📦 Overview

The Terraform AWS Resource Master is a “main” module that ties together multiple submodules to provision a complete AWS environment. Out of the box it can create:

• VPC with public/private subnets, NAT gateways, route tables
• EC2 instances with customizable AMIs, instance types, security groups
• RDS instances (MySQL/Postgres) with configurable storage & backups
• S3 buckets for app storage and logging
• Plus optional submodules for CloudWatch alarms, DynamoDB tables, Lambda functions, and more

⚙️ Prerequisites

• AWS account with IAM permissions for networking, compute, storage, database
• Terraform v1.0+ installed locally
• AWS CLI configured (aws configure) or environment variables set

🚀 Quick Start

Create a root main.tf and reference the module:

module "resource_master" {
  source      = "Pradipbabar/resource-master/aws/"
  enable_vpc  = true
  enable_ec2  = true
  enable_rds  = true
  enable_s3   = true
  # enable_cloudwatch = true
  # enable_dynamodb  = true
}

Then run:

terraform init
terraform apply

To tear down:

terraform destroy

🔗 Submodules

• VPC: Public/private subnets, NAT, route tables
• EC2: Auto-scaled or fixed EC2 fleets
• RDS: MySQL/Postgres with backups & multi-AZ
• S3: Primary buckets + logging buckets
• CloudWatch: Alarms on CPU, disk, network
• DynamoDB: On-demand or provisioned tables
• …and more via additional modules (Lambda, IAM roles, etc.)

📤 Outputs

Each submodule exports useful values for chaining or reference:

• VPC ID, subnet IDs, route table IDs
• EC2 instance IDs, public IPs
• RDS endpoint, port
• S3 bucket ARNs
• CloudWatch alarm ARNs

Check each submodule’s README for the full list.

🔮 Future Enhancements

• Support for private DNS zones & Transit Gateway
• Built-in Bastion Host & Session Manager setup
• Terraform Cloud & state backends examples
• Automated “blue/green” RDS upgrades
