If you want to save time and avoid pitfalls when working with Terraform and the HashiCorp Configuration Language (HCL), this easy-to-use cookbook gives you battle-tested, step-by-step recipes to help you deploy with confidence across all of your infrastructure stacks. Each recipe includes self-contained code solutions that you can freely use, along with a discussion of how and why they work.

Terraform comes standard with an extensive library of built-in functions. Available in any Terraform file (including modules) and the Terraform Console, functions can validate, combine format, and transform data. Functions are integral to creating reusable and less error-prone infrastructure by allowing for a more complex definition of your infrastructure as code.

We use Terraform Output Values to illustrate the result of applying a function to an input variable. For traditional Terraform uses, this is not needed as Terraform can process the function without outputting its value to the user. Running terraform console allows you to experiment with any built-in functions mentioned in these examples.
