卷挂载不起作用Kubernetes和WSL 2和Docker

问题描述

我无法在Docker和WSL 2中运行的Kubernetes中使用HostPath正确装载卷.这似乎是在Docker中运行的Kubernetes中装载卷的WSL 2问题.有人知道如何解决这个问题吗?

I am unable to properly mount volumes using HostPath within Kubernetes running in Docker and WSL 2. This seems to be a WSL 2 issue when mounting volumes in Kubernetes running in Docker. Anyone know how to fix this?

以下是步骤:

为我的应用程序将调试版本部署到Kubernetes.使用Kubernetes扩展名附加Visual Studio Code导航到我的应用程序的项目文件夹，该文件夹是使用卷挂载< =问题在这里

Deploy debug build to Kubernetes for my app.Attach Visual Studio Code using the Kubernetes extensionNavigate to the project folder for my application that was attached using the volume mount <= Problem Right Here

当您查看卷挂载时，没有任何显示.

When you go and look at the volume mount nothing is there.

推荐答案

根据以下线程，wsl2尚未正式支持hostPath卷.他们确实提出了一种解决方法，尽管我无法使其正常工作.我发现前置/run/desktop/mnt/host/c似乎对我有用.

According to the following thread, hostPath volumes are not officially supported for wsl2, yet. They do suggest a workaround, though I had trouble getting it to work. I have found that prepending /run/desktop/mnt/host/c seems to work for me.

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