forest-fire

This is a little command-line tool with an ill-advised name, to easily tear down CloudFormation stacks which have outputs that other stacks depend on. In the AWS Console this is rather annoying, since you have to manually chase up dependencies.

This tool simply interrogates the aws-cli tool about the stack you're trying to delete, finds out its outputs, and checks whether any currently-active stacks are importing them. The output is a dependency tree, which trivially tells us the order of deletion for it to succeed. If you're feeling adventurous, you may also let forest-fire do the actual deletion for you.

Installation

Prerequisites

You'll need the following installed and available to be able to use this software:

• Haskell Stack
• AWS CLI interface

Instructions

tba

Usage

If you simply run the tool without arguments, it'll print usage information. Here's the down-low, however.

Find out what depends on a stack

stack exec forest-fire -- "kubernetes-dynamic-91acf0ef-lifecycle"

Perform the deletions if you're satisfied with the tree

stack exec forest-fire -- "kubernetes-dynamic-91acf0ef-lifecycle" --delete

Thanks Redbubble, i totally should've been doing other things instead of shaving this yak.
