AWS Cloud Formation deployment CLI
Project description
Senza is a command line tool for generating and executing AWS Cloud Formation templates in a sane way. It supports Cloud Formation templates as YAML input and adds own ‘components’ on top. Components are predefined Cloud Formation snippets that are easy to configure and generate all the boilerplate JSON that is required by Cloud Formation.
