vpc terraform module

A terraform module to provide a VPC in AWS.

Module Input Variables

name - vpc name
cidr - vpc cidr
public_subnets - list of public subnet cidrs
private_subnets - list of private subnet cidrs
azs - list of AZs in which to distribute subnets
enable_dns_hostnames - should be true if you want to use private DNS within the VPC
enable_dns_support - should be true if you want to use private DNS within the VPC
enable_nat_gateway - should be true if you want to provision NAT Gateways for each of your private networks
map_public_ip_on_launch - should be false if you do not want to auto-assign public IP on launch
private_propagating_vgws - list of VGWs the private route table should propagate
public_propagating_vgws - list of VGWs the public route table should propagate
tags - dictionary of tags that will be added to resources created by the module

It's generally preferable to keep public_subnets, private_subnets, and azs to lists of the same length.

This module optionally creates NAT Gateways in each public subnet and sets them as the default gateways for the corresponding private subnets.

Usage

module "vpc" {
  source = "github.com/terraform-community-modules/tf_aws_vpc"

  name = "my-vpc"

  cidr = "10.0.0.0/16"
  private_subnets = ["10.0.1.0/24", "10.0.2.0/24", "10.0.3.0/24"]
  public_subnets  = ["10.0.101.0/24", "10.0.102.0/24", "10.0.103.0/24"]

  enable_nat_gateway = "true"

  azs      = ["us-west-2a", "us-west-2b", "us-west-2c"]

  tags {
    "Terraform" = "true"
    "Environment" = "${var.environment}"
  }
}

For Terraform version older than 0.7.0 use ref=v1.0.0: source = "github.com/terraform-community-modules/tf_aws_vpc?ref=v1.0.0"

Outputs

vpc_id - does what it says on the tin
private_subnets - list of private subnet ids
public_subnets - list of public subnet ids
public_route_table_ids - list of public route table ids
private_route_table_ids - list of private route table ids
default_security_group_id - VPC default security group id string
nat_eips - list of Elastic IP ids (if any are provisioned)
igw_id - Internet Gateway id string

NOTE: previous versions of this module returned a single string as a route table ID, while this version returns a list.
