windows - Kubernetes 如何在 wsl2 支持的环境中正确挂载 Windows 路径

Question

我有一个以这种方式运行良好的本地镜像:docker run -p 8080:8080 -v C:\Users\moritz\Downloads\1\imageService\examples1:/images -v C:\Users\moritz\entwicklung\projekte\imageCluster\logs:/logs imageservice

现在我希望它作为 Kubernetes(使用 Docker-for-Windows v1.19.7 内置)部署运行:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: image-service
spec:
  selector:
    matchLabels:
      app: image-service
  template:
    metadata:
      labels:
        app: image-service
    spec:
      containers:
      - name: image-service
        image: "imageservice"
        resources:
          limits:
            cpu: "0.9"
            memory: "1Gi"
        ports:
        - name: http
          containerPort: 8080
        volumeMounts:
          - mountPath: /images
            name: image-volume
          - mountPath: /logs
            name: log-volume  
      volumes:
        - name: image-volume
          hostPath:
            path: "c:\\Users\\moritz\\Downloads\\1\\imageService\\examples1"
            type: Directory
        - name: log-volume
          hostPath:
            path: /mnt/c/Users/moritz/entwicklung/projekte/imageCluster/logs
            type: Directory

如您所见，我尝试了不同的方法在 Windows 机器上设置我的主机路径，但我总是得到:

  Warning  FailedMount  0s (x4 over 4s)  kubelet            MountVolume.SetUp failed for volume "log-volume" : hostPath type check failed: /mnt/c/Users/moritz/entwicklung/projekte/imageCluster/logs is not a directory
  Warning  FailedMount  0s (x4 over 4s)  kubelet            MountVolume.SetUp failed for volume "image-volume" : hostPath type check failed: c:\Users\moritz\Downloads\1\imageService\examples1 is not a directory 

我还尝试了其他变体(对于两者):

• C:\Users\moritz\entwicklung\projekte\imageCluster\logs
• C:/Users/moritz/entwicklung/projekte/imageCluster/logs

那么如何正确设置这些windows主机路径。 (下一步是将它们设置为环境变量。)

小更新:

删除 type: Directory 有助于消除错误，并且 pod 正在启动但挂载不工作。如果我“查看”/images 中的容器，我看不到主机上的图像，并且在容器/logs 中包含预期文件时，我在日志挂载中看不到任何日志。

同时我也试过了(没用)

• /host_mnt/c/...
• /C/用户/...
• //C/用户/...

Answer 1

如前所述here ，您可以使用下面的 hostPath 使其在 wsl2 上工作。

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

您还可以使用一个示例。

apiVersion: v1
kind: Pod
metadata:
  name: test-localpc
spec:
  containers:
  - name: test-webserver
    image: ubuntu:latest
    command: ["/bin/sh"]
    args: ["-c", "apt-get update && apt-get install curl -y && sleep 600"]
    volumeMounts:
    - mountPath: /run/desktop/mnt/host/c/aaa
      name: mydir
    - mountPath: /run/desktop/mnt/host/c/aaa/1.txt
      name: myfile
  volumes:
  - name: mydir
    hostPath:
      # Ensure the file directory is created.
      path: /run/desktop/mnt/host/c/aaa
      type: DirectoryOrCreate
  - name: myfile
    hostPath:
      path: /run/desktop/mnt/host/c/aaa/1.txt
      type: FileOrCreate
