<p>I am trying to install a helm chart on an air gapped system. The chart should be pulling an image from a private docker registry and deploy to the kubernetes cluster (both also on the air gapped system). My chart passed linting but when I try to install it, I keep seeing the error:</p>
<pre><code>$ helm install my-mongodb . --debug
install.go:172: [debug] Original chart version: &quot;&quot;

<p>Helm is installed:</p>
<pre><code>$ helm version

<p>My docker image successfully runs in a docker container, so I'm fairly confident the image isn't the issue. What am I doing wrong?</p>
<p>EDIT: I am running the helm install command at: /opt/helm-charts/my-mongodb
This is the location of the Charts.yaml file. The file structure is:</p>
<pre><code>my-mongodb
 - Chart.yaml
 - values.schema.json
 - values.yaml
 - charts
 - templates
   - deployment.yaml
   - _helpers.tpl
   - hpa.yaml
   - ingress.yaml
   - NOTES.txt
   - serviceaccount.yaml
   - service.yaml
   - tests
     - test-connection.yaml
</code></pre>
<p>This chart was created with the command: helm create my-mongodb and then I edited the Charts.yaml, values.yaml and deployment.yaml files</p>
<p>Here is the deployment.yaml file as well:</p>

<p>It is probably a version compatibility issue. Helm v3.3.x is not compatible with Kubernetes v1.5.2.</p>
<p>As per <a href="https://helm.sh/docs/topics/version_skew/#supported-version-skew" rel="nofollow noreferrer">Supported Version Skew</a>:</p>
<blockquote>
<p>When a new version of Helm is released, it is compiled against a
particular minor version of Kubernetes. For example, Helm 3.0.0
interacts with Kubernetes using the Kubernetes 1.16.2 client, so it is
compatible with Kubernetes 1.16.</p>
<pre><code>|---------------------|--------------------------------------|
|      Helm Version   |     Supported Kubernetes Versions    |
|---------------------|--------------------------------------|
|         3.4.x       |           1.19.x - 1.16.x            |
|         3.3.x       |           1.18.x - 1.15.x            |
|         3.2.x       |           1.18.x - 1.15.x            |
|---------------------|--------------------------------------|
</code></pre>
</blockquote>
<p>More than that, you are using <code>apiVersion: apps/v1</code> for your Deployment version. This API version was introduced on Kubernetes <a href="https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.9.md#workloads-api-appsv1" rel="nofollow noreferrer">v1.9.0</a>.</p>
