Custom CloudFormation Resource
Custom resources are custom CloudFormation templates. Any valid JSON CloudFormation Template can be defined in this resource and Stackery will merge it with the template for the rest of the stack.
See AWS’s template reference for valid resources, type names, intrensic functions and pseduo parameters that are available for use.
Note: As this resource lets you create any resource available through CloudFormation, Stackery does not validate the CloudFormation template inside this resource.
