python - 在 ubuntu docker 镜像上连接时，SQL Server 的 ODBC 驱动程序 13 无法在 pyodbc 上打开 lib

Question

我被告知要单独问这个问题，但它与 this 有关在这里提问。

我在使用官方 Ubuntu (16.04) 创建的 docker 镜像上遇到了确切的问题。它适用于 isql，但不能通过 pyodbc 连接。以下是 odbc 跟踪:

这是我的 dockerfile:

FROM ubuntu:latest

RUN locale-gen en_US.UTF-8
ENV LANG en_US.UTF-8
ENV LANGUAGE en_US:en
ENV LC_ALL en_US.UTF-8

RUN apt-get update && \

感谢 Meet 和他在 Microsoft 的伙伴 Luis，我能够在 docker 容器中使用带有 pyodbc 的 conda 分发来连接 SQL Server。下面是他们为我配置的 dockerfile -

# mssql-python-pyodbc
# Python runtime with pyodbc to connect to SQL Server
FROM ubuntu:16.04

# apt-get and system utilities
RUN apt-get update && apt-get install -y \
    curl apt-utils apt-transport-https debconf-utils gcc build-essential g++-5\
    && rm -rf /var/lib/apt/lists/*

# adding custom MS repository
RUN curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add -
RUN curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list > /etc/apt/sources.list.d/mssql-release.list

# install SQL Server drivers
