mysql - 如何使用本地持久卷创建mysql服务以将数据存储在Windows本地计算机上

Question

我希望当我重新启动计算机时，mysql pod不会删除所有mysql数据。
我应该能够将数据存储在计算机中，因此当我重新启动计算机并且mysql pod再次启动时，数据库仍然存在。
这是我的yaml:
storage-class.yaml

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer

mysql-pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: mysql-pv-volume
  labels:
    type: local
spec:
  capacity:
    storage: 20Gi
  accessModes:
    - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  volumeMode: Filesystem
  storageClassName: local-storage
  local:
    path: "C:\\mysql-volume" #2 \ for escape characters right?
  nodeAffinity:
    required:
      nodeSelectorTerms:
      - matchExpressions:
        - key: kubernetes.io/hostname
          operator: In
          values:
          - docker-desktop
  #hostPath:
   # path: /mysql-volume
    #type: DirectoryOrCreate

  name: mysql-pv-claim
  labels:

  accessModes:

    requests:
      storage: 20Gi

mysql-deployment.yaml

apiVersion: v1
kind: Service
metadata:
  name: mysql
  labels:
    app: mysql
spec:

    port: 3306
    nodePort: 30001
  selector:        
    app: mysql
  type: NodePort

        name: mysql
        env:
        - name: MYSQL_ROOT_PASSWORD
          valueFrom:
            secretKeyRef:
              name: db-secret
              key: mysql-root-password
        - name: MYSQL_USER
          valueFrom:
            secretKeyRef:
              name: db-secret
              key: mysql-user
        - name: MYSQL_PASSWORD
          valueFrom:
            secretKeyRef:
              name: db-secret
              key: mysql-password
        ports:
        - containerPort: 3306
          name: mysql
        volumeMounts:
        - name: mysql-persistent-storage
          mountPath: /var/lib/mysql
      volumes:
      - name: mysql-persistent-storage
        persistentVolumeClaim:
          claimName: mysql-pv-claim

尝试过之后，我得到的第一个错误是:

MountVolume.NewMounter initialization failed for volume "mysql-pv-volume" : path "C:\\mysql-volume" does not exist

由于我正在使用Windows，我猜这是正确的路径吗？我使用2“”作为转义字符，也许问题出在路径上，但不确定。如果是的话，如何在Windows计算机上提供本地路径？
然后我将 local: path:更改为 /opt并出现以下错误:

initialize specified but the data directory has files in it.

但是如果我将 mountPath: /var/lib/mysql更改为 mountPath: /var/lib/mysql-test它可以正常工作，但不符合预期(重新启动计算机后保存数据)。
即使删除了PV，PVC和MYSQL部署/服务，该错误仍然不断出现。
我什至使用docker命令删除了卷，以防万一，将我的mysql自定义镜像更改为“mysql:5.7”，但是出现了相同的 initialize specified but the data directory has files in it.。
即使我卸下 pod ，怎么办？ mountPath是容器路径，因此数据应消失。
以及如何在persistentVolume中给出本地路径？
谢谢你的时间!
编辑:忘记告诉我我已经看到了: How to create a mysql kubernetes service with a locally mounted data volume?
我搜索了很多，但没有运气

我终于解决了这个问题...
@Jakub回答了initialize specified but the data directory has files in it.的问题MountVolume.NewMounter initialization failed for volume "mysql-pv-volume" : path "C:\\mysql-volume" does not exist...。由于这个愚蠢的问题，我什至不敢相信花费的时间...
正确的路径是:path: /c/mysql-volume之后，一切都按预期工作!
