<p>I am trying to deploy <strong>elastic-search in kubernetes</strong> with local drive volume  but  I get the following error, can you please correct me.
<strong>using ubuntu 16.04
kubernetes v1.11.0
Docker version 17.03.2-ce</strong>
Getting error 'unknown field hostPath' Kubernetes Elasticsearch using with local volume</p>

<pre><code>error: error validating "es-d.yaml": error validating data: ValidationError(StatefulSet.spec.template.spec.containers[1]): unknown field "hostPath" in io.k8s.api.core.v1.Container; if you choose to ignore these errors, turn validation off with --validate=false

<p>You have the wrong structure. <code>volumes</code> must be on the same level as <code>containers</code>, <code>initContainers</code>.</p>
