Terraform 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}.

Example:

 type        = list(string)
 default     = []

List example: ["us-west-1a", "us-west-1c"]
