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?
There are a few places where you'd need to add the --cloud-provider=aws flag to your existing cluster: all kubelets, the apiserver, and the controller manager. You may also need to configure IAM roles to ensure that the VMs can make successful calls to the cloud provider (check the errors logs for 403 responses).
For RHEL7, edit the following files on the master:
On minions, edit the following files:
