Terraform AWS EC2 Module Project

This Terraform project demonstrates the use of modules to create and manage AWS EC2 instances across different environments (development, staging, and production).

Features

• Modular design for reusable EC2 instance configurations
• Support for multiple environments (dev, stage, prod)
• Centralized variable management through terraform.tfvars

Prerequisites

• AWS CLI configured with appropriate credentials
• Terraform installed (version 0.12 or later)
• Basic understanding of AWS EC2 service

Usage

1. Initialize Terraform:

terraform init

2. Select workspace for your environment:

terraform workspace select dev    # For development
terraform workspace select stage  # For staging
terraform workspace select prod   # For production

3. Review the planned changes:

terraform plan

4. Apply the configuration:

terraform apply

Module Configuration

The EC2 instance module can be configured through variables in terraform.tfvars. Example configuration:

instance_type = "t2.micro"
ami_id        = "ami-xxxxx"

State Management

This project uses local state files organized by environment in the terraform.tfstate.d directory. Each environment (dev, stage, prod) maintains its own state file.
