<p>When I try to install a chart with helm:</p>

<pre><code>helm install stable/nginx-ingress --name my-nginx
</code></pre>

<p>I get the error: </p>

<blockquote>
  <p>Error: unknown flag: --name</p>
</blockquote>

<p>But I see the above command format in many documentations. </p>

<p>Version: </p>

<blockquote>
  <p>version.BuildInfo{Version:"v3.0.0-beta.3",
  GitCommit:"5cb923eecbe80d1ad76399aee234717c11931d9a",
  GitTreeState:"clean", GoVersion:"go1.12.9"}</p>
</blockquote>

<p>Platform: Windows 10 64</p>

<p>What could be the reason?</p>

<p>In Helm v3, the release name is now mandatory as part of the commmand, see <code>helm install --help</code>:</p>

<blockquote>
  <p>Usage:<br>
    helm install [NAME] [CHART] [flags]</p>
</blockquote>

<p><strong>Your command should be</strong>:</p>

<p><code>helm install my-nginx stable/nginx-ingress</code></p>

<hr>

<p>Furthermore, Helm will not auto-generate names for releases anymore. If you want the "old behavior", you can use the <code>--generate-name</code> flag. e.g:</p>

<p><code>helm install --generate-name stable/nginx-ingress</code></p>

<p>The v3 docs are available at <a href="https://v3.helm.sh/docs/" rel="noreferrer">https://v3.helm.sh/docs/</a>, but as it is a beta version, the docs will not be accurate for a while. It's better to rely on the CLI <code>--help</code>, that is auto-generated by Go/<a href="https://github.com/spf13/cobra" rel="noreferrer">Cobra</a>.</p>
