Intended Audience

pyplates are intended to be used with the Amazon Web Services CloudFormation service. If you're already a CloudFormation (CFN) user, chances are good that you've already come up with fun and interesting ways of generating valid CFN templates. pyplates are a way to make those templates while leveraging all of the power that the python environment has to offer.

What is a pyplate?

A pyplate is a class-based python representation of a JSON CloudFormation template and resources, with the goal of generating cloudformation templates based on input python templates (pyplates!) that reflect the cloudformation template hierarchy.

Features

• Allows for easy customization of templates at runtime, allowing one pyplate to describe all of your CFN Stack roles (production, testing, dev, staging, etc).
• Lets you put comments right in the template!
• Supports all required elements of a CFN template, such as Parameters, Resources, Outputs, etc.)
• Supports all intrinsic CFN functions, such as base64, get_att, ref, etc.
• Converts intuitiviely-written python dictionaries into JSON templates, without having to worry about nesting or order-of-operations issues.
