GCP Terraform Misconfiguration: GKE Node Auto-Upgrade Disabled

Abstract

Terraform 配置禁用了 Kubernetes 节点的自动升级。

Explanation

默认情况下，GKE 会自动将 Kubernetes 节点升级至更新的稳定版本。能够确保及时修补已知软件漏洞的自动升级已被禁用。

示例 1：以下示例 Terraform 配置通过在 management 块中将 auto_upgrade 设置为 false，禁用了 Kubernetes 节点的自动升级。


resource "google_container_node_pool" "node_pool_demo" {
...
  management {
    auto_upgrade = false
    ...
  }
...
}
