[root@centos77 ~]# docker ps -a
CONTAINER ID        IMAGE                 COMMAND                  CREATED              STATUS                          PORTS                    NAMES
a88ea6f7c705        busybox:latest        "/bin/sh"                8 seconds ago        Up 7 seconds                                             blab1

Parameter description:
-i: standard input
-t: open a new terminal
-d: run in the background [generally must have this parameter], which is equivalent to open an additional terminal, to ensure that the container will not exit the program because the program is executed, thus Exit the container.
--Name: The function is to give the container a name to facilitate system operation and maintenance in the future.
