node.js - Docker NodeJS 运行 pulseaudio --system 无法打开 cookie 文件

问题描述

我正在尝试让 NodeJS 服务器在 Docker 中运行 pulseaudio，以便对 pupeteer 浏览器进行屏幕录制。我已经把多余的部分去掉了，只包含了一个最小的例子来解决我遇到的问题。试图运行pulseaudio --system给出Failed to open cookie file. 我如何事先创建这个文件或让它动态创建它。

Dockerfile

FROM node:14

RUN apt-get update && apt-get install -y pulseaudio
RUN apt-get update && apt-get install -y pulseaudio-module-zeroconf
RUN apt-get update && apt-get install -y dbus-x11

RUN echo "load-module module-native-protocol-tcp auth-anonymous=1" >> /etc/pulse/default.pa
RUN echo "load-module module-zeroconf-publish" >> /etc/pulse/default.pa

COPY . .

CMD bash start_node.sh

start_node.sh

#!/bin/bash
service dbus restart
export $(dbus-launch)
pulseaudio --system

要运行的命令

docker build -t pulseaudio .
docker run -it --rm pulseaudio

输出

解决方案

如果您使用 root 用户来使其工作，您需要启动 PulseAudio 守护程序。

将行更改为 pulseaudio -D --system
