<p>I wanted to bring up zookeeper using <code>helm install .</code>, but it says <code>Error: release &lt;servicename&gt; failed: services "zookeeper" already exists</code>. I don't see anything if I execute <code>helm list</code>too. Before installing the service, I checked using <code>helm list</code> if it already exists, and it doesn't.</p>

<p>How to check the reason for failure? </p>

<p>I think that the simplest solution is to <strong>add the <code>--debug</code> flag for the installation command</strong>:</p>
<pre><code>helm install chart my-chart --debug
</code></pre>
<p>Or if you prefer:</p>
<pre><code>helm  upgrade --install chart my-chart --debug
</code></pre>
<p>It displays all the resources which are created one by one and also related errors which occured during installation.</p>
