serverless-custom-buckets

Create and configure multiple custom s3 buckets

Purpose

When you create an S3 bucket as a resource in Serverless, it means the S3 bucket lifecycle is controlled by Cloud Formation. This could introduce a problem if you want to keep the bucket beyond the life of the Cloud Formation stack. This could also introduce a problem when you delete the Cloud Formation stack but fail to delete the S3 bucket. When you try and re-create the Cloud Formation stack, it would fail because the bucket already exists.

This plugin aims to solve the above problems by allowing you to create your custom bucket(s) if it doesn't exist, update the the bucket(s) if it exists, and optionally configure server-side encryption, versioning, public access, policy and cors.

Install

yarn add serverless-custom-buckets --dev

npm install serverless-custom-buckets --save-dev
