Question is similar to following SO question. But I am not looking forward to create classic load balancer.
How to create Kubernetes load balancer on aws
AWS now provide 2 types of loadbalancer, classic load balancer and application load balancer. Please read following document for more information,
https://aws.amazon.com/blogs/aws/new-aws-application-load-balancer/
I already know how classic load balancer work with kubernetes. I wonder if there is any flag/ tool exist so that we can also configure application loadbalancer.
An AWS ALB Ingress Controller has been built which you can find on GitHub: https://github.com/coreos/alb-ingress-controller
I can tell you that as of K8 v1.2.3/4 there is no built-in support for Application Load Balancers.
That said, what I do is expose internally load balanced pods via a service NodePort. You can then implement any type of AWS load balancing you would like, including new Application Load Balancing features such as Content-Based Routing, by setting up your own AWS ALB that directs a URL path like /blog to a specific NodePort.
You can read more about NodePorts here: http://kubernetes.io/docs/user-guide/services/#type-nodeport
For bonus points, you could script the creation of the ALB via something like BOTO3 and have it provisioned when you provision the K8 services/pods/rc.
