Kubernetes Minikube与本地永久存储

我目前正在尝试在Minikube上部署以下内容。 我使用配置文件将一个主机路径用作minikube节点上的永久性存储。

apiVersion: v1
kind: PersistentVolume
metadata:
  name: "pv-volume"
spec:
  capacity:
    storage: "20Gi"
  accessModes:
    - "ReadWriteOnce"
  hostPath:
    path: /data
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: "orientdb-pv-claim"
spec:
  accessModes:
    - "ReadWriteOnce"
  resources:
    requests:
      storage: "20Gi"
---
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: orientdbservice 
spec:
  #replicas: 1
  template:
    metadata:
     name: orientdbservice
     labels:
       run: orientdbservice
       test: orientdbservice
    spec:
      containers:
        - name: orientdbservice
          image: orientdb:latest
          env:
           - name: ORIENTDB_ROOT_PASSWORD
             value: "rootpwd"
          ports:
          - containerPort: 2480
            name: orientdb
          volumeMounts:
          - name: orientdb-config
            mountPath: /data/orientdb/config
          - name: orientdb-databases
            mountPath: /data/orientdb/databases 
          - name: orientdb-backup
            mountPath: /data/orientdb/backup
      volumes:
          - name: orientdb-config
            persistentVolumeClaim:
              claimName: orientdb-pv-claim
          - name: orientdb-databases
            persistentVolumeClaim:
              claimName: orientdb-pv-claim
          - name: orientdb-backup
            persistentVolumeClaim:
              claimName: orientdb-pv-claim
---
apiVersion: v1
kind: Service
metadata:
  name: orientdbservice
  labels:
    run: orientdbservice
spec:
  type: NodePort
  selector:
    run: orientdbservice
  ports:
   - protocol: TCP
     port: 2480
     name: http

结果如下

#kubectl get pv

  4h        1m      37  kubelet, minikube           Warning     FailedSync  Error syncing pod

我看到以下错误

Unable to mount volumes for pod,timeout expired waiting for volumes to attach/mount for pod

在我的节点上创建Persistent Volume和PersistentVolumeClaim的方式中有不正确的地方。

minikube version: v0.20.0

感谢所有的帮助

你的配置没问题。

在minikube v0.24.0 ， minikube v0.25.0和minikube v0.26.1下测试没有任何问题。

请记住， minikube正在积极开发中 ，特别是如果你在windows下，就像他们说的实验性软件一样 。

更新到更新版本的minikube并重新部署它。 这应该可以解决问题。

您可以使用minikube update-check命令minikube update-check ，结果如下所示：

$ minikube update-check
CurrentVersion: v0.25.0
LatestVersion: v0.26.1

要升级minikube，只需输入minikube delete ，删除当前的minikube安装并按照说明下载新版本。

$ minikube delete
There is a newer version of minikube available (v0.26.1).  Download it here:
https://github.com/kubernetes/minikube/releases/tag/v0.26.1

To disable this notification, run the following:
minikube config set WantUpdateNotification false
Deleting local Kubernetes cluster...
Machine deleted.

对于provisioner: k8s.io/minikube-hostpath ，提供者provisioner: k8s.io/minikube-hostpath中的minikube不起作用。

所以：

apiVersion: storage.k8s.io/v1
kind: StorageClass

provisioner: docker.io/hostpath

          ports:
