I use tripleo to deploy a single node aio with only 1 network interface
as a lab at home. You can see the configuration here:

 https://github.com/hjensas/homelab/tree/master/overcloud

Basically I use a an empty network data file, and removed
the 'networks' section in my custom role data file.

With no networks defined everything is placed on the 'ctlplane' (i.e
provisioning network). Same thing you are asking for?


I think you can do the same thing. For the provider networks I believe
you will need per-role NeutronBridgeMappings i.e something like:

 ControllerParameters:
   NeutronBridgeMappings: br-ex:provider0
 ComputeSite1:
   NeutronBridgeMappings: br-foo:provider1
 ComputeSite2:
   NeutronBridgeMappings: br-bar:provider2
