Update BDC Tracker deployment

[amc-corey-cox]

I have uploaded the new image for deployment to docker.io. Looks like things work fine. We could use a little documentation of the process.

Here is the current location: https://hub.docker.com/repository/docker/coreyamc/bdc_tracker_app/general (Private Repository)

This is how to share the container:

docker login -u <your-dockerhub-username> -p <token> docker.io
docker pull <your-dockerhub-username>/<repository>:<tag>

Tokens can be created (and deleted) here:

https://hub.docker.com/settings/security (login required)

We are deploying to an AWS EC2 instance. First, I'll want to document the process. Then, we'll see if we can automate some of this using GitHub actions.
