I have an OVN network set up and running on an Incus cluster. I’m trying to add basic DNS functionally similar to what Dnsmasq provided out of the box for the natt’d bridge. Ideally, I don’t want to run external DNS servers. I understand that I could create a few containers across the cluster for this purpose, but I don’t want to have to manage and monitor another service.
OVN doesn’t have a built-in DNS server and its distributed design makes it difficult to have one.
What it does is it uses the upstream DNS servers you set on your uplink network.
It then intercepts DNS requests headed to those servers and returns its own local records for things like the .incus zone.
