docker安装、docker使用、docker UI
1，安装docker
a，切换到yum目录
[root@docker ~]# cd /etc/yum.repos.d/
b，yum repolist
[root@docker yum.repos.d]# yum repolist
网站链接：https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/
c，wget docker-ce：
[root@docker yum.repos.d]# wget https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo

[root@docker yum.repos.d]#
d，修改docker-ce：
[root@docker yum.repos.d]# vi docker-ce.repo
改为链接为清华镜像库的：https://mirrors.tuna.tsinghua.edu.cn/docker-ce
:%s@https://download.docker.com/@https://mirrors.tuna.tsinghua.edu.cn/docker-ce/@
e，查看是否有程序包：
"docker-ce.repo" 83L, 2880C written
[root@docker yum.repos.d]# yum repolist
