In this **Terraform Tutorial**, we’ll explore **Terraform Variables** and learn how to use them effectively to make your Terraform configurations more flexible, reusable, and powerful. If you’re a beginner working with Terraform, mastering variables is a crucial step toward writing clean and scalable Infrastructure as Code (IaC).
Terraform variables allow you to customize and parameterize your infrastructure definitions, so you don’t have to hardcode values in your configuration files. This makes it easier to manage environments, share code across teams, and maintain your infrastructure at scale.
In this video, we’ll cover:
* What Terraform Variables are and why they’re important
* The different types of variables in Terraform (string, number, bool, list, map, etc.)
* Declaring and defining variables in Terraform configuration files
* Setting variable values using `terraform.tfvars` and command-line options
* Default values, validation, and descriptions for better usability
* Environment variables and sensitive variables for security
* Real-world examples of using variables in AWS resource creation
* Best practices for managing variables in Terraform projects
By the end of this tutorial, you’ll have a solid understanding of how to declare, configure, and use variables in Terraform to simplify and optimize your workflows. You’ll see how variables make your infrastructure more dynamic, portable, and easier to maintain across different environments like development, staging,
