卷挂载不工作 Kubernetes 和 WSL 2 和 Docker

Question

我无法在 Docker 和 WSL 2 中运行的 Kubernetes 中使用 HostPath 正确挂载卷。在 Docker 中运行的 Kubernetes 中挂载卷时，这似乎是 WSL 2 问题。有人知道怎么修这个东西吗？

以下是步骤：

为我的应用程序将调试版本部署到 Kubernetes。使用 Kubernetes 扩展附加 Visual Studio Code 导航到我的应用程序的项目文件夹，该应用程序使用卷挂载 <= 问题就在这里

当您查看卷挂载时，什么也没有。

根据以下线程，wsl2 尚未正式支持 hostPath 卷。他们确实建议了一种解决方法，尽管我无法让它发挥作用。我发现前置/run/desktop/mnt/host/c似乎对我有用。

// C:\someDir\volumeDir
hostPath:
  path: /run/desktop/mnt/host/c/someDir/volumeDir
  type: DirectoryOrCreate
