# Elastic-stack Helm Chart

This chart installs an elasticsearch cluster with kibana and logstash by default.
You can optionally disable logstash and install Fluentd if you prefer. It also optionally installs filebeat, nginx-ldapauth-proxy and elasticsearch-curator.

## Prerequisites Details

* Kubernetes 1.8+
* PV dynamic provisioning support on the underlying infrastructure

## Chart Details
This chart will do the following:

* Implemented a dynamically scalable elasticsearch cluster using Kubernetes StatefulSets/Deployments
* Multi-role deployment: master, client (coordinating) and data nodes
* Statefulset Supports scaling down without degrading the cluster

## Installing the Chart

To install the chart with the release name `my-release`:

```bash
$ helm install --name my-release stable/elastic-stack
```

## Deleting the Charts

Delete the Helm deployment as normal

```
$ helm delete my-release
```

Deletion of the StatefulSet doesn't cascade to deleting associated PVCs. To delete them:

```
$ kubectl delete pvc -l release=my-release,component=data
```
