Question

我正在尝试构建一个使用GDAL和必要的Python挂钩运行Alpine Linux的Docker容器：

FROM python:3.6-alpine

RUN apk update

RUN apk add py-gdal gdal

RUN pip install uwsgi

RUN mkdir /code
WORKDIR /code
COPY requirements.txt .

RUN pip install -r requirements.txt

COPY . .

CMD ["uwsgi", "--ini", "uwsgi.ini"]

如您所见，我正在运行apk update语句来更新存储库，然后运行apk add语句来安装软件包。这是我收到的输出：

/usr/bin/make -f /Users/some_guy/Workspace/tagging_tracker_backend/Makefile build up

这两个软件包均可在the Alpine Linux package website上找到。

我不熟悉Alpine Linux，但是习惯于在其他类型的Linux上安装软件包。这里是否需要传递另一个命令？

Answer 1

您链接到的gdal包位于边缘测试存储库中，而不是发行分支之一。要安装它，您必须专门指定该存储库。 gdal也依赖edge-main中的软件包，因此您也需要包括它。

apk add \
  --no-cache \
  --repository http://dl-cdn.alpinelinux.org/alpine/edge/testing \
  --repository http://dl-cdn.alpinelinux.org/alpine/edge/main \
  gdal

即使软件包回购网站上列出了Alpine Linux中缺少的软件包
