AWS SAM CLI Now Supports Finch

AWS Serverless Application Model Command Line Interface (SAM CLI) now supports Finch as an alternative to Docker for local development and testing of serverless applications. This gives developers greater flexibility in choosing their preferred local development environment when working with SAM CLI to build and test their serverless applications.

What to do

  • Choose between Docker and Finch for local development with SAM CLI.
  • Use SAM CLI commands with Finch for local invocation, API endpoint testing, and debugging.
  • Set Finch as your preferred container tool for SAM CLI.
