如何在dockerpython镜像中安装GDAL库？

Question

我在django项目中使用python3.7-slim-buster docker图像。现在我想使用django的地理特征。但看来我必须安装GDAL。所以，我运行apt-get-install-gdal并引发异常“E:Unable-locate package-gdal-bin”。 这是我的docker文件：

FROM python:3.7-slim-buster

ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1
# DB vars
ENV DB_USER_NAME ${DB_USER_NAME}
ENV DB_NAME ${DB_NAME}
ENV DB_HOST ${DB_HOST}
ENV DB_PORT ${DB_PORT}
ENV DB_PASSWORD ${DB_PASSWORD}

ENV DJANGO_SECRET_KEY ${DJANGO_SECRET_KEY}

RUN apt-get install -y gdal-bin python-gdal python3-gdal

RUN ["adduser", "${USER_NAME}", "--disabled-password", "--ingroup", "www-data", "--quiet"]

USER ${USER_NAME}

ADD ${PROJECT_NAME}/ /home/${USER_NAME}/${PROJECT_NAME}
WORKDIR /home/${USER_NAME}/${PROJECT_NAME}

ENV PATH="/home/${USER_NAME}/.local/bin:\${PATH}:/usr/local/python3/bin"

RUN pip install --user -r requirements.txt

CMD python manage.py runserver 0.0.0.0:9000
#CMD gunicorn ${PROJECT_NAME}.wsgi:application --bind 0.0.0.0:8000
EXPOSE 8000

Answer 1

您需要执行以下操作：

RUN apt-get update
RUN apt-get install -y software-properties-common && apt-get update
RUN apt-get install -y python3.7-dev
RUN  add-apt-repository ppa:ubuntugis/ppa &&  apt-get update
RUN apt-get install -y gdal-bin libgdal-dev
ARG CPLUS_INCLUDE_PATH=/usr/include/gdal
ARG C_INCLUDE_PATH=/usr/include/gdal
RUN pip install GDAL

Answer 2

这是因为您的图像没有包含gdal-bin包的存储库。所以您必须添加存储库（您可以看到指南here）并安装它：

RUN add-apt-repository ppa:ubuntugis/ppa && apt-get update && apt-get install -y gdal-bin python-gdal python3-gdal
