## Guestbook Example |
This example shows how to build a simple multi-tier web application using Kubernetes and Docker. The application consists of a web front end, Redis master for storage, and replicated set of Redis replicas, all for which we will create Kubernetes replication controllers, pods, and services. |
If you are running a cluster in Google Container Engine (GKE), instead see the [Guestbook Example for Google Container Engine](https://cloud.google.com/container-engine/docs/tutorials/guestbook). |

### Step Zero: Prerequisites <a id="step-zero"></a> |
This example assumes that you have a working cluster. See the [Getting Started Guides](https://kubernetes.io/docs/setup/) for details about creating a cluster. |
**Tip:** View all the `kubectl` commands, including their options and descriptions in the [kubectl CLI reference](https://kubernetes.io/docs/user-guide/kubectl-overview/). |
### Step One: Create the Redis master pod<a id="step-one"></a> |
Use the `examples/guestbook-go/redis-master-controller.yaml` 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 co... |
1. Use the [redis-master-controller.yaml](redis-master-controller.yaml) file to create the Redis master deployment in your Kubernetes cluster by running the `kubectl create -f` *`filename`* command: |
```console |
$ kubectl create -f guestbook-go/redis-master-controller.yaml |
``` |
2. To verify that the redis-master controller is up, list the deployments you created in the cluster with the `kubectl get deployments` command(if you don't specify a `--namespace`, the `default` namespace will be used. The same below): |
```console |
$ kubectl get deployments |
NAME READY UP-TO-DATE AVAILABLE AGE |
redis-master 1/1 1 1 33m |
