在多阶段Docker构建中复制ffmpeg容器 [英] Copy ffmpeg bins in multistage docker build

问题描述

我正在尝试通过多阶段docker build安装ffmpeg

I'm trying to install ffmpeg via a multistage docker build

这是包含ffmpeg二进制文件的ffmpeg映像

Here is the ffmpeg image that contains the ffmpeg binaries

FROM jrottenberg/ffmpeg

这是我需要运行Web服务器的pm2映像

Here is the pm2 image that I need to run my web server

FROM keymetrics/pm2:8-alpine

我将垃圾箱复制到当前映像中，可以看到ffmpeg，ffserver和ffprobe都存在于/ usr / local / bin中

I copy the bins into the current image, and I can see that ffmpeg, ffserver, and ffprobe all exist in /usr/local/bin.

COPY --from=0 /usr/local /usr/local

复制命令似乎成功，因为当我交互式运行容器时，这些文件存在。

The copy command appears to succeed, since those files exist when I run the container interactively.

$# which ffmpeg
/usr/local/bin/ffmpeg

但是，当我尝试运行垃圾箱时，它说未找到命令。

However, when I try running the bins, it says the command isn't found.

$# ffmpeg --version
/bin/sh: ffmpeg: not found

推荐答案

我遇到了类似的问题，最终使用支持构建静态 PIE二进制文件的高山gcc工具链构建了没有依赖性的我自己的二进制文件。原因是我不需要依赖项，无需构建，也支持ASLR。

I've had a similar issue and ended up building my own binaries with no dependencies using the alpine gcc toolchain that supports building "static" PIE binaries. The reason was that I wanted no dependencies, hardened build and also support ASLR.
