Learn the core fundamentals of Docker by building a Node/Express app with a Mongo & Redis database.

We'll start off by keeping things simple with a single container, and gradually add more complexity to our app by integrating a Mongo container, and then finally adding in a redis database for authentication.

We'll learn how to do things manually with the cli, then move on to docker compose. We'll focus on the challenges of moving from a development environment to a production environment.

We'll deploy and Ubuntu VM as our production server, and utilize a container orchestrator like docker swarm to handle rolling updates.
