        # Terraform EC2 NAT Host Module

[AWS Doc about VPC NAT Instance](https://docs.aws.amazon.com/vpc/latest/userguide/VPC_NAT_Instance.html#NATInstance)

## Usage

```hcl

module "nat_instance" {

    source    = "hazelops/ec2-nat/aws"

    version   = "~> 3.0"

    enabled                 = var.nat_gateway_enabled ? false : true

    env                     = var.env

    vpc_id                  = module.vpc.vpc_id

    allowed_cidr_blocks     = [module.vpc.vpc_cidr_block]

    public_subnets          = module.vpc.public_subnets

    private_route_table_id  = module.vpc.private_route_table_ids[0]

    ec2_key_pair_name       = var.ec2_key_pair_name

}

```
