docker基础：Aufs存储驱动设定

ゝ一纸荒年。 2022-04-22 11:22 200阅读 0赞

本文用于记录ubuntu 17.10下docker 17.12.1-ce版本下overlay2的设定到aufs的方法。在Ubuntu 16.04以及更新的版本中，Linux内核引入了OverlayFS的支持，而且Docker CE也开始使用overlay2作为缺省的存储驱动，如果需要使用aufs，则需要进行手动配置。

什么是AUFS  
关于AUFS的简单说明，可以参看如下文章：

如何安装ubtuntu下的stable版的docker

设定daemon.json  
可以在docker的systemd的设定文件中添加–storage-driver, 也可以直接设定damon.json，而在实际使用的时候更推荐使用damon.json的方式, 添加如下文件，如果已经有设定文件，则将storage-driver一行加入即可
