Are you able to specify and get around it?  I have one loadbalancer for my cloudfoundry deployment but am not very familiar with Octavia…the loadbalancer was created through a terraform script so I didn’t get into the internals.

Subject: [Bug 1943069] Re: Heat fails to create magnum swarm cluster with allowed_cidrs not assigned
I do have the exact same problem.  One additional information is that I
am not selecting any loadbalancing to the cluster and the error is
related to it.
