pod使用volumes情况

1.首先创建nfs服务

apiVersion: v1kind: Podmetadata:  name: nginx-demospec:  containers:  - name: nginx    image: nginx    ports:    - containerPort: 80    volumeMounts:    - name: nfs1      mountPath: /opt/wwwroot      readOnly: true  volumes:  - name: nfs1    nfs:      path: /opt/wwwroot     #nfs暴露除了的目录  showmount -e       server: 192.168.8.131    #nfs的服务器

使用nfs创建pv

apiVersion: v1kind: PersistentVolumemetadata:  name: pv001  labels:    app: pv0011spec:  capacity:     storage: 1Gi  volumeMode: Filesystem  accessModes:    - ReadWriteOnce  storageClassName: slow  persistentVolumeReclaimPolicy: Recycle  nfs:     server: 192.168.8.131    path: /opt/wwwroot1

如果某个Pod想申请某种类型的PV，则首先需要定义一个 pvc

PersistentVolumeClaim对象apiVersion: v1kind: PersistentVolumeClaimmetadata:  name: pvc1spec:   volumeMode: Filesystem  volumeName: pv002  accessModes:    - ReadWriteOnce  storageClassName: slow  resources:    requests:      storage: 1Gi

pod上面引用 pvc

apiVersion: v1kind: Podmetadata:  name: nginx-demospec:  containers:  - name: nginx    image: nginx    imagePullPolicy:  Never    ports:    - containerPort: 80    volumeMounts:    - name: nfs1      mountPath: /opt/pvc  volumes:  - name: nfs1    persistentVolumeClaim:       claimName: pvc1
