These are kubernetes orchestration files (in the "kompose" directory) for the awesome course (highly recommended) that I bought here that teaches you how to write production grade microservices.

This course is highly recommended. Keep an eye out for future releases/upgrades to this course that will include new technologies including the possibility of orchestrations.
I can't recommend this course enough. The application he creates and walks you thru will run on both a Kubernetes Cluster and a Docker compose environment.
