Terraformer-AWS-Project

This project offers a guide and scripts for using Terraformer to import your existing AWS infrastructure into Terraform configuration files. Terraformer is a CLI tool that generates tf/json and tfstate files based on existing infrastructure (reverse Terraform). This process allows for a seamless transition to managing your infrastructure as code using Terraform

Prerequisites 🧰

✅ AWS CLI: Make sure you have the AWS CLI installed and configured with the necessary access rights to your AWS resources.
✅ Terraform: Ensure you have Terraform installed on your machine. Terraform is required to manage the generated files and apply changes.

Installation 🐾

Installing Terraformer💫

1. After installing Terraform, Download exe file for the required cloud provider from here. In our case, it is windows amd64.
   source: https://github.com/GoogleCloudPlatform/terraformer/tree/master?tab=readme-ov-file#installation

2. Add the path to the Terraformer executable file to the environmental variables' "Path" variable on your local system.

3. Create a folder📂(AWS to Terraform) and within it, create a file named "version.tf"📄 to install the plugins required for your platform. For example, in our case we need plugins for the AWS Cloud so versions.tf should contain:

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = ">= 5.41.0"
    }
  }
  required_version = ">= 0.13"
}

or git clone this repo

git clone https://github.com/al3v/Terraformer-AWS-Project.git

4. Configure AWS CLI

 aws configure

5. Navigate into the folder and ensure that the version.tf file is present

6. Run 🖱️

 terraform init

7. Run 🖱️( Here are alternative commands you can use)
   
   

 terraformer import aws --resources=vpc,subnet --regions=eu-west-1

8. To import all resources

terraformer import aws --resources="*" --regions=eu-central-1

To exclude some resources:

terraformer import aws --resources="*" --excludes=identitystore --regions=eu-central-1

Result ✨

In your folder(AWS to Terraform), you will find a subfolder named generated where you can locate separate subfolders for your "vpc.tf" and "subnet.tf" files.
