Hello,

Is Octavia (Ocata version) supposed to work with Heat (tested with Newton version) deployment? I launch a Heat stack trying to deploy a load balancer with a single listener/pool and two members. While the Heat shows status COMPLETE and the Neutron shows all objects as created, Octavia creates the listener, the pool but with a single member (instead of two).
Another example: I launch a Heat stack trying to deploy a load balancer with a multiple listeners/pools each having two members. The results is that Heat shows status COMPLETE and the Neutron shows all objects as created, Octavia creates the listeners, but only some of the pools and for those pool creates only one member or none.
In the Octavia log I could see only these type of errors:

2017-07-26 08:12:08.639 1 INFO octavia.api.v1.controllers.member [req-749be397-dd63-4fb6-9d86-b717f6d59e3d - 989bbadfe4134722b478ca799217833e - default default] Member cannot be created or modified because the Load Balancer is in an immutable state
2017-07-26 08:12:08.698 1 DEBUG wsme.api [req-749be397-dd63-4fb6-9d86-b717f6d59e3d - 989bbadfe4134722b478ca799217833e - default default] Client-side error: Load Balancer b12a29db-81d0-451a-af9c-d563b636bf01 is immutable and cannot be updated. format_exception /opt/octavia/lib/python2.7/site-packages/wsme/api.py:222

I think what happens is that it takes some time until the configuration is updated on an amphora and during that time the Load Balancer is in UPDATE state and new configuration cannot be added.

Is this scenario validated or it is still work in progress?

Thanks,
Mihaela Balas
