# AWS CDK files

How to test AWS CDK files with Snyk IaC using the CLI

With Snyk Infrastructure as Code, you can test your configuration files with the CLI. You can scan the [Amazon Web Services Cloud Development Kit (AWS CDK)](https://aws.amazon.com/cdk/) with the Snyk CLI by generating a CloudFormation file using the CDK CLI.

Follow these steps to scan a CDK application:

**Navigate** to the directory that contains the application stack for which you want to generate the CloudFormation.

**Generate** the CloudFormation file.

```
cdk synth
```

This is displayed on your terminal as YAML output, and a JSON file is created in the `cdk.out` directory

**Scan** the JSON file using the following Snyk IaC CLI command, replacing `cdk.out/*.json` with the name of the application that you want to scan.

```
snyk iac test cdk.out/*.json
```

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

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

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
