If you perform resource changes such as adding or deleting disks or Compute Engine instances without using Terraform, differences might occur between Terraform templates and created resources.

If you execute Terraform when such differences exist, operations might be unsuccessful.

In such a case, take appropriate action according to the following flowchart.
