+A Kolla Demo using Heat
+=======================
+
+By default, the launch script will spawn 3 Nova instances on a Neutron
+network created from the tools/init-runonce script. Edit the VM\_COUNT
+parameter in the launch script if you would like to spawn a different
+amount of Nova instances. Edit the IMAGE\_FLAVOR if you would like to
+launch images using a flavor other than m1.tiny.
+
+Then run the script:
+
+::
+
+    $ ./launch

+Reliable, Scalable Redis on Kubernetes
+--------------------------------------
+
+The following document describes the deployment of a reliable,
+multi-node Redis on Kubernetes. It deploys a master with replicated
+slaves, as well as replicated redis sentinels which are use for health
+checking and failover.
+
+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.
+
+A note for the impatient
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is a somewhat long tutorial. If you want to jump straight to the
+"do it now" commands, please see the `tl; dr <#tl-dr>`__ at the end.
+
+Turning up an initial master/sentinel pod.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+is a
+`*Pod* <https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/user-guide/pods.md>`__.
+A Pod is one or more containers that *must* be scheduled onto the same
+host. All containers in a pod share a network namespace, and may
+optionally share mounted volumes.
+
+We will used the shared network namespace to bootstrap our Redis
+cluster. In particular, the very first sentinel needs to know how to
+find the master (subsequent sentinels just ask the first sentinel).
+Because all containers in a Pod share a network namespace, the sentinel
+can simply look at ``$(hostname -i):6379``.
+
+Here is the config for the initial master and sentinel pod:
+`redis-master.yaml <redis-master.yaml>`__
+
+Create this master as follows:
+
+.. code:: sh
+
+    kubectl create -f examples/redis/v1beta3/redis-master.yaml
+
+Turning up a sentinel service
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In Kubernetes a *Service* describes a set of Pods that perform the same
+task. For example, the set of nodes in a Cassandra cluster, or even the
+single node we created above. An important use for a Service is to
+create a load balancer which distributes traffic across members of the
+set. But a *Service* can also be used as a standing query which makes a
+dynamically changing set of Pods (or the single Pod we've already
+created) available via the Kubernetes API.
+
+In Redis, we will use a Kubernetes Service to provide a discoverable
+endpoints for the Redis sentinels in the cluster. From the sentinels
+Redis clients can find the master, and then the slaves and other
+relevant info for the cluster. This enables new members to join the
+cluster when failures occur.
+
+Here is the definition of the sentinel
+service:\ `redis-sentinel-service.yaml <redis-sentinel-service.yaml>`__
+
+Create this service:
+
+.. code:: sh
+
+    kubectl create -f examples/redis/v1beta3/redis-sentinel-service.yaml
+
+Turning up replicated redis servers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+So far, what we have done is pretty manual, and not very fault-tolerant.
+If the ``redis-master`` pod that we previously created is destroyed for
+some reason (e.g. a machine dying) our Redis service goes away with it.
+
+In Kubernetes a *Replication Controller* is responsible for replicating
+sets of identical pods. Like a *Service* it has a selector query which
+identifies the members of it's set. Unlike a *Service* it also has a
+desired number of replicas, and it will create or delete *Pods* to
+ensure that the number of *Pods* matches up with it's desired state.
+
+Replication Controllers will "adopt" existing pods that match their
+selector query, so let's create a Replication Controller with a single
+replica to adopt our existing Redis server.
+`redis-controller.yaml <redis-controller.yaml>`__
+
+The bulk of this controller config is actually identical to the
+redis-master pod definition above. It forms the template or "cookie
+cutter" that defines what it means to be a member of this set.
+
+Create this controller:
+
+.. code:: sh
+
+    kubectl create -f examples/redis/v1beta3/redis-controller.yaml
+
+We'll do the same thing for the sentinel. Here is the controller
+config:\ `redis-sentinel-controller.yaml <redis-sentinel-controller.yaml>`__
+
+We create it as follows:
+
+.. code:: sh
+
+    kubectl create -f examples/redis/v1beta3/redis-sentinel-controller.yaml
+
+Resize our replicated pods
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Initially creating those pods didn't actually do anything, since we only
+asked for one sentinel and one redis server, and they already existed,
+nothing changed. Now we will add more replicas:
+
+.. code:: sh
+
+    kubectl resize rc redis --replicas=3
+
+.. code:: sh
+
+    kubectl resize rc redis-sentinel --replicas=3
+
+This will create two additional replicas of the redis server and two
+additional replicas of the redis sentinel.
+
+Unlike our original redis-master pod, these pods exist independently,
+and they use the ``redis-sentinel-service`` that we defined above to
+discover and join the cluster.
+
+Delete our manual pod
+~~~~~~~~~~~~~~~~~~~~~
+
+The final step in the cluster turn up is to delete the original
+redis-master pod that we created manually. While it was useful for
+bootstrapping discovery in the cluster, we really don't want the
+lifespan of our sentinel to be tied to the lifespan of one of our redis
+servers, and now that we have a successful, replicated redis sentinel
+service up and running, the binding is unnecessary.
+
+Delete the master as follows:
+
+.. code:: sh
+
+    kubectl delete pods redis-master
+
+Now let's take a close look at what happens after this pod is deleted.
+There are three things that happen:
+
+1. The redis replication controller notices that its desired state is 3
+   replicas, but there are currently only 2 replicas, and so it creates
+   a new redis server to bring the replica count back up to 3
+2. The redis-sentinel replication controller likewise notices the
+   missing sentinel, and also creates a new sentinel.
+3. The redis sentinels themselves, realize that the master has
+   disappeared from the cluster, and begin the election procedure for
+   selecting a new master. They perform this election and selection, and
+   chose one of the existing redis server replicas to be the new master.
+
+Conclusion
+~~~~~~~~~~
+
+At this point we now have a reliable, scalable Redis installation. By
+resizing the replication controller for redis servers, we can increase
+or decrease the number of read-slaves in our cluster. Likewise, if
+failures occur, the redis-sentinels will perform master election and
+select a new master.
+
+tl; dr
+~~~~~~
+
+For those of you who are impatient, here is the summary of commands we
+ran in this tutorial
+
+.. code:: sh
+
+    # Create a bootstrap master
+    kubectl create -f examples/redis/v1beta3/redis-master.yaml
+
+    # Create a service to track the sentinels
+    kubectl create -f examples/redis/v1beta3/redis-sentinel-service.yaml
+
+    # Create a replication controller for redis servers
+    kubectl create -f examples/redis/v1beta3/redis-controller.yaml
+
+    # Create a replication controller for redis sentinels
+    kubectl create -f examples/redis/v1beta3/redis-sentinel-controller.yaml
+
+    # Resize both replication controllers
+    kubectl resize rc redis --replicas=3
+    kubectl resize rc redis-sentinel --replicas=3
+
+    # Delete the original master pod
+    kubectl delete pods redis-master
+
