IPAM Controller doesnt release FQDN/IP #9

Open jmcalalang opened 3 years ago

jmcalalang commented 3 years ago

This may be intentional, but when deleting a virtualserver resource the IP address and FQDN are not released from the F5IPAM.

@jmcalalang IPAM Controller works according to the Spec of the F5IPAM resource. If a VirtualServer resource gets deleted, the corresponding Ingress Controller should remove the associated entry from the Spec of F5IPAM resource, then IPAM Controller releases the IP address.

But it doesn't. You can see there I didn't have any resources, but in F5IPAM, they still show up. Was there a change in a recent release to fix this?
