K8s 安装 persistentVolume 失败，"timed out waiting for the condition" on docker-desktop

Question

当尝试将一个 pod 绑定到托管在另一个 pod 上的 NFS persistentVolume 时，使用 docker-desktop 时无法挂载。即使使用完全相同的 YAML，它在其他地方也能完美运行。

错误：

以及emptyDir我也试过hostPath。此设置以前有效，我不确定自从它停止后我更改了什么。

将我的 Docker for Windows 安装从 4.0.1 更新到 4.1.1 已经解决了这个问题。
