最近在做的这个小项目做的是一个提供PaaS的后台服务，主要提供各种容器给用户，当前的后台做的比较简陋，主要通过Salt、Ansible这类工具手动发送命令到宿主机来创建容器，但好在基本实现了正常的自动化容器创建流程。 于是结合现有的后台框架先制作了Jupyter-notebook的Image，用于功能演示

制作Image

直接安装Jupyter Notebook

第一次尝试是直接找了个标准的Ubuntu镜像，根据Jupyter的官方教程安装Jupyter以及Ipython，由于在内网只能用内网的Python仓库，中间遇到了一些障碍，发现这条路走不通，遂放弃直接安装

通过安装Anaconda的方式来安装Jupyter notebook

在Jupyter的官网上就有建议通过安装Anaconda全家桶来安装jupyter，这个应该可以尝试一下吧，但是问题又来了，内网去哪里下载Anaconda的安装包呢，3ms一顿搜索之后，幸运的找到了一个Anaconda2的安装包，并且的确是可以用的

制作Jupyter notebook镜像

找到了可用的Anaconda安装包之后，后面的事情就好办了，可以编写Dockerfile来创建我们的镜像了 Dockerfile大致包括以下内容： + 使用内网镜像仓库的ubuntu作为OS + 更新apt源，并安装bzip2（安装anaconda的时候需要使用bzip进行解压） + 安装anaconda + 生成jupyter notebook的配置文件（生成后的配置文件路径为 ~/.jupyter/jupyter-notebook.py） + 修改jupyter notebook的配置文件（主要修改配置 允许root执行、允许外网接入、定义端口号以及token） + 容器启动命令，运行jupyter notebook server

Dockerfile内容如下：

FROM docker-hub.tools.huawei.com/tools/ubuntu:14.04.4 MAINTAINER "Kristian"

RUN apt-get update RUN apt-get install -y bzip2

#将Anaconda安装包拷贝至镜像中
ADD Anaconda2-5.0.1-Linux-x8664.sh / RUN chmod 755 /Anaconda2-5.0.1-Linux-x8664.sh

#执行安装脚本，安装Anaconda
RUN sh -c '/bin/echo -e "\nyes\n\nyes" | sh /Anaconda2-5.0.1-Linux-x86_64.sh'

#生成jupyter notebook的配置文件
WORKDIR /root/anaconda2/bin RUN sh -c './jupyter notebook --generate-config --allow-root'

#修改jupyter notebook的配置文件
#允许root用户执行
RUN sed -ie "s/#c.NotebookApp.allowroot = False/c.NotebookApp.allowroot = True/g" ~/.jupyter/jupyternotebookconfig.py

#允许外网接入，否则只能本机访问jupyter notebook页面
RUN sed -ie "s/#c.NotebookApp.ip = 'localhost'/c.NotebookApp.ip = '*'/g" ~/.jupyter/jupyternotebookconfig.py

#设置启动jupyter notebook的时候不一并打开浏览器，ubuntu上也没有浏览器给你打开啊 T_T
RUN sed -ie "s/#c.NotebookApp.openbrowser = True/c.NotebookApp.openbrowser = False/g" ~/.jupyter/jupyternotebookconfig.py

#设置jupyter notebook的访问端口，这里设置为9006与容器expose的端口号一致
RUN sed -ie "s/#c.NotebookApp.port = 8888/c.NotebookApp.port = 9006/g" ~/.jupyter/jupyternotebookconfig.py

#将token设置为空，这样在访问jupyter notebook时就不需要输入密码了
RUN sed -ie "s/#c.NotebookApp.token = '<generated>'/c.NotebookApp.token = ''/g" ~/.jupyter/jupyternotebookconfig.py

EXPOSE 9006

WORKDIR /root/anaconda2/bin 
RUN export PATH="$HOME/anaconda/bin:$PATH" 
CMD ["/bin/bash","-c","./jupyter notebook"] 

使用docker build命令成功制作镜像
