牛皮，真可以下

[root@yinyujie ~]# vi /etc/docker/daemon.json
[root@yinyujie ~]#
[root@yinyujie ~]#
[root@yinyujie ~]# vi /etc/docker/daemon.json
[root@yinyujie ~]#
[root@yinyujie ~]#
[root@yinyujie ~]# systemctl daemon-reload
[root@yinyujie ~]#
[root@yinyujie ~]#
[root@yinyujie ~]#
[root@yinyujie ~]# systemctl restart docker
[root@yinyujie ~]#
[root@yinyujie ~]#
[root@yinyujie ~]# docker pull nginx

不过下的有点慢 要5分钟左右

docker pull nginx pull：下载的意思
docker run nginx run：启动镜像，跑起来了nginx
这时启动的应用nginx叫容器
