Updated Jellyfin in Synology Docker, apparently wiped cache/config

[MarkoM]

I have the same problem everytime i update docker image. I have to set up everything again.
Somehow when update happens it loses configuration and i have no idea how to connect it back.
Is there some way to safley update it so i dont lose everything everytime? I have tried to export settings but then it doesnt recognise them back so i stopped doing that...
Maybe my installation process is wrong (i do procedure from jellyfin documentation)?

You can follow my guide here: https://forum.jellyfin.org/t-guide-runni...er-compose

Your issue is that you're not mounting the config directory externally.
A container holds all its data inside itself. So if you delete it, all its data is gone.
That's why you need to mount the important data that you don't want deleted outside of it.

In order to update a program running with Docker containers, you can't update the container itself.
You always have to make a new container for the new updated program. You then would simply delete the old container.

Thank you for reply and help.
I followed guide and set up new server. I will see what happens when there is new update.
I guess i just start the project and login again?
