问题描述
我正在为python代码构建 docker镜像，该镜像必须与远程MariaDB服务器连接。经过反复试验，我能够在本地运行此程序，但是为了使在远程（虚拟）服务器上的安装更加容易，我真的希望该解决方案也可以与docker映像一起使用。
当我使用旧的阿尔卑斯版本
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
Sending build context to Docker daemon 137.5MB

解决方法
在安装mariadb之前，您需要安装一些依赖项。
MariaDB版本10.2 -add_friendship
MariaDB版本10.3 -sudo apt-get install -y libmariadb-dev
您可以使用sudo apt-get install -y libmariadb-dev-compat基本图像，而不是使用高山或python基本图像。
我在MariaDB's ticket system中提交了（并且已经修复）该错误
该修复程序将在MariaDB Connector / Python 1.0.4中提供（可能在本周末通过pypi.org提供）。
作为一种解决方法，您可以从github repository下载最新版本并手动进行构建，也可以尝试（我没有对其进行测试）
export CFLAGS=-D_GNU_SOURCE=1
pip3 install mariadb
