Hi,
I didn't find any information of how to run CDplayer plugin on official
docker for LMS. Therefore I figured this out myself. Here is what worked
for me if anyone is interested (e.g. future me ;) ). This is for docker
run on Linux host. For other OSes some parts may be different.
First check out the permissions of CDROM device:
Code:
--------------------
> /usr/bin/ls -l /dev/cdrom
lrwxrwxrwx 1 root root 3 12-14 10:31 /dev/cdrom -> sr0
> /usr/bin/ls -l /dev/sr0
brw-rw---- 1 root optical 11, 0 12-14 10:31 /dev/sr0
--------------------
So anyone in
Code:
--------------------
optical
--------------------
group can read CD. To setup docker we need numerical ID of the group
rather than name, so
Code:
--------------------
> getent group optical
optical:x:990:
--------------------
We see It is 990.
Let's assume we want to run LMS as -lms- user, which is already present
on host.
Add -lms- user to -optical- group:
Code:
--------------------
> usermod -aG optical lms
--------------------
Now put the following script in -config- folder of LMS, named
-custom-init.sh-:
Code:
--------------------
cd_group_id=990
cd_group_name=optical
lms_user=squeezeboxserver
# Prepare for CDplayer
if ! command -v cdda2wav >/dev/null 2>&1; then
echo 'Installing icedax (for cdda2wav)'
apt-get update -qq
apt-get install --no-install-recommends -qy icedax
fi
if ! getent group $cd_group_id >/dev/null 2>&1; then
echo "Adding $cd_group_name($cd_group_id) group"
groupadd -g $cd_group_id $cd_group_name
fi
if ! getent group $cd_group_id | grep -q "\b$lms_user\b"; then
echo "Adding $lms_user user to $cd_group_name group"
usermod -aG $cd_group_id $lms_user
fi
--------------------
Change
Code:
--------------------
cd_group_id
--------------------
to your group ID.
Code:
--------------------
cd_group_name
--------------------
must not clash with groups already existing in container but otherwise
is irrelevant.
Code:
--------------------
lms_user
--------------------
is the name of user that runs LMS inside container, so must be as it
is.
The script is run *inside container* after container start by sh. It
will install -cdda2wav- and setup permissions so the user that runs LMS
can access host's CDROM device.
The last step is to update docker-compose.yml to add device mapping and
set the user inside the container to have the same ID as our host's
-lms- user:
Code:
--------------------
> id lms
uid=972(lms) gid=972(lms) groups=972(lms),990(optical)
--------------------
UID is 972.
So add mapping and set user in relevant parts of docker-compose.yml:
Code:
--------------------
services:
lms:
device:
- /dev/cdrom:/dev/cdrom:r
environment:
- PUID=972
--------------------
