+# How to run PaddleServing in Docker
+
+## Requirements
+
+Docker (GPU version requires nvidia-docker to be installed on the GPU machine)
+
+## CPU
+
+### Get docker image
+
+You can get images in two ways:
+
+1. Pull image directly
+
+   ```bash
+   docker pull hub.baidubce.com/ctr/paddleserving:0.1.3
+   ```
+
+2. Building image based on dockerfile
+
+   Create a new folder and copy [Dockerfile](../Dockerfile) to this folder, and run the following command:
+
+   ```bash
+   docker build -t hub.baidubce.com/ctr/paddleserving:0.1.3 .
+   ```
+
+### Create container
+
+```bash
+docker run -p 9292:9292 --name test -dit hub.baidubce.com/ctr/paddleserving:0.1.3
+docker exec -it test bash
+```
+
+The `-p` option is to map the `9292` port of the container to the `9292` port of the host.
+
+### Install PaddleServing
+
+In order to make the image smaller, the PaddleServing package is not installed in the image. You can run the following command to install it
+
+```bash
+pip install paddle-serving-server
+```
+
+### Test example
+
+Get the trained Boston house price prediction model by the following command:
+
+```bash
+wget --no-check-certificate https://paddle-serving.bj.bcebos.com/uci_housing.tar.gz
+tar -xzf uci_housing.tar.gz
+```
+
+- Test HTTP service
+
+  Running on the Server side (inside the container):
+
+  ```bash
+  python -m paddle_serving_server.web_serve --model uci_housing_model --thread 10 --port 9292 --name uci &>std.log 2>err.log &
+  ```
+
+  Running on the Client side (inside or outside the container):
+
+  ```bash
+  curl -H "Content-Type:application/json" -X POST -d '{"x": [0.0137, -0.1136, 0.2553, -0.0692, 0.0582, -0.0727, -0.1583, -0.0584, 0.6283, 0.4919, 0.1856, 0.0795, -0.0332], "fetch":["price"]}' http://127.0.0.1:9292/uci/prediction
+  ```
+
+- Test RPC service
+
+  Running on the Server side (inside the container):
+
+  ```bash
+  python -m paddle_serving_server.serve --model uci_housing_model --thread 10 --port 9292 &>std.log 2>err.log &
+  ```
+
+  Running following Python code on the Client side (inside or outside the container, The `paddle-serving-client` package needs to be installed):
+
+  ```bash
+  from paddle_serving_client import Client
+  
+  client = Client()
+  client.load_client_config("uci_housing_client/serving_client_conf.prototxt")
+  client.connect(["127.0.0.1:9292"])
+  data = [0.0137, -0.1136, 0.2553, -0.0692, 0.0582, -0.0727,
+          -0.1583, -0.0584, 0.6283, 0.4919, 0.1856, 0.0795, -0.0332]
+  fetch_map = client.predict(feed={"x": data}, fetch=["price"])
+  print(fetch_map)
+  ```
+
+  
+
+## GPU
+
+The GPU version is basically the same as the CPU version, with only some differences in interface naming (GPU version requires nvidia-docker to be installed on the GPU machine).
+
+### Get docker image
+
+You can also get images in two ways:
+
+1. Pull image directly
+
+   ```bash
+   nvidia-docker pull hub.baidubce.com/ctr/paddleserving:0.1.3-gpu
+   ```
+
+2. Building image based on dockerfile
+
+   Create a new folder and copy [Dockerfile.gpu](../Dockerfile.gpu) to this folder, and run the following command:
+
+   ```bash
+   nvidia-docker build -t hub.baidubce.com/ctr/paddleserving:0.1.3-gpu .
+   ```
+
+### Create container
+
+```bash
+nvidia-docker run -p 9292:9292 --name test -dit hub.baidubce.com/ctr/paddleserving:0.1.3-gpu
+nvidia-docker exec -it test bash
+```
+
+The `-p` option is to map the `9292` port of the container to the `9292` port of the host.
+
+### Install PaddleServing
+
+In order to make the image smaller, the PaddleServing package is not installed in the image. You can run the following command to install it:
+
+```bash
+pip install paddle-serving-server-gpu
+```
+
+### Test example

+
+```bash
+wget --no-check-certificate https://paddle-serving.bj.bcebos.com/uci_housing.tar.gz
+tar -xzf uci_housing.tar.gz
+```
+
+- Test HTTP service
+
+  Running on the Server side (inside the container):
+
+  ```bash
+  python -m paddle_serving_server_gpu.web_serve --model uci_housing_model --thread 10 --port 9292 --name uci
+  ```
+
+  Running on the Client side (inside or outside the container):
+
+  ```bash
+  curl -H "Content-Type:application/json" -X POST -d '{"x": [0.0137, -0.1136, 0.2553, -0.0692, 0.0582, -0.0727, -0.1583, -0.0584, 0.6283, 0.4919, 0.1856, 0.0795, -0.0332], "fetch":["price"]}' http://127.0.0.1:9292/uci/prediction
+  ```
+
+- Test RPC service
+
+  Running on the Server side (inside the container):
+
+  ```bash
+  python -m paddle_serving_server_gpu.serve --model uci_housing_model --thread 10 --port 9292
+  ```
+
+  Running following Python code on the Client side (inside or outside the container, The `paddle-serving-client` package needs to be installed):
+
+  ```bash
+  from paddle_serving_client import Client
+  
+  client = Client()
+  client.load_client_config("uci_housing_client/serving_client_conf.prototxt")
+  client.connect(["127.0.0.1:9292"])
+  data = [0.0137, -0.1136, 0.2553, -0.0692, 0.0582, -0.0727,
+          -0.1583, -0.0584, 0.6283, 0.4919, 0.1856, 0.0795, -0.0332]
+  fetch_map = client.predict(feed={"x": data}, fetch=["price"])
+  print(fetch_map)

+# 如何在Docker中运行PaddleServing
+
+## 环境要求
+
+Docker（GPU版本需要在GPU机器上安装nvidia-docker）
+
+## CPU版本
+
+### 获取镜像
+
+可以通过两种方式获取镜像。
+
+1. 直接拉取镜像
+
+   ```bash
+   docker pull hub.baidubce.com/ctr/paddleserving:0.1.3
+   ```
+
+2. 基于Dockerfile构建镜像
+
+   建立新目录，复制[Dockerfile](../Dockerfile)内容到该目录下Dockerfile文件。执行
+
+   ```bash
+   docker build -t hub.baidubce.com/ctr/paddleserving:0.1.3 .
+   ```
+
+### 创建容器并进入
+
+```bash
+docker run -p 9292:9292 --name test -dit hub.baidubce.com/ctr/paddleserving:0.1.3
+docker exec -it test bash
+```
+
+`-p`选项是为了将容器的`9292`端口映射到宿主机的`9292`端口。
+
+### 安装PaddleServing
+
+为了减小镜像的体积，镜像中没有安装Serving包，要执行下面命令进行安装
+
+```bash
+pip install paddle-serving-server
+```
+
+### 测试example
+
+通过下面命令获取训练好的Boston房价预估模型：
+
+```bash
+wget --no-check-certificate https://paddle-serving.bj.bcebos.com/uci_housing.tar.gz
+tar -xzf uci_housing.tar.gz
+```
+
+- 测试HTTP服务
+
+  在Server端（容器内）运行：
+
+  ```bash
+  python -m paddle_serving_server.web_serve --model uci_housing_model --thread 10 --port 9292 --name uci &>std.log 2>err.log &
+  ```
+
+  在Client端（容器内或容器外）运行：
+
+  ```bash
+  curl -H "Content-Type:application/json" -X POST -d '{"x": [0.0137, -0.1136, 0.2553, -0.0692, 0.0582, -0.0727, -0.1583, -0.0584, 0.6283, 0.4919, 0.1856, 0.0795, -0.0332], "fetch":["price"]}' http://127.0.0.1:9292/uci/prediction
+  ```
+
+- 测试RPC服务
+
+  在Server端（容器内）运行：
+
+  ```bash
+  python -m paddle_serving_server.serve --model uci_housing_model --thread 10 --port 9292 &>std.log 2>err.log &
+  ```
+
+  在Client端（容器内或容器外，需要安装`paddle-serving-client`包）运行下面Python代码：
+
+  ```python
+  from paddle_serving_client import Client
+  
+  client = Client()
+  client.load_client_config("uci_housing_client/serving_client_conf.prototxt")
+  client.connect(["127.0.0.1:9292"])
+  data = [0.0137, -0.1136, 0.2553, -0.0692, 0.0582, -0.0727,
+          -0.1583, -0.0584, 0.6283, 0.4919, 0.1856, 0.0795, -0.0332]
+  fetch_map = client.predict(feed={"x": data}, fetch=["price"])
+  print(fetch_map)
+  ```
+
+## GPU版本
+
+GPU版本与CPU版本基本一致，只有部分接口命名的差别（GPU版本需要在GPU机器上安装nvidia-docker）。
+
+### 获取镜像
+
+可以通过两种方式获取镜像。
+
+1. 直接拉取镜像
+
+   ```bash
+   nvidia-docker pull hub.baidubce.com/ctr/paddleserving:0.1.3-gpu
+   ```
+

+   ```
+
+### 创建容器并进入
+
+```bash
+nvidia-docker run -p 9292:9292 --name test -dit hub.baidubce.com/ctr/paddleserving:0.1.3-gpu
+nvidia-docker exec -it test bash
+```
+
