Set value in dependency of Helm chart : <p>I want to use the <a href="https://github.com/helm/charts/tree/master/stable/postgresql" rel="noreferrer">postgresql chart</a> as a requirements for my Helm chart.</p>

<p>My <code>requirements.yaml</code> file hence looks like this:</p>

<pre><code>dependencies:
  - name: "postgresql"
    version: "3.10.0"
    repository: "@stable"
</code></pre>

<p>In the postgreSQL Helm chart I now want to set the username with the property <code>postgresqlUsername</code> (see <a href="https://github.com/helm/charts/tree/master/stable/postgresql" rel="noreferrer">https://github.com/helm/charts/tree/master/stable/postgresql</a> for all properties).</p>

<p>Where do I have to specify this property in my project so that it gets propagated to the postgreSQL dependency?</p>
