kubernetes PodSecurityPolicy设置为runAsNonRoot，容器具有runAsNonRoot，图像具有非数字用户（appuser），无法验证用户是否为非根用户

kubernetes PodSecurityPolicy设置为runAsNonRoot，Pod未在获取错误后启动错误：容器具有runAsNonRoot且映像具有非数字用户（appuser），无法验证用户是否为非根用户

我们正在docker容器中创建用户（appuser）uid->999和组（appgroup）gid->999，并使用该用户启动容器

但是豆荚的制造是错误的

.

以下是验证结果：

case uid == nil && len(username) > 0:
    return fmt.Errorf("container has runAsNonRoot and image has non-numeric user (%s), cannot verify user is non-root", username)

以下是评论的全文：

// Verify RunAsNonRoot. Non-root verification only supports numeric user.
if err := verifyRunAsNonRoot(pod, container, uid, username); err != nil {
    return nil, cleanupAction, err
}

如您所见，在您的案例中，出现该消息的唯一原因是

uid==nil

。根据源代码中的注释，我们需要设置一个数字用户值

因此，对于UID=999的用户，您可以在pod定义中执行此操作：

谢谢。安东：信息太多了。。我们将uid设置为999，用户名设置为appuser:）。。当用户成为999后，它工作了：）。。

securityContext:
    runAsUser: 999
