Terraform for Google Cloud Essential Guide

Overview of this book

Google Cloud has adopted Terraform as the standard Infrastructure as Code tool. This necessitates a solid understanding of Terraform for any cloud architect or engineer working on Google Cloud. Yet no specific resources are available that focus on how to use Terraform on Google Cloud. This is the first book that teaches Terraform specifically for Google Cloud. You will take a journey from the basic concepts through to deploying complex architectures using Terraform. Using extensive code examples, you will receive guidance on how to authenticate Terraform in Google Cloud. As you advance, you’ll get to grips with all the essential concepts of the Terraform language as applied to Google Cloud and deploy complete working architectures at the push of a button. Finally, you’ll also be able to improve your Terraform workflow using Google Cloud native and third-party tools. By the end of this Terraform book, you will have gained a thorough understanding of Terraform and how to use it on Google Cloud, and be able to develop effective Terraform code, build reusable code, and utilize public domain Terraform modules to deploy on Google Cloud faster and more securely.

Overview

As we mentioned in Chapter 5, Managing Environments, one of the fundamental principles in modern application development is maintaining dev/prod parity (https://12factor.net/dev-prod-parity). That is, different environments, such as development, testing, and production environments, should be as similar as possible. Terraform is the ideal tool to set up any number of environments and then delete them once they’ve been used. To minimize the cost, it is a common practice to provision smaller instance sizes or zonal resources instead of larger and regional resources in development environments. As we have discussed previously, by combining modules and workspaces, we can use Terraform to provision equivalent environments quickly and with minimal repeated effort.

In this exercise, we want to deploy two GKE clusters, one for development and one for production. The two clusters should be nearly identical, except that we want to save costs for the development cluster. Thus...
