Example of using terraform-aws-modules/vpc/aws module with Terragrunt

README.md

This is an example of how to use Terraform AWS registry modules with Terragrunt.

Notes:

1. source has to be full git URL and not Terraform Registry open issue #311
2. File main_providers.tf is named so, because it will be copied to another local directory and merged with module's code. If such file exists in the module already then it will overwrite the one provided by the module.

main_providers.tf

provider "aws" {
  region = "eu-west-1"
}

terraform {
  backend "s3" {}
}

terraform.tfvars

terragrunt = {
  terraform {
    source = "git::[email protected]:terraform-aws-modules/terraform-aws-vpc.git?ref=v1.0.4"
  }
}

# MODULE PARAMETERS
name = "my-vpc"

cidr = "10.212.0.0/20"

azs                 = ["eu-west-1a", "eu-west-1b", "eu-west-1c"]
private_subnets     = ["10.212.1.0/24", "10.212.2.0/24", "10.212.3.0/24"]
public_subnets      = ["10.212.11.0/24", "10.212.12.0/24", "10.212.13.0/24"]
database_subnets    = ["10.212.5.0/24", "10.212.6.0/24", "10.212.7.0/24"]

create_database_subnet_group = true

enable_dns_support = true
enable_dns_hostnames = true

enable_nat_gateway = true
single_nat_gateway = false

Where are you storing the main_providers.tf file?
