Open Stack

I think if you try to go down the Kubernetes & !Kubernetes path, you'll end up re-implementing pretty much all of Kubernetes, or you will use Kubernetes just like !Kubernetes and gain very little benefit from it.

Thanks,
Kevin

Yes!

Thanks for pointing this out as this is one of the reasons why I was proposing
ansible as our common interface w/o any extra layer.

I'll probably start a new etherpad for this as I would prefer not to distract
the rest of the TripleO + ansible discussion. At the end, if ansible ends up
being the tool we pick, I'll make sure to update your etherpad.
