Kubernetes Misconfiguration: Missing NodeRestriction Admission Controller

Abstract
用于启动 Kubernetes API 服务器的命令不会启用 NodeRestriction 准入控制器。
Explanation
始终启用 Kubernetes API 服务器的 NodeRestriction 准入控制器。NodeRestriction 准入控制器限制每个 Kubelet 修改其 Node 和 Pod 对象，且拒绝对敏感系统对象的访问。这可以防止任何受损节点获取 Kubernetes 群集的其他节点上的权限。

示例 1：以下 Pod 定义启动了未启用 NodeRestriction 准入控制器的 Kubernetes API 服务器。

apiVersion: v1
kind: Pod
...
spec:
  containers:
  - command:
    - kube-apiserver
    ...
    - --enable-admission-plugins=PodSecurityPolicy
    ...
