+RethinkDB Cluster on Kubernetes
+==============================
+
+Setting up a [rethinkdb](http://rethinkdb.com/) cluster on [kubernetes](http://kubernetes.io)
+
+**Features**
+
+ * Auto configuration cluster by querying info from k8s
+ * Simple
+
+Quick start
+-----------
+
+**Step 1**
+
+Rethinkdb will discover its peer using endpoints provided by kubernetes service,
+so first create a service so the following pod can query its endpoint
+
+```sh
+$kubectl create -f examples/storage/rethinkdb/driver-service.yaml
+```
+
+check out:
+
+```sh
+$kubectl get services
+NAME              CLUSTER_IP       EXTERNAL_IP       PORT(S)       SELECTOR               AGE
+rethinkdb-driver  10.0.27.114      <none>            28015/TCP     db=rethinkdb           10m
+[...]
+```
+
+**Step 2**
+
+start the first server in the cluster
+
+```sh
+$kubectl create -f examples/storage/rethinkdb/rc.yaml
+```
+
+Actually, you can start servers as many as you want at one time, just modify the `replicas` in `rc.ymal`
+
+check out again:
+
+```sh
+$kubectl get pods
+NAME                                                  READY     REASON    RESTARTS   AGE
+[...]
+rethinkdb-rc-r4tb0                                    1/1       Running   0          1m
+```
+
+**Done!**
+
+
+---
+
+Scale
+-----
+
+You can scale up your cluster using `kubectl scale`. The new pod will join to the existing cluster automatically, for example
+
+
+```sh
+$kubectl scale rc rethinkdb-rc --replicas=3
+scaled
+
+$kubectl get pods
+NAME                                                  READY     REASON    RESTARTS   AGE
+[...]
+rethinkdb-rc-f32c5                                    1/1       Running   0          1m
+rethinkdb-rc-m4d50                                    1/1       Running   0          1m
+rethinkdb-rc-r4tb0                                    1/1       Running   0          3m
+```
+
+Admin
+-----
+
+You need a separate pod (labeled as role:admin) to access Web Admin UI
+
+```sh
+kubectl create -f examples/storage/rethinkdb/admin-pod.yaml
+kubectl create -f examples/storage/rethinkdb/admin-service.yaml
+```
+
+find the service
+
+```console
+$kubectl get services
+NAME              CLUSTER_IP       EXTERNAL_IP       PORT(S)       SELECTOR                  AGE
+[...]
+rethinkdb-admin   10.0.131.19      104.197.19.120    8080/TCP      db=rethinkdb,role=admin   10m
+rethinkdb-driver  10.0.27.114      <none>            28015/TCP     db=rethinkdb              20m
+```
+
+We request an external load balancer in the [admin-service.yaml](admin-service.yaml) file:
+
+```
+type: LoadBalancer
+```
+
+The external load balancer allows us to access the service from outside the firewall via an external IP, 104.197.19.120 in this case.
+
+Note that you may need to create a firewall rule to allow the traffic, assuming you are using Google Compute Engine:
+
+```console
+$ gcloud compute firewall-rules create rethinkdb --allow=tcp:8080
+```
+
+Now you can open a web browser and access to *http://104.197.19.120:8080* to manage your cluster.
+
+
+
+**Why not just using pods in replicas?**
+
+This is because kube-proxy will act as a load balancer and send your traffic to different server,
+since the ui is not stateless when playing with Web Admin UI will cause `Connection not open on server` error.
+
+

+
+**BTW**
+
+  * `gen_pod.sh` is using to generate pod templates for my local cluster,
+the generated pods which is using `nodeSelector` to force k8s to schedule containers to my designate nodes, for I need to access persistent data on my host dirs. Note that one needs to label the node before 'nodeSelector' can work, see this [tutorial](../../../docs/user-guide/node-selection/)
+
+  * see [antmanler/rethinkdb-k8s](https://github.com/antmanler/rethinkdb-k8s) for detail
