instruction: Create a Kubernetes Service configuration with best practices
output: ```dockerfile
  from the IPv4 and IPv6 address blocks using
  kubectl describe. You may then validate access to the service via the IPs and ports.kubectl describe svc -l app.kubernetes.io/name=MyApp
  Name: my-service
  Namespace: default
  Labels: app.kubernetes.io/name=MyApp
  Annotations: <none>
  Selector: app.kubernetes.io/name=MyApp
  Type: ClusterIP
  IP Family Policy: PreferDualStack
  IP Families: IPv4,IPv6

  Create a dual-stack load balanced ServiceIf the cloud provider supports the provisioning of IPv6 enabled external load balancers,
  create the following Service with PreferDualStack in .spec.ipFamilyPolicy, IPv6 as
  the first element of the .spec.ipFamilies array and the type field set to LoadBalancer.service/networking/dual-stack-prefer-ipv6-lb-svc.yaml
  apiVersion: v1
  kind: Service
  metadata:
   name: my-service
   labels:
   app.kubernetes.io/name: MyApp
  spec:
   ipFamilyPolicy: PreferDualStack
   ipFamilies:
   - IPv6
   type: LoadBalancer
   selector:
   app.kubernetes.io/name: MyApp
   ports:
   - protocol: TCP
   port: 80
  Check the Service:kubectl get svc -l app.kubernetes.io/name=MyApp
  Validate that the Service receives a CLUSTER-IP address
