Off the top of my head? Namespaces, base images, configMaps (this should be pretty obvious), monitoring.
Now all of this can be done, but Kubernetes does this thing where it talks extensively about applications and then goes "oh so anyway, um, like, I guess just put that stuff in git?"
Which you can but with what separation? The way my configuration mounts to my applications is probably somewhat application determined, but "where" stuff runs is infrastructure.
None of it matters because K8S doesn't have an answer for any of it: no standard for emitting state from clusters to allow self-configuration, no system to define axes of freedom in configuration shape, no well defined system for say, plugging your applications network requirements into perhaps a clusters policy of what networking should be. No way to expose a set of permissions for reconfiguring my infrastructure to the cluster so RBAC can define a sensible ops model.
K8S is essentially a platform-for-platforms which is why it feels complicated: the moment you have it setup, you realize just how much is actually missing if you try to use it like it bills itself as.
