Hi Kru-x
I know this is an Old Repo and you haven't updated it in years, but I was playing around with it over the last few days and found a few things that would make it better:
Extra Parameters:
--user nobody
(By default the image creates a nobody attachment directory with a UID of 99, this won't let the container write files to the file system)
unRaid Share path: The image mount point is actually /data not /unraid changing the path will allow Wekan users to upload files and save them to the share drive. I know its working correctly when it created two directories under the share:
I would release another Wekan app, but your app has been in the repository for so long I wanted to help future users.
Cheers
