## 制作Docker镜像
在一个功能齐全的Kubernetes机群里,通常我们会安装Ceph等分布式文件系统来存储训练数据。这样的话,一个分布式PaddlePaddle训练任务中的每个进程都可以从Ceph读取数据。在这个例子里,我们只演示一个单机作业,所以可以简化对环境的要求,把训练数据直接放在
PaddlePaddle的Docker image里。为此,我们需要制作一个包含训练数据的PaddlePaddle镜像。

## Build Docker Image
In distributed Kubernetes cluster, we will use Ceph or other shared storage system for storing training data so that all processes in the training job can retrieve data from Ceph. In this example, we will only demo training job on single machine. In order to simplify the requirement of the environment, we will directly put training data into PaddlePaddle's Docker Image, so we need to create a PaddlePaddle Docker image that already includes the training data.
PaddlePaddle's [Quick Start Tutorial](http://www.paddlepaddle.org/docs/develop/documentation/en/getstarted/index_en.html) introduces how to download and train data by using script from PaddlePaddle's source code.
And `paddledev/paddle:cpu-demo-latest` image has the PaddlePaddle source code and demo. (Caution: Default PaddlePaddle image `paddledev/paddle:cpu-latest` doesn't include the source code, PaddlePaddle's different versions of image can be referred here: [Docker installation guide](http://www.paddlepaddle.org/doc/build/docker_install.html)), so we run this container and download the training data, and then commit the whole container to be a new Docker image.
