terraform-aws-networking-data-only

Returns descriptive information about an Amazon VPC

Purpose

This module is considered to be a data-only module. Given the name of a VPC and an optional set of availability zones, this module returns information about a VPC, such as public and private subnets, the VPC ID, etc. See the outputs file for which data is returned from this module. This module is useful for workspaces that require such information without declaring repetitive data sources in your Terraform configurations.

Usage

The following example creates a security group and an application load balancer.

provider "aws" {}

module "networking" {
  source = "github.com/mongodb-devprod-infrastructure/terraform-aws-networking-data-only"

  vpc_name = "tutorial-vpc"
}

resource "aws_security_group" "this" {
  ingress = [
    {
      cidr_blocks = ["0.0.0.0/0"]
      from_port   = 443
      protocol    = "TCP"
      to_port     = 443
    }
  ]

  vpc_id = module.networking.vpc_id
}

resource "aws_lb" "this" {
  internal           = false
  load_balancer_type = "application"
  security_groups    = [aws_security_group.this.id]
  subnets            = module.networking.public_subnets
}
