This Action for AWS CDK allow you to build your python layer in an amazon linux 2 docker image (so you will get native libs optimized for your lambda runtime environment), and allow you to run the cdk command you needs (cdk synth, npx cdk deploy, ...) after you build your python layer.

Currently supports CDK apps using Typescript cdk, and python projects

*This Github Action is specifically based on the Amazon Linux distribution to ensure Python dependencies, compiled to C, are functional when deployed to AWS Lambda.

An example workflow for building a layer zip archive, and synthesizing an AWS CloudFormation template for your app using cdk synth.
