Question

这是我第一次使用Docker。我正在尝试安装jupyter并运行ipynb文件。我尝试了2张图片，但在两者上都遇到了相同的错误：
1）python：3.6.2-slim
2）jupyter /数据科学笔记本

Dockerfile：

#Use this python image
FROM python:3.6.2-slim
#Set metadata
LABEL maintainer="MyName"
#Set working directory to /app
WORKDIR /app
#Copy all files  in current directory to working directory (/app)
COPY . /app
#Install the required libraries
RUN pip --no-cache-dir install numpy pandas seaborn sklearn jupyter
#Make port 8888 available to the world outside this Container
EXPOSE 8888
#Run jupyter when container launches
CMD ["jupyter","notebook","--ip='*'","--port=8888","--no-browser","--allow-root"]

内部版本：

docker build -t helloworld_container .

运行：

docker run -p 9999:8888 helloworld_container

我收到以下错误：

Traceback (most recent call last):
  File "/opt/conda/lib/python3.6/site-packages/traitlets/traitlets.py", line 528, in get
    value = obj._trait_values[self.name]

我认为此问题的潜在解决方法是更新jupyter_notebook_config.py文件。所以我需要使用以下文件生成文件：

jupyter notebook --generate-config

我需要取消注释

#c.NotebookApp.ip = ‘*’

并将其设置为：

c.NotebookApp.ip = ‘0.0.0.0’

我知道如何在计算机上执行这些步骤，但是我不知道如何在映像上执行这些步骤。因此，我在机器上生成了配置文件，进行了更改，然后通过在dockerfile中添加以下行（并创建一个新容器）将其复制到容器中：

COPY jupyter_notebook_config.py /config/location/jupyter_notebook_config.py

这不能解决问题。

目前，我已移至已安装jupyter的其他映像（tensorflow \ tensorflow），但我想知道我在做什么错。

Answer 1

猜想这行，特别是"--ip='*'"是问题所在：

CMD ["jupyter","notebook","--ip='*'","--port=8888","--no-browser","--allow-root"]

我不确定docker文件如何转义，但是错误指出ip地址有误：

ValueError: '' does not appear to be an IPv4 or IPv6 address

请尝试此操作，以减少转义问题：

CMD["/bin/bash", "-lc", "jupyter notebook --ip=0.0.0.0 --port=8888 --no-browser --allow-root"]

Answer 2

您已经自己发现问题，因为您发现必须将*替换为0.0.0.0。但是，除了在配置中执行此操作外，您只需在命令中执行操作即可（无需使用bash）：

CMD ["jupyter", "notebook", "--ip=0.0.0.0", "--port=8888", "--no-browser", "--allow-root"]

此问题是通过notebook中的错误引入的，并在docker-stacks中进行了报告。

Answer 3

我想使用Docker运行Jupyter笔记本，而我也遇到了您报告的相同问题。幸运的是，我能够找到解决方案。

注意：我正在使用write_only=True图片。

步骤

从Docker Hub中拉取图像

docker pull continuumio/anaconda3

运行以下命令（该命令提供的文档图像不起作用并生成您报告的错误）

docker run -i -t -p 8888:8888 continuumio/anaconda3 /bin/bash -c "/opt/conda/bin/conda install jupyter -y --quiet && mkdir /opt/notebooks && /opt/conda/bin/jupyter notebook --notebook-dir=/opt/notebooks --ip='0.0.0.0' --port=8888 --no-browser --allow-root"

要完成这项工作，有两个关键的修改。 continuumio/anaconda3，使用--ip='0.0.0.0'代替--ip='*'。其次，添加--allow-root以查看浏览器中正在运行的笔记本。

在临时容器中添加卷

如果要创建一个临时容器，即暂时停止运行的容器，并且要创建一个卷，以便将在容器内创建的文件保存在主机中，请使用以下命令：

docker run --volume /path/in/your/host/jupyter_notebooks:/opt/notebooks --rm -it -p 8888:8888 continuumio/anaconda3 /bin/bash -c "/opt/conda/bin/conda install jupyter -y --quiet && /opt/conda/bin/jupyter notebook --notebook-dir=/opt/notebooks --ip='0.0.0.0' --port=8888 --no-browser --allow-root"
