GCP Terraform Misconfiguration: Insufficient GKE Cluster Monitoring

Abstract

Terraform 脚本禁用了 Google Kubernetes Engine 群集的监控服务。

Explanation

默认情况下，Google Kubernetes Engine (GKE) 群集将指标从 Pod 发送到 Stackdriver Kubernetes Engine 监控服务。Terraform 脚本设置 GKE 群集并显式禁用监控服务。缺少指标会破坏对安全事件的正确检测和及时响应。

示例 1：以下示例显示的 Terraform 配置通过将 monitoring_service 设置为 none 禁用了 GKE 群集的监控服务。


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