NFS服务器

[root@V71 nfs_test]# cat /etc/exports
#/nfs_test 192.168.0.0/16(rw,no_root_squash,no_all_squash,sync)
/nfs_test 192.168.0.0/16(rw,sync,all_squash)
/nfs2 192.168.0.0/16(rw,sync,all_squash)
/nfs3 192.168.0.0/16(rw,sync,all_squash)

[root@V71 nfs_test]# service nfs restart
Redirecting to /bin/systemctl restart nfs.service

配置两个PV,两个PVC,并分别对应，红色字体部份是绑定的键值

[root@k8s1 pv]# cat pv2.yml 
apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv2
  labels:
    pv: two
spec:
  capacity:
    storage: 200Mi
  accessModes:
    - ReadWriteMany
  nfs:
    server: 192.168.137.1
    path: /nfs2
[root@k8s1 pv]# cat pvc2.yml 
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc2
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 150Mi
  selector:
    matchLabels:
      pv: two
[root@k8s1 pv]# cat pv3.yml 
apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv3
  labels:
    pv: three
spec:
  capacity:
    storage: 200Mi
  accessModes:
    - ReadWriteMany
  nfs:
    server: 192.168.137.1
    path: /nfs3
[root@k8s1 pv]# cat pvc3.yml 
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc3
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 150Mi
  selector:
    matchLabels:
      pv: three

创建PV,PVC

[root@k8s1 pv]# kubectl create -f pv2.yml 
persistentvolume "pv2" created

[root@k8s1 pv]# kubectl create -f pvc2.yml 
persistentvolumeclaim "pvc2" created
[root@k8s1 pv]# kubectl create -f pv3.yml 
persistentvolume "pv3" created
[root@k8s1 pv]# kubectl create -f pvc3.yml 
persistentvolumeclaim "pvc3" created

此时查看PV，已经精确对应了

[root@k8s1 pv]# kubectl get pv
NAME      CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS    CLAIM          STORAGECLASS   REASON    AGE
pv1       2Gi        RWO            Recycle          Bound     default/pvc1                            16h
pv2       200Mi      RWX            Retain           Bound     default/pvc2                            58s
pv3       200Mi      RWX            Retain           Bound     default/pvc3                            17s
