About The Project
cf2tf is a CLI tool that attempts to convert Cloudformation to Terraform. We say attempt because it's not really possible to make the conversion with 100% accuracy (currently) because of several reasons mostly around converting a Map value in Cloudformation to the correct value in HCL.
Getting Started
Prerequisites
Cloudformation 2 Terraform requires python >= 3.8
Installation
cf2tf is available as an easy to install pip package.
pip install cf2tf
If you are a Homebrew user, can you install via brew:
$ brew install cf2tf
Usage
To convert a template to terraform.
cf2tf my_template.yaml
This above command will dump all the terraform resources to stdout. You might want to save the results:
cf2tf my_template.yaml > main.tf
If you prefer to have each resource in its own file then:
cf2tf my_template.yaml -o some_dir
If some_dir doesn't exist, then it will be created for you. Then each resource type will be saved to a specific file (variables.tf, outputs.tf etc.).
Roadmap
- Better conversion of Cloudformation Maps to Terraform (Maps, Block and json)
- Allow overides for specific resources
- Handle more advanced Cloudformation parameter types like SSM/Secrets manager
- Better handling of Recources/Properties that failed conversion
- Only download files needed, not entire terraform source code (200MB)
See the open issues for a list of proposed features (and known issues).
