接下來創建一個資料夾叫mydata

執行

```
# docker run -it --rm -v /mydata:/data centos /bin/bash
```

切換到data資料夾底下

在資料夾底下創建任意文檔

```
# echo "hi" > a.txt
```

![](https://1005948644-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LZgzp55XQBZ7U2SrFtZ%2F-LaxhsmC4lyMeyB5RuyL%2F-LaxmK3mcv7MslicWuI7%2Fimage.png?alt=media\&token=4fa976f9-6062-411d-b0a7-241f9e8cd9f7)

開啟新的終端機切換到mydata資料夾下

確認資料夾下有沒有"a.txt"檔

你也可以在mydata資料夾下創建文件

確認data資料夾是否跟mydata同步
