carica-cfn-tools 1.4

Tools to manage CloudFormation stack configuration

Simple command line tools to create and update CloudFormation stacks that make it easy to version-control both your templates and stack configurations in one place. Supports a few proprietary transforms useful for dynamically merging a manually maintained template with a generated template (for example, sam.json from “chalice package”) that contains resources you’d like to include in your main template.

Development

The vinstall script uses virtualenv to prepare a Python environment useful for development, so you don’t have to build and install carica-cfn-tools to be able to run and test it.

1. Run ./vinstall

2. Activate the virtualenv by running . ./venv/bin/activate

3. The console_scripts listed in setup.py are now in your path, so you can simply run them like:

   carica-cfn ...
