<p>Is it possible to use helm value in value, for example:</p>

<pre><code>db:
  addr: acid-keycloak-db
  user: kcadmin
  secret: {{ user }}.{{ addr }}.credentials.postgresql.acid.zalan.do  
</code></pre>

<p>the output should be: </p>

<pre><code>db:
  addr: acid-keycloak-db
  user: kcadmin
  secret: kcadmin.acid-keycloak-db.credentials.postgresql.acid.zalan.do   
</code></pre>

<p>values.yaml</p>

<pre><code>db:
  addr: acid-keycloak-db
  user: kcadmin
  secret: "{{ .Values.db.user }}.{{ .Values.db.addr }}.credentials.postgresql.acid.zalan.do"
</code></pre>

<p>In .yaml file where the secret will be used</p>

<pre><code>{{tpl .Values.db.secret . }}
</code></pre>
