nginx-aws-signature: s3-gateway inteoperability implementation

[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 make sure the library of nginx-aws-signature is interoperable with nginx-s3-gateway prior to integrating with nginx-lambda-gateway. Because nginx-aws-signature is the common library which is refactored from nginx-s3-gateway, and nginx-aws-signature should work with new library of nginx-aws-signature. So it will save time for testing when integrating with nginx-lambda-gateway.

AC:

• Refactor nginx-s3-gateway by integrating with nginx-aws-signature.
• Refactor unit test of nginx-s3-gateway.
• Refactor integration test of nginx-s3-gateway.
• Refactor installation scripts for Docker containers.
