Fixes #51

Tested with kops + AWS.

Testing steps

Start a simple http server deployment:

kubectl -n default run alpine --command --image alpine --replicas 2 --port 80 -- httpd -fv

Expose as LB type service:

kubectl -n default expose deployment alpine --port 8888 --target-port 80 --type=LoadBalancer

Check Services and EPs:

$ kubectl -n default get service,ep -o wide

ep/kubernetes   172.20.43.207:443             35m

Hit the external LB IP, got a 404 from the server (OK).

curl aa5fdbd3a667c11e7b2ff0691ff4e598-286081594.us-west-2.elb.amazonaws.com:8888

Check http server logs:

for i in $(kubectl -n default get pods -l run=alpine --output name)
do
  kubectl -n default logs $(basename ${i})
done

output snippet:
