Delete non-empty S3 bucket

Purpose

Show how to use the serverless-s3-remover plugin to remove non-empty S3 buckets.

Why

Limitations with AWS S3 + AWS CloudFormation. You must empty the S3 bucket then delete it. This is restrictive, if you run sls remove then sls deploy, but put objects into your bucket. It will throw errors saying the s3 bucket already exists.

Steps

• npm install --save-dev serverless-s3-remover

• Add plugins section

plugins:
    - serverless-s3-remover

• Add bucket names to empty + delete

custom:
    base: ${self:service}-${self:provider.stage}
    s3:
        bucketA:
            name: ${self:custom.base}-my-awesome-bucket
        bucketB:
            name: ${self:custom.base}-my-other-cool-bucket
    remover:
        buckets:
            - ${self:custom.s3.bucketA.name}     # bucket name
            - ${self:custom.s3.bucketB.name}

• Deploy - sls deploy -v

• Add file

$ echo "hello" > hello.txt
$ aws s3 cp hello.txt s3://s3-remover-dev-my-awesome-bucket --profile serverlessguru
$ aws s3 cp hello.txt s3://s3-remover-dev-my-other-cool-bucket --profile serverlessguru

upload: ./hello.txt to s3://s3-remover-dev-my-awesome-bucket/hello.txt
upload: ./hello.txt to s3://s3-remover-dev-my-other-cool-bucket/hello.txt
