I'm using Kubernetes on AWS, and for various reasons I needed to set up the cluster myself instead of using kube-up or kube-aws. 
This is working fine, but now I would really like to be able to create a NodePort service and have Kubernetes use ELB for external load balancing.

Is there either a way to configure my **existing** Kubernetes cluster to use the AWS CloudProvider, or to **manually** create a new cluster with the AWS CloudProvider **without** using kube-up or kube-aws?
