界: Encapsulation

封裝是要劃定清楚的界限。在網頁瀏覽器中，這可能意味著確保您的行動程式碼不會被其他行動程式碼濫用。在伺服器上，這可能意味著區分經過驗證的資料與未經驗證的資料、區分一個使用者的資料與另一個使用者的資料，或區分允許使用者查看的資料與不允許查看的資料。

Kubernetes Misconfiguration: Default Namespace

YAML

Abstract

避免使用 Kubernetes 預設命名空間。

Explanation

Kubernetes 命名空間會將一個叢集劃分為多個可管理的區塊。命名空間為名稱提供了一個範圍，簡化將各種原則指定給叢集子區段。依預設，Kubernetes 會將資源配置給 default 命名空間。使用非預設命名空間的其他命名空間可以降低錯誤或惡意活動的影響。

範例 1：以下組態將資源的命名空間設定為 default。


...
kind: ...
metadata:
...
namespace: default
spec:
...
