Terraform Workspaces provide a way to manage multiple environments (e.g., development, staging, production) within a single Terraform configuration. Each workspace has its own state data, allowing you to isolate changes and manage different environments more effectively.

• Workspace: A named instance of a Terraform configuration with its own state data.
• Default Workspace: The initial workspace created when you start using Terraform. Named "default".
• Custom Workspaces: Additional workspaces you can create to manage different environments.

• Isolation: Each workspace has its own state, preventing changes in one environment from affecting another.
• Simplicity: Manage multiple environments without duplicating configuration files.
• Flexibility: Easily switch between environments using simple commands.

1. Objective: Create and manage multiple workspaces for different environments.
2. Steps:
   • Initialize a new Terraform configuration.
   • Create workspaces for dev, staging, and production.
   • Switch between these workspaces and observe the changes.

Step-by-Step Solution

1. Initialize Terraform:

   $ terraform init
   

2. Create Workspaces:

   $ terraform workspace new dev
   $ terraform workspace new staging
   $ terraform workspace new production
   

3. List Workspaces:

   $ terraform workspace list
   * default
     dev
     staging
     production
   

4. Switch to dev Workspace:

   $ terraform workspace select dev
   

5. Show Current Workspace:

   $ terraform workspace show
   dev
   

6. Switch to staging Workspace:

   $ terraform workspace select staging
   

7. Show Current Workspace:

   $ terraform workspace show
   staging
   

• Forgetting to Switch Workspaces: Always ensure you are in the correct workspace before applying changes.
• Workspace Naming: Use clear and consistent names for workspaces to avoid confusion.
• State Management: Remember that each workspace has its own state file. Changes in one workspace do not affect others.

Terraform Workspaces are a powerful feature for managing multiple environments within a single configuration. By isolating state data, workspaces help prevent unintended changes and simplify environment management. Practice creating, switching, and managing workspaces to become proficient in using this feature effectively.
