exercise 2

Terraform is an infrastructure-as-code (IaC) platform that allows users to manage and integrate various external resources as united infrastructure. This is achieved by using the proprietary HashiCorp Configuration Language (HCL) or JSON.

This course is a comprehensive introduction to Terraform. It helps users build confidence through foundational understanding of Terraform’s approach to resource management and the coding environment. You’ll start with an introduction to Terraform and learn how to set up local files. You’ll then take your learning to the cloud, managing remote resources by identifying unique resources and dependencies. Next, you’ll learn the modules and data structures unique to Terraform before practicing various techniques for infrastructure management, including triggers, resource creation, and backend code.

By the end of this course, you’ll have learned to think creatively and be ready to solve production and deployment problems through Terraform.

Beginner’s Guide to Terraform

## Variables
Variables in Terraform allow modules to take the input. Since modules are similar to procedures in programming languages, they take the input, return an output, and change the state of resources.



Variables provide the mechanism for inputs to be given and for the outputs to be returned to the consumer of the module. Variables are a critical aspect of Terraform modules.



## A simple module variable

We’ve created a directory named `ltthw_variable/variable_module` and then changed the directory to `ltthw_variables/variable_module`. Now we’ll create a `variable_module.tf` file and write the following content in it:
