Terraform Workspace - Day 5

In Terraform, workspaces provide a way to manage multiple instances of the same infrastructure within a single configuration. Workspaces allow you to create different environments, such as development, staging, and production, without duplicating the entire configuration. Each workspace has its own set of Terraform state files, allowing you to manage different environments independently.

Command -> terraform workspace

Attributes for the above command are,

• new - To create a new workspace

• list - To list available workspaces ('*' denotes the current workspace which you are in)

• show - To show the name of the current workspace

• select - To select a workspace

• delete - To delete a workspace

State isolation

• Each workspace has its own state file (.tfstate) that contains the information about the deployed infrastructure.

• '.tfstate' file will be present under the folder, 'terraform.tfstate.d' in separate workspace environment. For default workspace '.tfstate' file will be under root folder.

• This state isolation allows you to have independent Terraform state for each workspace, avoiding conflicts between environments.

Terraform commands with workspace

You need to switch workspaces using terraform workspace select <workspace_name> before running terraform commands for a specific environment.

⏹ Create a new workspace for development

terraform workspace new dev

⏹ Switch to the development workspace

terraform workspace select dev

⏹ Apply the configuration for the development workspace

terraform apply

⏹ Switch to the production workspace

terraform workspace select prod

⏹ Apply the configuration for the production workspace

terraform apply

So basically, workspaces in Terraform provide a powerful way to manage and deploy infrastructure configurations across different environments with ease and efficiency.
