Neutron LBaaS - VIP Resource Modify create/delete/update methods

[Rabi Mishra]

All life-cycle methods for the new VIP Resource (refer bug #1280165) need to be implemented differently.

Without the existence of the neutron VIP resource earlier; 'handle_create','handle_update','handle_delete' handle methods use heat 'db_api' and 'nova_client' to implement this. This should be changed.

Current implementation below:
-----------------------------------------------
 def handle_create(self):
        pool = self.properties[self.POOL_ID]
        client = self.neutron()
        nova_client = self.nova()
        protocol_port = self.properties[self.PROTOCOL_PORT]

        for member in self.properties.get(self.MEMBERS):
            address = nova_utils.server_to_ipaddress(nova_client, member)
            lb_member = client.create_member({
                'member': {
                    'pool_id': pool,
                    'address': address,
                    'protocol_port': protocol_port}})['member']
            db_api.resource_data_set(self, member, lb_member['id'])

Wanted to note that Heat documentation is somewhat lacking for the VIP resource. In the Pool list, there's an attribute vip which is the "Vip associated with the pool." No mention on what properties are available within the VIP though. It would be great to address the gap when working on this bug.

Anne, thank you for the good point. You are right it's really missed. Unfortunatelly the works is blocked by changes in neutron. AFAIK, they have new model and the reason, why we did not fix it yet, is we wait changes in neutron for improving or reworking current implemenation in heat. I hope when we start change LB in heat we update all documentation and make it more similar on neutron. Thanks.
