Types

  • string: a sequence of Unicode characters representing some text, like "hello".
  • number: a numeric value. The number type can represent both whole numbers like 15 and fractional values like 6.283185.
  • bool: a boolean value, either true or false. bool values can be used in conditional logic.
  • list or tuple: a sequence of values, like ["us-west-1a", "us-west-1c"]. Elements in a list or tuple are identified by consecutive whole numbers, starting with zero.
  • map or object: a group of values identified by named labels, like {name = "Mabel", age = 52}.

Examples

 type        = list(string)
 default     = []
List example:  ["us-west-1a", "us-west-1c"]
 type        = string
 default     = null

Map/Object example

{
  name = "John"
  age  = 52
}
variable "amis" {
 type = "map"
 default = {
   "us-east-1" = "ami-b374d5a5"
   "us-west-2" = "ami-4b32be2b"
 }
}


Object list

variable "Your_Var_Name" {
  type = list
  default = [{
    "your_var_1" = "your_value_1"
    "your_var_2" = "your_value_1"
    "your_var_3" = "your_value_1"
  }]
}
