NS record with CRD source

You can create NS records with the help of CRD source

Consider the following example

apiVersion: externaldns.k8s.io/v1alpha1
kind: DNSEndpoint
metadata:
  name: ns-record
spec:
  endpoints:
  - dnsName: zone.example.com
    recordTTL: 300

    targets:
    - ns1.example.com
    - ns2.example.com
