Kubernetes Misconfiguration: Shared Service Account Credentials

YAML

Abstract

Kubernetes 컨트롤러 관리자를 시작하는 이 명령은 컨트롤러 간에 서비스 계정 자격 증명을 공유하는 것을 허용합니다.

Explanation

Kubernetes 컨트롤러 관리자를 시작하는 명령에 --use-service-account-credentials=true 플래그가 포함되어 있지 않기 때문에 서비스 계정 자격 증명이 컨트롤러 간에 공유됩니다. 이 플래그는 컨트롤러 관리자가 별도의 서비스 계정을 사용하여 각 컨트롤러를 시작하도록 지시합니다. RBAC(Role-Based Access Control)와 함께 사용하면 각 컨트롤러가 해당 작업을 수행하는 데 필요한 최소 권한으로 실행됩니다.

예제 1: 다음 구성은 --use-service-account-credentials 플래그 없이 Kubernetes 컨트롤러 관리자를 시작합니다.
