Synology Docker install doesn't find media

[Sargon]

I have been running the SynoCommunity distribution of Jellyfin on my Synology NAS for a few years and have been happy with it, but recently the Android TV client was updated to a version that is no longer compatible with my server version.

In order to resolve that, I am attempting to configure Jellyfin through Docker instead.  I have completed the initial setup steps and mounted my media locations, but my libraries aren't detecting any media.  Here is what the mounted folders look like in Docker.



When I configure a media library, and click to add a folder, here is what I see initially.



I select the library that corresponds to the folder I want to map (in this case /video-movies) and then I see the following.



When I click on the ellipsis, then the folders change to the following.



This leads me to believe that something is not mapping properly to my media folders, because I can't see my media subfolders and it looks like it is redirecting back to the root directory.  Can anyone tell me where I may have went wrong and how I can fix this?

Thanks!

Here is one more piece of information from the log:

[2024-08-20 04:04:42.912 +00:00] [WRN] [8] MediaBrowser.Controller.Entities.BaseItem: Library folder "/video-movies" is inaccessible or empty, skipping
[2024-08-20 04:04:42.912 +00:00] [WRN] [8] MediaBrowser.Controller.Entities.BaseItem: Library folder "/video-other" is inaccessible or empty, skipping

So I think my library folders are somehow not pointing to the correct location, or possibly I have a permissions issue where the folder is not able to be read.

These are the users/groups that have permission to read my shared media folders. 



I thought 'SYSTEM' would take care of the permissions needed by Jellyfin, but perhaps not.  Note that sc-jellyfin and sc-media are leftover from the old SynoCommunity instance and are not relevant to the Docker install.  Are there other permissions I need to setup in order to properly share my media folder(s)?

Try reading over @Efficient_Good_5784 's guide on setting up Jellyfin on Synology NASes.

If his guide doesn't cover what you need, hopefully he will respond when he is available.

I was able to get the libraries working by granting read access on my media folders to all authenticated users. I would prefer to just grant access to the specific jellyfin user, but I'm not sure what user that would be on my Synology. Does anyone know?

@Sargon
Just provide the the containermanager user, read and write permissions on the parent folder of your media catalog.

The user you specify in Jellyfin will not reach outside of the container.

That will sort it out, without having to allow all authenticated users.
