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.

Using Terraform to provision Cloud Run services

In our example, we will deploy two Cloud Run services. The first one is a simple Hello example. The second service accesses the Redis database. We will include the code for both services for your reference so that you can build your own container images. The sample code uses container images from a public container repository.

We want the Cloud Run service to be publicly accessible – that is, not require any authentication. For enhanced security, we will allow the Cloud Run services to ingress only via the load balancer and use the service account we provisioned in the foundation layer.

First, let’s have a look at how we deploy the hello service. First, we must provision the Cloud Run service using the google_cloud_run_service resource. We need to specify the container source and the service account name. To restrict the ingress restriction, we need to add an annotation, as follows:
