It might be the thing you use to power this system, but the benefits of Heroku were precisely that it didn't need you to think about the guts of a system like Kubernetes.
The magic was in the incredibly concise API, and the fact that it "just worked".
The thing that inspired me was realizing that all of the current platforms that make it easy to host apps today are built on top of Kubernetes anyways -- they just hide it all from you. I'm hoping Canine gives people an option to self host on their own Kubernetes, and with sensible defaults, get basically as easy to use of an experience.
