Examples

• examples/kubernetes - is a copy of CoreDNS's built-in kubernetes plugin (circa 1.7.0), refactored to use the k8s_api plugin. It registers 4 informers: "service", "endpoints", "namespace", and "pod" (if pods verified is declared).

• examples/podnames - enable Pod lookup by podname/namespace. e.g. mypod.mynamespace.pod.cluster.local. It uses the "pod" informer created by the examples/kubernetes plugin above. e.g.

  plugin.cfg:

  ...
  podnames:github.com/chrisohaver/k8s_api/examples/podnames
  kubernetes:github.com/chrisohaver/k8s_api/examples/kubernetes
  k8s_api:github.com/chrisohaver/k8s_api/k8s_api
  ...
  

  Corefile:

  .:53 {
    podnames pod.cluster.local in-addr.arpa ip6.arpa {
      ttl 5
    }
  
    kubernetes cluster.local in-addr.arpa ip6.arpa {
      pods verified
    }
  
    k8s_api
  }
