Modifying golang Docker Container using the running shell
问题
我正在使用Docker将我的Web服务部署到Google Compute Engine，并且我正在按照这里给出的说明进行操作：https://blog.golang.org/docker
我想在golang容器中安装ffmpeg，我的方法是通过以下命令获取对shell的访问权限：
docker run -t -i my-webservice /bin/bash
与ubuntu:14.04镜像相反，我无法访问bash shell。这是为什么呢？
我还找到了一个已经配置和安装了ffmpeg的镜像（https://registry.hub.docker.com/u/cellofellow/ffmpeg/）。是否可以从golang容器中访问该容器，还是我必须将ffmpeg安装到自己的docker镜像中？
英文:
I'm using Docker to deploy my web service to Google Compute Engine and I'm following the instructions given here: https://blog.golang.org/docker
I want to install ffmpeg in the golang container and my approach is to get access to the shell as
docker run -t -i my-webservice /bin/bash
In contrary to the ubuntu:14.04 image, I don't get access to the bash shell. How can that be?
I have also found an image, where the ffmpeg is already configured and installed (https://registry.hub.docker.com/u/cellofellow/ffmpeg/). Is it possible to get access to the container from the golang container or do I have to install ffmpeg into my own docker image?

更好的方法是通过在Dockerfile中添加RUN命令来将ffmpeg安装到你的Golang容器中，例如：
RUN apt-get update
RUN apt-get install -y ffmpeg
修改、Docker容器、运行shell这些词有点违背了Docker的含义。
英文:
A better approach would be to install ffmpeg to your golang container by adding a RUN to your Dockerfile, like
RUN apt-get update
RUN apt-get install -y ffmpeg
The words modifying, Docker Container, running shell, kind of contradicts the meaning of Docker.

安装ffmepeg并不简单，如果还需要安装其他编解码器，那就更麻烦了。这也是我想在编写Docker脚本之前先在shell中尝试一下的原因（可以从cellofellow/ffmpeg复制Docker脚本）。
这里有一个解决问题的答案：https://github.com/docker-library/golang/issues/27
英文:
Installing ffmepeg is not as simple if additional codecs need to be installed as well, being the reason that I would like to play around using the shell before writing the docker script (copying the Docker script from cellofellow/ffmpeg works).
An answer to the problems are described here: https://github.com/docker-library/golang/issues/27
