docker配置文件

docker 的版本更新比较快, 而且现在几乎支持了包括 windows 和 mac 在内的所有系统平台(不知道啥时候可以在手机上运行 docker🐳 😆) 我在刚接触 docker 的时候使用的是1.9版本, 现在已经更新到了1.13.1版本, 变化很大, 相信有好多友友都找不到docker 的配置文件在哪里, 需要指定一些功能时, 一般会去 docker 的启动文件里配置. 本篇文章就介绍 docker 的默认配置文件在哪里, 怎么用

docker 1.12 版本之后, Linux 下(Ubuntu/RHEL/CentOS/Fedora/…)docker 的默认配置文件存放在 /etc/docker/daemon.js

如果你的 docker 是新装的, 那么这个文件默认不存在, 需要自己创建

根据官方文档介绍, daemon.js的配置模板如下
