This repo contains an example of GCP - AWS - Consul cluster deployment.

AWS VPC

This module will create VPC in AWS region "us-east-1"

AWS Client VPN

This module will create AWS Client VPN

AWS EC2 (Consul servers)

This module will create a needed number of Consul server in AWS

AWS IPsec VPN

This module will create a VPN connection between AWS and GCP.

GCP VPC

This module will create VPC in GCP region "us-east4"

GCP Site to Site

This module will create GCP Site to Site VPN

GCP compute (Consul servers)

This module will create a needed number of Consul server in GCP

Prerequisites

• Terraform "~> 0.13.0"
• AWS Account
• Basic Consul knowledge
• GCP Account

Prepare you own AWS AMIs with Packer

• AWS PACKER-CONSUL-SERVER

Prepare you own GCP Image with Packer

• GCP PACKER-CONSUL-SERVER

Clone the repo

git clone https://github.com/chavo1/gcp-aws-vpn-consul-terraform.git
cd gcp-aws-vpn-consul-terraform
terraform init
terraform apply

• After the deployment Terraform will generate a file into the root directory "config-cvpn.ovpn". So you can use it to connect to the environment in both DCs with AWS Client VPN.
• VPN client depend on your choice, in my case I use tunnelblick.

To test you will need Kitchen and Selenium:

• Kitchen provides a test harness to execute infrastructure code on one or more platforms in isolation.
• Install kitchen.ci
• Install selenium and all its dependencies on Mac with brew

$ brew install selenium-server-standalone
$ brew cask install java

# GeckoDriver for firefox
$ brew install geckodriver 

# Chromedriver for chrome
$ brew cask install chromedriver 

Than simply execute a following commands:

bundle exec kitchen converge
bundle exec kitchen verify
bundle exec kitchen destroy
