*   The canonical arguments for running all Windows e2e tests against a cluster
    on GCE can be seen by searching for `--test-cmd-args` in the
    [test configuration](https://github.com/kubernetes/test-infra/blob/master/config/jobs/kubernetes/sig-windows/windows-gce.yaml#L78)
    for the `ci-kubernetes-e2e-windows-gce` continuous test job. These arguments
    should be passed to the `run-e2e` script; escape the ginkgo arguments by

# GCE Load-Balancer Controller (GLBC) Cluster Addon

This cluster addon is composed of a 404 default backend service and deployment.
On GCE, this 404 service is used in conjunction with the
[Ingress-GCE](https://github.com/kubernetes/ingress-gce) controller.
