Setting Environment Variables on GCE (kubernetes)
<p>Sorry for the noob question but from <a href="https://github.com/kubernetes/kubernetes/blob/release-1.1/docs/getting-started-guides/logging-elasticsearch.md" rel="noreferrer">https://github.com/kubernetes/kubernetes/blob/release-1.1/docs/getting-started-guides/logging-elasticsearch.md</a>
it says:   </p>

<blockquote>
  <p>To use Elasticsearch and Kibana for cluster logging you should set the
  following environment variable as shown below:</p>
</blockquote>

<pre><code>KUBE_LOGGING_DESTINATION=elasticsearch
</code></pre>

<p>Where and how do I set this Env Var ? I was thinking that I should use       </p>

<pre><code>gcloud container clusters create   
</code></pre>

<p>and pass the options there but there is no options...</p>
