nginx-acm: prototype nginx-lambda-gateway integration

[shawnhankim]

As a Product Manager,

I want customers to use NGINX Lambda gateway to securely expose their services as API.

Because customers who are running their services on Serverless platform are increasing, as the customers don’t want to manage the application server infrastructure. AWS Lambda is popular choice for AWS users which helps customers to run their services developed in the different programming languages (Go, Node.JS, Python, Java). There are increasing asks from customers to protect the services hosted in AWS Lambda.

As a Backend Engineer,

I want to save time for designing the Lambda integration with NGINX-ACM. The prototyping is one of ways to quickly implement a minimal viable product and determine based on the demo between PMs and SWEs which solution would be better among several approaches. So I can avoid redesigning entire architectures if there is any big mistakes of architecture after completing design and implementation.

AC:

• Inestigation
  • How to customize Lambda errors
  • Some customers expects HTTP headers and URIs to be passed in the body before sent to Lambda service.
• Implement an API to publish a Lambda policy to the API gateway
• Set up manually nginx-lambda-gateway.js and nginx-aws-signature.js in the data plane.
• Implement sample serverless functions.
• Demo environment between NMS-ACM, API-Gateway, nginx-lambda-gateway.js and serverless functions
• Suggest use cases and API schema to determine if the draft idea is convenient between UX and BE.

Misc.

• No test codes required
