Terraform AWS
Provision and manage AWS infrastructure with Terraform.
Provider Configuration
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
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
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
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
