This image containerizes the Music Player Daemon to setup a centralized wifi controlled local music playing service. Compatible with ALSA but defaults to PulseAudio server running either on the host machine, or remotely somewhere in the network. Also includes yMPD for managing music via the browser, or via CLI using NcmpCPP.
Based on Alpine Linux from my alpine-s6 image with the s6 init system overlayed in it.
The image is tagged respectively for the following architectures,
- armhf
- armv7l
- aarch64
- x86_64 (retagged as the
latest
)
non-x86_64 builds have embedded binfmt_misc support and contain the qemu-user-static binary that allows for running it also inside an x86_64 environment that has it.
Pull the image for your architecture it's already available from Docker Hub.
# make pull
docker pull woahbase/alpine-mpd:x86_64
-
Config file mounted at
/etc/mpd.conf
edit or remount this with your own. Data stored at/var/lib/mpd
. -
Mount the music root dir at
/var/lib/mpd/music
. -
Mount playlists at
/var/lib/mpd/playlists
. -
Default configuration listens to ports
6600
and8000
, with the webui running on port64801
. -
This images already has a user
mpd
configured to drop privileges to the passedPUID
/PGID
which is ideal if its used to run in non-root mode. That way you only need to specify the values at runtime and pass the-u mpd
if need be. (runid
in your terminal to see your ownPUID
/PGID
values.) -
Default configuration forces the ALSA plugin to coerce to PulseAudio. Need to modify
/etc/asound.conf
as well as/etc/mpd.conf
to use ALSA device directly. -
The remote pulse server should allow
anonymous connections
if using without a cookie. ( Not really secure outside of a LAN)
If you want to run images for other architectures, you will need to have binfmt support configured for your machine. multiarch, has made it easy for us containing that into a docker container.
# make regbinfmt
docker run --rm --privileged multiarch/qemu-user-static:register --reset
Without the above, you can still run the image that is made for your architecture, e.g for an x86_64 machine..
Running make
starts the service.
If you're running the pulseaudio server on the host system, you can use the pulse server directly by mounting it inside the container
# make
docker run --rm -it \
--name docker_mpd --hostname mpd \
-c 256 -m 256m \
-e PGID=1000 -e PUID=1000 \
-e PULSE_SERVER=unix:/run/user/$(PUID)/pulse/native \
-v /run/user/$(PUID)/pulse:/run/user/$(PUID)/pulse \
-v /dev/shm:/dev/shm \
-v $(HOME)/.pulse-cookie:/home/mpd/.pulse-cookie
-p 6600:6600 \
-p 8000:8000 \
-p 64801:64801 \
-v music:/var/lib/mpd/music \
-v data:/var/lib/mpd \
woahbase/alpine-mpd:x86_64
or, use a remote pulseaudio standalone server running on a different device. ( checkout alpine-pulseaudio to run PulseAudio as a service )
# make
docker run --rm -it \
--name docker_mpd --hostname mpd \
-c 256 -m 256m \
-e PGID=1000 -e PUID=1000 \
-e PULSE_SERVER=localhost \
-p 6600:6600 \
-p 8000:8000 \
-p 64801:64801 \
-v music:/var/lib/mpd/music \
-v data:/var/lib/mpd \
woahbase/alpine-mpd:x86_64
Stop the container with a timeout, (defaults to 2 seconds)
# make stop
docker stop -t 2 docker_mpd
Removes the container, (always better to stop it first and -f
only when needed most)
# make rm
docker rm -f docker_mpd
Restart the container with
# make restart
docker restart docker_mpd
Get a shell inside a already running container,
# make debug
docker exec -it docker_mpd /bin/bash
set user or login as root,
# make rdebug
docker exec -u root -it docker_mpd /bin/bash
To check logs of a running container in real time
# make logs
docker logs -f docker_mpd
If you have the repository access, you can clone and build the image yourself for your own system, and can push after.
Before you clone the repo, you must have Git, GNU make, and Docker setup on the machine.
git clone https://github.com/woahbase/alpine-mpd
cd alpine-mpd
You can always skip installing make but you will have to type the whole docker commands then instead of using the sweet make targets.
You need to have binfmt_misc configured in your system to be able to build images for other architectures.
Otherwise to locally build the image for your system.
[ARCH
defaults to x86_64
, need to be explicit when building
for other architectures.]
# make ARCH=x86_64 build
# sets up binfmt if not x86_64
docker build --rm --compress --force-rm \
--no-cache=true --pull \
-f ./Dockerfile_x86_64 \
--build-arg DOCKERSRC=woahbase/alpine-s6:x86_64 \
--build-arg PGID=1000 \
--build-arg PUID=1000 \
-t woahbase/alpine-mpd:x86_64 \
.
To check if its working..
# make ARCH=x86_64 test
docker run --rm -it \
--name docker_mpd --hostname mpd \
-e PGID=1000 -e PUID=1000 \
--entrypoint sh \
woahbase/alpine-mpd:x86_64 \
-ec 'mpd --version; ncmpcpp --version; ympd --version'
And finally, if you have push access,
# make ARCH=x86_64 push
docker push woahbase/alpine-mpd:x86_64
