fck-nat Terraform Module

A module to spin up a NAT instance running fck-nat in an AWS account.

Warning: Generally you should use a NAT gateway for production purposes. This module provides a very low cost solution for testing and development purposes.

Example Usage

module "nat-instance" {
  source                      = "ahodges22/terraform-aws-fck-nat"
  name                        = "dev"
  vpc_id                      = "vpc-xxxx"
  public_subnet               = "subnet-xxxx"
  private_subnets_cidr_blocks = ["10.10.1.1/24"]
  private_route_table_ids     = ["rtb-xxxx"]
}
