PV及PVC实战

安装及配置NFS（参考本人博客）

创建NFS共享目录

mkdir -p /data/volumes/v{1,2,3,4,5,6,7,8,9,10}

新增共享目录

[root@k8smaster1 ~]# cat /etc/exports
/data/v1 *(rw,no_root_squash)

/data/volumes/v1 192.168.1.0/24(rw,no_root_squash)
/data/volumes/v2 192.168.1.0/24(rw,no_root_squash)
/data/volumes/v3 192.168.1.0/24(rw,no_root_squash)
/data/volumes/v4 192.168.1.0/24(rw,no_root_squash)
/data/volumes/v5 192.168.1.0/24(rw,no_root_squash)
/data/volumes/v6 192.168.1.0/24(rw,no_root_squash)
/data/volumes/v7 192.168.1.0/24(rw,no_root_squash)
/data/volumes/v8 192.168.1.0/24(rw,no_root_squash)
/data/volumes/v9 192.168.1.0/24(rw,no_root_squash)
/data/volumes/v10 192.168.1.0/24(rw,no_root_squash)
[root@k8smaster1 ~]#

启动共享

创建PV

[root@k8smaster1 pv]# cat pv-test.yaml 
apiVersion: v1
kind: PersistentVolume
metadata:
  name: v1
  labels:
    app: v1
spec:
  capacity: 
    storage: 1Gi
  accessModes: ["ReadWriteOnce"]
  nfs:
    server: 192.168.1.170
    path: /data/volumes/v1

---

apiVersion: v1
kind: PersistentVolume
metadata:
  name: v2
  labels:
    app: v2
spec:
  capacity:
    storage: 2Gi
  accessModes: ["ReadWriteMany"]
  nfs:
    server: 192.168.1.170
    path: /data/volumes/v1

---

apiVersion: v1
kind: PersistentVolume
metadata:
  name: v3
  labels:
    app: v3
spec:
  capacity:
    storage: 2Gi
  accessModes: ["ReadOnlyMany"]
  nfs:
    server: 192.168.1.170
    path: /data/volumes/v1

创建PVC

[root@k8smaster1 pv]# cat pvc-test.yaml 
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-v1
  labels:
    app: pvc-v1
spec:
  accessModes: ["ReadWriteOnce"]
  selector:
    matchLabels:
      app: v1
  resources:
    requests:
      storage: 1Gi

---

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-v2
  labels:
    app: v2
spec:
  accessModes: ["ReadWriteMany"]
  selector:
    matchLabels:
      app: v2
  resources:
    requests:
      storage: 2Gi

---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-v3
  labels:
    app: v3
spec:
  accessModes: ["ReadOnlyMany"]
  selector:
    matchLabels:
      app: v3
  resources:
    requests:
      storage: 2Gi

挂载Pod

[root@k8smaster1 pv]# cat pvc-pod.yaml 
apiVersion: v1
kind: Pod
metadata:
  name: pvc-v1
  labels:
    app: pvc-nginx
spec:
  containers:
  - name: nginx
    image: docker.io/library/nginx
    imagePullPolicy: IfNotPresent
    volumeMounts:
    - name: nginx-html
      mountPath: /usr/share/nginx/html/
    ports:
    - containerPort: 80
      protocol: TCP
  volumes:
  - name: nginx-html
    persistentVolumeClaim:
      claimName: pvc-v1
