Generating CloudFormation Templates from YAML Dictionaries

The security group and Network ACLs parts of CloudFormation templates can be difficult to read. This template containing Jinja macros converts easier-to-read YAML dictionaries of security group and NACL rules into JSON.

Here ais a generic macro template and some example files showing how to use it.

• cloudformation.macros.j2 - the macros
• cf_vars.yml - YAML dictionaly of security groups and NACLs, including some complex rules for both
• test.template.j2 - a simple CloudFormation template that uses the macro file
• cf_test.yml - a simple Ansible playbook that generates CloudFormation JSON from thr previous file.

"""
This module implements an Ansible plugin that is triggered at the start of a playbook.

The plugin dynamically generates a tag for each role. Each tag has the same name as its role.
The advantage of this is that it saves you some boilerplate, because you don't have to wrap
all tasks of a role in an additional block and assign a tag to that.
Additionally, it works automatically when you add new roles to your playbook.

Usage is exactly the same as without this plugin:
