Kubernetes Misconfiguration: Missing NodeRestriction Admission Controller

YAML

Abstract

Kubernetes API 서버를 시작하는 이 명령은 NodeRestriction 승인 컨트롤러를 활성화하지 않습니다.

Explanation

Kubernetes API 서버에 대해 항상 NodeRestriction 승인 컨트롤러를 활성화하십시오. NodeRestriction 승인 컨트롤러는 모든 Kubelet이 해당 Node 및 Pod 개체를 수정하는 것을 제한하며 민감한 시스템 개체에 대한 액세스를 거부합니다. 이는 손상된 노드가 Kubernetes 클러스터의 다른 노드에 대한 권한을 얻는 것을 방지합니다.

예제 1: 다음 Pod 정의는 NodeRestriction 승인 컨트롤러를 활성화하지 않고 Kubernetes API 서버를 시작합니다.


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