解决方案：

1.修改之前创建文件夹权限

[root@localhost srv]# ll
总用量 0
drwxr-xr-x 2 root    root 20 4月   1 14:12 conf
drwxr-xr-x 2 polkitd root  6 4月   1 14:39 data
drwxr-xr-x 2 root    root  6 4月   1 11:13 logs
[root@localhost srv]# chmod 777 logs
[root@localhost srv]# ll
总用量 0
drwxr-xr-x 2 root    root 20 4月   1 14:12 conf
drwxr-xr-x 2 polkitd root  6 4月   1 14:39 data
drwxrwxrwx 2 root    root  6 4月   1 11:13 logs
[root@localhost srv]# chmod 777 conf
[root@localhost srv]# chmod 777 data
[root@localhost srv]# ll
总用量 0
drwxrwxrwx 2 root    root 20 4月   1 14:12 conf
drwxrwxrwx 2 polkitd root  6 4月   1 14:39 data
drwxrwxrwx 2 root    root  6 4月   1 11:13 logs

2.重启容器

[root@localhost srv]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                     PORTS               NAMES

[root@localhost srv]# docker start 848a2581da80
