Hi all, first time poster here, because I was not able to find a solution to this issue on this forum, reddit or the rest of the internet… only people with apparently the same issue but the threads never got resolved. I am neither a TrueNAS pro nor a docker expert, so the solution might actually be …

I GOT IT RUNNING I eventually got miniDLNA running, the trick is to specify two additional environment variables PGID and PUID and set both to the user the app should run as (568 in my case). The note still says, that the app is running as unknown user and unknown group but the Permission denied …

Does it need to be DLNA or can you use something a little more natural like Emby, Kodi, Jellyfin or Plex? Once you step into the custom apps twilight zone, it’s hard to predict what will happen without good documentation. We can see you have an obvious permissions problem; the user/group recommended…

Thanks a lot for your answer I wanted to set this up specifically for my network connected Denon music player. According to its manual “This unit can play back music files and playlists (m3u, wpl) from DLNA compatible servers” This is why I went with this app. Currently I also don’t have any use…

I’ve seen some posts on here and reddit that had problems with media discovery when the app wasn’t using host networking. In the reddit post you linked the setup steps say he didn’t find a way to specify host networking. For reference see [image] Plex DLNA in same home network - no…

Thanks for your answer but I don’t think this is the issue. I was able to use host networking by just enabling the corresponding checkbox (see my settings). Must have been an update after the reddit post, that added the checkbox. Or maybe this checkbox does something else completely but since I was…

Did you add that user to the acls of the dataset you’ve mapped to the ap?

Yes, I did. Explicitly added the new user to the ACL and I also added the auxiliary groups built-in users and apps to this new user, which also have access to the dataset.

Resolved to using Plex now. It was surprisingly easy to set up and also enable DLNA although it feels like I am shooting with canons after sparrows (German proverb) as long as I am using Plex just for this purpose.

Hi captain! Thanks a lot, that’s the answer I was looking for, for several days now! How did you come up with the environment variables idea? Thanks

On the bottom of the docker page there is a link to an Ubuntu documentation page. There are many environment variables explained there for the app, but actually not these two, just one for the user (with a different variable name however?) On the background of everything I found out thus far I dug …

I eventually got miniDLNA up and running as a custom app.

Here’s my experiences & eventual success:

Like you, I needed miniDLNA for a “non-smart” networked device, in my case an Oppo 203.
