Kubernetes Admission 異常模式與復原防線

當 Webhook 驗證服務異常時,系統面臨保全合規與保障可用性的取捨。本文解析 Kubernetes Admission Control 的行為邊界:Fail 模式會阻斷匹配請求但確保政策強制力,Ignore 模式則放行請求但留下未攔截的配置偏差。同時探討 Gatekeeper 在極端條件下的寫入僵局與復原路徑。

Kubernetes Admission Failure Modes and Recovery Safeguards

When a Webhook validation service fails, the system faces a trade-off between preserving security compliance and ensuring availability. This article analyzes the behavioral boundaries of Kubernetes Admission Control: Fail mode blocks matching requests but ensures policy enforcement, whereas Ignore mode permits requests but leaves configuration drift that is not intercepted.
