pod使用volumes情况

1.首先创建nfs服务

apiVersion: v1
kind: Pod
metadata:
  name: nginx-demo
spec:
  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: v1
kind: PersistentVolume
metadata:
  name: pv001
  labels:
    app: pv0011
spec:
  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: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc1
spec: 
  volumeMode: Filesystem
  volumeName: pv002
  accessModes:
    - ReadWriteOnce
  storageClassName: slow
  resources:
    requests:
      storage: 1Gi

pod上面引用 pvc

apiVersion: v1
kind: Pod
metadata:
  name: nginx-demo
spec:
  containers:
  - name: nginx
    image: nginx
    imagePullPolicy:  Never
    ports:
    - containerPort: 80
    volumeMounts:
    - name: nfs1
      mountPath: /opt/pvc
  volumes:
  - name: nfs1
    persistentVolumeClaim: 
      claimName: pvc1
