Comment 2 for bug 1756329

Bind won't stop you from creating and deleting domains that already exist upstream.

openstack zone create ubuntu.com. --email <email address hidden>
openstack zone delete <uuid>

However, the post cleanup will fail in designate.
It will give you an error in that bind is not 'SOA' (Start of Authority record) for a given domain.

"Failed to get expected response while trying to send 'SOA' for 'ubuntu.com.' to '10.218.5.38:53'."

In other wards do 'nslookup <domain>' prior to creating the domain or you will need to delete it manually from the database;

use deignate;
select * from zones where name like '%ubuntu%';
