doc_cn/build/docker/build_docker_image.rst

-构建PaddlePaddle Docker Image
-===========================
-
-PaddlePaddle的Docker Image构建源码放置在 :code:`${源码根目录}/paddle/scripts/docker/`目录下。
-该Image基于ubuntu 14.04。该目录下有两个文件，Dockerfile和build.sh。其中:
-
-*  Dockerfile是docker image的主要描述文件。描述了Docker image的构建步骤、各种参数和维护
-   人员等等。
-*  build.sh是docker image的主要构建步骤。
-
-该image的构建在docker 1.12版本测试通过, 低于docker 1.12版本的情况下并没有测试。主要由于旧版本
-的docker可能缺乏 :code:`--build-arg` 参数，从而不能在运行编译命令的时候接受参数。
-
-同时，该构建脚本充分考虑了网络不稳定的情况，对于cuda的Toolkit有断点续传和传输速度过小重启下载的
-简单优化。
-
-使用脚本构建PaddlePaddle Docker Image
--------------------------------------------
-
-该脚本的使用方法是，进入该源码目录，执行 :code:`docker build .` 命令。可以使用
- :code:`--build-arg` 传入的配置参数包括:
-
-*  LOWEST\_DL\_SPEED\: 多线程下载过程中，最低线程的下载速度(默认单位是Bytes，可以传入10K, 
-   10M，或者10G这样的单位)。如果小于这个下载速度，那么这个下载线程将会关闭。所有的下载线程关闭时，
-   下载进程会重启。
-*  WITH\_GPU\: ON or OFF。是否开启GPU功能。注意，编译PaddlePaddle的GPU版本并不需要一定在具有GPU
-   的机器上进行。但是，运行PaddlePaddle的GPU版本一定要在具有CUDA的机器上运行。
-
-简单的使用样例为\:
-
-..  code-block:: bash
-
-    cd ${源码根目录}/paddle/scripts/docker/
-    docker build --build-arg LOWEST_DL_SPEED=50K\
-                 --build-arg WITH_GPU=ON \
-                 --tag  paddle_gpu:latest .
-
-即可在本地编译出PaddlePaddle的镜像。

+构建PaddlePaddle的Docker Image
+==============================
+PaddlePaddle的Docker Image构建源码放置在 ``${源码根目录}/paddle/scripts/docker/`` 目录下。该目录有三类文件：
+
+- Dockerfile：Docker Image的描述文件，包括构建步骤、各种参数和维护人员等。
+  
+  - 一共维护了12个Dockerfile，Dockerfile.m4是它们的模板。
+  - PaddlePaddle中所有的Image都基于ubuntu 14.04。
+
+- build.sh：Docker Image的构建脚本，使用方式见下一小节。
+- generate.sh：通过Dockerfile.m4模板生成不同的Dockerfile。
+
+使用脚本构建Docker Image
+------------------------
+
+进入源码目录，执行 ``docker build`` 命令，即可在本地编译出PaddlePaddle的镜像。简单的使用样例为
+
+..  code-block:: bash
+
+    cd ${源码根目录}/paddle/scripts/docker/
+    docker build --build-arg LOWEST_DL_SPEED=50K\
+                 --build-arg WITH_GPU=ON \
+                 --tag  paddle_gpu:latest .
+
+其中，``--build-arg`` 传入的配置参数包括:
+
+- LOWEST\_DL\_SPEED\: 在多线程下载过程中，设置下线线程的最低速度。
+
+  - 默认单位是Bytes，但可以传入10K、10M、或10G等这样的单位。
+  - 如果小于这个速度，那么这个线程将会关闭。当所有的线程都关闭了，那么下载进程将会重启。
+-  WITH\_GPU\: ON or OFF，是否开启GPU功能。注意，
+  - **编译** PaddlePaddle的GPU版本 **不一定** 要在具有GPU的机器上进行。
+  - **运行** PaddlePaddle的GPU版本 **一定** 要在具有GPU的机器上运行。
+
+注意：所有Image的构建在Docker 1.12版本测试通过, 低于1.12的版本并没有测试。原因是旧版本可能缺乏 ``--build-arg`` 参数，从而不能在运行编译命令的时候接受参数。
