@Rajesh Amara Apologies for the delay in response.
The simplest way to do this is to create a DNS CNAME record which points to the FQDN of your AKS cluster.
Use the command az aks show -n <CLUSTER_NAME> -g <RESOURCE_GROUP> -o json
which will return the domain name under the key "fqdn".
Please let me know if you require more information.
