Open Stack

I re-read this and maybe you mean, some containers will live only outside of k8s and some will live in k8s, not that you want to to support not having k8s at all with the same code base? That would be a much easier thing, and agree ansible would be very good at that.

Thanks,
Kevin

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.
