Why Docker logs can eat a NAS

A home NAS is usually a single‑disk or a small RAID array.
When you run several containers—media servers, databases, CI runners—each one writes a JSON log file under /var/lib/docker/containers/<id>/<id>-json.log.
If you leave the default json-file driver untouched, those files grow indefinitely.
On a 1 TB NAS, a handful of containers can fill the drive in weeks, forcing you to delete data or upgrade hardware.
