Docker从12升级到17ce

先卸载

yum remove docker*
yum remove  container-selinux-1.12.-.el7.centos.x86_64

安装

sudo yum install -y yum-utils
yum-config-manager \
    --add-repo \
     https://download.docker.com/linux/centos/docker-ce.repo

必然失败，然后替换源再来

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
