VPC

Introduction

This module creates a VPC structure, with a set of private subnets in listed availability zones, routing through a NAT gateway/public subnet for external connectivity. Additionally, will setup AWS VPC peering with specified targets.

Inputs

Name	Description	Type	Default	Required
project_name	Name of associated project, for resource tagging	string	nil	yes
vpc_cidr	CIDR block for new VPC	string	"10.0.0.0/16"	yes
subnets	List of private subnets to create within new VPC	list	["10.0.1.0/24", "10.0.2.0/24", "10.0.3.0/24"]	yes
subnet_az	List of availability zones, one per subnet	list	["us-east-1a", "us-east-1b", "us-east-1c"]	yes
public_cidr	CIDR block for "public" subnet to house Internet gateway	string	"10.0.254.0/24"	yes
peer_vpc_cidrs	List of VPC CIDR blocks with which to establish peering	list	nil	no
peer_vpc_ids	List of VPC resource IDs with which to establish peering	list	nil	no
peer_vpc_regions	List of regions within which peer VPCs exist	list	nil	no

Outputs

Name	Description	Type
vpc_id	AWS resource ID of new VPC	string
vpc_arn	AWS ARN of new VPC	string
subnet_id	List of new private subnet IDs	list
subnet_arn	List of new private subnet ARNs	list

Example

provider "aws" {
  region  = "us-east-1"
  version = "~> 2.31.0"
}

module "aws_vpc" {
  source = "github.com/ParallelTheory/tf_vpc"

  project_name = "example_vpc"
  vpc_cidr     = "10.0.0.0/16"
  subnets      = ["10.0.1.0/24", "10.0.2.0/24", "10.0.3.0/24"]
  subnet_az    = ["us-east-1a", "us-east-1b", "us-east-1c"]
  public_cidr  = "10.0.254.0/28"

  peer_vpc_cidrs   = ["10.1.0.0/24"]
  peer_vpc_ids     = ["vpc-27cda542"]
  peer_vpc_regions = ["us-east-1"]
}
