Show resources to be destroyed

↓

User confirms destruction

Yes↓

Destroy resources in cloud

↓

Update state file to remove destroyed resources

↓

End

Terraform destroy loads the current state, plans resource removal, asks for confirmation, then deletes resources and updates the state.

Execution Sample

Terraform

terraform destroy
# Confirm with 'yes' when prompted
# Resources get deleted
# State file updates

This command deletes all resources tracked by Terraform and cleans up the state.

Process Table

Step	Action	Evaluation	Result
1	Run 'terraform destroy'	Command starts	Terraform loads state file
2	Plan destruction	Identify all resources	List resources to delete
3	Prompt user	Wait for confirmation	User inputs 'yes'
4	Destroy resources	Send delete requests	Resources deleted in cloud
5	Update state	Remove destroyed resources	State file updated
6	Finish	All resources removed	Cleanup complete

💡 All resources destroyed and state file cleaned up, process ends.

Status Tracker

Variable	Start	After Step 2	After Step 4	Final
state_file	Contains all resources	Marked for deletion	Empty or updated	Cleaned state

Key Moments - 3 Insights

Why does Terraform ask for confirmation before destroying?

Terraform shows planned deletions (see step 3 in execution_table) to prevent accidental loss of resources.

What happens if you say 'no' at the confirmation prompt?

Terraform stops the destroy process at step 3, so no resources are deleted and state remains unchanged.

Does Terraform delete resources immediately after running the command?

No, it first plans and waits for confirmation (steps 2 and 3), then deletes resources (step 4).

Visual Quiz - 3 Questions

Look at the execution_table, what happens at step 4?

A Terraform updates the state file

B Terraform sends delete requests to cloud resources

C Terraform waits for user confirmation

D Terraform loads the state file

💡 Hint

Check the 'Action' and 'Result' columns at step 4 in execution_table.

At which step does Terraform ask for user confirmation?

A Step 5

B Step 2

C Step 3

D Step 1

💡 Hint

Look for 'Prompt user' action in execution_table.

If the user inputs 'no' at confirmation, what changes in variable_tracker?

A state_file remains unchanged

B state_file is updated to remove resources

C state_file is deleted

D state_file is corrupted

💡 Hint

Refer to key_moments about confirmation and step 3 in execution_table.

Full Transcript

Terraform destroy is a command to remove all resources managed by Terraform. When you run it, Terraform first loads the current state file to know what resources exist. Then it plans which resources will be deleted and shows this list to you. It asks for your confirmation before proceeding. If you type 'yes', Terraform sends delete requests to the cloud provider to remove the resources. After deletion, it updates the state file to reflect that these resources no longer exist. If you say 'no', Terraform stops and does not delete anything. This process helps you clean up your infrastructure safely and avoid accidental deletions.
