您可以使用 Compliance Operator 策略在受管集群上安装 Compliance Operator。Compliance operator 策略在 Red Hat Advanced Cluster Management 中作为 Kubernetes 配置策略创建。OpenShift Container Platform 支持 Compliance operator 策略。

注： Compliance operator 策略依赖于 OpenShift Container Platform Compliance Operator，它不受 IBM Power 或 IBM Z 架构的支持。如需有关 Compliance Operator 的更多信息，请参阅 OpenShift Container Platform 文档中的了解 Compliance Operator 部分。

创建合规 Operator 策略时，会创建以下资源：

安装 compliance operator 策略后，会创建以下 pod：compliance-operator、ocp4 和 rhcos4。请参阅 policy-compliance-operator-install.yaml 示例。

当您创建 E8 扫描策略时，会创建以下资源：

注： 支持自动补救。将补救操作设置为 enforce 以创建 ScanSettingBinding 资源。

请参阅 policy-compliance-operator-e8-scan.yaml 示例。如需更多信息，请参阅管理安全策略。注： 删除 E8 策略后，它会从目标集群或集群中移除。

创建 OpenShift CIS 扫描策略时，会创建以下资源：

请参阅 policy-compliance-operator-cis-scan.yaml 文件示例。有关创建策略的更多信息，请参阅管理安全策略。

在创建容器安全 Operator 策略时，它会涉及以下策略：

请参阅 policy-imagemanifestvuln.yaml。如需更多信息，请参阅管理安全策略。请参阅 Kubernetes 配置策略控制器，以查看配置控制器监控的其他配置策略。

当您将策略设置为 hub 集群时，会安装以下 OpenShift Platform Plus 组件：
