AWS CloudFormation Custom Resource

Demo of CloudFormation Custom Resources.

The code does not create an actual resource, but it responds to CloudFormation as though it had.

It logs a lot to CloudWatch so you can see the payloads from CloudFormation and what is sent to the S3 bucket (as a reply to CloudFormation).

Prerequisites

• SAM CLI installed.
• Java 8 or higher.
• A recent Maven version.

How to run

First create an S3 bucket with some name. Then edit package-and-deploy.sh.tmp and replace with that name.
Then rename package-and-deploy.sh.tmp to package-and-deploy.sh and run sh package-and-deploy.sh
