Docker audio with pulseaudio
ドッカーでドッカーでPulseaudioを使って，ホストで音を出していてもコンテナで音を出せるようにする．
Create pulseaudio socket:
pacmd load-module module-native-protocol-unix socket=/tmp/pulseaudio.socket
Create /tmp/pulseaudio.client.conf for pulseaudio clients:
default-server = unix:/tmp/pulseaudio.socket
# Prevent a server running in the container
autospawn = no
daemon-binary = /bin/true
# Prevent the use of shared memory
enable-shm = false
Share socket and config file with docker and set environment variables PULSE_SERVER and PULSE_COOKIE. Container user must be same as on host:
docker run –rm \ –env PULSE_SERVER=unix:/tmp/pulseaudio.socket \ –env PULSE_COOKIE=/tmp/pulseaudio.cookie \ –volume /tmp/pulseaudio.socket:/tmp/pulseaudio.socket \ –volume /tmp/pulseaudio.client.conf:/etc/pulse/client.conf \ –user $(id -u):$(id -g) \ imagename
The cookie will be created by pulseaudio itself.
