Just a funny note: when we created this repository, it was for our CI
purpose and I see there are a lot of people using it now for testing
purpose. I think this is good because it helps people to get involved
in the modules.

Well, if you're familiar with Puppet, you'll notice that we're not
using Hiera or dynamic site.pp, so there is some amount of work before
we can run it in multinode.
Though we have tried and we are still thinking about it. We'll have
this discussion at OpenStack Summit, so hopefully we can have plans
for Newton about it.

If you need to start a composition layer from scratch, you'll need to
compose the manifests yourself.
Puppet OpenStack is not an opinionated project like TripleO, Fuel,
Kolla. We're a library of Puppet modules that you can use at wish.
You need to be a bit familiar with Puppet.
But if you look at wat we do in puppet-openstack-integration, you're
missing a few parameters to make it work in multi-node, it should not
be hard.

Thanks for bringing this up,
