Terraform AWS

Provision and manage AWS infrastructure with Terraform.

Provider Configuration

hcl

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.0"
    }
  }
  
  backend "s3" {
    bucket = "terraform-state"
    key    = "prod/terraform.tfstate"
    region = "us-east-1"
  }
}

provider "aws" {
  region = var.region
  
  default_tags {
    tags = {
      Environment = var.environment
      ManagedBy   = "terraform"
    }
  }
}

Example Resources

hcl

resource "aws_vpc" "main" {
  cidr_block           = "10.0.0.0/16"
  enable_dns_hostnames = true
  
  tags = { Name = "main-vpc" }
}

resource "aws_instance" "web" {
  ami           = data.aws_ami.amazon_linux.id
  instance_type = "t3.micro"
  subnet_id     = aws_subnet.public.id
  
  tags = { Name = "web-server" }
}

Modules

hcl

module "vpc" {
  source = "terraform-aws-modules/vpc/aws"
  
  name = "my-vpc"
  cidr = "10.0.0.0/16"
  
  azs             = ["us-east-1a", "us-east-1b"]
  private_subnets = ["10.0.1.0/24", "10.0.2.0/24"]
  public_subnets  = ["10.0.101.0/24", "10.0.102.0/24"]
  
  enable_nat_gateway = true
}

Commands

bash

terraform init
terraform plan -out=plan.tfplan
terraform apply plan.tfplan
terraform destroy

Best Practices

Use remote state with locking
Implement module structure
Use workspaces or separate states per environment
Pin provider versions
Use data sources for AMIs
