Node.js Docker NodeJS运行pulseaudio--系统无法打开cookie文件

我试图让NodeJS服务器在Docker内部运行pulseaudio，以便在屏幕上录制Pupeter浏览器。我省略了多余的部分，只提供了一个最简单的例子来说明我的问题。尝试运行

pulseaudio--system

时，无法打开cookie文件

。我如何在手之前创建这个文件，或者让它动态创建它

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

启动节点。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

如果您正在使用根用户以使其工作，则需要启动PulseAudio守护进程

换行
pulseaudio-D——系统
