#### 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.

// StatefulSet represents a set of pods with consistent identities.
// Identities are defined as:
//   - Network: A single stable DNS and hostname.
//   - Storage: As many VolumeClaims as requested.
//
// The StatefulSet guarantees that a given network identity will always
// map to the same storage identity.
