Step 4 - Build with Docker
==========================
Now that we have our code properly built/compiled, we can create a Dockerfile. This file defines how to build the Docker image for the service by declaring the environment, building stages, and copying any binaries or assets needed to run the service to the Docker image filesystem.

In other words, the Dockerfile serves as a recipe for creating a Docker image, from which Docker containers are spun up. This is ultimately what runs an instance of your service on the Embassy.

This is a script that defines how the service starts, and often acts as an init system. It will need to complete any environment setup (such as folder substructure), set any environment variables, and execute the run command. It's also PID 1 in the Docker container, so should do all of the signal handling for container exits.
