serverless-plugin-nested-stacks

Nested stacks for the Serverless Framework!

Installation

Run npm install in your Serverless project.

$ npm install serverless-aws-nested-stacks --save-dev

Intro

Write your nested stacks as regular cloudformation and easily integrate them with the Serverless Framework!

This plugin handles:

• Adding the appropriate AWS::Cloudformation::Stack type resources to the generated sls cloudformation template.
• Uploading your nested stacks to your designated S3 deployment bucket.

• custom.nested-stacks.stacks.id - (Required) The logical ID of the nested stack resource.
