Terraform file organization - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of splitting Terraform configuration into multiple files?

Splitting Terraform configuration into multiple files helps organize code by function or resource type, making it easier to read, maintain, and collaborate on.

beginner

What file typically contains the main Terraform resource definitions?

The main.tf file usually contains the primary resource definitions and core infrastructure code.

beginner

What is the role of variables.tf in Terraform projects?

variables.tf defines input variables that allow users to customize the configuration without changing the code directly.

intermediate

Why should Terraform state files be kept separate from configuration files?

Terraform state files track the real-world infrastructure state and should be kept separate and secure to avoid accidental changes and to enable collaboration.

beginner

How does using outputs.tf help in Terraform projects?

outputs.tf defines outputs that show important information after deployment, like IP addresses or resource IDs, making it easy to access key data.

Which file is best suited for defining Terraform input variables?

A variables.tf

B main.tf

C outputs.tf

D terraform.tfstate

variables.tf is used to declare input variables for customization.

Where should you put resource definitions in a Terraform project?

A main.tf

B variables.tf

C terraform.tfstate

D outputs.tf

Resource definitions belong in main.tf.

What is the main reason to keep Terraform state files separate and secure?

A To improve code readability

B To store input variables

C To track real infrastructure state and avoid accidental changes

D To define output values

State files track infrastructure and must be protected to prevent errors.

Which file would you check to find the IP address of a deployed server?

A variables.tf

B main.tf

C terraform.tfstate

D outputs.tf

outputs.tf defines values like IP addresses to display after deployment.

Why is it a good practice to organize Terraform files by purpose?

A To make the configuration harder to understand

B To improve readability and ease collaboration

C To reduce the number of files

D To avoid using variables

Organizing files by purpose helps teams read and maintain code easily.

Explain how you would organize files in a Terraform project and why.

Think about separating code by function and protecting state.

Describe the role of Terraform state files and best practices for managing them.

State files are like a map of your deployed resources.
