Remote state data source for cross-project in Terraform - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a remote state data source using Terraform.

Terraform

data "terraform_remote_state" "example" {
  backend = "[1]"
  config = {
    bucket = "my-terraform-state"
    key    = "state.tfstate"
    region = "us-west-2"
  }
}

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

💡 Hint

Common Mistakes

Using 'local' instead of 's3' for remote state backend.

Confusing 'gcs' (Google Cloud Storage) with AWS S3.

The backend specifies the remote state storage type. For AWS S3, use s3.

2fill in blank

medium

Complete the code to reference the remote state output named 'vpc_id'.

Terraform

output "vpc_id" {
  value = data.terraform_remote_state.example.[1][0]
}

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

💡 Hint

Common Mistakes

Using dot notation directly on outputs which is invalid.

Trying to access output without referencing 'outputs' map.

Remote state outputs are accessed as a map using bracket notation, e.g., outputs["vpc_id"].

3fill in blank

hard

Fix the error in the remote state data source block to correctly specify the S3 bucket region.

Terraform

data "terraform_remote_state" "example" {
  backend = "s3"
  config = {
    bucket = "my-terraform-state"
    key    = "state.tfstate"
    region = "[1]"
  }
}

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

💡 Hint

Common Mistakes

Using a non-existent AWS region.

Typos in the region string.

The correct AWS region for the bucket is us-west-2. Using an invalid region like 'us-west-3' causes errors.

4fill in blank

hard

Fill both blanks to configure the remote state data source for a Google Cloud Storage bucket.

Terraform

data "terraform_remote_state" "example" {
  backend = "[1]"
  config = {
    bucket = "my-gcs-bucket"
    prefix = "[2]"
  }
}

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

💡 Hint

Common Mistakes

Using 's3' backend for GCS bucket.

Leaving prefix empty or incorrect.

For Google Cloud Storage, the backend is gcs. The prefix is the folder path inside the bucket, e.g., terraform/state.

5fill in blank

hard

Fill all three blanks to correctly reference a remote state output named 'subnet_ids' from an Azure backend.

Terraform

data "terraform_remote_state" "example" {
  backend = "[1]"
  config = {
    resource_group_name  = "myResourceGroup"
    storage_account_name = "mystorageaccount"
    container_name       = "tfstate"
    key                  = "prod.terraform.tfstate"
  }
}

output "subnet_ids" {
  value = data.terraform_remote_state.example.[2][[3]]
}

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

💡 Hint

Common Mistakes

Using wrong backend name like 's3' for Azure.

Accessing outputs without quotes around keys.

The backend for Azure is azurerm. Remote state outputs are accessed via the outputs map, and keys must be quoted strings like "subnet_ids".
