apiVersion: v1
kind: Pod
metadata:
  namespace: default
  name: dns-example
spec:
  containers:
    - name: test
      image: nginx
  dnsPolicy: "None"
  dnsConfig:
    nameservers:
      - 1.2.3.4
    searches:
      - ns1.svc.cluster-domain.example

Açıklaması şöyle

In the example above, the dnsPolicy is set to "None", which means that the pod will not use the default DNS settings provided by the cluster. Instead, the dnsConfig field is used to specify custom DNS settings for the pod.

The nameservers field is used to specify the DNS servers that the pod should use for DNS lookups. The searches field is used to specify the search domains that should be used for incomplete domains.

The options field is used to specify custom options for the DNS resolver, such as the ndots and edns0 options in the example above.

These settings will be used by the pod’s DNS resolver instead of the default settings provided by the cluster. For more information on pod DNS configuration, see the official docs.
