💡 Hint

Common Mistakes

Using 'apply' before initializing causes errors.

Confusing 'plan' with initialization.

Terraform uses init to initialize the working directory and set up the state backend.

💡 Hint

Common Mistakes

Using 'state list' only lists resource addresses, not full state details.

Using 'apply' changes infrastructure instead of showing state.

The terraform show command displays the current state or plan in a human-readable format.

💡 Hint

Common Mistakes

Using 'apply' changes infrastructure instead of just refreshing state.

Using 'plan' only shows changes but does not update state.

The terraform refresh command updates the state file to match the real infrastructure.

4fill in blank

hard

Fill both blanks to list all resources in the Terraform state and filter by resource type.

💡 Hint

Common Mistakes

Using 'show' instead of 'list' does not list resource addresses.

Using 'plan' is unrelated to state listing.

terraform state list lists all resources in state. Using grep aws_instance filters to show only AWS instances.

5fill in blank

hard

Fill the blanks to remove a resource from Terraform state safely.

💡 Hint

Common Mistakes

Using 'show' instead of 'rm' does not remove resources.

Confusing state 'rm' with 'destroy', which affects real infrastructure.

terraform state rm aws_instance.example removes the resource from state without affecting real infrastructure.
