File naming conventions (.tf files) in Terraform - Mini Project: Build & Apply

File Naming Conventions for Terraform (.tf) Files

📖 Scenario: You are working on a Terraform project to manage cloud infrastructure. To keep your project organized and easy to understand, you need to follow proper file naming conventions for your Terraform files.Good file names help your team quickly find and update the right files without confusion.

🎯 Goal: Create Terraform files with clear and standard names that describe their purpose. This will help you and others maintain the infrastructure code easily.

📋 What You'll Learn

Create a Terraform file named main.tf for the primary configuration.

Create a Terraform file named variables.tf to declare input variables.

Create a Terraform file named outputs.tf to declare output values.

Create a Terraform file named providers.tf to configure providers.

💡 Why This Matters

🌍 Real World

Terraform projects often grow large. Using clear file names helps teams find and update code quickly.

💼 Career

Cloud engineers and DevOps professionals must organize infrastructure code well to collaborate and maintain systems efficiently.

1

Create the main Terraform configuration file

Create a Terraform file named main.tf that will hold the primary resource definitions.

Terraform

# Create a file named main.tf
# Your code here

Need a hint?

The main.tf file usually contains your main infrastructure resources.

2

Create the variables declaration file

Create a Terraform file named variables.tf to declare an input variable called region of type string.

Terraform

# This is the main.tf file
resource "null_resource" "example" {}

# Create a file named variables.tf
# Your code here

Need a hint?

The variables.tf file holds all input variable declarations.

3

Create the outputs declaration file

Create a Terraform file named outputs.tf to declare an output called resource_id that outputs the ID of the null_resource.example.

Terraform

# This is the main.tf file
resource "null_resource" "example" {}

variable "region" {
  type = string
}

# Create a file named outputs.tf
# Your code here

Need a hint?

The outputs.tf file holds all output declarations to expose values after deployment.

4

Create the providers configuration file

Create a Terraform file named providers.tf to configure the null provider with no extra settings.

Terraform

# This is the main.tf file
resource "null_resource" "example" {}

variable "region" {
  type = string
}

output "resource_id" {
  value = null_resource.example.id
}

# Create a file named providers.tf
# Your code here

Need a hint?

The providers.tf file configures the providers your Terraform code uses.
