What is the problem you are having with rclone?
I've set up a RClone docker container on my QNAP NAS and mounted 2 local folders to it.
One of it is an external hard disk connected via USB to the NAS.
Both mounted directories are accessible via command line in the docker instance.
Both mounted directories return their contents via the command rclone ls /location/of/local
What is your rclone version (output from rclone version)
1.51.0
Latest docker image
Which OS you are using and how many bits (eg Windows 7, 64 bit)
Linux QNAP NAS running docker via "container station"
Which cloud storage system are you using? (eg Google Drive)
None, only local folders
The command you were trying to run (eg rclone copy /tmp remote:tmp)
rclone sync -vv probeersellocal probeersel
or even
rclone copy -vv probeersellocal probeersel
probeersel = the, mounted in Docker, external hard drive connect to the NAS
probeersellocal = the, mounted in Docker, local folder on the NAS
A log from the command with the -vv flag (eg output from rclone -vv copy /tmp remote:tmp)
