Docker mapped volumes won't work with Emby

[DavidDK 2]

So I have docker installed on my Synology NAS. Before, I was using Plex native on Synology. So I'm new to Emby and new to docker. I have an Emby container with some mapped volumes to the media folders on my NAS. Screenshot of my docker setup included. Then I made 3 libraries in Emby pointing toward those mapped volumes (screenshot also included). Unfortunately, my libraries remain empty.

So setup looks like this:

• On my NAS I have a media folder with all my media files seperated into 3 different subfolders:
  • /volume1/media/movies
  • /volume1/media/music
  • /volume1/media/tvshows
• I have a docker container wit these folder mapped as follows:
  • /volume1/media/movies:/mnt/movies
  • /volume1/media/music:/mnt/music
  • /volume1/media/tvshows:/mnt/tvshows

I made sure the "emby" user on my NAS has permission to the /volume1/media folder as well as the /volume1/docker/emby folder. Though in de logging created while scanning library files I found an "UnauthorizedAccessException".

 

First question is, is this about folder permissions or is there a problem with how I mapped the docker volumes? And the second of course, how to fix this.

Hi, for Synology there's no need to use docker for Emby as it makes the configuration and permissions much harder.  I'd suggest downloading the current release right from out web site and installing it via package center.  Then set read/write permissions for the system internal emby user on any shares that Emby will access.

That should be all that's needed installing normally.

Hi, to answer the original question, it looks like emby server is being denied access to read the contents of the folders. Please let us know if this helps. Thanks.

This topic can be closed.

I made it work by giving the docker container full administrator rights on my NAS. That wasn't exactly the solution I was looking for though, so I decided to use the native Emby app for Synology instead of using Docker. Everything went fast 'n smooth after that.  

Thanks for the advise!

I was hoping you would do that.

Glad it all worked out for you.
