+## Cloud Native Deployments of Hazelcast using Kubernetes v1beta3 api
+
+The following document describes the development of a _cloud native_ [Hazelcast](http://hazelcast.org/) deployment on Kubernetes.  When we say _cloud native_ we mean an application which understands that it is running within a cluster manager, and uses this cluster management infrastructure to help implement the application. In particular, in this instance, a custom Hazelcast ```bootstrapper``` is used to enable Hazelcast to dynamically discover Hazelcast nodes that have already joined the cluster.
+
+Any topology changes are communicated and handled by Hazelcast nodes themselves.
+
+This document also attempts to describe the core components of Kubernetes, _Pods_, _Services_ and _Replication Controllers_.
+
+### Prerequisites
+This example assumes that you have a Kubernetes cluster installed and running, and that you have installed the ```kubectl``` command line tool somewhere in your path.  Please see the [getting started](https://github.com/GoogleCloudPlatform/kubernetes/tree/master/docs/getting-started-guides) for installation instructions for your platform.
+
+
+
+The v1beta3 API is not enabled by default. The kube-apiserver process needs to run with the --runtime_config=api/v1beta3 argument. Use the following command to enable it:
+```sh
+$sudo sed -i 's|KUBE_API_ARGS="|KUBE_API_ARGS="--runtime_config=api/v1beta3|' /etc/kubernetes/apiserver
+
+
+```
+
+
+
+### quickstart
+For those of you who are impatient, here is the summary of the commands we ran in this tutorial.
+
+```sh
+# create a single hazelcast node
+kubectl create -f hazelcast-controller.yaml
+
+# create a service to track all hazelcast nodes
+kubectl create -f hazelcast-service.yaml
+
+# scale up to 2 nodes
+kubectl resize rc hazelcast --replicas=2
+
+# validate the cluster
+docker exec <container-id> nodetool status
+
+# scale up to 4 nodes
+kubectl resize rc hazelcast --replicas=4
+
+# Examine the status again by checking a node’s log and you should see the 4 members connected.
+$ kubectl log 16b2beab-94a1-11e4-8a8b-42010af0e23e hazelcast
