The pods use the [```gcr.io/google-samples/cassandra:v12```](image/Dockerfile)
image from Google's [container registry](https://cloud.google.com/container-registry/docs/).
The docker is based on `debian:jessie` and includes OpenJDK 8. This image
includes a standard Cassandra installation from the Apache Debian repo. Through the use of environment variables you are able to change values that are inserted into the `cassandra.yaml`.

StatefulSets (previously PetSets) are a feature that was upgraded to a <i>Beta</i> component in
Kubernetes 1.5. Deploying stateful distributed applications, like Cassandra, within a clustered
environment can be challenging. We implemented StatefulSet to greatly simplify this
process. Multiple StatefulSet features are used within this example, but is out of
scope of this documentation. [Please refer to the PetSet documentation.](http://kubernetes.io/docs/user-guide/petset/)

The StatefulSet manifest that is included below, creates a Cassandra ring that consists
of three pods.
This example includes using a GCE Storage Class, please update appropriately depending
on the cloud you are working with.
