Bulk import strategies in Terraform - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main purpose of bulk import strategies in Terraform?

Bulk import strategies help bring many existing cloud resources under Terraform management efficiently, saving time and reducing manual work.

How does the 'terraform import' command work in bulk import scenarios?

The 'terraform import' command links an existing resource to a Terraform resource block, but it works one resource at a time, so scripts or loops are used to import many resources.

beginner

Why is scripting important in bulk import strategies?

Scripting automates repetitive import commands, making it faster and less error-prone to import many resources at once.

What is a common challenge when performing bulk imports in Terraform?

Ensuring the Terraform configuration matches the existing resources exactly to avoid drift or errors after import.

beginner

Name one best practice for bulk importing resources into Terraform.

Test imports on a small set of resources first, verify the state, then scale up to bulk import to avoid mistakes.

What does the 'terraform import' command do?

A Deletes resources from Terraform state

B Creates new resources in the cloud

C Updates Terraform configuration files automatically

D Links existing resources to Terraform state

'terraform import' connects existing cloud resources to Terraform's state without creating or deleting them.

Which method helps automate bulk imports in Terraform?

A Writing scripts to run multiple import commands

B Manually running import for each resource

C Using 'terraform apply' directly

D Deleting resources before import

Scripts automate running many 'terraform import' commands, making bulk import efficient.

Why should you verify Terraform configuration before bulk import?

A To speed up the import process

B To ensure resource definitions match existing resources

C To delete unused resources automatically

D To create new resources instead

Matching configuration prevents errors and drift after import.

What is a risk of bulk importing without testing first?

A Importing wrong resources or corrupting state

B Terraform will create duplicate resources

C Cloud provider will charge extra fees

D Terraform will ignore imported resources

Testing helps avoid mistakes that can corrupt Terraform state or import wrong resources.

Which of these is NOT a bulk import strategy?

A Using scripts to automate imports

B Manual import one by one

C Using Terraform Cloud to import automatically

D Writing configuration to match existing resources

Terraform Cloud does not provide automatic bulk import; automation is done via scripts and configuration.

Explain how you would perform a bulk import of cloud resources into Terraform.

Think about commands, automation, configuration, and testing.

What are the key challenges and best practices when doing bulk imports in Terraform?

Consider risks and how to prevent them.
