Bug 2088268

Hi. This Bugzilla is different from https://bugzilla.redhat.com/show_bug.cgi?id=1813565

This Bugzilla is only related with  CONF.nova.availability_zone in octavia.conf  
but BZ 1813565 is only related with providing input of AZ. 


Please see the logic below

        try:
            network_ids = network_ids or []
            port_ids = port_ids or []
            nics = []
            if network_ids:
                nics.extend([{"net-id": net_id} for net_id in network_ids])
            if port_ids:
                nics.extend([{"port-id": port_id} for port_id in port_ids])

            server_group = None if server_group_id is None else {
                "group": server_group_id}
            az_name = availability_zone or CONF.nova.availability_zone     <-- it is either by input for each lb or by conf globally (CONF.nova.availability_zone)
            ...
            amphora = self.manager.create(
                name=name, image=image_id, flavor=amphora_flavor,
                block_device_mapping=block_device_mapping,
                key_name=key_name, security_groups=sec_groups,
                nics=nics,
                files=config_drive_files,
                userdata=user_data,
                config_drive=True,
                scheduler_hints=server_group,
                availability_zone=az_name
            )

I've updated this BZ from Train to Wallaby since CONF.nova.availability_zone is still part of the new release, Wallaby,
and both of providing AZ for each LB creation and globally setting AZ to all LB still exist.

RHOSP 17.1 GAed the ability to select an availability zone on creation for Octavia amphora load balancers, see [1].  This functionality supercedes what is requested here, so I am marking this closed.
