Terraform AWS VPC Module

This Terraform configuration sets up an AWS Virtual Private Cloud (VPC) with public and private subnets. It utilizes a module to manage VPC resources across different environments.

Files

• main.tf: Defines the AWS provider and resources for creating the VPC and subnets.
• variables.tf: Defines input variables used in the configuration.
• dev-vpc.tf: Configuration for the development environment using the tf-vpc module.
• prod-vpc.tf: Configuration for the production environment using the tf-vpc module.
• outputs.tf: Defines output values to be displayed after Terraform applies the configuration.

Usage

1. Set up AWS Provider: Ensure you have AWS credentials configured either through environment variables or AWS CLI configuration.

2. Adjust Variables (if necessary): Modify variables.tf to customize CIDR blocks or other parameters as needed.

3. Initialize Terraform: Run terraform init in the directory where these files are located to initialize Terraform and download necessary providers.

4. Review Plan: Run terraform plan to see the execution plan and ensure it matches your expectations.

5. Apply Changes: Run terraform apply to apply the configuration and create the AWS resources.

6. Destroy Resources: If needed, run terraform destroy to destroy the created AWS resources.

Modules

• tf-vpc: A module located in the ../modules directory is used to encapsulate the VPC creation logic. It accepts an environment parameter to distinguish between environments (DEV, PROD).

Outputs

• vpc-cidr-block: Outputs the CIDR block of the VPC created by the tf-vpc module.

Notes

• Ensure proper AWS IAM permissions are set for the AWS credentials used with Terraform.
• This configuration assumes AWS region us-east-1. Modify provider "aws" block in main.tf to change the region if necessary.
