Quick Start

Minimal working example:

# terraform/main.tf
terraform {
  required_version = ">= 1.0"

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

  # Remote state configuration
  backend "s3" {
    bucket         = "terraform-state-prod"
    key            = "prod/terraform.tfstate"
    region         = "us-east-1"
    encrypt        = true
    dynamodb_table = "terraform-locks"
  }
}

provider "aws" {
  region = var.aws_region

  default_tags {
// ... (see reference guides for full implementation)

Best Practices

✅ DO

Use remote state (S3, Terraform Cloud)
Implement state locking (DynamoDB)
Organize code into modules
Use workspaces for environments
Apply tags consistently
Use variables for flexibility
Implement code review before apply
Keep sensitive data in separate variable files

❌ DON'T

Store state files locally in git
Use hardcoded values
Mix environments in single state
Skip terraform plan review
Use root module for everything
Store secrets in code
Disable state locking
