Cool! It looks like those are in beta/not very widely used though. And my impression is that I'd probably have to understand k8s/nomad pretty well to use them; really I'd like something with an experience closer to Heroku where that layer is as abstracted as possible.
That said, I would be very nervous to advocate using Dokku for any critical production systems. Are my fears ill founded? Or if not, is there any roadmap to making Dokku production-stable? How can people help?
It isn't limited to a single system, and has a scheduler component for Kubernetes (https://github.com/dokku/dokku-scheduler-kubernetes) and Nomad (https://github.com/dokku/dokku-scheduler-nomad).
