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.

Terraform types and values

Note

The code for this section is under chap03/types in the GitHub repo of this book.

Before we go into expressions, let’s have a closer look at Terraform types and values. We have used Terraform types in the variable declarations. Terraform has the following types:

  • String
  • Number
  • Bool(ean)
  • List
  • Map

The first three are self-explanatory. Lists are sequences of values denoted by square brackets ([ and ]) and separated by commas. Maps are groups of named values—that is, name = value. A map is surrounded by curly brackets ({ and }) and separated by commas. Lists and maps can also be nested. The following are some common types as defined in a variable definition file:

chap03/type/terraform.tfvars

string = "This is a string"
number = 14
bool   = true
list   = ["us-west1", "us-west2"]
map    = { us-west1 = "Oregon", us...
