+# Pod Security Standards 部署指南
+
+> **版本**: K4.3
+> **用途**: Kubernetes 內建安全機制
+> **建立日期**: 2026-03-29 (台北時間)
+
+---
+
+## 1. 部署 Namespace Labels
+
+```bash
+# 在 K3s Master (192.168.0.120) 執行
+kubectl apply -f k8s/pod-security/namespace-labels.yaml
+
+# 或從本機透過 kubeconfig
+kubectl --kubeconfig=/path/to/k3s.yaml apply -f k8s/pod-security/namespace-labels.yaml
+```
+
+## 2. 驗證
+
+```bash
+# 檢查 namespace labels
+kubectl get ns -o custom-columns='NAME:.metadata.name,ENFORCE:.metadata.labels.pod-security\.kubernetes\.io/enforce'
+
+# 預期結果:
+# awoooi-prod         baseline
+# kube-state-metrics  baseline
+# kured               privileged
+# descheduler         restricted
+# velero              baseline
+# argocd              baseline
+```
+
+## 3. PSS 級別說明
+
+| 級別 | 說明 | 適用場景 |
+|------|------|---------|
+| `privileged` | 無限制 | Kured (hostPID + 重啟) |
+| `baseline` | 基本限制 | 大多數應用 |
+| `restricted` | 最嚴格 | 無特權需求的工具 |
+
+## 4. 標籤說明
+
+| 標籤 | 作用 |
+|------|------|
+| `enforce` | 違反時拒絕 Pod |
+| `warn` | 違反時發出警告 |
+| `audit` | 記錄到審計日誌 |
+
+## 5. 驗證 Pod 合規
+
+```bash
+# 測試 Pod 是否合規
+kubectl auth can-i create pod --namespace=awoooi-prod --as=system:serviceaccount:default:default
+
+# 檢查是否有警告
+kubectl get events -n awoooi-prod --field-selector reason=FailedCreate
+```
