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.

Provisioning Redis and connecting it via a VPC connector

Note

The code for this section can be found in the chap07/foundation directory in this book’s GitHub repository.

Similar to what we did in the previous chapter, we will start by building the foundation. This architecture requires several project services, a service account, and a VPC with one subnet. As we used the same setup in the previous chapter, we can simply reuse the code from the previous chapter by copying the following files:

  • project-services.tf
  • sa.tf
  • vpc.tf

We only need to change our variable assignments in terraform.tfvars.

Note

Of course, it would be even more efficient to create modules and then use them.

Provisioning a basic Redis instance in Google Cloud using Terraform only requires a few lines of code. However, for a Cloud Run service to connect to Redis, we need to create a VPC connector (https://cloud.google.com/vpc/docs/configure-serverless-vpc-access).
