Create Docker Containers for Backend and DB

[KentTran2302]

What does this PR do?

• Dockerize backend development environment
• Add debugpy debugger

Pre-requisites

Install Docker Desktop: [(https://www.docker.com/products/docker-desktop/)]

How should this be tested?

Setup

Ensure you have Docker Desktop installed and opened. Then run

docker compose up -d --build

This is a sample .env file you can use to test:

DB_HOST = "martinrea_db"
DB_USER = "<your-db-username>"
DB_PASS = "<your-db-password>"
DB_PORT = 5432
DB_NAME = "martinrea"
FLASK_ENV = development

MONGO_DB_USERNAME = "<your-mongo-db-atlas-username>"
MONGO_DB_PASSWORD ="<your-mongo-db-atlas-password"

Note the DB_PORT environment variable, do not use PORT since deployment service like Fly.io will set a PORT environment variable for the deployed server

• Please note that you can either use MySQL, PostgreSQL or SQLite to store the data but don't forget to change the URI and the engine connection to the database on your local machine.

• One more thing, this doesn't work yet since there are some conflict in the dependencies, I will take a closer look when I have time to solve this dependencies in the Pipfile and Pipfile.lock.
