How to set the Pod DNS in Kubernetes

I wanted to know if there is any way that I can set a DNS for the Pod in the StatefulSet, so I can call them directly.

I have read the Kubernetes documentation, but I haven’t seen anything useful.

>Solution :

you can set a DNS name for Pods in a StatefulSet using the serviceName field in the StatefulSet's spec section.

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: my-statefulset
spec:
  serviceName: my-dns-name # set the DNS name for the Pods
