<p>I'm fighting since many hours setting my k8s pods on my <code>minikube</code> single node, at persistent volume creation stage.</p>

<p>This command always ends with error, even if I copy/paste the example spec from <code>kubernetes</code> documentation :</p>

<pre><code>$kubectl apply -f pv-volume.yml
</code></pre>

<blockquote>
  <p>error: SchemaError(io.k8s.api.core.v1.ScaleIOVolumeSource): invalid
  object doesn't have additional properties</p>
</blockquote>

<pre><code>$cat pv-volume.yml
kind: PersistentVolume
apiVersion: v1
metadata:
  name: task-pv-volume
  labels:
    type: local
spec:
  storageClassName: manual
  capacity:
    storage: 10Gi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: "/mnt/data"
</code></pre>

<p>I can't figure out why kubectl obliges me to specify <code>ScaleIO</code> in my spec, while I'm using local volume.</p>

<p>I've the same error specifying <code>storagaClassName</code> to <code>standard</code></p>

<p>Any idea about what can be the problem?</p>

<p>My versions :</p>

<pre><code>$minikube version
minikube version: v1.0.0

$kubectl version
Client Version: version.Info{Major:"1", Minor:"10", GitVersion:"v1.10.11", GitCommit:"637c7e288581ee40ab4ca210618a89a555b6e7e9", GitTreeState:"clean", BuildDate:"2018-11-26T14:38:32Z", GoVersion:"go1.9.3", Compiler:"gc", Platform:"darwin/amd64"}

<p>In minikube , the dynamic provisioner is already there by default , you just need to create persistent volume claims using that Class.</p>

<pre><code>C02W84XMHTD5:Downloads iahmad$ minikube start

<p>so for th data persistence to host , you just need a volume claim and use it on your kubernetes deployment.</p>

<p>example mysql volume claim using the built in minikube storage class.</p>

<pre><code>kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: mysql-volumeclaim
  annotations:
    volume.beta.kubernetes.io/storage-class: standard
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
</code></pre>

<p>Usage inside mysql deployment:</p>

<pre><code>apiVersion: apps/v1
kind: Deployment
metadata:
  name: mysql
  labels:
    app: mysql
spec:
  replicas: 1
  selector:
    matchLabels:
      app: mysql
  template:
    metadata:
      labels:
        app: mysql
    spec:
      containers:
        - image: mysql:5.6
          name: mysql
          env:
            - name: MYSQL_ROOT_PASSWORD
              valueFrom:
                secretKeyRef:
                  name: mysql
                  key: password
          ports:
            - containerPort: 3306
              name: mysql
          volumeMounts:
            - name: mysql-persistent-storage
              mountPath: /var/lib/mysql
      volumes:
        - name: mysql-persistent-storage
          persistentVolumeClaim:
            claimName: mysql-volumeclaim
</code></pre>
