Terraform: From Beginner to Master with Examples in AWS

Type Constraints - Map

Explore how to declare maps with type constraints in Terraform variables, initialize them with specific keys and values, and retrieve individual map entries using keys. Understand how type enforcement works when assigning values and practice running Terraform commands to apply and destroy these configurations.

We'll cover the following...

Map

A map is a set of values indexed by key name. You can give a map a type, which will be the type of the values.

Project example

Consider the following code:

C++
variable "my_map" {
    type = map(number)
    default = {
        "alpha" = 2
        "bravo" = 3
    }
}
output "map" {
    value = var.my_map
}
output "alpha_value" {
    value = var.my_map["alpha"]
}

In this project, we are creating a map of type number. ...
