Introduction

A demo application illustrating how to create a Python Lambda function with a function URL using LocalStack. Lambda function URLs provide a dedicated HTTP(S) endpoint for invoking a Lambda function directly without an API Gateway.

Prerequisites

• A valid LocalStack for AWS license. Your license provides a LOCALSTACK_AUTH_TOKEN to activate LocalStack.
• Docker
• localstack CLI
• awslocal CLI
• Python 3

Check prerequisites

make check

Installation

make install

Start LocalStack

export LOCALSTACK_AUTH_TOKEN=<your-auth-token>
make start

Run the application

make run

The script:

• Packages the Lambda function with its dependencies.
• Creates the Lambda function in LocalStack.
• Configures a function URL with no authentication.
