ring-lambda

A ring lambda handler with reitit routes.

It is designed to handle API Gateway proxied requests where the resource is defined like /dummy/{proxy+}.

The code for converting from api-gateway to ring request was borrowed from:

• https://wtfleming.github.io/blog/clojure-aws-lambda/
• https://sideshowcoder.com/2018/05/11/clojure-ring-api-gateway-lambda/

Dockerfile

1. Change the name of the project in project.clj (this will decide the name of the standalone jar)
2. Change the path of the standaalone jar in the Dockerfile
3. Change the classname and handler method in the Dockerfile
