I'm trying to get a NodeJS server running pulseaudio inside Docker for the purposes of screen recording a pupeteer browser. I've left the extra bits off and just included a minimal example to get to where I'm stuck. Trying to run pulseaudio --system
gives Failed to open cookie file
. How do I create this file before hand or get it to create it on the fly.
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
Commands to run
docker build -t pulseaudio .
docker run -it --rm pulseaudio
Output

If you are using to root user in order to get it to work, you need to start the PulseAudio daemon.
Change the line to
pulseaudio -D --system
