The AWS Serverless Application Model (SAM) is a framework on top of CloudFormation to quickly develop Cloud Applications with a focus on serverless services such as S3, Lambda, API Gateway, Step Functions and more.
AWS SAM CLI for LocalStack
To deploy SAM applications on LocalStack you can use samlocal, a wrapper for the AWS SAM CLI.
pip to install
samlocal as a Python library on your machine:
$ pip install aws-sam-cli-local
samlocal command has the exact same usage as the underlying

samlocal deploy the operations will be executed against the LocalStack endpoints (

samlocal when following the AWS tutorial.
