Octavia v2 API Requesting a VIP address is not working

[Michael Johnson]

When I create a new load balancer requesting an vip address from the subnet specified, I do not get the requested VIP address.

(octaviaclient) michjohn@devstackpy27:~/.../testclient/python-octaviaclient$ openstack loadbalancer create --name "my lb" --subnet private-subnet --description "My description" --vip-address 10.0.0.66

Querying the neutron database, 10.0.0.66 is available on the subnet requested.

[Pradeep Kumar Singh (pradeep-singh-u)]

Hello Michal,

I have analysed the issue, below are my findings.

When we call v1 apis via neutron, port is already provided to octavia, so octavia need not to do any thing[1].
But when we use V2 api and don't provide the port_id, then port is created in octavia[1]

Then in DB fixed IP of this port is assigned to vip.ip_address[2].

If my understanding is correct i will fix it by assigning the vip.ip_address to port during its creation.

Could you please confirm my understanding.

Pradeep, you are right, when we create the port on Octavia, the ip_address is not specified.

I want to get this fixed by RC1 next week, so I hope you don't mind if I push up a patch for it. I will put you down as a co-author. I don't see a currently open patch.

It looks like Cheng already fixed this as part of fixing another bug.
