vpc terraform module

This module is deprecated and terraform-aws-modules/terraform-aws-vpc module published on the Terraform registry should be used instead.

This repository will not have active support any more.

---

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
• create_database_subnet_group - Controls, if should database subnet group be created
• 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_classiclink - should be true if you want to use ClassicLink within the VPC
• enable_classiclink_dns_support - should be true if you want to use private DNS within the classiclinks
• enable_nat_gateway - should be true if you want to provision NAT Gateways
• single_nat_gateway - should be true if you want to provision a single shared NAT Gateway across all of your private networks
• enable_s3_endpoint - should be true if you want to provision an S3 endpoint within the VPC
• enable_dynamodb_endpoint - should be true if you want to provision a DynamoDB 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
• default_network_acl_id - VPC default network ACL id
• vpc_endpoint_s3_id - VPC Endpoint ID for S3
• vpc_endpoint_dynamodb_id - VPC Endpoint ID for Dynamodb

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