Mainly I don't want the overhead of building and managing container images at all. My apps all run the same way, I have a fleet of servers that are set up to run them, something that can manage distributing apps onto servers and routing with load balancers etc. would be cool just without the docker/container piece. This was a main selling point for Nomad so I'm pretty sure there's no way to run k8s to do that, or at least it's not supported/first-class.
