GCP Terraform Misconfiguration: Insufficient GKE Cluster Monitoring

Abstract

이 Terraform 스크립트는 Google Kubernetes Engine 클러스터의 모니터링 서비스를 비활성화합니다.

Explanation

기본적으로 Google Kubernetes Engine(GKE) 클러스터는 Pod에서 Stackdriver Kubernetes Engine Monitoring Service로 메트릭을 보냅니다. 이 Terraform 스크립트는 GKE 클러스터를 설정하고 모니터링 서비스를 명시적으로 비활성화합니다. 메트릭이 없으면 보안 이벤트의 적절한 감지 및 신속한 대응에 저해됩니다.

예제 1: 다음 예제는 monitoring_service를 none으로 설정하여 GKE 클러스터의 모니터링 서비스를 비활성화하는 Terraform 구성을 보여줍니다.


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