Containerize the Server

[judtinzhang]

I am not too familiar with this, but the goal is to create a sufficient proof of concept that the project can be deployed.

This can be tested by creating a basic TCP socket on port 8000, and creating a working Dockerfile for the program.

Additionally, we also want a docker-compose file that spins up a local database for testing

To switch from a local database to production database, we will use an environment variable DATABASE_URL (in the docker-compose, DATABASE_URL will point to the local DB, in production, that variable will point to the production DB)

This should serve as sufficient proof of concept that the project can be deployed.
