serverless-default-aws-resource-attributes

This plugin allows you to set default attributes a given CloudFormation resource should have based on type.

This plugin affects resources generated by Serverless. For example, any default attributes defined for S3 buckets will be applied to the Serverless-generated ServerlessDeploymentBucket bucket. You are, however, able to exclude Serverless-generated resources using Exclude: (see below).

Usage

Install the plugin:

npm install -D serverless-default-aws-resource-attributes

Register the plugin in serverless.yml:
