This is a quick-and-dirty implementation of the Kubernetes Proxy using iptables rules.
Setup:
iptables -t nat -I PREROUTING -j my-dnat
iptables -t nat -I OUTPUT -j my-dnat
iptables -t nat -I POSTROUTING -j my-snat
/usr/bin/docker run --name kube-iptables-proxy --privileged --net=host mcluseau/kube-iptables-proxy:latest ./watch-apply
