I'm a Docker newbie - first time I've ever used it. I thought an easy way to get a first taste would be to use the Docker container option to install Jellyfin on a Raspberry Pi (Docker install instructions are here).
Except it isn't working. I installed the docker container on a Raspberry Pi by running docker pull jellyfin/jellyfin.
Then I ran
docker run -it -u {uid}:{gid} --name jellyfin --net=host --volume {HOMEDIR}/jellyfin-config:/config --volume {HOMEDIR}/jellyfin-cache:/cache --mount type=bind,source={HOMEDIR}/Music,target=/media jellyfin/jellyfin
(I have redacted my actual uid and gid and the home directory).
and several variations. When I do this, I get this output from docker container list -all:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 020748c27b2d jellyfin/jellyfin "/jellyfin/jellyfin" 3 seconds ago Exited (132) 2 seconds ago jellyfin
I tried to enter the container using --entrypoint=/bin/bash. When I get into the container and type jellyfin/jellyfin, I get a single word message Aborted.
Running docker logs for the container gets me no output at all. Running docker with the -it option, as above, also gets no output.
The user that I am on the system has write access to jellyfin-config, jellyfin-cache, and Music. When I run id inside the container, it reports the same user id and group id as my system user. When I run whoami, however, it says cannot find name for user xxx. When I run touch test inside /cache when running bash inside the container, I get an error that setting times is not permitted, but the file is written.
I'm not sure what is going on. I thought this might be a bug and have also posted to Jellyfin's issues, but no response there. Given that I am a Docker newbie, am I just using Docker wrong? How does one debug an error like this anyway?
