Cloudformation Batman - cleaning up the crime of abandoned stacks
Batman scours your AWS stack for villianous stacks and using genius intellect, physical prowess, martial arts abilities, detective skills, science and technology, vast wealth, intimidation, and indomitable will keeps the cloudy street safe and clean.
If you want to keep a stack safe from being killed by Batman add a Batman
tag to your cloudformation stack ({Key:'Batman'}
), no need to have any content.
Batman inspect the tags on your cloudformation stacks to determine what to shut down, specifically looking for the tag{Key: 'slice', Value: 'anything-other-than-master'}
Batman can also receive a bat signal (commonly known as a Github webhook) to delete stacks. Suggested usage is to receive a webhook when a branch is deleted so Batman can cleanup.
