enforce-policy-as-code

Implement declarative policy enforcement using OPA Gatekeeper or Kyverno for Kubernetes resource validation and mutation.

Expected: Policy engine pods running with multiple replicas. CRDs installed (ConstraintTemplate, Constraint for Gatekeeper; ClusterPolicy, Policy for Kyverno). Validating/mutating webhooks active. Audit controller running.

Expected: ConstraintTemplates/ClusterPolicies created successfully. Constraints show status "True" for enforcement. No errors in policy definitions. Webhook begins evaluating new resources against policies.

使用 OPA Gatekeeper 或 Kyverno 實施策略即程式碼實施，以根據組織策略驗證和變更 Kubernetes 資源。涵蓋約束範本、存取控制、稽核模式、報告違規以及與 CI/CD 管道整合以進行左移策略驗證。在執行資源配置標準、防止安全性錯誤配置（例如特權容器）、確保部署前合規性、標準化命名約定或根據政策審核現有叢集資源時使用。 來源：pjt222/development-guides。
