docker启动报错：Error starting daemon: SELinux is not supported with the overlay2 graph driver on this ke

环境：centos7

命令：systemctl start docker

          systemctl status docker -l

报错：Error starting daemon: SELinux is not supported with the overlay2 graph driver on this kernel. Either boot into a newer kernel or disable selinux in docker (--selinux-enabled=false)

解决方案：

意思是说：此linux的内核中的SELinux不支持 overlay2 graph driver ，解决方法有两个，要么启动一个新内核，要么就在docker里禁用selinux，--selinux-enabled=false

重新编辑docker配置文件：

vi /etc/sysconfig/docker

改为：

systemctl start docker
