# Elastic Cloud on Kubernetes (ECK) Helm Chart

This Helm Chart basically wraps the [Elastic Cloud on Kubernetes (ECK)](https://www.elastic.co/guide/en/cloud-on-k8s/1.0/k8s-overview.html) CRD to make it accessible for Helm only setups avoiding `kubectl` commands.

## Installing the CRD Chart

```sh
helm repo add eck git+https://github.com/8gears/elastic-cloud-on-kubernetes-crd
```

```sh
helm install eck/eck-crd
```

## Installing the CR Chart

```sh
helm repo add eck git+https://github.com/8gears/elastic-cloud-on-kubernetes-crd
```

```sh
helm install eck/eck-crd
```

## ECK CRD - Custom Resource Definition

There are no configuration options for the CRD only for the instances.
