Hint: Some lines were ellipsized, use -l to show in full.

原因：
linux的内核中的SELinux不支持 overlay2 graph driver

解决办法：
修改配置文件
vi /etc/sysconfig/docker

    原文内容：
Modify these options if you want to change the way the docker daemon runs
OPTIONS=‘--selinux-enabled --log-driver=journald --signature-verification=false‘
