Question

我正在使用https://hub.docker.com/r/tiangolo/meinheld-gunicorn-flask/来托管Flask API。

要进行部署，我使用在Azure Web应用程序服务上托管的Docker镜像容器。我正在尝试将我的烧瓶应用程序连接到Azure SQL服务器。但是我无法安装正确的odbc驱动程序和pyodbc。

我的docker文件：

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
RUN apt-get update && ACCEPT_EULA=Y apt-get -y install msodbcsql17
RUN apt-get -y install unixodbc unixodbc-dev

# install necessary locales
RUN apt-get update && apt-get install -y locales \
    && echo "en_US.UTF-8 UTF-8" > /etc/locale.gen \
    && locale-gen


FROM tiangolo/meinheld-gunicorn:python3.7
ENV LISTEN_PORT=80
EXPOSE 80

COPY /app /app

# Uncomment to install additional requirements from a requirements.txt file
COPY requirements.txt /


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

得到错误：

gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -fPIC -DPYODBC_VERSION=4.0.25 -I/usr/local/include/python3.7m -c src/buffer.cpp -o build/temp.linux-x86_64-3.7/src/buffer.o -Wno-write-strings

2019-01-28T23:58:42.5007377Z     error: command 'gcc' failed with exit status 1

我认为是因为unixodbc未正确安装？

Answer 1

第二行if "owl" in x可能意味着以后的操作是对没有编译pyodbc所需的那些库的映像执行的。
