Configuration, parameterization, and environmental partitioning of AWS CloudFormation stacks.

Murk is a tool intended to simplify the configuration, management, and partitioning of your AWS CloudFormation environment. It offers:

• A simple CLI for creating and destroying CloudFormation stacks by name, with some simple rules for locating templates.
• A DSL for specifying the parameter values you wish to supply when creating stacks from templates.
• A mechanism for specifying different 'environments' (e.g. production, dev, qa), and the stacks that should be created within them.

A DSL for generating CloudFormation templates themselves. Murk assumes you've already authored your CloudFormation templates by hand, or generated them using another 3rd party tool.

• Ruby 2.2.x
• AWS SDK for Ruby v2
• Configured AWS SDK credentials
