We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

[sudo] password for docker: 
docker is not in the sudoers file.  This incident will be reported.

• 登录root，编辑文件，加用户docker到sudo文件

[root@iZuf6gl8wxyasxnj79v1g2Z docker]# visudo

• 增加用户

docker ALL=(ALL)    ALL
