Implement Dockerfile and deployment pipeline

We need to deploy this service at some point so it would be cool to have a Dockerfile, as well as a deployment pipeline to deploy this service directly on Beep's infrastructure.
It should come with a documentation on how this service can be deployed.

The issue names no files, tests, or pipeline entry points. Start by inspecting the service's build and run configuration and Beep's infrastructure conventions; done means a working Dockerfile, an agreed deployment pipeline for Beep's infrastructure, and documentation covering deployment.
