Pattern: Unencrypted Google Compute disk

Issue: -

Description

By default, Compute Engine encrypts all data at rest. Compute Engine handles and manages this encryption for you without any additional actions on your part.

If the disk_encryption_key block is included in the resource declaration then it must include a raw_key or kms_key_self_link.

To use the default offering of Google managed keys, do not include a disk_encryption_key block at all.

Resolution: Enable encryption for compute disks.

Examples

Example of incorrect code:

resource "google_compute_disk" "bad_example" {
	# ... 
	disk_encryption_key {}
	# ...
}

Example of correct code:

resource "google_compute_disk" "good_example" {
	disk_encryption_key {
		kms_key_self_link = "something"
	}
}

resource "google_compute_disk" "good_example" {
	disk_encryption_key {
		raw_key = "something"
	}
}
