My configuration:

I must say that although I'm still on Ocata I have followed the Pike
guide, as Ocata guide is missing the needed configuration for keystone
v3 (!). Although, Ocata is fully supporting the keystone v3 endpoint in
[designate] section according to release notes.


[designate]

url = https://external-domain:9001/v2
auth_uri = https://external-domain:5000

admin_auth_url = http://internal-ip:35357/v3
admin_username = neutron
admin_password = pass
admin_tenant_name = service

region_name = RegionOne
domain_name = Default
project_domain_name = Default
user_domain_name = Default
project_name = service
username = neutron
password = pass

allow_reverse_dns_lookup = True
ipv4_ptr_zone_prefix_size = 24
ipv6_ptr_zone_prefix_size = 116
insecure = True


What I've tried:
1. Using designate credentials instead of neutron
2. Adding the 'domain_name' configuration
3. removing admin_* configurations - probably bad idea, but tried anyway.


How to reproduce:
1. Configure neutron to use integrate with designate as in the guide: https://docs.openstack.org/neutron/pike/admin/config-dns-int.html
2. Create instance or a port. Port is easier and faster:
openstack port create myport --dns-name myport --network selfservice1
3. The above error would be seen in neutron-server.log, however the command will finish successfully and dns and port would be created as they should.
4. Now try deleting the port:
openstack port delete myport
5. The above error would be seen again, but on delete method, and the command will *fail*.
6. Try deleting the port again. The port should be deleted successfully.

  My configuration:

  I must say that although I'm still on Ocata I have followed the Pike
  guide, as Ocata guide is missing the needed configuration for keystone
  v3 (!). Although, Ocata is fully supporting the keystone v3 endpoint
  in [designate] section according to release notes.

  
  [designate]

  url = https://external-domain:9001/v2
  auth_uri = https://external-domain:5000

  admin_auth_url = http://internal-ip:35357/v3
  admin_username = neutron
  admin_password = pass
  admin_tenant_name = service

  region_name = RegionOne
  domain_name = Default
  project_domain_name = Default
  user_domain_name = Default
  project_name = service
  username = neutron
  password = pass

  allow_reverse_dns_lookup = True
  ipv4_ptr_zone_prefix_size = 24
  ipv6_ptr_zone_prefix_size = 116
  insecure = True


  What I've tried:
  1. Using designate credentials instead of neutron
  2. Adding the 'domain_name' configuration
  3. removing admin_* configurations - probably bad idea, but tried anyway.

  
  How to reproduce:
  1. Configure neutron to use integrate with designate as in the guide: https://docs.openstack.org/neutron/pike/admin/config-dns-int.html
  2. Create instance or a port. Port is easier and faster:
  openstack port create myport --dns-name myport --network selfservice1
  3. The above error would be seen in neutron-server.log, however the command will finish successfully and dns and port would be created as they should.
  4. Now try deleting the port:
  openstack port delete myport
  5. The above error would be seen again, but on delete method, and the command will *fail*.
  6. Try deleting the port again. The port should be deleted successfully.
