Terraform Basics - Functions

The Terraform core binary comes with a set of built-in functions that can be used to manipulate data within you configuration. The syntax for using a function is pretty straightforward, you start with the function name, followed by a set of parentheses.

Functions are used to transform data in your configuration or sometimes reference objects outside the configuration, in cases like file() or timestamp(). You can use the terraform console to evaluate function expressions before putting them in your code.

Although you cannot define custom functions directly in Terraform, you can create modules that perform the data transformation you want or leverage the new provider-defined functions available in Terraform 1.8.

This is part of the Terraform Basics series, a set of video created to focus on one aspect of Terraform and explain it in detail. While not a replacement for a full course, if there's something in Terraform that doesn't quite click with you, hopefully Terraform Basics will fill in the gaps.
