#### GKE via Stackdriver Log Viewer

Each GKE cluster's will have many categories of logs collected by Stackdriver.  Logs can be monitored via
the project's [log viewer](https://cloud.google.com/logging/docs/view/overview) and/or the `gcloud logging read`
capability.

  // This service must exist before the StatefulSet, and is responsible for

  // where "pod-specific-string" is managed by the StatefulSet controller.

This is a work in progress - building on top of the multi-cluster installer.

As an extreme, the goal is to be possible to run Istio workloads in a cluster without installing any Istio component
in that cluster. Currently, the minimum we require is the security provider (node agent or citadel).
