AWS Infrastructure Creation with OpenTofu This repository contains an Infrastructure as Code (IaC) project that uses OpenTofu to deploy a basic infrastructure on Amazon Web Services (AWS). The main goal is to create a Virtual Private Cloud (VPC) and a public subnet using a modular and automated approach.

What I did Deployed a VPC: Configured a VPC with a CIDR block of 10.0.0.0/16 and the tag opentofu-demo-vpc.

Added a public subnet: Created a subnet within the VPC with a CIDR block of 10.0.1.0/24 and the tag opentofu-demo-public-subnet.

Automated with OpenTofu: Used OpenTofu to define, plan, and apply the infrastructure in the AWS us-east-2 region.

Structured the project: Organized files with modules, variables, and outputs to facilitate reuse and management.

Project Structure main.tf: Defines the AWS provider and calls the VPC module with customizable variables.

variables.tf: Contains variables (region, vpc_cidr, subnet_cidr, project_name) with default values.

outputs.tf: Exposes the IDs of the VPC and subnet (vpc_id, subnet_id) generated.

modules/vpc/main.tf: Implements the aws_vpc and aws_subnet resources with their configurations.

.gitignore: Ignores sensitive files such as .tfstate and .terraform/ to protect state and providers.

Requirements OpenTofu: Installed locally (version 1.10.6 or higher).

AWS CLI or credentials: Set environment variables AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and AWS_REGION with an IAM user that has permissions (e.g., AdministratorAccess).

Git: To version and push the project to GitHub.

How to Use Clone the repository:

bash git clone https://github.com/rodriveracr/opentofu.git cd opentofu Configure AWS credentials: Obtain an Access Key ID and Secret Access Key from the AWS console (IAM > Users). In the terminal, set:

bash $env:AWS_ACCESS_KEY_ID = "your-access-key" $env:AWS_SECRET_ACCESS_KEY = "your-secret-key" $env:AWS_REGION = "us-east-2" Initialize OpenTofu:

bash tofu init This installs the required providers and modules.

Review the plan:

bash tofu plan Shows the resources to be created (VPC and subnet).

Apply the infrastructure:

bash tofu apply Confirm with yes to create the resources. The IDs will be shown as outputs.

Verify in AWS: Go to the AWS console and check the VPC and subnet in the us-east-2 region.

Destroy resources (optional):

bash tofu destroy Confirm with yes to delete everything.

Results VPC ID: vpc-0f3d72c8b3d353eae

Subnet ID: subnet-0c4bfed0c0a5ae9c5 These resources are active in AWS and were created with the corresponding tags.

Contributions This project is a starting point. You can:

Add more resources (e.g., internet gateway, route table) by editing modules/vpc/main.tf.

Adjust variables in variables.tf to customize the infrastructure.

Share improvements in this repository.

Security Notes Do not upload access keys to GitHub.

Use environment variables or a remote backend for state.

Monitor costs in the AWS console, although this project uses the Free Tier.

Thanks for exploring this OpenTofu project!
