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 ``` --- # Agent Instructions This documentation is published with GitBook.

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/aws-cdk-files.md?ask=&goal= ``` `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.
