Docker Container Permission Denied accessing rclone mount of Google Drive - UIDGID issues - Stack Overflow

I'm trying to mount a Google Drive folder as a volume in my Docker container using rclone mount. I've successfully mounted the drive on my Ubuntu 22.04 Docker host at /mnt/gdrive using the following command:

rclone mount gdrive:my-folder /mnt/gdrive --allow-other --vfs-cache-mode writes

My docker run command is:

docker run -d -v /mnt/gdrive:/app/data --name my-app my-image

However, when my application inside the container attempts to write to /app/data, I get "Permission denied" errors.

I've tried addressing this by using the --user flag in docker run:

docker run -d -v /mnt/gdrive:/app/data --user 1000:1000 --name my-app my-image

I determined the UID and GID (1000:1000) by running id myuser (where myuser is the user that runs rclone mount) on the host.

Despite this, the permission issues persist. I've also tried:

• chmod 777 /mnt/gdrive (as a test, which worked, but is obviously not a solution).
• Ensuring the user running the Docker daemon has access to /mnt/gdrive.

Here's the relevant output of ls -l /mnt/gdrive:

drwxr-xr-x 1 myuser myuser 0 Jan 1 00:00 .

Here's the output of docker version:

I acknowledge the content of this question but it wasn't helpful: How to fix Docker: Got permission denied issue

Note: some specific data and path names are omitted or modified in order to protect privacy of sensitive informations.

I suspect there's something I'm missing regarding user mappings between the host and container, especially with rclone. How can I correctly configure permissions so my container can write to the Google Drive mount?
