💡 Hint

Common Mistakes

Using 'select' which only switches to existing workspace.

Using 'show' which displays current workspace.

Using 'list' which only lists workspaces.

The command terraform workspace create staging creates a new workspace named 'staging'.

💡 Hint

Common Mistakes

Using 'list' which shows all workspaces, not current.

Using 'select' which switches workspace.

Using 'create' which makes a new workspace.

The command terraform workspace show displays the current workspace.

4fill in blank

hard

Fill both blanks to list all workspaces and then switch to the 'dev' workspace.

💡 Hint

Common Mistakes

Using 'create' instead of 'select' to switch workspace.

Using 'show' instead of 'list' to see all workspaces.

First, terraform workspace list shows all workspaces. Then, terraform workspace select dev switches to the 'dev' workspace.

5fill in blank

hard

Fill all three blanks to create a workspace 'test', switch to it, and then show the current workspace.

Terraform

terraform workspace [1] test
terraform workspace [2] test
terraform workspace [3]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing up 'list' with 'show'.

Using 'select' before 'create'.

Skipping the 'show' command.

Use create to make 'test' workspace, select to switch to it, and show to confirm the current workspace.

Practice

1. What is the main purpose of using terraform workspaces?

easy

A. To store Terraform modules

B. To write Terraform code faster

C. To manage multiple environments like development and production with one configuration

D. To increase the speed of Terraform apply

Solution

1. Step 1: Understand workspace purpose

   Workspaces allow you to keep separate states for different environments using the same Terraform code.

2. Step 2: Compare options

   Options A, B, and C do not relate to managing environments or state separation.

3. Final Answer:

   To manage multiple environments like development and production with one configuration -> Option C

4. Quick Check:

   Workspaces = separate environment states [OK]

Hint: Workspaces separate states for different environments [OK]

Common Mistakes:

• Thinking workspaces speed up Terraform runs
• Confusing workspaces with modules
• Believing workspaces store code

2. Which command correctly switches to a workspace named testing?

easy

A. terraform workspace select testing

B. terraform switch workspace testing

C. terraform workspace switch testing

D. terraform use workspace testing

Solution

1. Step 1: Recall correct workspace switch syntax

   The correct command to switch workspaces is terraform workspace select [name].

2. Step 2: Validate options

   Options A, B, and D use incorrect command syntax not recognized by Terraform.

3. Final Answer:

   terraform workspace select testing -> Option A

4. Quick Check:

   Switch workspace = terraform workspace select [name] [OK]

Hint: Use 'terraform workspace select <name>' to switch [OK]

Common Mistakes:

• Using 'switch' instead of 'select'
• Mixing command order
• Adding extra words like 'workspace' twice

3. Given the commands below, what will be the output of terraform workspace show after these steps?

terraform workspace new dev
terraform workspace select dev
terraform workspace new prod
terraform workspace select prod
terraform workspace show

medium

A. prod

B. dev

C. default

D. Error: workspace not found

Solution

1. Step 1: Follow workspace creation and switching

   First, 'dev' workspace is created and switched to. Then 'prod' workspace is created and switched to.

2. Step 2: Check current workspace

   After switching to 'prod', running 'terraform workspace show' outputs the current workspace name, which is 'prod'.

3. Final Answer:

   prod -> Option A

4. Quick Check:

   Last switched workspace = prod [OK]

Hint: Last 'terraform workspace select' sets current workspace [OK]

Common Mistakes:

• Assuming default workspace remains active
• Confusing creation with switching
• Expecting error without reason

4. You run terraform workspace select staging but get an error saying the workspace does not exist. What should you do to fix this?

medium

A. Rename the workspace to default

B. Run terraform init again

C. Delete the current workspace and try again

D. Run terraform workspace new staging to create it first

Solution

1. Step 1: Understand error cause

   The error means the workspace 'staging' does not exist yet in Terraform state.

2. Step 2: Create the missing workspace

   Use terraform workspace new staging to create it before switching.

3. Final Answer:

   Run terraform workspace new staging to create it first -> Option D

4. Quick Check:

   Workspace must exist before select [OK]

Hint: Create workspace before using it [OK]

Common Mistakes:

• Trying to switch without creating workspace
• Reinitializing Terraform unnecessarily
• Deleting workspaces without cause

5. You want to manage three environments: dev, test, and prod using one Terraform configuration. Which approach best uses workspaces to achieve this safely?

hard

A. Use one workspace and manually change resource names for each environment

B. Create separate workspaces named dev, test, prod and switch before applying changes

C. Create three separate Terraform configurations for each environment

D. Use workspaces only for prod and dev, but not test

Solution

1. Step 1: Identify workspace use for multiple environments

   Workspaces allow managing multiple environment states with one config by switching between them.

2. Step 2: Evaluate options for safety and simplicity

   Create separate workspaces named dev, test, prod and switch before applying changes uses separate workspaces for each environment, which is safe and clean. Use one workspace and manually change resource names for each environment risks conflicts. Create three separate Terraform configurations for each environment duplicates code. Use workspaces only for prod and dev, but not test is inconsistent.

3. Final Answer:

   Create separate workspaces named dev, test, prod and switch before applying changes -> Option B

4. Quick Check:

   Separate workspaces = safe multi-env management [OK]

Hint: Use one workspace per environment for safety [OK]

Common Mistakes:

• Mixing environments in one workspace
• Duplicating configs unnecessarily
• Ignoring test environment
