### K8S集群文件共享实现原理 ###

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2E3NzIzMDQ0MTk_size_16_color_FFFFFF_t_70 1]

### 安装NFS相关组件 ###

# master节点上操作（master需安装nfs-utils和rpcbind，其他从节点只需安装nfs-utils）：
    yum install -y nfs-utils rpcbind

### 配置master ###

vim /etc/exports

### 配置从节点 ###

> 所有从节点都需执行这两步：  
> ①yum install -y nfs-utils  
> ②mount挂载

### 部署配置挂载点 ###

#### 删除deployment ####

#### 修改deployment脚本文件 ####

vim ./tomcat-deploy/tomcat-deploy.yml

![在这里插入图片描述][20200516165318775.png]

#### 重新创建部署 ####

kubectl create -f tomcat-deploy.yml

#### 验证配置 ####

> 查看从节点的pod容器中的Tomcat容器的webapps目录，文件是否同步了：
