docker - 在 dockerfile 中安装包

Question

下面是带有 ffmpeg 安装详细信息的 dockerfile。

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base

RUN sed -i 's/deb.debian.org/mirrors.ustc.edu.cn/g' /etc/apt/sources.list \
    && apt-get update \
    && apt-get install -y ffmpeg \
    && apt-get clean && apt-get autoclean && apt-get autoremove \
    && rm -rf /var/lib/apt/lists/*

RUN apt-get update && apt-get install -y libgdiplus libc6-dev && ln -s /usr/lib/libgdiplus.so /usr/lib/gdiplus.dll
WORKDIR /app
EXPOSE 80
EXPOSE 443
...

如何安装不同的 ffmpeg 包，更具体地说 alfg/ffmpeg
以这种方式保持 dockerfile 的其余部分完好无损并具有相同的安装路径 /usr/bin/ffmpeg .

这是我的 Dockerfile

不确定这会改变 ffmpe 二进制文件的路径。使用旧的 Dockerfile(本例中的第一个)它工作得很好(在查找 ffmpeg 二进制文件时)。它是从这样的代码中引用的

string ffmpegPath = "/usr/bin/ffmpeg";
string ffprobePath = "/usr/bin/ffprobe";

现在有了新的 dockerfile 我得到了

System.ComponentModel.Win32Exception: 'An error occurred trying tostart process '/usr/bin/ffmpeg' with working directory '/app'. No suchfile or directoryObviously I need to change path to match the new installation path, tried with /opt/ffmpeg but that doesn't work.

你可以在这里找到他们构建的 Dockerfile https://github.com/alfg/docker-ffmpeg/blob/master/Dockerfile .
也许您可以将他们的 dockerfile 的一部分复制到您的文件中。
这是我的尝试。我将您的 aspnet 镜像切换到 alpine，因为 ffmpeg dockerfile 是 alpine 并且更改包管理器似乎是一项艰巨的任务。
