<p>You can retrieve your previous <code>--set</code> arguments cleanly, with <code>helm get values &lt;release-name&gt;</code>. If you direct this into a file (<code>helm get values &lt;release-name&gt; &gt; pulsar.yml</code>), you can safely
pass this file through <code>-f</code>. Thus <code>helm upgrade &lt;release-name&gt; pulsar -f pulsar.yaml</code>. This safely replaces the behavior of <code>--reuse-values</code>.</p>
