Example middleware for CoreDNS

example's Issues

deploys fails

I try to deploy coredns in my k8s 1.9 using your example configs.

no matter I remove serviceaccountname or not, it causes the same error: is this coded in your code in this version or did I do something wrong ?

2018/04/27 03:37:48 plugin/kubernetes: open /var/run/secrets/kubernetes.io/serviceaccount/token: no such file or directory

add health.Healther

Add health.Healther to show how this is done.

Example is not compiling

The mod was recnetly removed, and there's no information about how to build from scratch without the mod.

if you remove the mod then you will need to document what dependencies should be included on the $GOPATh, and how to do it please?

This PR would fix this issue, which is pretty much re-adding the module, but if this is not desirable than an alternative needs to be documented.

Nothing is printed by the plugin

$ git clone https://github.com/coredns/coredns.git
$ cd coredns/plugin
$ git clone https://github.com/coredns/example
$ cd ..
$ vim plugin.cfg
# Comments here.
log:log
example:example
# Nothing else in this file.
$ make
$ vim ./Corefile
. {
  example
}
$ ./coredns -dns.port 1337
# In another terminal:
$ dig @127.0.0.1 -p 1337 example.com
# Expected: "example" must be printed in the `./coredns` output.
# Actually: 
$ ./coredns -dns.port 1337 
.:1337
CoreDNS-1.7.0

add metrics

Add a simple metrics to show how this is done.

Example doesn't print anything

Example plugin does not print anything using provided Corefile

.:1053 {
example
log
forward . 8.8.8.8
}

Sample output:
CoreDNS-1.11.1
linux/amd64, go1.20.12, 945db2fa-dirty
[INFO] 127.0.0.1:45207 - 6605 "A IN google.com. udp 39 false 4096" NOERROR qr,rd,ra 195 0.002194196s

Also a new plugin created using the instructions provided for creating plugins similarly does not print anything

I have tried moving the example plugin around in the corefile with no differences viewed.
