# Docker数据管理

**数据持久保存**

*  数据类型分为两种
  *  数据卷（Data Volume）：直接将宿主机目录挂载至容器指定的目录，此方法较常用；
  *  数据卷容器（Data Volume Container）：间接使用宿主机空间，先挂载一个专门的数据卷容器。

**数据卷**

*  使用场景
  *  数据库
  * 日志输出
  * 应用配置文件
  *  多容器目录或文件共享

```bash
#方式一
-v 宿主机目录:容器目录
 
#匿名卷
-v 容器路径
docker run -d -v /data/testdir:/data/nginx/htnl/ nginx
```

**数据卷容器**

```bash
--volumes-from
```
