AWS Lambda Functions

Simple AWS Lambda Functions written in Go to facilitate my exploration of building applications in AWS

This project is part of one big project where I research how to build infrastructure in AWS for 2-tier application (and application as well, of course) :

1. Terraform contains all the terraform code to deploy required infra & application code
2. Simple Web GUI contains code for simple Web GUI to bridge the gap between user and Lambda functions
3. Lambda functions (this project) contain code for 3 Lambda functions that replicate simple backend functions
   1. return_ip - returns IP address of the Lambda function
   2. fetch_go_versions - returns JSON with recent 5 Go versions
   3. custom_auth - custom Lambda authorizer (only supports payload format version 1.0) that controls access to functions 1 & 2 when calling via API Gateway
   4. custom_auth_v2 - custom Lambda authorizer (only supports payload format version 2.0) that controls access to functions 1 & 2 when calling via API Gateway

Notes

1. This repo uses Github Action to build & push compiled Golang into S3 and from there Functions are deployed with Terraform
2. Lambda function gets build by Golang version 1.20
