Personally, I've found Chef Habitat to be a sane alternative. I don't have any experience with k8s, but if you are not using containers especially, Habitat gets you: - packaging - deploys - configuration management - supervision - service discovery - isolation in a more classic "VM" environment, using unix jails. For anyone who isn't interested in learning k8s, but also wants a relatively modern, all-in-one solution to these problems, I recommend checking it out.
