Debugging lambda locally using cdk not sam

AWS CDK provides great features for developers. Using CDK deveolper can manage not only total infrastructure but also security, codepipeline, ...

However I recently struggling something. I used to debug lambda using SAM for local debugging. I know how to set up CDK environment, and debug CDK application itself. But I can't figure out how to debug lambda application inside CDK.

Can anyone help me?

Solution

  • You can use SAM and CDK together as described here. In particular:

    1. Run your AWS CDK app and create a AWS CloudFormation template

      cdk synth --no-staging > template.yaml

    2. Find the logical ID for your Lambda function in template.yaml. It will look like MyFunction12345678, where 12345678 represents an 8-character unique ID that the AWS CDK generates for all resources. The line right after it should look like: Type: AWS::Lambda::Function

    3. Run the function by executing:

      sam local invoke MyFunction12345678 --no-event
