    You can add external IP addresses, the externalIPs option permits kube-proxy to route traffic sent to arbitrary IP addresses and on the Service ports to the endpoints of that Service.As per the official Kubernetes documentation you can add you external ip in "my-service" under spec section, you can find the details in the documentation.

    One could set the following external IPs in the Service spec, and NGINX would become available on both the NodePort and the Service port after that give the following commands.

    $ curl -D- http://myapp.example.com:port

    HTTP/1.1 200 OK

    Server: nginx/1.15.2

    $ curl -D- http://myapp.example.com

    HTTP/1.1 200 OK

    Server: nginx/1.15.2

    The myapp.example.com subdomain above resolves to both 2 IP addresses we have given.

    For more information follow External IP’s.
