Autostart of Jellyfin/Jellyfin container - Eisbergsalat - 2024-07-15

[*]Hey there,

[*]Before I start:
[*]This problem could actually be something with the published Jellyfin/Jellyfin container or with docker itself. I personally thought its most likely the first. Thats why I am here in this Forum.

[*]
  • The version of Jellyfin you are running:
  •      10.9.7

[*]
  • Your installation method and platform (e.g. Linux Docker, Debian repository, Windows installer, etc.)
         Jellyfin/Jellyfin Container in einer (priviliged) Proxmox VM

[*]
  • A brief description of the issue as your thread subject, using the description for additional important context only if required -> description
    (Im new here. Whats the difference between "Thread Subject" and "Description"?)

[*]
  • A full explanation of what is happening, versus what you expect to happen

[*]Expactaion:
[*]At 0:30 Proxmox shuts down every VM to reboot the whole Server. After reboot All VM restart. The Docker-VM starts and automatically starts all Containers including Jellyfin.
[*]
Reality:
[*]Proxmox works great at restarting!
[*]All VMs are restarting! (obviously this is the Jellyfin-Forum, I am getting to it :D)
[*]Inside of my Docker-VM almost all containers restart normally (Adguard, Dashy, Nextcloud, RustDesk, NginxProxyManager, Pufferpanel and Vaultwarden)
[*]Only the Jellyfin-container doesnt start.


[*]But If I reboot the whole Server manually everything works fine


[*]
  • What client(s) you are using and how the issue manifests
         Server is unrechable on any device, because the container isn't running.

[*]
  • Any other context you might think is relevant
"docker-compose.yml":

Code:
version: '3.5'
services:
  jellyfin:
    image: jellyfin/jellyfin
    container_name: jellyfin
    user: 1001:1001
    ports:
      - "8096:8096"
      - "8920:8920"
      - "7359:7359/udp"
      - "1900:1900/udp"
    volumes:
      - /Jellyfin/config:/config
      - /Jellyfin/cache:/cache
      - type: bind
        source: /mnt/Medien
        target: /media
    restart: always
    # Optional - alternative address used for autodiscovery
    environment:
      - JELLYFIN_PublishedServerUrl=https://#########.duckdns.org/
    # Optional - may be necessary for docker healthcheck to pass if running in host network mode
    #extra_hosts:
    #  - "host.docker.internal:host-gateway"

Due to the VM containing a few more containers as well as Adguard, I cant use host-mode

'####' - sind von mir unkenntlich gemacht. Ist ein privater Server, der nicht mehr als 5 Personen bewirtschaften kann.


Die VM ist aktuell (apt update && apt upgrade). Es handelt sich um einen headless Ubuntu (22.04.4 LTS) Server


Ich vermute mal, dass das nicht ausreicht, um den Fehler einzugrenzen. Ich weiß aber auch grad nicht was ich noch hinzufügen soll.
Was ich noch nicht gemacht hab. Und das werd ich gleich mal versuchen: Den Jellyfin auf z.B. 10.9.2 downgraden

RE: Autostart of Jellyfin/Jellyfin container - TheDreadPirate - 2024-07-15

The next time this happens run "sudo docker logs jellyfin" which should show any docker specific logs that aren't written to the Jellyfin log. The way you have things setup, docker should be starting the container.

RE: Autostart of Jellyfin/Jellyfin container - Eisbergsalat - 2024-07-17

With "sudo docker logs jellyfin" I get the same logs, that are in the OP.

The shutdown process is normal.
The container just wont start, if it is an automatic reboot.

One problem could be Adguard?
I run Adguard on the same VM as Jellyfin.
Does the newer version of Jellyfin need an active network connection to startup?
Adguard is my local DNS-Server

Today I downgraded the Jellyfinversion to 10.9.2
If that doesnt work I will try using more previous versions like 10.

Oh and sorry if I might take a few days to answer Ill try to answer as soon ass possible. I cant really take a lot of time for my Server administration at the moment.

RE: Autostart of Jellyfin/Jellyfin container - TheDreadPirate - 2024-07-17

Try to view the docker daemon logs with this command.

Code:
sudo journalctl -xu docker.service


RE: Autostart of Jellyfin/Jellyfin container - Eisbergsalat - 2024-08-15

Soooooo..
I..
- downgraded to version 9 - no difference (went back to :latest)
- changed the docker daemon.json experimental from true to false - no difference (Dont even know why I did That! Found that thanks to "journalctl -xu docker.service")
- fixed a DNS Error for the docker resolver - no difference obviously, if docker cant reach the Internet, the containers can still reach it. But the log shouldnt get used as garbage again (Also thanks to "journalctl -xu docker.service")
- Found out, that Nextcloud doesnt start right away because of Mounting-Problems. But thats soemthing NC tells me in the Windows-client every 5 damn minutes Grinning-face...  WiP but not relevant for this
- Get a lot of "ShouldRestart failed, container will not be restarted" container=... But that is before shutdown and the other listed containers startup as usally after the reboot.
- I also changed the chmod so that everyone can run the docker compose. (chmod a+x...)

I dont know why I cant copy the log from Putty at the moment... If I can, I will post it later.



Currently I am using a rather unwanted fix:
I created the "JellyfinStartup.sh" in the same folder as the docker compose file Grinning-face

Code:
docker compose down
sleep 60
docker compose up -d

and in crontab -e
Code:
45 2 * * * ....JellyfinStartup.Sh...




At the End of September I will be able to focus more on this, as the deadline of my Uni assignement ist at the beginning of Sep and the corresponding oral exam is at the end of Sep.



Edit:
Found out why I couldnt copy, it was an other programm with an invisible error message
I didnt try out the new .sh fix yet, so I will post the logs tomorrow.
Hopefully without as much clutter as I had till today Grinning-face

RE: Autostart of Jellyfin/Jellyfin container - Eisbergsalat - 2024-08-16

And now with the Log. I copied it from Putty directly with "Copy all to Clipboard". So some lines are cut off.
I fully copied those, that might point to the problem. If there are some lines that I should post completely please tell me.
(After I finished, I remebered that I could have just downloaded the whole file... now its to late... Well I only started about 2 years ago with the whole Linux thing)

Especially this line might be the clue to the perpetrator:
Code:

I looked into it and found out, that OMV (extra VM in Proxmox) is restarting at 2:30am and not fully back online until 3:00am.
In the time until 2:30 Adguard as well as my Router is also restarting interfering with my network.
It could be, that my Media folder is unreachable during container setup. So I will change the cron to 3:10 and I will also add "sleep 60" to the end (so that the script stays active during "docker compose up -d").
I think changing the docker compose file to "restart: never" is out of question. As I intend to restart the server sometimes during daytime.


And again: Tomorrow I will know more Upside-down-face
