如何使用docker从后台代理运行pip3+git？

Question

使用pip3运行时如何设置git代理？在

遵循来自https://github.com/nouiz/Theano-Docker的说明

运行docker build -t theano_simple -f Dockerfile.0.8.X.jupyter.cuda.simple .时收到错误：

fatal: unable to connect to github.com:
github.com[0: 192.30.253.112]: errno=Connection timed out
github.com[1: 192.30.253.113]: errno=Connection timed out

向docker文件添加代理参数：

ENV HTTPS_PROXY=https://myproxy:1111 ENV HTTPS_PROXY=https://myproxy:1111 ENV https_proxy=https://myproxy:1111 ENV https_proxy=https://myproxy:1111

这是原始的docker文件：https://github.com/nouiz/Theano-Docker/blob/master/Dockerfile.0.8.X.jupyter.cuda.simple

使用代理命令修改docker文件：

     FROM nvidia/cuda:7.5-cudnn5-devel

        MAINTAINER FIX ME <fixme@example.com>

        RUN apt-get update && apt-get install -y --no-install-recommends \
                git \

                python3-dev \
                python3-numpy \
                python3-pip \
                python3-scipy && \
            rm -rf /var/lib/apt/lists/*

        RUN pip3 install \
                ipykernel \
                jupyter && \
            python3 -m ipykernel.kernelspec

        RUN pip3 install nose nose-parameterized

        ENV THEANO_VERSION 0.8.2

ENV HTTPS_PROXY=https://myproxy:1111
ENV HTTPS_PROXY=https://myproxy:1111
ENV https_proxy=https://myproxy:1111
ENV https_proxy=https://myproxy:1111

        RUN pip3 install git+git://github.com/theano/theano.git@rel-${THEANO_VERSION}

    RUN git config --global http.proxy myproxy:1111
    RUN git config --global https.proxy myproxy:1111

        COPY theanorc /root/.theanorc

        COPY start-notebook.sh /usr/local/bin/

        COPY jupyter_notebook_config_simple.py /root/.jupyter/jupyter_notebook_config.py

        COPY notebook /opt/notebook

        RUN apt-get update && apt-get install -y curl
        RUN mkdir /opt/data && cd /opt/data && curl http://www.iro.umontreal.ca/~lisa/deep/data/mnist/mnist_py3k.pkl.gz -o mnist.pkl.gz

我也尝试过将代理作为pip3 install:pip3 install --proxy myproxy:1111命令的一部分进行传递，但出现了相同的错误。在

Answer 1

fatal: unable to connect to github.com:
github.com[0: 192.30.253.112]: errno=Connection timed out
github.com[1: 192.30.253.113]: errno=Connection timed out

错误消息似乎是由RUN pip3 install引起的，因此add proxy for git不起作用。在

您可以尝试在pip install之前添加HTTPS_PROXYenv。在

Answer 2

你试过下列方法吗？在

pip3 install yourmodulename  trusted-host pypi.python.org

Answer 3

问题可能是您在公司代理/防火墙后面，并且传出连接在某个地方被阻止。一个简单的解决方案是将命令更改为https版本：

更改：

pip3 install git+git://github.com/theano/theano.git@rel-${THEANO_VERSION}

收件人：

pip3 install git+https://github.com/theano/theano.git@rel-${THEANO_VERSION}

或者：

您可以尝试以下步骤：https://help.github.com/articles/using-ssh-over-the-https-port/

这将通过https协议重定向所有git连接，这是大多数公司都允许的：）

祝你好运！在
