serverless-plugin-custom-roles

A Serverless plugin that makes creation of per function IAM roles easier. It mimics serverless behavior, but creates separate roles for each function instead of a shared one. If you want to create per function roles without using this plugin, you are responsible for providing the corresponding permissions for your function logs and stream events and need to repeat the same permissions from function to function.
