在Centos 7上安装Docker-ce时遇到过这样的错误吗？
那么，解决它的最简单方法是安装container-selinux包。要执行此操作，请转至官方Centos Mirror，http：//mirror.centos.org/centos/7/extras/x86_64/Packages/并查找最新的软件包。正是container-selinux-2.68-1.el7.noarch.rpm在撰写本文时。获得后，复制其链接地址（url），前往要安装docker的服务器的终端并运行：
yum -y install yum -y install http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.68-1.el7.noarch.rpm
Loaded plugins: fastestmirror, langpacks
