Practice - 5 Tasks

Complete the code to initialize a Terraform workspace in a monorepo setup.

💡 Hint

Common Mistakes

Using 'apply' before initializing causes errors.

Confusing 'plan' with initialization.

The terraform init command initializes the working directory containing Terraform configuration files. This is the first step in any Terraform workflow, including monorepo setups.

Complete the code to apply Terraform changes only in a specific directory of a multi-repo setup.

Terraform

terraform -chdir=[1] apply

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

Cmain.tf

💡 Hint

Common Mistakes

Using a filename instead of a directory.

Confusing state files with directories.

The -chdir option tells Terraform to run commands in the specified directory. In a multi-repo setup, you apply changes in the directory containing the Terraform code, such as modules/network.

Fix the error in the Terraform backend configuration for a monorepo by completing the missing backend type.

Terraform

terraform {
  backend "[1]" {
    bucket = "my-terraform-state"
    region = "us-east-1"
  }
}

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

💡 Hint

Common Mistakes

Using 'local' backend when remote state is needed.

Confusing cloud providers for backend type.

The backend type s3 configures Terraform to store state files in an AWS S3 bucket, which is common in monorepo setups for centralized state management.

4fill in blank

hard

Fill both blanks to define a Terraform workspace command and its purpose in a multi-repo environment.

Terraform

terraform workspace [1] [2]

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

Anew

Blist

Cdev

Ddelete

💡 Hint

Common Mistakes

Using 'list' instead of 'new' to create a workspace.

Using an invalid workspace name.

The command terraform workspace new dev creates a new workspace named 'dev'. Workspaces help manage multiple environments in a multi-repo setup.

5fill in blank

hard

Fill all three blanks to complete a Terraform command that plans changes for a specific workspace in a monorepo.

Terraform

terraform workspace [1] && terraform plan -var-file=[2]/[3].tfvars

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

Aselect

Benvs

Cprod

Dcreate

Attempts:

💡 Hint

Common Mistakes

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

Incorrect directory or filename for variable files.

The command selects the 'prod' workspace and runs a plan using the variable file located in the 'envs' directory. This is typical in monorepo setups to isolate environment configurations.
