# Helm charts

How to test Helm charts with Snyk IaC using the CLI

You scan a Helm chart by rendering the Helm templates into Kubernetes manifest files and then scanning these using the Snyk CLI `snyk iac` command.

For example, if you have a Helm Project located in a `./helm` directory, you would run the following command to output the templated files into a directory called `./output`:

{% tabs %}
{% tab title="macOS/Linux/Unix" %}

```
helm template ./helm --output-dir ./output
snyk iac test ./output
```

{% endtab %}

{% tab title="Windows PowerShell" %}

```
helm template .\helm\ --output-dir .\output\
snyk iac test .\output\
```

{% endtab %}
{% endtabs %}

For Unix-based terminals, you can also pipe the output of `helm template` directly into a single file:

```
helm template ./helm > output.yaml
snyk iac test output.yaml
```

The Snyk CLI cannot read from standard input at this time; Snyk is working on this feature.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.snyk.io/developer-tools/snyk-cli/scan-and-maintain-projects-using-the-cli/snyk-cli-for-iac/test-your-iac-files/helm-charts.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
