As I am new to coredns configurations in kubernetes and I'm trying to explore plugins provided by coredns in kubernetes. I see a plugin named local which will respond with a reply to local requests. But I could not understand a use-case where this plugin will be exactly useful for. Can someone explain with an example how it can be make use of? Also in unbound configuration man page, I see an option called local-zone: .
local-zone: Configure a local zone. The type determines the answer to give if there is no match from local-data. The types are deny, refuse, static, transparent, redirect, nodefault, typetransparent, and are explained below. After that the default settings are listed. Use local-data: to enter data into the local zone. Answers for local zones are authoritative DNS answers. By default the zones are class IN.
nodefault: Used to turn off default contents for AS112 zones. The other types also turn off default contents for the zone. The 'nodefault' option has no other effect than turning off default contents for the given zone.
Is this local plugin behaves similar to this unbound local-zone option? If not, Is there any plugin which act similar to local-zone in unbound ? I am expecting a coredns plugin to behave similar to local-data in unbound particularly for nodefault type in local-data. eg: local-zone: nodefault. It would be really helpful if someone helps me to clear out this. Thanks in advance!!!
