Terraform module to connect two VPC’s from different AWS account.

We eat, drink, sleep and most importantly love DevOps. We are working towards strategies for standardizing architecture while ensuring security for the infrastructure. We are strong believer of the philosophy Bigger problems are always solved by breaking them into smaller manageable problems. Resonating with microservices architecture, it is considered best-practice to run database, cluster, storage in smaller connected yet manageable pieces within the infrastructure.

This module is basically combination of Terraform open source and includes automatation tests and examples. It also helps to create and improve your infrastructure with minimalistic code instead of maintaining the whole infrastructure code yourself.

We have fifty plus terraform modules. A few of them are comepleted and are available for open source usage while a few others are in progress.

Prerequisites

This module has a few dependencies:

• Terraform 1.x.x
• Go
• github.com/stretchr/testify/assert
• github.com/gruntwork-io/terratest/modules/terraform

Examples

IMPORTANT: Since the master branch used in source varies based on new modifications, we suggest that you use the release versions here.

Simple Example

Here are an example of how you can use this module in your inventory structure:

  module "vpc-peering" {
        source            = "clouddrove/multi-account-peering/aws"
        version           = "1.0.1"
        name              = "vpc-peering"
        environment       = "test"
        label_order       = ["environment", "name"]
        enable_peering    = true
        accepter_role_arn = "arn:aws:iam::XXXXXXXXXXXX:role/assume-role"
        accepter_region   = "eu-west-1"
        requestor_vpc_id  = "vpc-XXXXXXXXXXXXXX"
        acceptor_vpc_id   = "vpc-XXXXXXXXXXXXXX"
       }

Inputs

Name	Description	Type	Default	Required
accepter_region	The region of acceptor vpc.	string	n/a	yes
accepter_role_arn	The Role ARN of accepter AWS account.	string	""	no
acceptor_allow_remote_vpc_dns_resolution	Allow acceptor VPC to resolve public DNS hostnames to private IP addresses when queried from instances in the requestor VPC.	bool	true	no
acceptor_vpc_id	Acceptor VPC ID.	string	n/a	yes
attributes	Additional attributes (e.g. 1).	list(any)	[]	no
enable_peering	Set to false to prevent the module from creating or accessing any resources.	bool	false	no
environment	Environment (e.g. prod, dev, staging).	string	""	no
label_order	Label order, e.g. name,application.	list(any)	[]	no
managedby	ManagedBy, eg 'CloudDrove'	string	"[e-mail]"	no
name	Name (e.g. app or cluster).	string	""	no
profile_name	Name of aws profile.	string	null	no
repository	Terraform current module repo	string	"https://github.com/clouddrove/terraform-aws-multi-account-peering"	no
requestor_allow_remote_vpc_dns_resolution	Allow requestor VPC to resolve public DNS hostnames to private IP addresses when queried from instances in the acceptor VPC.	bool	true	no
requestor_vpc_id	Requestor VPC ID.	string	n/a	yes
tags	Additional tags (e.g. map(BusinessUnit,XYZ).	map(string)	{}	no

Outputs

Name	Description
accept_status	The status of the VPC peering connection request.
connection_id	VPC peering connection ID.
tags	A mapping of tags to assign to the resource.

Testing

In this module testing is performed with terratest and it creates a small piece of infrastructure, matches the output like ARN, ID and Tags name etc and destroy infrastructure in your AWS account. This testing is written in GO, so you need a GO environment in your system.

You need to run the following command in the testing folder:

  go test -run Test
