💼 Career

Knowing terraform fmt is essential for cloud infrastructure roles to maintain readable and standardized Terraform code.

1

Create an unformatted Terraform configuration file

Create a file named main.tf with this exact unformatted content: variable "region"{default="us-west-2"}resource "aws_s3_bucket" "bucket"{bucket="mybucket"}

Terraform

# Create a file named main.tf with unformatted Terraform code
# Your code here

Need a hint?

Write the variable and resource blocks without spaces or new lines as shown.

2

Add a variable block with default value

Add a variable block named environment with a default value of dev to the existing main.tf file.

Terraform

variable "region"{default="us-west-2"}resource "aws_s3_bucket" "bucket"{bucket="mybucket"}
# Add variable "environment" with default "dev" below
# Your code here

Need a hint?

Write the variable block exactly as variable "environment" {default = "dev"}.

3

Add a minimally formatted resource block

Add a resource block named aws_instance with the name web and an attribute ami set to ami-123456 in main.tf. Write it without extra spaces or new lines.

Terraform

variable "region"{default="us-west-2"}resource "aws_s3_bucket" "bucket"{bucket="mybucket"}variable "environment" {default = "dev"}
# Add resource "aws_instance" "web" with ami="ami-123456" below
# Your code here

Need a hint?

Write the resource block exactly as resource "aws_instance" "web"{ami="ami-123456"}.

4

Format the Terraform configuration using terraform fmt

Run the command terraform fmt in the directory containing main.tf to format the Terraform configuration file properly.

Terraform

# Run terraform fmt command in your terminal
# Your code here
