<p>I was following this <a href="https://towardsdatascience.com/kubernetesexecutor-for-airflow-e2155e0f909c" rel="noreferrer">blog post</a> and at this command, </p>

<p><code>helm upgrade --install airflow airflow/ \
    --namespace airflow \
    --values values.yaml</code></p>

<p>I got this error. 
<code>in airflow: chart metadata (Chart.yaml) missing</code> but I actually have the Chart.yaml file under <code>airflow/</code>. </p>

<pre class="lang-sh prettyprint-override"><code>$ ls
Chart.yaml      charts          requirements.yaml   tiller.yaml
Icon?           requirements.lock   templates       values.yaml
</code></pre>

<p>helm version &amp; kubectl pod below</p>

<pre><code>$ helm version

<p>Could someone help to fix it?</p>

<p>I also had the error with Airflow. I noticed that you have to respect the folder structure. This example will fail:</p>

<pre><code>./charts
  ./charts/airflow
  ./charts/template ---&gt; will produce the error 
</code></pre>

<p>While this folder structure will work:</p>

<pre><code>./charts
   ./charts/airflow 
   templates --&gt; will work
</code></pre>
