卷挂载不起作用 Kubernetes 和 WSL 2 和 Docker [英] Volume mounts not working Kubernetes and WSL 2 and Docker
问题描述
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?
步骤如下:
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，该文件夹使用卷挂载 <= Problem Right Here
Deploy debug build to Kubernetes for my app. Attach Visual Studio Code using the Kubernetes extension Navigate to the project folder for my application that was attached using the volume mount <= Problem Right Here
当你去查看卷挂载时，什么都没有.
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，尽管我无法让它发挥作用.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:someDirvolumeDir
hostPath:
path: /run/desktop/mnt/host/c/someDir/volumeDir
type: DirectoryOrCreate
