Server discoverability - jellyfin with podman quadlet - shoebill - 2025-05-19

Hi,

I'm trying to run a jellyfin server as a podman quadlet on my PC. The server is up and running, and I can play stuff in the web client on my PC. However, I can't discover this service on my network so I can play it on my android TV.

Here's my configuration file:

Code:
[Unit]
Description=jellyfin

[Container]
Image=docker.io/jellyfin/jellyfin:latest
AutoUpdate=registrymedia
PublishPort=8096:8096/tcp
UserNS=keep-id
Volume=jellyfin-config:/config:Z
Volume=jellyfin-cache:/cache:Z
Volume=/var/mnt/docs/media:/media:Z
PublishPort=7359:7359/udp
PublishPort=1900:1900/udp

[Service]
# Inform systemd of additional exit status
SuccessExitStatus=0 143

[Install]
# Start by default on boot
WantedBy=default.target

I've tried a few things here based on googling.

Code:
PublishPort=7359:7359/udp
PublishPort=1900:1900/udp

I also tried this:

Code:
Network=host

But got the following error on startup:

Code:

RE: Server discoverability - jellyfin with podman quadlet - bitmap - 2025-05-19

Forgive me, I'm not super familiar with podman as I use docker compose. I see a few things here that I might be able to put you on the right track...

1. You can't map ports with something like host network mode with compose because that mode exposes the container to the host's network. That's the first error I believe.

2. That second error looks like you're trying to mount something that's not possible for one reason or another. Doesn't appear to be network related.

3. I was about to paste a compose file when I found this: https://jellyfin.org/docs/general/post-install/networking/#port-bindings

That explains what the ports are. So you would want 7359 published I believe, since that's client discovery. I'd look at fixing that second error and see what happens. You may also want to see if you can use the IP:PORT address for the server with your client and find/access it.
