+# Aerospike Helm Chart
+
+This is an implementation of Aerospike StatefulSet found here:
+
+ * https://github.com/aerospike/aerospike-kubernetes
+
+## Pre Requisites:
+
+* Kubernetes 1.5 with beta APIs enabled and support for statefulsets
+
+* PV support on underlying infrastructure (only if you are provisioning persistent volume).
+
+* Requires at least `v2.5.0` version of helm to support
+
+## StatefulSet Details
+
+* https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/
+
+## StatefulSet Caveats
+
+* https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#limitations
+
+## Chart Details
+
+This chart will do the following:
+
+* Implement a dynamically scalable Aerospike cluster using Kubernetes StatefulSets
+
+### Installing the Chart
+
+To install the chart with the release name `my-aerospike` using a dedicated namespace(recommended):
+
+```
+$ helm repo add incubator http://storage.googleapis.com/kubernetes-charts-incubator
+$ helm install --name my-aerospike --namespace aerospike incubator/aerospike
+```
+
+The chart can be customized using the following configurable parameters:
+
+| Parameter               | Description                        | Default                                                    |
+| ----------------------- | ---------------------------------- | ---------------------------------------------------------- |
+| `image.repository`        | Aerospike Container image name            | `aerospike/aerospike-server`                               |
+| `image.tag`               | Aerospike Container image tag             | `3.14.1.2`                                                 |
+| `image.pullPolicy`        | Aerospike Container pull policy           | `Always`                                                   |
+| `replicaCount`            | Aerospike Brokers                         | `1`                                                        |
+| `persistentVolume`        | Configuration of persistent volumes for storage-engine   | `{}`                                        |
+| `confFile`                | Aerospike config filename. This file should be included in the chart path.        | `aerospike.conf`   |
+| `resources`               | Aerospike resource requests and limits    | `{}`                                                       |
+| `nodeSelector`            | Labels for pod assignment                 | `{}`                                                       |
+| `terminationGracePeriodSeconds`   | This is the time kubernetes will wait before forcefully terminating the container   | `30`     |
+
+Specify parameters using `--set key=value[,key=value]` argument to `helm install`
+
+Alternatively a YAML file that specifies the values for the parameters can be provided like this:
+
+```bash
+$ helm install --name my-aerospike -f values.yaml incubator/aerospike
+```
+
+### Conf files for Aerospike
+
+There is one conf file added to each Aerospike release. This conf file can be replaced with a custom file and updating the `confFile` value. 
+
+If you modify the `aerospike.conf` (and you use more than 1 replica), you want to add the `#REPLACE_THIS_LINE_WITH_MESH_CONFIG` comment to the config file (see the default conf file). This will update your mesh to connect each replica.
+
+## Known Limitations
+
+* Persistent volume claims tested only on GCP
+* Aerospike cluster is not accessible via an external endpoint

+The Aerospike can be accessed via port 3000 on the following DNS name from within your cluster:

+You can connect to aeropike in your local machine using port-forwarding:
