Terraform Built-in Functions
Explore a wide range of Terraform's built-in functions for string manipulation, list processing, type conversions, and more to enhance your configurations.
Unlock Dynamic Configs
Terraform's built-in functions are like mini-programs that help you process and transform values directly within your configuration files.
They allow you to create dynamic, reusable, and more intelligent infrastructure definitions.
- Transform data: Change strings, numbers, or lists.
- Compute values: Perform calculations or logical checks.
- Generate dynamic content: Create resource names or tags on the fly.
Text Transformations
String functions are essential for manipulating text. Two basic ones are upper() and lower(), which change the case of a string.
They're useful for standardizing naming conventions or matching specific requirements.
variable "region_code" {
type = string
default = "us-east-1"
}
output "upper_region" {
value = upper(var.region_code)
}
output "lower_example" {
value = lower("AWS_REGION")
