Answer
Volumes persist after container deletion, accumulating unused data and consuming disk space.
Quick Answer
When you create a volume without naming it, Docker assigns a random ID. When you delete the container, the volume stays but becomes "orphaned" — no container references it, but it takes up disk space. Over time, hundreds of orphaned volumes accumulate. docker volume prune removes all that are unreferenced.
