    This example provides API endpoints which are executed by AWS Lambda using Python. The example sets up up two Lambda-backed API Gateways: an API Gateway V1 (REST) and an API Gateway V2 (HTTP). AWS provides some information on the differences between these two API Gateway types: Announcing HTTP APIs for Amazon API Gateway and API Gateway V2 FAQs

    This sample uses the following AWS products:

    Prerequisites

    1. Install Pulumi

    2. Create a new stack:

      $ pulumi stack init aws-py-apigateway-lambda-serverless
      
    3. Set the AWS region:

      $ pulumi config set aws:region us-east-2
      

    Deploy the App

    1. Run pulumi up to preview and deploy changes:

    2. To view the runtime logs of the Lambda function, use the pulumi logs command. To get a log stream, use pulumi logs --follow.

    Test the Endpoints

    Use a HTTP tool like curl or httpie (pip3 install httpie) to query the API Gateway endpoints using the Pulumi stack outputs.

    Example using curl:

    curl $(pulumi stack output apigateway-rest-endpoint)
    curl $(pulumi stack output apigatewayv2-http-endpoint)
    

    Example using httpie:

    http $(pulumi stack output apigateway-rest-endpoint)
    http $(pulumi stack output apigatewayv2-http-endpoint)
    

    Output should include "Cheers from AWS Lambda!!".

    Clean Up

    1. Run pulumi destroy to tear down all resources.

    2. To delete the stack itself, run pulumi stack rm. Note that this command deletes all deployment history from the Pulumi console.

    Summary

    In this tutorial, you built a lambda-backed API on AWS using API Gateway, lambda functions, and Pulumi. This serverless solution is highly scaleable, resilient, and stateless.
