Yeah, Rancher is great with Kubernetes too - It sets it up for you on your favourite infrastructure provider and launches instances for you.

Is it? 1.1.x looked nice when I had evaluated it (especially the Web UI), but was a real bugs nest in the long run. Had issues with almost every component. Usually found matching bugs that were already filed and had the workarounds described, but it left the bad aftertaste.

Finally, DNS component had nearly malfunctioned and I've switched to Compose with some WeaveNet and semi-manual (re)scheduling. Lost some useful functionality (and the UI) but at least the switch fixed things and it works. Wanted to use Swarm for fully automated scheduling without a DIY external watchdog system, but its networking is extremely limited at the moment (and I haven't groked how to use it with Weave).

Kubernetes looks nice, but the amount of YAML I'll have to write scares me away. And I'm not sure I trust all that "we do magic" stuff anymore. The more complicated system is, the harder it's to figure out what to do when it starts to fail.
