没啥事在写一篇，制作docker镜像，主要是把上一篇讯飞服务器的代码和环境打包到docker中。

之前还不知道怎么在docker中安装Python的第三方库，试过之后原来很简单，只要基于Python环境，在利用RUN命令pip install就行了。

最基本的制作，Dockerfile内容：

FROM python:3.5.6WORKDIR /serverCOPY ./dc_asr_client /server/dc_asr_client/COPY ./simplified_asr_server_rpc.py /server/RUN pip3 install websocketRUN pip3 install websocket-clientRUN pip3 install grpcio RUN pip3 install googleRUN pip3 install protobufEXPOSE 8015CMD python3 simplified_asr_server_rpc.py

逐行解释下dockerfile文件的内容：

基于Python3.5.6的镜像

工作目录：server

把本地的dc_asr_client 文件夹里的内容拷贝到镜像的/server/dc_asr_client/目录下，主要拷贝格式

把本地的服务器端文件simplified_asr_server_rpc.py 拷贝到镜像的/server目录下

安装websocket库

安装websocket-client库

安装grpcio

安装google

安装protobuf

暴露端口8015

最后运行主文件simplified_asr_server_rpc.py

docker镜像构建命令：

sudo docker build -t xunfei/dc_asr_rpc:1.2 . 

构建过程：
