You had me at Docker.. 

"Kubernetes establishes robust declarative primitives for maintaining
the desired state requested by the user. We see these primitives as
the main value added by Kubernetes. Self-healing mechanisms, such as
auto-restarting, re-scheduling, and replicating containers require active
controllers, not just imperative orchestration."

But the bit above has me a bit nervous...

I'm not exactly ignorant of what declarative orchestration is, and of
late I've found it to be more trouble than I had previously imagined it
would be. All of the features above are desirable in any application,
whether docker managed or not, and have been discussed for Heat
specifically. I'm not entirely sure I want these things in my OpenStack
deployment, but it will be interesting to see if there are operators who
want them bad enough to deal with the inherent complexities of trying to
write such a thing for an application as demanding as OpenStack.

Anyway, I would definitely be interested in seeing if we can plug it
into the interfaces we already have for image building, config file and
system state management. Thanks for sharing, and see you in the
deployment trenches. :)
