It is useful if your services with Type LoadBalancer having firewall restrictions.
/kube-elb-security -alsologtostderr
In that case all required information would be taken from AWS instance metadata
Pod needs to be running on master node due to AWS InstanceProfile permissions
docker build --tag kube-elb-security .
docker run -it --rm kube-elb-security /kube-elb-security -logtostderr -inCluster=false -region=us-east-1 -vpc-id=vpc-01234567
By default controller watches on services with label app=ingress-nginx
Could be defined by flag -labelSelector=app=myapp
