In this case, we may install Postgres locally, we can set the application to connect to a remote database provided as a service, or we can spin up a new container running a Postgres database.

Because we don't care about the data that we'll temporarily store, it can be deleted as soon as the container stops.
The next steps now could be writing the Dockerfile for the database container and then creating the Docker network plumbing to connect ...
