DNS as a service in openstack

I've successfully installed designate on test openstack. Idea is now to create instance that will act as a DNS server. Can you suggest any DNS image for opensatack?

I've read bunch of documentation and watched summit videos, but there isn't any practical example use case.

Designate doesn't deploy DNS services on instances.

I understand that it doesn't deploy them, but only provides REST API for managing them. However, I wanted practical scenario to test how it works and wondered if anybody can point me in the right direction.

Well, the point of Designate is to not install DNS on a server or instance. You leave that to Designate.

How it works? Use openstack commands to create a zone and create/delete/update records in that zone. E.g. https://docs.platform9.com/support/ge....

Use the Designate DNS server by putting the Designate IP(s) into /etc/resolve.conf.

Is this right: 1.You install Designate on openstack. 2. You install some kind of DNS server (bind9) directly on compute node. 3. Bind9 acts as a DNS for your cloud. 4. Designate is an API that you culd use to add records, zones etc. You can also do it through CLI on compute node.
