Note: The deploy stack script has been superceeded with cft-deploy, which you can get from pypi via pip install cftdeploy. deploy_stack.rb is not being updated.
Deploying Cloudformation templates via the CLI is a complex process that lack repeatability. Typing out long command lines, and then having to execute other commands either before or after the stack runs results in lots of custom scripting. Rather than go down that route, I created a tool that takes a yaml manifest file that allows you to specify all the details around your stack deployment in one data-driven place.
