Docker build ：不可滿足的約束

Question

我正在嘗試設置可以運行 CVTree 3.0 的 docker 映像（ https://github.com/ghzuo/CVTree ）。 但是，我收到了這個錯誤：

    Sending build context to Docker daemon  206.1MB

RUN echo "http://dl-4.alpinelinux.org/alpine/edge/testing" >> /etc/apk/repositories
RUN apk --update add --no-cache g++ make cmake zlib-dev hdf5-dev hdf5-static

## Build cvtree
WORKDIR /root
COPY ./src /root/cvtree/src
COPY ./CMakeLists.txt /root/cvtree/
RUN mkdir cvtree/build/ && cd cvtree/build/ && cmake .. && make 

## Stage for run cvtree 
FROM alpine AS run
COPY --from=dev /root/cvtree/build/bin/* /usr/local/bin/
RUN apk --update add --no-cache libgomp libstdc++

## for workplace
WORKDIR /root/data

我怎樣才能解決我的問題？ 任何幫助將不勝感激。

Answer 1

可用軟件包列表中缺少軟件包hdf5-Dev和hdf5-static ，因此構建失敗。

嘗試使用 alpine edge 社區 docker 圖像：

## for develop environment
RUN apk --update add --no-cache g++ make cmake zlib-dev
RUN apk add hdf5-dev hdf5-static --repository=http://dl-cdn.alpinelinux.org/alpine/edge/community

Answer 2

我運行了以下，它工作正常

RUN apk add --no-cache --repository http://dl-cdn.alpinelinux.org/alpine/edge/community hdf5-dev
