本人在初学docker的时候，感觉对于docker的配置文件有点搞不定，一会是/etc/sysconfig/docker，一会是/etc/docker/daemon.json，一会是/etc/systemd/system/docker.service.d目录下，更有甚者是/usr/lib/systemd/system/docker.service。
比如配置一个INSECURE-REGISTRY，就可以在/etc/sysconfig/docker文件里添加，也可以在/etc/docker/daemon.json文件里添加。特别的，这两个文件里的格式还不一样！！
这些配置文件到底是什么关系呢？是怎么被docker加载生效的呢？下文简单讲述他们之间的关系及docker的一些配置文件规划。
可以看到，加载的其实是/usr/lib/systemd/system/docker.service这个文件。
有了这个文件，我们一些常规的配置，都可以统一在这个文件里进行设置了，如下是/etc/docker/daemon.json的所有配置项：
