i have a cluster running on aws ec2 and not a managed EKS, i'm trying to add a loadbalancer to the cluster without restarting it or initializing a new node, is that possible ? i've already set the permission and tags related to this post https://blog.heptio.com/setting-up-the-kubernetes-aws-cloud-provider-6f0349b512bd But the thing is that we must add the flag --cloud-provider=aws to the Kubelet before adding the node to the cluster. Is there any other options or other way to do it ? kubectl get nodes
