GCP Terraform Misconfiguration: GKE Node Auto-Upgrade Disabled

Abstract

Terraform 組態停用了自動升級 Kubernetes 節點功能。

Explanation

依預設，GKE 會自動將 Kubernetes 節點升級到較新的穩定版本。可確保及時修補已知軟體漏洞的自動升級遭到停用。

範例 1：以下範例 Terraform 組態透過將 management 區塊中的 auto_upgrade 設定為 false 來停用 Kubernetes 節點的自動升級功能。


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