k8s安装nfs共享存储卷

在k8s中安装NFS共享存储卷的步骤如下：
1. 在k8s集群的每个节点上安装NFS客户端依赖：
`sudo apt-get install nfs-common`
2. 配置NFS服务器，可以在一台独立的虚拟机上进行配置。安装NFS服务器并设置挂载路径：

   sudo apt-get install nfs-kernel-server
   sudo mkdir /data/nfs
   sudo vi /etc/exports  # 添加如下内容
   /data/nfs *(rw,sync,no_subtree_check)
   sudo exportfs -a
   sudo systemctl restart nfs-kernel-server

3. 创建一个PersistentVolume和PersistentVolumeClaim来定义NFS存储：

   apiVersion: v1
   kind: PersistentVolume
   metadata:
     name: nfs-pv
   spec:
     capacity:
       storage: 10Gi
     accessModes:
       - ReadWriteMany
     nfs:
       server: <NFS服务器IP地址>
       path: /data/nfs
   ---
   apiVersion: v1
   kind: PersistentVolumeClaim
   metadata:
     name: nfs-pvc
   spec:
     accessModes:
       - ReadWriteMany
     resources:
       requests:
         storage: 10Gi

4. 创建一个Pod来使用NFS存储：

   apiVersion: v1
   kind: Pod
   metadata:
     name: nfs-pod
   spec:
     containers:
       - name: nfs-container
         image: <容器镜像>
         volumeMounts:
           - name: nfs-volume
             mountPath: /data
     volumes:
       - name: nfs-volume
         persistentVolumeClaim:
           claimName: nfs-pvc
