What is the problem you are having with rclone?
I use the command "mount" ,get no error, but there is no folder mount on local folder.
Local folder's authority is set to everyone can rw.
(/volume1/docker/rclone/config and /volume2/FHM/GD)
I've try two image which are rclone/rclone and mumiehub/rclone-mount, and get the same result.
