I am trying to create an OS::Heat::ResourceGroup of VMs and assign each VM a floating IP. As far as I know this requires cross-referencing the VM, port, and floating IP resources. How can I do that within a OS::Heat::ResourceGroup definition?

The `port: { get_resource: vm_cluster.vm_port.0 }` below is rejected by Heat.

Any help appreciated.

Thanks,
Tomasz
