Code for my talk at PyATL on 2018-10-11 on Lambda, Python and API Gateway

Lambda and Python for PyATL, Oct 2018

Purpose:

Build a fully functioning Lambda + AWS API Gateway integration, from end to end.

Exposes one endpoint: /counts/<CountName> and two methods on that endpoint: GET and POST. Future work could include implementing DELETE as well (exercise for the reader).

Directory map:

• 00_pre_req - Terraform for the prebuilt IAM rights for hello_world lambda
• 01_hello_world - Python code for hello_world lambda function
• 02_increment_counter - Python code to increment a counter in dynamodb, and tf code to deploy
• 03_api_gateway - Final piece of terraform, does API GW. Will be symlinked into the 02 directory.
• 04_aws_serverless - TODO

URI Map:

/counts/<CountName>

• GET -> Retrieve current count for <CountName>
• POST -> increment current count, retrieve new count for <CountName>
