### Step One: Create the Redis master pod<a id="step-one"></a>
Use the `examples/guestbook-go/redis-master-controller.json` file to create a [replication controller](https://kubernetes.io/docs/concepts/workloads/controllers/replicationcontroller/) and Redis master [pod](https://kubernetes.io/docs/concepts/workloads/pods/pod-overview/). The pod runs a Redis key-value server in a container. Using a replication controller is the preferred way to launch long-running pods, even for 1 replica, so that the pod benefits from the self-healing mechanism in Kubernetes (keeps the pods alive).

This is a simple Go `net/http` ([negroni](https://github.com/codegangsta/negroni) based) server that is configured to talk to either the replica or master services depending on whether the request is a read or a write. The pods we are creating expose a simple JSON interface and serves a jQuery-Ajax based UI. Like the Redis replica pods, these pods are also managed by a replication controller.
