 In Kubernetes, the atomic unit of an application is a [_Pod_](../../docs/user-guide/pods.md).  A Pod is one or more containers that _must_ be scheduled onto the same host.  All containers in a pod share a network namespace, and may optionally share mounted volumes.
 In this simple case, we define a single container running Cassandra for our pod:

 There are a few things to note in this description.  First is that we are running the [```gcr.io/google_containers/cassandra:v6```](image/Dockerfile) image from Google's [container registry](https://cloud.google.com/container-registry/docs/).  This is a standard Cassandra installation on top of Debian.  However it also adds a custom [```SeedProvider```](https://svn.apache.org/repos/asf/cassandra/trunk/src/java/org/apache/cassandra/locator/SeedProvider.java) to Cassandra.  In Cassandra, a ```SeedProvider``` bootstraps the gossip protocol that Cassandra uses to find other nodes.  The [```KubernetesSeedProvider```](#seed-provider-source) discovers the Kubernetes API Server using the built in Kubernetes discovery service, and then uses the Kubernetes API to find new nodes (more on this later)
