Alpine python映像上的MySQL加载共享库libmariadb时出错？

Question

我的Dockerfile：

FROM python:3.8-alpine

...

RUN apk add --no-cache --virtual .build-deps gcc libffi-dev openssl-dev musl-dev mariadb-dev \
    && pip install --no-cache-dir -r /code/requirements/production.txt \
    && apk del .build-deps gcc libffi-dev musl-dev openssl-dev mariadb-dev

...

要求：

django==2.2.9
mysqlclient==1.4.6
gunicorn==20.0.4
django-bootstrap3==12.0.3
django-fsm==2.7.0
djangorestframework==3.11.0

当我运行应用程序时，我从django获得以下信息：

ImportError: Error loading shared library libmariadb.so.3: No such file or directory (needed by /usr/local/lib/python3.8/site-packages/MySQLdb/_mysql.cpython-38-x86_64-linux-gnu.so)
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?

我已经安装了MySQL db adapter recommeneded，如何解决这个问题

Answer 1

我在docker-alpine github上找到了问题

解决方案是在安装依赖项之前添加mariadb-connector-c-dev包

RUN apk add  no-cache mariadb-connector-c-dev
