Question

我在Ubuntu 16.04上运行docker-ce。在构建我的自定义应用程序时，它失败了，因为它无法安装Flask，这是Python应用程序所必需的。

我支持我的组织代理，所以我也使用了内联代理。但它仍然失败了。

Dockerfile：

RUN pip install -r requirements.txt \ 
        --proxy https://10.70.52.146:3128 \
        --trusted-host pypi.python.org

requirements.txt：

Flask
Redis

输出：

Step 7/10 : RUN pip install -r requirements.txt     --proxy https://10.70.52.146:3128   --trusted-host pypi.python.org<br/>

The command '/bin/sh -c pip install -r requirements.txt     --proxy http://10.70.52.146:3128    --trusted-host pypi.python.org' returned a non-zero code: 1

此错误指的是什么？

将HTTP_PROXY和HTTPS_PROXY环境变量设置为构建参数可以解决您的问题。

Dockerfile：

FROM python:3.6
ADD requirements.txt requirements.txt
RUN pip install -r requirements.txt

构建命令：

docker build --build-arg HTTP_PROXY=https://10.70.52.146:3128 --build-arg HTTPS_PROXY=https://10.70.52.146:3128 .

在Dockerfile之外设置代理地址也是一种更好的做法，因为它允许您从组织网络外部重用此Dockerfile。
