So I posted a draft awhile back and this now has many fixes including a proper r-clone boot up. I ran through this several times, so you should have very minimal issues.
If you have improvements for rclone, please let me know. The guide uses 100 percent docker containers and the paths are setup so everything that’s downloaded, bounces and hit rclone directly for upload! The YML for docker is written up for it. Plex utilizes PlexDrive for reading also incase.
