## 定义
|
||||
Kubernetes Service Account(服务账户)是 Pod 用于身份验证到 Kubernetes API Server 的机制。每个 Pod 关联一个服务账户,默认使用 default 服务账户。
|
||||
|
||||
## 安全最佳实践
|
||||
- 禁用自动挂载(`automountServiceAccountToken: false`)
|
||||
- 使用私有服务账户而非默认账户
|
||||
- 通过 Role/RoleBinding 最小化权限
|
||||
- 定期轮换服务账户凭据
|
||||
|
||||
## 关联安全配置
|
||||
- `automountServiceAccountToken`:控制是否自动挂载服务账户令牌
|
||||
- `imagePullSecrets`:用于私有镜像仓库认证
