如何以非root用户身份运行docker image？

问题描述

我是码头工人的新人。当我使用命令运行docker图像ubuntu映像时，

 中有一个名为 foo 的用户，您可以执行以下操作：
  sudo docker run -i -t -u foo ubuntu：14.04 / bin / bash 
  
 注意： 参数相当于说明。
 
I'm new to docker. When I run a docker images like ubuntu image by using the command,
sudo docker run -i -t ubuntu:14.04
By default, it is entering into the container as root like this.
I searched regarding this, but I couldn't get any of how to start a docker image as a non root user as I'm completely a starter for this topic.
It would be great if someone explains with an example of how to run a docker image as a non root user.
 解决方案 
the docker run command has the -u parameter to allow you to specify a different user. In your case, and assuming you have a user named foo in your docker image, you could run:
sudo docker run -i -t -u foo ubuntu:14.04 /bin/bash
NOTE: The -u parameter is the equivalent of the USER instruction for Dockerfile.
