vpc terraform module

NOTE: THIS IS A FORK, IGNORE THIS. I WILL DELETE THIS REPO SHORTLY.

A terraform module to provide a VPC in AWS.

Module Input Variables

name - name to be used on all the resources created by the module
cidr - the CIDR block for the VPC
instance_tenancy - tenancy option for instances launched into the VPC
public_subnets - list of public subnet cidrs
private_subnets - list of private subnet cidrs
database_subnets - list of private RDS subnet cidrs
elasticache_subnets - list of private Elasticache 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
enable_s3_endpoint - should be true if you want to provision an S3 endpoint within the VPC
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
public_subnet_tags - dictionary of tags that will be added to public subnets created by the module
private_subnet_tags - dictionary of tags that will be added to private subnets created by the module
database_subnet_tags - dictionary of tags that will be added to database subnets created by the module
elasticache_subnet_tags - dictionary of tags that will be added to elasticache subnets 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 (one per availability zone) 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
database_subnets - list of database subnets ids
database_subnet_group - db subnet group name
elasticache_subnets - list of elasticache subnets ids
elasticache_subnet_group - elasticache subnet group name
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)
nat_eips_public_ips - list of NAT gateways' public Elastic IP's (if any are provisioned)
natgw_ids - list of NAT gateway ids
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.
