将文件从amazon s3桶复制到docker集装箱

Given that I have a s3 bucket called "mybucket" And I have a docker container called "myfileserver" And I have another docker container called "s3cli" with s3 cli commands And I am on "s3cli" when I try to copy files from "mybucket" to "myfileserver" Then I get confused how to do so? 

从s3cli容器运行命令时,将文件从mybucket复制到myfileserver的最佳方法是什么?

我想过使用容器之间共享的数据卷? 有什么更简单或更好?
