The Terraform CDK is a relatively new project, presently in community preview, that provides a nice extension to "programatically" create infrastructure with Terraform.
Some developers prefer to use a familiar programming language to define their infrastructure. This allows them to use the same language constructs and tools they are familiar with for other development tasks. They can also use all of the features and libraries available to fully featured programming languages to develop complex infrastructure projects. Additionally the CDK provides us with a harness to integrate external services and data with Terraform. Also by using your programming language of choice, you can take advantage of the features and development workflows you are familiar with. For example, when working with Python, you can use IDE features such as IntelliSense in Visual Studio Code.
This repository contains a few example use cases on how to leverage the CDK.
All of these examples utilize AWS, so you'll need to generate and set your credentials accordingly.
In order to use CDKTF, you will need Terraform and Node.js. These examples are based upon Python.
Use existing code example:
- Clone git respo
- cd into project and example folder
pipenv installcdktf synthcdktf deploycdktf destroy
Start a blank project from scratch:
- mkdir
- cd into directory
- Execute
cdktf init --template="python" --localNote: the-localoption is for locally managed state file, otherwise you will be prompted for TF Cloud state management. - For Python based projects install the CDKTF provider; i.e.
pipenv install cdktf-cdktf-provider-aws - Edit the
main.pyfile with the desired coding and CDK resources. - Generate TF plan and valid code:
cdktf synth - Provision infrastructure
cdktf deploy - Destroy infrastructure
cdktf destroy
