<p>I have a need to use variables inside of <code>values.yaml</code> file:</p>

<pre><code>app:
    version: 1.0

my_app1:
    tag: {{ .app.version }} &lt;- version taken from appVersion. In my case tag == version
</code></pre>

<p>Any help will be really appreciated.</p>

<pre><code>app:
    version: 1.0

my_app1:
    tag:  {{ .Values.app.version }}

{{ .Values.app | first | default .Values.app.version }}
</code></pre>

<p>You can also try this <code>EDIT - 2</code></p>

<pre><code>{{- range $key, $value := .Values.app }}
       {{ $key }}: {{ $value }}
{{- end }}
</code></pre>
