Hi,

If you're talking about the Amphorae instances, you can use the loadbalancer amphora API or CLI to get the IDs of the Octavia Amphorae:

For instance:

$ openstack loadbalancer amphora list --loadbalancer lb1
+--------------------------------------+--------------------------------------+-----------+------------+---------------+-------------+
| id                                   | loadbalancer_id                      | status    | role       | lb_network_ip | ha_ip       |
+--------------------------------------+--------------------------------------+-----------+------------+---------------+-------------+
| 3973f489-4820-4c52-a506-4ebb5ea9d334 | 46eb4f44-9785-4090-9b1a-f8f390cc539e | ALLOCATED | STANDALONE | 192.168.0.148 | 172.24.4.96 |
+--------------------------------------+--------------------------------------+-----------+------------+---------------+-------------+

Here the amphora id is 3973f489-4820-4c52-a506-4ebb5ea9d334

Then it's easy to get the instance in Nova, its name is "amphora-<amphora_id>":

$ openstack server list --all | grep amphora
| d5455ab1-fc67-48ca-bf66-0df4a248c74b | amphora-3973f489-4820-4c52-a506-4ebb5ea9d334 | ACTIVE | lb-mgmt-net=192.168.0.148; public=172.24.4.14                         | amphora-centos-stream    | m1.amphora |

Keep in mind that the lifecycle of those instances is managed by the Octavia services, it's not recommended to perform changes on them.
