tjmcewan / aws_route53_cleaner_instructions.md
Last active August 29, 2015 14:27
Want to delete a lot of old hosted zones on Route53? This should take the pain away.

AWS Route53 Hosted Zone Cleaner

Why?

My org buys lots of domains and configure lots of records on AWS. Removing them is a pain though; you have to remove each record set before you can remove the hosted zone. This makes it much more straightforward.

Feel free to use this; but you're on your own. I am not responsible if you break something.

Setup

You'll need ruby/ruby-gems and your AWS API credentials.
