一. docker安装方法
1.部署环境
rhel7.6
docker 17.05
软件名:docker-ce-17.05.0.ce-1.el7.centos.x86_64.rpm
docker-ce-selinux-17.05.0.ce-1.el7.centos.noarch.rpm
docker软件下载地址

2.制作docker的yum源
1.先把软件包上传到服务器
2.配置yum源
[root@testwql ~]#mount /dev/sr0 /mnt ##这是我自己的yum源
mount: /dev/sr0 写保护，将以只读方式挂载
[root@testwql ~]# ls
anaconda-ks.cfg Music

docker-ce-selinux-17.05.0.ce-1.el7.centos.noarch.rpm Templates
Documents Videos
Downloads yum-ts.py
initial-setup-ks.cfg
[root@testwql ~]#mkdir docker ##制作docker的yum源
