Hi all, would greatly appreciate your input as it seems to not be quite covered topic.
We have a cluster dns zone kubernetes.local. and want to gradually migrate to a default cluster.local.. The thinking was that the first step can be to configure coredns to respond across multiple zones, via changing from:
kubernetes kubernetes.local in-addr.arpa ip6.arpa
to:
kubernetes kubernetes.local cluster.local in-addr.arpa ip6.arpa
POCs did not uncover much issues with that, but are there maybe well known issues with that approach?
