无法在Python映像上找到包msodbcsql

标签: sql-server azure docker odbc pyodbc

这是我第一次尝试使用pyodbc连接到docker映像中的Azure SQL数据库。我的Dockerfile如下所示:

# 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" ]

哪个抛出错误消息:

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

我找到了ubuntu:16.04的解析度,例如:https://github.com/Azure/azure-functions-docker/pull/45,并且还尝试从Dockerfile运行msodbcsql.msi文件。

是否存在python:3的等效修复程序?

答案 0 :(得分:1)

python:3基于debian,因此请参考microsoft doc

您应该安装Microsoft apt源,同时将msodbcsql更改为msodbcsql17,如下所示:

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

更新2019-07-26:

我没有注意到本月初从python:3debian 9的官方debian 10图片更新,请参阅this

从上面的Microsoft指南看来,当前他们只是将所有依赖项打包为下一个:

  

#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

当然,您可以自己处理debian 10依赖性,例如libcrypto.so版本问题等,但是我仍然建议您使用python3 debian 9 version,因为microsoft为您做了所有工作( PS:< / strong>我认为它们会在不久的将来更新,因为半个月前发布了debian 10,我想他们需要一些时间。顺便说一句,https://packages.microsoft.com/config/debian/10/prod.list在那里,但目前没有软件包msodbcsql17 ...)

因此,与旧的Dockerfile相比,我建议的最简单的方法是将python:3更改为python:3-stretch,然后安装apt-transport-https,默认情况下未安装在debian 9中,详细信息如下:

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
