docker啟動報錯：Error starting daemon: SELinux is not supported with the overlay2 graph driver on this ke__Linux

環境：centos7

命令：systemctl start docker

          systemctl status docker -l

報錯：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)

解決方案：

意思是說：此linux的核心中的SELinux不支援 overlay2 graph driver ，解決方案有兩個，要麼啟動一個新核心，要麼就在docker裡禁用selinux，--selinux-enabled=false

重新編輯docker設定檔：

vi /etc/sysconfig/docker

改為：

然後systemctl start docker 就好啦
