Kubernetes Misconfiguration: Missing API Server Authorization

YAML

Abstract

Kubernetes API 서버가 요청에 대해 권한 부여를 요구하지 않습니다.

Explanation

Kubernetes API 서버는 여러 권한 부여 모드 중 하나를 사용하여 요청에 권한을 부여할 수 있습니다. AlwaysAllow 모드에서 API 서버는 권한 부여 확인을 수행하지 않습니다. 이 모드는 모든 요청을 허용하기 때문입니다.

예제 1: 다음 구성은 AlwaysAllow를 권한 부여 모드 중 하나로 사용하여 Kubernetes API 서버를 시작합니다.


...
kind: Pod
...
spec:
  containers:
  - command:
    - kube-apiserver
    ...
    - --authorization-mode=...,AlwaysAllow,...
    ...
