Alpine Linux 中缺少包，即使它列在包回购网站上

Question

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

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，我运行既有 apk update 语句来更新存储库，又有 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

这两个包都可以在 the Alpine Linux package website.

找到

我不熟悉 Alpine Linux，但习惯在其他类型的 Linux 上安装软件包。这里是否还有其他命令需要传入？

Answer 1

您链接到的 gdal 包在边缘测试存储库中，而不是发布分支之一。要安装它，您必须专门指定该存储库。 gdal 也依赖于 edge-main 中的包，所以你也需要包括它。

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