The example combines a web frontend, a redis master for storage and a replicated set of redis slaves.
### Step Zero: Prerequisites
This example assumes that you have forked the repository and turned up a Kubernetes cluster.

Once created, the service proxy on each minion is configured to set up a proxy on the specified port (in this case port 10000).
### Step Three: Turn up the replicated slave service.
### Step Three: Turn up the replicated slave tasks.
Although the redis master is a single task, the redis read slaves are a 'replicated' task, in Kubernetes, a replication controller is responsible for managing multiple instances of a replicated task. Create a file named `redis-slave-controller.json` that contains:

To play with the service itself, find the name of a frontend, grab the external IP of that host from the Google Cloud Console, and visit http://<host-ip>:8080. Note, you may need to open the firewall for port 8080 using the console or the gcloud tool.
