AWS SAM CLI adds BuildKit support for AWS Lambda functions packaged as container images

AWS Serverless Application Model Command Line Interface (SAM CLI) now supports BuildKit for building container images from Dockerfiles, enabling faster, more efficient container image builds for Lambda functions packaged as container images. SAM CLI is a command-line tool for building, testing, debugging, and packaging serverless applications locally before deploying to AWS Cloud. Developers packaging Lambda functions as container images often need advanced build features provided by BuildKit to optimize their images for production.
