tf-mod-aws-vpc

Module description

Use the tf-mod-aws-vpc Terraform module to provision a VPC with Internet Gateway.

Project: %!s() : [%!s()] | [%!s()]

Introduction

The module provisions the following resources:

• An AWS VPC with default security group.
• A default AWS Internet Gateway (IGW) associated with the VPC created.

Usage

IMPORTANT: The master branch is used in source just as an example. In your code, do not pin to master because there may be breaking changes between releases. Instead pin to the release tag (e.g. ?ref=tags/x.y.z) of one of our latest releases.

The below values shown in the usage of this module are purely representative, please replace desired values as required.

  module "tf-mod-aws-vpc" {
    source         = "git::https://github.com:Callumccr/tf-mod-aws-vpc.git?ref=master"
    enabled        = true
    aws_account_id = "12345678910"
    aws_region     = "eu-west-1"
    cidr_block     = "10.0.0.0/16"
    tags           = {
                      "ABC" = "XYZ"
                      }
  }
