+## Glusterfs
+
+[Glusterfs](http://www.gluster.org) is an open source scale-out filesystem. These examples provide information about how to allow containers use Glusterfs volumes.
+
+The example assumes that you have already set up a Glusterfs server cluster and the Glusterfs client package is installed on all Kubernetes nodes.
+
+### Prerequisites
+
+Set up Glusterfs server cluster; install Glusterfs client package on the Kubernetes nodes. ([Guide](http://gluster.readthedocs.io/en/latest/Administrator%20Guide/))
+
+### Create endpoints
+
+Here is a snippet of [glusterfs-endpoints.json](glusterfs-endpoints.json),
+
+```
+      "addresses": [
+        {
+          "IP": "10.240.106.152"
+        }
+      ],
+      "ports": [
+        {
+          "port": 1
+        }
+      ]
+
+```
+
+The "IP" field should be filled with the address of a node in the Glusterfs server cluster. In this example, it is fine to give any valid value (from 1 to 65535) to the "port" field.
+
+Create the endpoints,
+
+```sh
+$ kubectl create -f examples/volumes/glusterfs/glusterfs-endpoints.json
+```
+
+You can verify that the endpoints are successfully created by running
+
+```sh
+$ kubectl get endpoints
+NAME                ENDPOINTS
+glusterfs-cluster   10.240.106.152:1,10.240.79.157:1
+```
+
+We need also create a service for this endpoints, so that the endpoints will be persistented. We will add this service without a selector to tell Kubernetes we want to add its endpoints manually. You can see [glusterfs-service.json](glusterfs-service.json) for details.
+
+Use this command to create the service:
+
+```sh
+$ kubectl create -f examples/volumes/glusterfs/glusterfs-service.json
+```
+
+
+### Create a POD
+
+The following *volume* spec in [glusterfs-pod.json](glusterfs-pod.json) illustrates a sample configuration.
+
+```json
+{
+     "name": "glusterfsvol",
+     "glusterfs": {
+        "endpoints": "glusterfs-cluster",
+        "path": "kube_vol",
+        "readOnly": true
+    }
+}
+```
+
+The parameters are explained as the followings.
+
+- **endpoints** is endpoints name that represents a Gluster cluster configuration. *kubelet* is optimized to avoid mount storm, it will randomly pick one from the endpoints to mount. If this host is unresponsive, the next Gluster host in the endpoints is automatically selected.
+- **path** is the Glusterfs volume name.
+- **readOnly** is the boolean that sets the mountpoint readOnly or readWrite.
+
+Create a pod that has a container using Glusterfs volume,
+
+```sh
+$ kubectl create -f examples/volumes/glusterfs/glusterfs-pod.json
+```
+
+You can verify that the pod is running:
+
+```sh
+$ kubectl get pods
+NAME             READY     STATUS    RESTARTS   AGE
+glusterfs        1/1       Running   0          3m
+
+$ kubectl get pods glusterfs -t '{{.status.hostIP}}{{"\n"}}'
+10.240.169.172
+```
+
+You may ssh to the host (the hostIP) and run 'mount' to see if the Glusterfs volume is mounted,
+
+```sh
+$ mount | grep kube_vol
+10.240.106.152:kube_vol on /var/lib/kubelet/pods/f164a571-fa68-11e4-ad5c-42010af019b7/volumes/kubernetes.io~glusterfs/glusterfsvol type fuse.glusterfs (rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072)
+```
+
+You may also run `docker ps` on the host to see the actual container.
