I think a good course would be setting up a k8s cluster for a simple "hello world" production app, which then includes topics perhaps about monitoring, upgrading, etc all the kind of stuff you want to know for getting an app up and running.
As a bonus, show how to use Gitlab for deploying and managing the app. Gitlab + Kubernetes could be the holy grail for modern, self-hosted development, however a good, complete tutorial/documentation is very hard to come by. One has to pick the pieces from a lot of different places with sometimes conflicting information.
I'd happily pay 100 Euros for such a course.
