opentofu-vpc

This is a Opentofu/Terraform module for creating AWS VPC using a standard pattern:

• Two public subnets
• Two private subnets
  • IPv4 egress via NAT gateway (extra cost)
  • IPv6 egress via egress-only internet gateway

Input variables

• basename: prefix or suffix to add to all resource names
• region: AWS region to create the VPC in
• manage_ipv4_nat_gateway: whether to create/manage the IPv4 NAT gateway for extra cost (boolean, defaults to false)
• vpc_cidr_block: CIDR block for the VPC
• primary_public_subnet_cidr_block: CIDR block for the primary public subnet
• secondary_public_subnet_cidr_block: CIDR block for the secondary public subnet
• primary_private_subnet_cidr_block: CIDR block for the primary private subnet
• secondary_private_subnet_cidr_block: CIDR block for the secondary private subnet

Output variables

• primary_private_subnet_id: ID of the primary private subnet
• secondary_private_subnet_id: ID of the secondary private subnet
• private_route_table_id: ID of the private subnet routing table
• primary_public_subnet_id: ID of the primary public subnet
• secondary_public_subnet_id: ID of the secondary public subnet
• public_route_table_id: ID of the public subnet routing table
• vpc_id: the ID of the VPC
• cidr_block: the CIDR block of the VPC

Example usage

module "acme-vpc" {
  source                              = <git-url>
  basename                            = "acme"
  region                              = "us-west-1"
  manage_ipv4_nat_gateway             = true
  vpc_cidr_block                      = "10.172.0.0/20"
  primary_public_subnet_cidr_block    = "10.172.0.0/24"
  secondary_public_subnet_cidr_block  = "10.172.1.0/24"
  primary_private_subnet_cidr_block   = "10.172.2.0/24"
  secondary_private_subnet_cidr_block = "10.172.3.0/24"
}
