<p>I recently installed <code>microk8s</code>, and enabled helm3 and dns addons on microk8s.
Deployment from <code>stable/chart</code> works fine but any deployment from <code>bitnami/chart</code> fails.</p>
<p><strong>OS:</strong> Ubuntu 20.04.1 LTS -- microk8s:  1.19/stable</p>
<pre><code>microk8s.helm3 install my-release bitnami/jenkins
=&gt; Error: parse error at (jenkins/charts/common/templates/_secrets.tpl:84): function &quot;lookup&quot; not defined

microk8s.helm3 install my-release bitnami/magento
=&gt; Error: parse error at (magento/charts/elasticsearch/charts/common/templates/_secrets.tpl:84): function &quot;lookup&quot; not defined
</code></pre>

<p>There was a bug reported <a href="https://github.com/jenkinsci/helm-charts/issues/193" rel="noreferrer">here</a> and <a href="https://github.com/helm/helm/issues/7955" rel="noreferrer">here</a> which was caused by the conditional inclusion of <code>lookup</code> into the function map.</p>
<p>A fix for it was merged <a href="https://github.com/helm/helm/pull/7969" rel="noreferrer">here</a> and is now available from Helm version 3.2.0.</p>
<p>So, in order to fix this issue you should update your Helm to version 3.2.0 or newer.</p>
