serverless-s3-cleaner

Serverless Framework plugin that empties an S3 bucket before removing a deployed stack. Replacement for serverless-s3-remover which is no longer maintained.

Installation

npm install serverless-s3-cleaner --save-dev

Compatibility with Serverless Framework

Version 1.0.2 is compatible with Serverless Framework v3, but it uses the legacy logging interface. Version 2.0.0 and later uses the new logging interface.

serverless-s3-cleaner	Serverless Framework
≤ v1.0.1	v1.x, v2.x
v1.0.2	v1.x, v2.x, v3.x
≥ v2.0.0	v3.x

Usage

Add the following to your serverless.yml:

plugins:
  - serverless-s3-cleaner

custom:
  serverless-s3-cleaner:
    # (optional) Whether to prompt before emptying a bucket. Default is 'false'.
    prompt: false

    # Names of buckets to remove before a stack is removed, or via 'sls s3remove' command
    buckets:
      - bucketName1
      - bucketName2

    # (optional) Buckets to remove before a stack is deployed.
    bucketsToCleanOnDeploy:
      - oldBucketName

When removing a Serverless Framework stack, this plugin automatically empties the buckets listed under buckets option.

When deploying a Serverless Framework stack, this plugin automatically empties the buckets listed under bucketsToCleanOnDeploy option. Use this when renaming or removing a bucket (put here the old bucket name) to avoid deployment errors when CloudFormation tries to remove the old bucket.

You can also empty a bucket explicitly by running:

sls s3remove

Versioning

Buckets with versioning enabled are supported. When emptying a bucket, all object versions and delete markers are deleted.

IAM Permissions

The plugin requires the following permissions to be given to the role that Serverless runs under, for all the affected buckets:

• s3:ListBucket
• s3:ListBucketVersions
• s3:DeleteObject
• s3:DeleteObjectVersion
