<p>I have installed <a href="https://www.katacoda.com/courses/kubernetes/helm-package-manager" rel="noreferrer"><code>redis</code></a>. The default given name to me is <code>plinking-narwhal</code>. Now I would like to install a service with my assigned name. But first I want to remove the existing one. I had tried deleting them without success.</p>

joe
<p>You probably need:</p>

<pre><code>$ helm delete redis
</code></pre>

<p>or if you completely want to remove the release:</p>

<pre><code>$ helm delete redis --purge
</code></pre>

<p><code>stable/redis</code> is not allowed as an expression because of the slash(<code>/</code>)</p>

<p>If you'd like to see the name of the releases you can simply run:</p>

<pre><code>$ helm list -aq
</code></pre>
