Using Ansible/Jinja macros to generate CloudFormation templates

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.
