不能构buildPython泊坞窗图像
我正在尝试使用下面的dockerfile来构build一个python的docker镜像：我正在寻找最小的镜像，所以我使用elyase / conda：2.7镜像作为基础：
# Pull base image. FROM elyase/conda:2.7 MAINTAINER me RUN opkg-install --verbosity=4 curl python-dateutil python-botocore && \ curl --no-verify-ssl https://bootstrap.pypa.io/get-pip.py && \ python get-pip.py && \ pip install --upgrade --user awscli && \ pip install boto3 chardet patool 运行该命令之后：
docker build -t repository.test .
我得到这个错误：

我不知道如何安装那些我的应用程序所需的软件包
您现在正在使用旧映像elyase / conda：2.7 ，其中引用了http://downloads.openwrt.org/snapshots/trunk/x86_64/generic/packages ，但看起来像是现在http://downloads.openwrt.org/snapshots / trunk / x86 / 64 / packages 。
你需要在/etc/opkg.conf修复这个URL
这是一个相对较小的图像（105M）的Dockerfile，应该几乎可以完成这项工作：
FROM alpine # Runtime packages RUN apk add --no-cache py-numpy sqlite-libs \ # Build packages && apk add --no-cache --virtual .build-deps \ py-pip \ musl-dev g++ python-dev py-numpy-dev \ ca-certificates \ # Runtime pip packages && pip install boto3 chardet patool \ # Pandas && pip install pandas \ # Cleaning && apk del .build-deps \ && rm -rf /root/.cache/ /var/cache/misc/*
你可以调整它来安装你需要的任何其他库，或者用pip安装numpy，所以你将不会有python，你就可以像以前一样使用pyrun 。
Unknown package 'awscli'. Unknown package 'python-botocore'.
=>很清楚：'awscli'和'python-botocore'不可用openwrt包，你应该用pip来安装它们
Download error on https://pypi.python.org/simple/: [SSL: CERTIFICATE_VERIFY_FAILED] unknown error (_ssl.c:661) -- Some packages may not be found!
=> Alpine 3.3，Python 2.7.11，导致SSL的urllib2：CERTIFICATE_VERIFY_FAILED ：您需要安装opkg包ca-certificates 。
但是，它会失败，因为它会尝试构buildC代码，所以你必须安装Python头和CO。
