Kubernetes在Mac Docker桌面上的持久卷存储位置在哪里？

Question

我不确定我是否有配置错误，或者我只是不知道在哪里查找，但我似乎找不到我的文件存储这些配置的地方

apiVersion: v1
kind: PersistentVolume
metadata:
  name: tmp-storage
spec:
  storageClassName: manual
  capacity:
    storage: 2Gi
  accessModes:
    - ReadWriteMany
  hostPath:
    path: /tmp/netes
    type: Directory

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: tmp-storage-claim
spec:
  storageClassName: manual
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 1Gi

spec:
  volumes:
    - name: abcd
      persistentVolumeClaim:
       claimName: tmp-storage-claim 

  containers:
    ...
    volumeMounts:
      - mountPath: '/tmp'
        name: abcd

我的计算机/tmp内也没有任何东西

我还尝试在/users/username/.docker/volumes/中查找，但该位置没有volumes目录

下面是我在Mac上找到它的方法：

1.创建PV、PVC、Deployment。我刚刚将PVspec.hostpath.type更改为directoryorcreate

2.使用pod shell在卷上创建一个文件：

kubeclt exec -ti the-deployment-pod-name-here -- touch /tmp/somefile2.txt

docker run -it --rm --privileged --pid=host alpine:edge nsenter -t 1 -m -u -n -i sh

/ # find / -name somefile2.txt
/var/lib/mount-docker-cache/entries/docker.tar/a08ee16361132af943875aee79aae165cdbfaf0d203ee97fe9d61d29e307aceb/containers/services/docker/tmp/upper/tmp/netes/somefile2.txt
/var/lib/mount-docker-cache/entries/docker.tar/a08ee16361132af943875aee79aae165cdbfaf0d203ee97fe9d61d29e307aceb/containers/services/docker/rootfs/tmp/netes/somefile2.txt
/var/lib/mount-docker-cache/entries/services.tar/bbec751ae945082378b0b2d4a7c6e32f9c35164315587914a95acc4bee8df1ff/containers/services/docker/tmp/upper/tmp/netes/somefile2.txt
/var/lib/mount-docker-cache/entries/services.tar/bbec751ae945082378b0b2d4a7c6e32f9c35164315587914a95acc4bee8df1ff/containers/services/docker/rootfs/tmp/netes/somefile2.txt
/containers/services/docker/tmp/upper/tmp/netes/somefile2.txt
/containers/services/docker/rootfs/tmp/netes/somefile2.txt

/containers/services/docker/tmp/upper
/containers/services/docker/rootfs

+ PV hostPath: /tmp/netes
+ filename: somefile2.txt

注意:hostpathPV文件位于DockerVM文件系统中。我还没有找到一种方法来共享Mac文件夹到PV在DockerDesktop Kubernetes吊舱目前。

注意2:DockerDesktop Kubernetes没有在PV和PVC中指定StorageClass，而是指定了一个默认存储类，在我的示例中是HostPath，并在DockerVM临时位置为PV生成一个文件夹：

/var/lib/k8s-pvs/tmp-storage-claim/pvc-dafbcdf6-a3e8-47cc-af1a-cf740d8ffcd0/somefile2.txt
