.0.0.0", port=5000, debug=True)
- read the following and pass to "execute" section
- make sure to un-comment the two last lines in
main.py file
# from data_samples import order_doc
# restaurant.post_orders(order_doc)
- make sure to comment the following line in
main.py file
app.run(host="0.0.0.0", port=5000, debug=True)

- there is not any validation to requests body, make sure to send data correctly to avoid 500 error
- the
id field is not required
- the
toppings field is required but can be empty list.
- Look for the file
docker-compose.yml that is located in the root directory of the repository.
- Open the
yaml file and check if your port is not already allocated to other applications
- If so, you need to change port or close running apps on this port.
- Run the command
docker-compose up -d - the app will start run immediately.
- To be able to see the logs run
docker logs pizza_assignment-pizza-app-1
Inspect data in MongoDB container
- Connect to docker bash - run
docker exec -it pizza_assignment-mongodb-1 bash
- Once inside the container, start the MongoDB shell by running the mongo command:
mongosh
- switch to use
pizza_app context run use pizza_app
- To view the data in a specific collection, you can use the
db.pizza_reports.find().pretty() command.
- There you go :)
- Run
docker-compose down in root directory of the repository
