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

## List
A `list` is a type of a list. You can have a list of strings like `["foo", "bar"]` or a list of numbers `[2,
4, 7]`. The type means that every element in the `list` will be of that type.

## Project example
Consider the following example:



variable "a" {
    type = list(string)
    default = ["foo", "bar", "baz"]
}

output "a" {
    value = var.a
}

output "b" {
    value = element(var.a, 1)
}

output "c" {
    value = length(var.a)
}


In the above code, we define a `list` in variable `"a"` to be a list of strings.
To do this, we use the word `list` and put the type we want in brackets. Then, to set the value for a list, we put the elements between square brackets.
