GCP Terraform Misconfiguration: Insufficient GKE Cluster Monitoring

Abstract

Terraform スクリプトは、Google Kubernetes Engine クラスターの監視サービスを無効にします。

Explanation

デフォルトでは、Google Kubernetes Engine (GKE) クラスターが、ポッドから Stackdriver Kubernetes Engine Monitoring Service にメトリックを送信します。Terraform スクリプトは、GKE クラスターをセットアップし、監視サービスを明示的に無効にします。メトリックがないため、セキュリティイベントを適切に検出し、これに迅速に応答することができなくなります。

例 1: 次の例は、monitoring_service を none に設定して GKE クラスターの監視サービスを無効にする Terraform 構成を示しています。


resource "google_container_cluster" "cluster-demo" {
    name               = "name-demo"
    location           = "us-central1-a"
    monitoring_service = "none"
    ...
}
