VPC Terraform Module

This Terraform module creates a Virtual Private Cloud (VPC) in AWS using the terraform-aws-modules/vpc/aws module.

Usage

1. Create a new Terraform configuration file (e.g., main.tf) and define the VPC module:

   module "vpc" {
     source  = "terraform-aws-modules/vpc/aws"
     version = "5.4.0"
   
     // Details
     name            = local.name
     cidr            = var.vpc_cidr_block
     azs             = var.vpc_availability_zones
     public_subnets  = var.vpc_public_subnets
     private_subnets = var.vpc_private_subnets
   
     // Database
     database_subnets                   = var.vpc_database_subnets
     create_database_subnet_group       = var.vpc_create_database_subnet_group
     create_database_subnet_route_table = var.vpc_create_database_subnet_route_table
   
     // NAT
     enable_nat_gateway = var.vpc_enable_nat_gateway
     single_nat_gateway = var.vpc_single_nat_gateway
   
     // VPC DNS
     enable_dns_hostnames = true
     enable_dns_support   = true
   
     // Tags
     tags     = local.tags
     vpc_tags = local.tags
   
     public_subnet_tags = {
       Type = "Public"
     }
     private_subnet_tags = {
       Type = "Private"
     }
     database_subnet_tags = {
       Type = "Private Datbase"
     }
   
     // For Public Subnet Launched Instances
     map_public_ip_on_launch = true
   }

2. Run terraform init and terraform apply to create the VPC.

3. Configure remote state in your Terraform configuration file for managing the state of your infrastructure.

State Storage

The state of this VPC Terraform module is stored in an S3 bucket. This allows for easier management and collaboration when deploying an EKS cluster, as the state can be accessed remotely.
