This is a basic Terraform project setup for AWS infrastructure management.

Prerequisites

1. Install Terraform: Download from terraform.io
2. AWS CLI: Install and configure with your credentials
3. AWS Account: Ensure you have appropriate permissions

Getting Started

1. Configure Variables

Copy the example variables file and customize it:

cp terraform.tfvars.example terraform.tfvars

Edit terraform.tfvars with your desired values.

2. Configure AWS Credentials

Make sure your AWS credentials are configured:

aws configure

Or set environment variables:

export AWS_ACCESS_KEY_ID="your-access-key"
export AWS_SECRET_ACCESS_KEY="your-secret-key"
export AWS_DEFAULT_REGION="us-west-2"

3. Initialize Terraform

terraform init

4. Plan the Deployment

terraform plan

5. Apply the Configuration

terraform apply

6. Destroy Resources (when done)

terraform destroy

What This Creates

This basic configuration creates:

• A VPC with DNS support
• An Internet Gateway
• A public subnet in the first available AZ
• Proper tagging for all resources

Customization

• Modify variables.tf to add new variables
• Update main.tf to add new resources
• Add new output values in outputs.tf
• Use modules for reusable components

Best Practices

• Always run terraform plan before apply
• Use version control for your Terraform code
• Keep sensitive data in terraform.tfvars (not committed to git)
• Use remote state for team collaboration
• Tag all resources consistently

Troubleshooting

• Ensure AWS credentials are properly configured
• Check that your AWS account has necessary permissions
• Verify the region and availability zones are correct
• Review Terraform logs for detailed error messages
