Define infrastructure resources using programming constructs and provision them using HashiCorp Terraform

CDK for Terraform

This experimental repository contains software which is still being developed and in the alpha testing stage. It is not ready for production use.

CDK (Cloud Development Kit) for Terraform allows developers to use familiar programming languages to define cloud infrastructure and provision it through HashiCorp Terraform.

Overview

The CDK for Terraform project helps users define infrastructure resources using supported programming languages and generates a Terraform configuration in JSON. Users can then use the Terraform or the CDK for Terraform CLI to deploy the application.

The project uses AWS CDK constructs to define applications.

The CDK for Terraform project includes two packages:

• cdktf-cli - A CLI that allows users to run commands to initialize, import, and synthesize CDK for Terraform applications.
• cdktf - A library for defining Terraform resources using programming constructs.

The project currently supports TypeScript, Python, and Java.
