Installing postgresql-dev for Postgres 9.6.x in a Dockerfile?

I have been fruitlessly searching the internet for 2 days now looking for a way to install postgresql-dev for 9.6 due to an extremely outdated dep I'm trying to run. Unfortunately, running the following Dockerfile commands:

FROM python:2.7-alpine
ENV PYTHONUNBUFFERED 1
RUN mkdir /app/
RUN mkdir ./app/logs/
RUN mkdir ./app/xxx/
WORKDIR /app/xxx/
ADD requirements.txt /app/xxx/
ADD ./ /app/xxx/
RUN apk --update add python py-pip openssl postgresql-dev ca-certificates py-openssl libffi-dev musl-dev openssl-dev wget build-base gcc python-dev py-pip jpeg-dev zlib-dev libx
ml2 libxslt-dev                                                                                                                                                                 
ENV LIBRARY_PATH=/lib:/usr/lib
RUN pip install --upgrade pip setuptools
RUN pip install psycopg2==2.4.5

Gives me the following error:

Collecting psycopg2==2.4.5
  Downloading https://files.pythonhosted.org/packages/36/77/894a5dd9f3f55cfc85682d3e6473ee5103d8d418b95baf4019fad3ffa026/psycopg2-2.4.5.tar.gz (719kB)
    Complete output from command python setup.py egg_info:

    Error: could not determine PostgreSQL version from '11.2'

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-UcoQQZ/psycopg2/

Which I understand means that I'm installing PostgreSQL 11.2 from postgresql-dev when I need 9.6. I cannot seem to find this apk anywhere, and running postgresql-dev=9.6.5 or its equivalents does not appear to work either.

Is there any way to get this version of postgresql-dev from python2.7 alpine (or any other docker)? I saw that there are postgres docker containers but I'm new to docker and couldn't get them running either (psycopg2 was completely unable to find their installations)

The closest version to postgresql-dev 9.6.5 in Alpine repositories is 9.6.10-r0, used in Alpine 3.5: https://pkgs.alpinelinux.org/package/v3.5/main/x86_64/postgresql-dev

Regardless of your Alpine version, you could instruct apk to pick this exact version from the V3.5 apk repository:

apk add postgresql-dev=9.6.10-r0 --repository=http://dl-cdn.alpinelinux.org/alpine/v3.5/main

This works for me: 

# Python 3.6 on Alpine linux, a snall secure flavor of linux
FROM python:3.6-alpine

# Add community repositories to install dependencies
RUN echo "http://dl-8.alpinelinux.org/alpine/edge/community" >> /etc/apk/repositories

# These dependencies are required for matplotlib and numpy
RUN apk --no-cache --update-cache add gcc freetype-dev libpng-dev musl-dev linux-headers g++ gfortran python3-dev

# This symlink fixes an error in numpy compilation
RUN ln -s /usr/include/locale.h /usr/include/xlocale.h

# Postgres libs and dependencies, plus python-ldap depdency
RUN apk --no-cache --update-cache add postgresql-libs postgresql-dev libffi-dev openldap-dev unixodbc-dev git 

COPY requirements.txt /app_name/requirements.txt

RUN pip3 install --upgrade pip
RUN pip3 intall --upgrade setuptools

RUN pip3 install -r /app_name/requirements.txt # includes psycopg2==2.7.3.1

Perhaps you can translate that to work with python27?

(btw Python 2.7 is going away soon, FYI)
