Check log in mdns with 'docker logs designate_mdns' command

/var/lib/kolla/venv/lib/python3.6/site-packages/oslo_policy/policy.py:809: UserWarning: Policy "delete_zone_transfer_request":"rule:admin_or_owner" was deprecated in W in favor of "delete_zone_transfer_request":"(role:admin and system_scope:all) or (role:member and project_id:%(project_id)s)". Reason:
The zone transfer request API now supports system scope and default roles.
. Either ensure your deployment is ready for the new default or copy/paste the deprecated policy into your policy file and maintain it manually.
