Introduction

Terraform allows you to define variables with different data types. Understanding these data types is essential for creating flexible and maintainable infrastructure as code. In this repository, we will explore various data types and provide examples for each.

String

A string is a sequence of characters enclosed in double or single quotes. It is commonly used for representing text values.

Example:

variable "my_string" {
  type    = string
  default = "Hello, Terraform!"
}

Number

A number represents numeric values, including integers and floating-point numbers.

Example:

variable "my_number" {
  type    = number
  default = 42
}

List

A list is an ordered collection of values. It can contain elements of different data types.

Example:

variable "my_list" {
  type    = list(any)
  default = ["apple", 42, true]
}

Map

A map is a collection of key-value pairs. It is useful for representing structured data.

Example:

variable "my_map" {
  type    = map(any)
  default = {
    name    = "John"
    age     = 30
    country = "USA"
  }
}

Bool

A boolean represents true or false values.

Example:

variable "is_enabled" {
  type    = bool
  default = true
}
