How to permanently delete versioned objects from S3

Seamus Abshere on

This is part of our cloud security and things that are obvious once you see them series. Duhh... safe!

Amazon's explanation of deleting a versioned object and the SDK documentation do not give an example of permanently deleting a versioned object. Here's how to do it:

require 'aws-sdk'

s3 =  
  region: 'us-east-1',
  access_key_id: ACCESS_KEY_ID,
  secret_access_key: SECRET_ACCESS_KEY
bucket = s3.bucket('my-versioned-bucket')

bucket.objects.each do |object_summary|  
  o = bucket.object object_summary.key
  # this is the secret: specify the version while deleting
  o.delete version_id: o.version_id

If you don't specify the version, you get a delete marker, which you can proceed to delete infinite times and it will not go away :)
