Learn how to build projects using Terraform.

DevOps for Developers

In this module, you will work from the ground up, starting with what Terraform is and the problems it solves. It will then guide you through the features of Terraform. You will build on your knowledge with the end goal of you being comfortable building projects using Terraform.

Terraform: From Beginner to Master with Examples in AWS

## 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:



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`. We are initialising the map to have two keys: alpha and bravo. The values for the keys are `2` and `3` respectively. The fact that we have specified
that the map is of type `(number)` means that all of the values have to match the number constraint.
