7.2. 默认准入插件
OpenShift Dedicated 4 中启用了默认的验证和准入插件。这些默认插件有助于基本的 control plane 功能，如入口策略、集群资源限制覆盖和配额策略。
重要
不要在默认项目中运行工作负载或共享对默认项目的访问权限。为运行核心集群组件保留默认项目。
以下默认项目被视为具有高度特权：default, kube-public, kube-system, openshift, openshift-infra, openshift-node，其他系统创建的项目的标签 openshift.io/run-level 被设置为 0 或 1。依赖于准入插件（如 pod 安全准入、安全性上下文约束、集群资源配额和镜像引用解析）的功能无法在高特权项目中工作。
以下列表包含默认准入插件：
