Debug Queries in CoreDNS with the etcd Middleware

Sun, 22 May 2016 21:32:35 +0100

Let’s say you have some data in etcd and use CoreDNS for service discovery. The Corefile looks like this:

.:53 {
    etcd skydns.local {
        stubzones
        path /skydns
        endpoint http://localhost:2379
        upstream 8.8.8.8:53 8.8.4.4:53
        debug  # <-- new, purpose of this blog
    }
}

You test with dig and you get the result below and you’re asking yourself wth is this happening? If you have access to etcd directly you can use etcdctl, if not you’re basically stuck.
