Workspaces and remote state in Terraform - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a Terraform workspace?

A Terraform workspace is like a separate workspace folder where Terraform keeps its state files. It lets you manage multiple environments (like dev, test, prod) using the same configuration but with isolated states.

Why use remote state in Terraform?

Remote state stores Terraform's state file in a shared place like cloud storage. This helps teams work together safely, avoids state conflicts, and keeps the state backed up and secure.

How does Terraform prevent state conflicts when using remote state?

Terraform uses locking mechanisms on remote state backends to prevent multiple people from changing the state at the same time, avoiding conflicts and corruption.

beginner

What is the difference between local and remote state?

Local state is saved on your computer, which is simple but risky for teams. Remote state is saved in a shared service like AWS S3 or Terraform Cloud, making it safer and better for collaboration.

How do Terraform workspaces help manage multiple environments?

Workspaces let you switch between different state files easily without changing your code. For example, you can have a 'dev' workspace and a 'prod' workspace, each with its own infrastructure state.

What does a Terraform workspace primarily isolate?

A Terraform configuration files

B Provider plugins

C State files

D Terraform CLI versions

Terraform workspaces isolate state files, allowing multiple states for the same configuration.

Which of these is a benefit of using remote state?

A Allows multiple users to share state safely

B Automatically writes Terraform code

C Runs Terraform faster locally

D Removes the need for state files

Remote state allows teams to share and lock state files safely.

What happens if two users try to update the remote state at the same time?

A Terraform ignores one user's changes

B Terraform merges the changes automatically

C Terraform deletes the state file

D Terraform locks the state to prevent conflicts

Terraform uses locking to prevent simultaneous state updates.

Where is local Terraform state stored by default?

A In a database

B On the user's local machine

C In Terraform Cloud

D In a cloud storage bucket

Local state is stored on the user's local machine by default.

How do you switch between Terraform workspaces?

A Using the command 'terraform workspace select <name>'

B By editing the Terraform configuration file

C By changing the provider version

D By deleting the state file

You switch workspaces with 'terraform workspace select '.
