Generating terrform code from exisiting aws resources

AWS2Terraform

This project is intended to extract resources created in AWS as Terraform resources.

I implemented the CLI using Spring Shell project and JCommander library.

The goal of the current project is an extract program for Terraform resources, and will be developed in the future towards generating tfvar and tfstates according to standardized Terraform code.

Run

java -jar terraform-generator-shell-[version].jar
