# Use a local IaC custom rules bundle

{% hint style="info" %}
Where the examples show `bundle.tar.gz`, you can replace this with your bundle name. For example,`bundle-v1.0.0.tar.gz` or `./bundles/team-bundle.tar.gz`
{% endhint %}

In your Project folder, run the following command:

```
snyk iac test --rules=bundle.tar.gz
```

The configuration scan results now include issues from both the default Snyk rules and your custom rules. See [Understanding the IaC CLI test results](https://app.gitbook.com/s/IEEjSXQQu36y0vmFV8zf/snyk-cli/scan-and-maintain-projects-using-the-cli/snyk-cli-for-iac/understand-the-iac-cli-test-results).

To troubleshoot a local custom rules bundle, enable debug logs by running the command with the `--d` options:

```
snyk iac test --rules=bundle.tar.gz -d
```

Some possible problems include:

* Providing an incorrect path to the bundle or a path to a non-existent bundle. Ensure the path passed to the `--rules` option can be accessed from the current location. The error is

```
We were unable to extract the rules provided at: ./invalid/location/bundle.tar.gz
```

* Providing a corrupted or invalid bundle. Ensure you have generated your bundle by following the instructions in [Getting Started with the SDK](/scan-fix-and-prevent/scan-with-snyk/snyk-iac/current-iac-custom-rules/writing-rules-using-the-sdk.md). The error is

```
We were unable run the test. Please run the command again with the `-d` flag and contact support@snyk.io with the contents of the output.
```

If you have found a discrepancy that you cannot explain, [contact Snyk Support](https://support.snyk.io).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/scan-fix-and-prevent/scan-with-snyk/snyk-iac/current-iac-custom-rules/use-iac-custom-rules-with-cli/use-a-local-iac-custom-rules-bundle.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.
