Unable to locate package msodbcsql on Python image

Question

This is the first time that I’m trying to use pyodbc to connect to an Azure SQL Database within a docker image. My Dockerfile looks like the below:

# the base image
FROM python:3

WORKDIR /usr/src/app

COPY requirements.txt ./
COPY music_trends.py ./

# install SQL Server drivers
RUN apt-get update
RUN apt-get update && ACCEPT_EULA=Y apt-get install -y msodbcsql unixodbc-dev

RUN pip install --no-cache-dir -r requirements.txt

COPY . .

CMD [ "python", "./music_trends.py" ]

Which throws the error message:

E: Unable to locate package msodbcsql
The command '/bin/sh -c apt-get update && ACCEPT_EULA=Y apt-get install -y msodbcsql unixodbc-dev' returned a non-zero code: 100

I have found resolutions for ubuntu:16.04 such as: https://github.com/Azure/azure-functions-docker/pull/45 and have also tried to run the msodbcsql.msi files from my Dockerfile.

Is there an equivalent fix for python:3?

python:3 is based on debian, so refer to microsoft doc:

You should install microsoft apt source, meanwhile change msodbcsql to msodbcsql17, example as next:

Dockerfile:

FROM python:3

RUN curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add - && 
    curl https://packages.microsoft.com/config/debian/9/prod.list > /etc/apt/sources.list.d/mssql-release.list && 
    apt-get update && 
    ACCEPT_EULA=Y apt-get install msodbcsql17 unixodbc-dev -y

UPDATE 2019-07-26:

I didn’t notice official python:3 image update from debian 9 to debian 10 early this month, see this

From microsoft guide above, it seems currently they just package every dependency ok for next:

#Debian 8
curl https://packages.microsoft.com/config/debian/8/prod.list > /etc/apt/sources.list.d/mssql-release.list

#Debian 9
curl https://packages.microsoft.com/config/debian/9/prod.list > /etc/apt/sources.list.d/mssql-release.list

Of course you can handle debian 10 dependency by yourself, such as libcrypto.so version issue etc, but I still suggest you just use python3 debian 9 version as microsoft did everything for you (PS: I think they will update in near future just because debian 10 release half month ago, I guess they need some time. BTW, https://packages.microsoft.com/config/debian/10/prod.list is there, but it does not have the package msodbcsql17 currently…)

So what I suggest easiest way for you is next, compared to the old Dockerfile, just change python:3 to python:3-stretch, and also install apt-transport-https which default not installed in debian 9, detail as follows:

Dockerfile:

FROM python:3-stretch

RUN apt-get update && 
    apt-get install -y apt-transport-https && 
    curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add - && 
    curl https://packages.microsoft.com/config/debian/9/prod.list > /etc/apt/sources.list.d/mssql-release.list && 
    apt-get update && 
    ACCEPT_EULA=Y apt-get install msodbcsql17 unixodbc-dev -y
