As detailed in https://coredns.io/2017/03/01/how-to-add-plugins-to-coredns/#4-hooking-it-up, looks like the new plugin needs to be added to plugin.cfg and some code to be generated with "go generate && go build". Since node-cache vendors in coredns repo, you might be able to do it there for local testing.

Any update here? Closing for now, please reopen if needed.

I copied part of the code and wrote a tool, there is no need to introduce additional plug-ins to do what I want
