We want to develop a small Django webapp that allows users to view our pizza menu. We have started to build a locally running app, and we want to run it inside a Docker container so that we can deploy it to our Kubernetes cluster.
- For this project we will be using Django and Docker.
- Because of the time limit, it is NOT important to have a fully functional application at the end.
- Your interviewer is your pair! Be sure to ask questions and talk through your thoughts.
- First, let's assume we have the following web app running locally.
- On our webpage, we will display each pizza and its ingredients. The app is backed by a SQLite database (
pizza_app/db.sqlite3) with fixture data to be loaded frompizza_app/pizza_data.json. - In the project directory, you can run
python manage.pyto see a list of available Django management commands. Django management commmands can be used to do things like:- Run database migrations:
manage.py migrate - Load fixture data into the database:
manage.py loaddata pizza_data.json
- Run database migrations:
- Run
python manage.py runserverto start the app in developer mode, and visit in the browser at: http://localhost:8000/pizza/
-
Let's get our app running in a Docker container. You will find a stubbed-out Dockerfile and docker-compose.yaml we will use to run the service. There might be a bug or two in there!
-
Once we have the Dockerized app running, let's discuss the stubbed out yaml file in the
kubernetes/directory.
