podnames

Name

podnames - Serve A/AAAA/PTR records for Pods by Pod Name.

Description

Enables Pod lookup by pod name/namespace. e.g. mypod.mynamespace.mydomain..

This does not follow the Kubernetes DNS-Based Service Discovery Specification.

This plugin requires the k8s_api and companion kubernetes plugin in https://github.com/chrisohaver/k8s_api/tree/master/examples. The kubernetes plugin must have the pods verified option.

Syntax

podnames [ZONES...] {
    ttl TTL
}

• ttl allows you to set a custom TTL for responses. The default is 5 seconds. The minimum TTL allowed is 0 seconds, and the maximum is capped at 3600 seconds. Setting TTL to 0 will prevent records from being cached.

Examples

Create records for Pods by pod name in the domain pod.cluster.local. e.g. mypod.mynamespace.pod.cluster.local.. This example eclipses the existing ip based pod.cluster.local. records that kubernetes plugin creates.

  .:53 {
    podnames pod.cluster.local in-addr.arpa ip6.arpa

    kubernetes cluster.local in-addr.arpa ip6.arpa {
      pods verified
    }

    k8s_api
  }
