#### 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`

**NOTE:** The environment variable `ISTIO_CLUSTER_ISGKE` is assumed to be set to `true` if the cluster
is a GKE cluster.

```bash
ISTIO_CNI_ARGS=
# TODO: What k8s data can we use for this check for whether GKE?
if [[ "${ISTIO_CLUSTER_ISGKE}" == "true" ]]; then
    ISTIO_CNI_ARGS="--set cni.cniBinDir=/home/kubernetes/bin"

  ## If undefined (the default) or set to null, no storageClassName spec is
