如何将GeoDjango添加到我的alpine dockerfile？

我想将GeoDjango（所需的部门：GDAL、GEOS、PROJ.4）添加到我的docker alpine图像中。我的Dockerfile已经有requirements.txt文件设置

我在PyPi上查找了GDAL，发现GDAL有四个依赖项：

“libgdal（3.0.1或更高版本）和头文件（gdal-devel） numpy（1.0.0或更高版本）和头文件（numpy-devel）（不是明确要求的，但许多示例和实用程序没有它就无法工作）

所以我想我需要加上：numpy，numpy-devel，libgdal和gdal-devel

我将这些依赖项添加到我的requirements.txt文件中，但我得到一条消息，numpy是继续使用GDAL所必需的

所以我直接将numpy添加到dockerfile中

Dockerfile

requirements.txt

 COPY ./requirements.txt /requirements.txt
 RUN apk add --update --no-cache postgresql-client jpeg-dev
 RUN apk add --update --no-cache --virtual .tmp-build-deps \
       gcc libc-dev linux-headers postgresql-dev musl-dev zlib-dev
 RUN pip install numpy==1.14.3 libgdal==3.0.1
 RUN pip install -r /requirements.txt
 RUN apk del .tmp-build-deps

 GDAL>=3.0.1,<3.1.0
