Question

Tell me how to assign permissions to folders for the transmission application in docker? It's all about synology. It saves files only in the default folders and does not transfer to the desired one, since there are no rights to it. I use this assembly https://hub.docker.com/r/dperson/transmission/

Answer 1

Create a folder on the host from the desired user.
When starting, specify the user\group, throw /etc/groups /etc/passwd into the container (this is so that everything is correct with the rights)
and forward the folder (so that the container writes to the host).
Everything is practically the same as here - How to organize work with user access?
