I am trying to build a docker image of python using the following dockerfile: I'm looking to have the smallest image so I use elyase/conda:2.7 image as a base:

 # 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

After running the command:

docker build -t repository.test .

I get this error:

I can't figure out how to install there packages that are necessary for my application

  • Please add verbosity option to opkg-install (--verbosity=4) and pip (--verbose) to have more information why it failed. Commented Jun 26, 2017 at 14:07
  • As you are overwriting /bin/python with your pyrun2.7, maybe opkg-install and pip packages can't run on it? Commented Jun 26, 2017 at 14:10
  • I want to make a small image so I'm using Pyrun. Commented Jun 26, 2017 at 14:11
  • it says: it is not compatible with this Python (from https://pypi.python.org/simple/pandas/); it is not compatible with this Python please check question update Commented Jun 26, 2017 at 14:13
  • Python is already in your base image, so changing it to another won't allow you to gain any space. Commented Jun 26, 2017 at 14:17

You are now using an old image elyase/conda:2.7 which references http://downloads.openwrt.org/snapshots/trunk/x86_64/generic/packages, but looks like it's now http://downloads.openwrt.org/snapshots/trunk/x86/64/packages.

You need to fix this URL in /etc/opkg.conf

Here is a Dockerfile for a relatively small image (105M) that should almost do the job:

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/*

You can adapt it to install any other lib you need, or install numpy with pip, so you won't have python and you will be able just use pyrun like you did before.

Unknown package 'awscli'.
Unknown package 'python-botocore'.

=> Pretty clear: 'awscli' and 'python-botocore' are not available openwrt packages, you should install them with pip I guess

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, urllib2 causing SSL: CERTIFICATE_VERIFY_FAILED: you need to install the opkg package ca-certificates.

But, then it will fails because it will try to build C-code so you have to install python headers and co.
