Docker 构建：运行 setup.py mariadb 安装失败
Docker build: Running setup.py install for mariadb fails
我正在为 python 代码 构建一个 docker 图像，它必须 连接远程 MariaDB 服务器.经过一些尝试和错误后，我能够在本地 运行 这个，但是为了使远程（虚拟）服务器上的安装更容易，我真的希望该解决方案也适用于 docker 图像。
一旦我使用旧的 alpine 版本 < 3.11，使用较低的版本就会导致兼容性问题：
MariaDB Connector/Python requires MariaDB Connector/C >= 3.1.5, found version 3.0.10
不同的 python 版本似乎也不起作用。
我的Dockerfile:
FROM python:3.6-alpine
RUN apk add --no-cache mariadb-dev build-base
RUN pip install mariadb
控制台输出：
> docker build . -t dockerpython

在安装 mariadb 之前，您需要安装一些依赖项。
MariaDB 版本 10.2 -- sudo apt-get install -y libmariadb-dev
MariaDB 版本 10.3 -- sudo apt-get install -y libmariadb-dev-compat
您可以使用 debian:slim 基本图像，而不是使用 alpine 或 python 基本图像。
中提交（并已修复）该错误
该修复程序将在 MariaDB Connector/Python 1.0.4 中提供（到本周末可能会通过 pypi.org 提供）。
作为解决方法，您可以从 github repository 下载最新版本并手动构建它，或者您可以尝试（我没有测试）
export CFLAGS=-D_GNU_SOURCE=1
