In RHCL 1.3, we will be including the new DNS Failover feature, which is enabled via the addition of groups to the DNS Operator. This will require some documentation:

• How to migrate existing clusters to use groups and ensure uptime is unaffected - this can also serve for setting up new clusters.
• How to view and modify which groups are active.
• How to see the effect of groups for a particular DNS record.

RFC: https://github.com/Kuadrant/architecture/blob/main/rfcs/0014-dns-failover.md

We are also moving CoreDNS from developer preview to full release, this feature takes advantage of the delegation feature in the DNS Operator. This will also require documention:

• How to set up a set of clusters to use CoreDNS.
• How To configure delegation properly (primaries and secondaries).
• How to confirm DNS Records are being published.
