Kubernetes is an operating system. Using it to run your software is as overkill today as running your own Linux server was overkill before that. Maybe you just need to run on Heroku and don't need the complexity of writing systemd service files? In the end, the steps you take to deploy with rsync and run your systemd service are the same (conceptually) you'd take to run on K8S, but translated to some YAML and a docker push. In one case you need to learn a new paradigm, in the other case you deal with something you already know. Not having to learn something new is an argument, but it doesn't mean your bare-Linux approach is simpler than the K8S approach. You just know it more.
