Kubernetes Misconfiguration: Missing ServiceAccount Admission Controller

YAML

Abstract

用于启动 Kubernetes API 服务器的命令会禁用 ServiceAccount 准入控制器。

Explanation

Kubernetes 区分了用户帐户和服务帐户的概念，后者用于在 Pod 中运行进程。ServiceAccount 准入控制器会自动执行服务帐户管理。ServiceAccount 准入控制器的优点是可通过自动凭据轮换减少访问令牌泄露风险，并省去存储机密的必要。ServiceAccount 准入控制器默认处于启用状态，但已被故意禁用。

示例 1：以下 Pod 定义启动 Kubernetes API 服务器并禁用 ServiceAccount 准入控制器。


apiVersion: v1
kind: Pod
...
spec:
  containers:
  - command:
    - kube-apiserver
    ...
    - --disable-admission-plugins=ServiceAccount,PodNodeSelector
    ...
