FileRun on Docker
You may want to set up a file server like FileRun for any number of reasons. The main reason, I would think, would be so you can have your own Google Drive alternative that is under your control instead of Google's. FileRun claims to be "Probably the best File Manager in the world with desktop Sync and File Sharing," but I think you'll have to be the judge of that for yourself.
