Question

A county needs Pods to resolve an on-prem Active Directory DNS zone for internal directories. How is that commonly configured with CoreDNS?

Accepted Answer

Customize the CoreDNS ConfigMap with a stub domain or forward rule for that external DNS zone — Teach CoreDNS about the other building: put a stub or forward for the AD zone in the CoreDNS ConfigMap so cluster Pods can ask the right external DNS for those names.

Answer

Add the AD zone as an Ingress host rule so CoreDNS inherits it automatically

Answer

Rename the cluster domain to the AD FQDN on every Deployment annotation

Answer

Create a Gateway listener named after the AD zone to publish SRV records
