Similar to local-up cluster, kube-proxy in [clusters running on GCE](https://kubernetes.io/docs/getting-started-guides/gce/) run in IPTABLES mode by default. Users need to export the env `KUBE_PROXY_MODE=ipvs` before [starting a cluster](https://kubernetes.io/docs/getting-started-guides/gce/#starting-a-cluster):
```shell
#before running one of the commands chosen to start a cluster:
# curl -sS https://get.k8s.io | bash
# wget -q -O - https://get.k8s.io | bash

Construction should NOT actually start running all of these things, do I/O, or block in anyway.

Running the controller actually starts processing things.
Normally, this just means running the queue.
All informers created by `kube.Client` are kept track in the client, and started in one go with `RunAndWait` in one centralized call.
