I agree with that - but would like to clarify the 'bare metal, VMs and
containers' part a bit. (an in fact, I was concerned in the meeting that
the messaging around this would be confusing because we 'supporting bare
metal' and 'supporting containers' mean two different things but we use
one phrase to talk about it.
It's abundantly clear at the strategic level that having OpenStack be
able to provide both VMs and Bare Metal as two different sorts of
resources (ostensibly but not prescriptively via nova) is one of our
advantages. We wanted to underscore how important it is to be able to do
that, and wanted to underscore that so that it's really clear how
important it is any time the "but cloud should just be VMs" sentiment
The way we discussed "supporting containers" was quite different and was
not about nova providing containers. Rather, it was about reaching out
to our friends in other communities and working with them on making
OpenStack the best place to run things like kubernetes or docker swarm.
Those are systems that ultimately need to run, and it seems that good
integration (like kuryr with libnetwork) can provide a really strong
story. I think pretty much everyone agrees that there is not much value
to us or the world for us to compete with kubernetes or docker.
So, we do want to be supportive of bare metal and containers - but the
specific _WAY_ we want to be supportive of those things is different for
