CloudFormation example for API Gateway integration to Lambda function

Template that will create the following:

• API Gateway endpoint:
  • A single root method, accepting POST requests only with Lambda proxy integration to a function.
• In-line Lambda function echoing back requesting users IP address to API Gateway requests:
  • IAM role for Lambda allowing CloudWatch logs access.
  • Permissions for Lambda that allow API Gateway endpoint to successfully invoke function.
• CloudWatch logs group for Lambda, with 90 day log retention.

After standing up the template, you should be able to curl a POST request to the URL listed as the apiGatewayInvokeURL output value.
