In the deployment file keep the type as LoadBalancer and then create a service for it.
Execute this command to get the ip of your load balancer:
kubectl describe services example-service
You'll see something like this:
LoadBalancer Ingress: 220.127.116.11
Port: <unnamed> 80/TCP
NodePort: <unnamed> 32445/TCP
Session Affinity: None
That'll be your load balancer's IP
