Description

GKE cluster nodes should be launched with Shielded VM enabled by setting the enable_shielded_nodes attribute to true in the google_container_cluster resource. Failing to enable Shielded VM features exposes cluster nodes to potential rootkit and boot-level malware attacks, as these features help ensure node integrity through secure boot and trusted platform module (TPM) protections. For secure configuration, use:

resource "google_container_cluster" "secure" {
  name                  = "my-gke-cluster"
  location              = "us-central1"
  enable_shielded_nodes = true
}

Compliant Code Examples

resource "google_container_cluster" "negative1" {
  name                  = "my-gke-cluster"
  location              = "us-central1"
  enable_shielded_nodes = true
}

Non-Compliant Code Examples

resource "google_container_cluster" "false" {
  name                  = "my-gke-cluster"
  location              = "us-central1"
  enable_shielded_nodes = false
}
