Terraform & Infrastructure as Code

Quick Start

Main Configuration

terraform {
  required_version = ">= 1.0"
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.0"
    }
  }
}

provider "aws" {
  region = "us-east-1"
}

resource "aws_instance" "example" {
  ami           = "ami-0c55b159cbfafe1f0"
  instance_type = "t2.micro"

  tags = {
    Name = "example"
  }
}

resource "aws_s3_bucket" "example" {
  bucket = "my-bucket"
}

output "instance_ip" {
  value = aws_instance.example.public_ip
}

Key Concepts

• Resources: Infrastructure components
• Variables: Input values
• Outputs: Return values
• State: Track infrastructure
• Modules: Reusable components
• Providers: Infrastructure platforms

Commands

terraform init          # Initialize
terraform plan          # Preview changes
terraform apply         # Apply changes
terraform destroy       # Destroy infrastructure
terraform state list    # View state

Best Practices

✅ Version control everything ✅ Use modules ✅ Use variables ✅ Implement remote state ✅ Use workspaces ✅ Follow naming conventions ✅ Document infrastructure
