Terraform.tfvars file - Mini Project: Build & Apply

Using a Terraform.tfvars File for Variable Configuration

📖 Scenario: You are setting up a Terraform project to create cloud infrastructure. You want to keep your variable values separate from your main configuration files for easier management and security.

🎯 Goal: Create a terraform.tfvars file to define variable values for your Terraform project. This file will hold exact values for variables like region, instance_type, and instance_count.

📋 What You'll Learn

Create a terraform.tfvars file with exact variable assignments

Include variables: region, instance_type, and instance_count

Use exact values: region = "us-west-2", instance_type = "t2.micro", instance_count = 3

Ensure the file syntax is valid for Terraform variable files

💡 Why This Matters

🌍 Real World

Terraform.tfvars files are used in real projects to separate variable values from code, making infrastructure easier to manage and update.

💼 Career

Knowing how to use terraform.tfvars files is essential for cloud engineers and DevOps professionals managing infrastructure as code.

1

Create the terraform.tfvars file with the region variable

Create a terraform.tfvars file and add the variable region with the exact value "us-west-2".

Terraform

# Your code here

Need a hint?

Use the format variable_name = "value" in the terraform.tfvars file.

2

Add the instance_type variable to terraform.tfvars

In the terraform.tfvars file, add the variable instance_type with the exact value "t2.micro" below the region variable.

Terraform

region = "us-west-2"
# Your code here

Need a hint?

Add a new line with instance_type = "t2.micro" below the existing region variable.

3

Add the instance_count variable to terraform.tfvars

In the terraform.tfvars file, add the variable instance_count with the exact value 3 below the instance_type variable.

Terraform

region = "us-west-2"
instance_type = "t2.micro"
# Your code here

Need a hint?

Add a new line with instance_count = 3 below the existing variables.

4

Complete the terraform.tfvars file with all variables

Ensure the terraform.tfvars file contains the variables region, instance_type, and instance_count with the exact values "us-west-2", "t2.micro", and 3 respectively.

Terraform

region = "us-west-2"
instance_type = "t2.micro"
instance_count = 3
# Verify all variables are present

Need a hint?

Check that all three variables are present with the exact values.
