This is the AWS CDK v2 Developer Guide. The older CDK v1 entered maintenance on June 1, 2022 and ended support on June 1, 2023.
The AWS SAM CLI provides support for building Lambda functions and layers defined in your AWS CDK application with sam build.
For Lambda functions that use zip artifacts, run cdk synth before you run
sam local commands. sam build isn't required.
If your AWS CDK application uses functions with the image type, run cdk synth
and then run sam build before you run sam local commands. When you
run sam build, AWS SAM doesn't build Lambda functions or layers that use
runtime-specific constructs, for example, NodejsFunction. sam build doesn't support bundled
assets.
Example
Running the following command from the AWS CDK project root directory builds the application.
$sam build -t./cdk.out/CdkSamExampleStack.template.json
