Minio数据在重新启动后不会持续存在

Question

我在Ubuntu桌面上的Kubernetes上部署了Minio。它工作得很好，除了每当我重新启动机器时，存储在Minio中的所有东西都神秘地消失了(如果我创建了几个存储桶中的文件，那么在重新启动后我就会回到一个完全空白的石板上-这些存储桶和它们的所有文件都完全消失了)。

当我设置Minio时，我在Kubernetes中创建了一个持久卷，该卷挂载到一个文件夹(/mnt/minio/minio -我在/mnt/minio上挂载了一个4 TB的硬盘，里面有一个名为minio的文件夹)。

下面是我应用来部署我的minio安装的yaml文件：

kind: PersistentVolume
apiVersion: v1
metadata:
  name: minio-pv-volume
  labels:
    type: local
spec:
  storageClassName: manual
  capacity:
    storage: 100Gi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: "/mnt/minio/minio"

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: minio-pv-claim
  labels:
    app: minio-storage-claim
spec:
  storageClassName: manual
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 99Gi

apiVersion: apps/v1 #  for k8s versions before 1.9.0 use apps/v1beta2  and before 1.8.0 use extensions/v1beta1
kind: Deployment
metadata:
  # This name uniquely identifies the Deployment
  name: minio-deployment
spec:
  selector:
    matchLabels:
      app: minio
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        # Label is used as selector in the service.
        app: minio
    spec:
      # Refer to the PVC created earlier
      volumes:
      - name: storage
        persistentVolumeClaim:
          # Name of the PVC created earlier
          claimName: minio-pv-claim
      containers:
      - name: minio
        # Pulls the default Minio image from Docker Hub
        image: minio/minio:latest
        args:
        - server
        - /storage
        env:
        # Minio access key and secret key
        - name: MINIO_ACCESS_KEY
          value: "minio"
        - name: MINIO_SECRET_KEY
          value: "minio123"
        ports:
        - containerPort: 9000
          hostPort: 9000
        # Mount the volume into the pod
        volumeMounts:
        - name: storage # must match the volume name, above
          mountPath: "/mnt/minio/minio"

apiVersion: v1
kind: Service
metadata:
  name: minio-service
spec:
  type: LoadBalancer
  ports:
    - port: 9000
      targetPort: 9000
      protocol: TCP
  selector:
    app: minio

Answer 1

您需要在容器/mnt/minio/minio/；的挂载目录下挂载容器的/storage目录

args:

    - server
    - /mnt/minio/minio/storage

但请考虑使用StatefulSet进行部署，这样当pod重新启动时，它将保留以前pod的所有内容。
