Pro Tips
Use 'docker system df' to see disk usage breakdown by images, containers, volumes, and build cache.
Run 'docker system prune -a --volumes' periodically to reclaim disk space from unused resources.
Check 'docker system events' for real-time Docker daemon events - useful for debugging.
Common Mistakes
'docker system prune -a' removes ALL unused images, not just dangling ones. Make sure you don't need them.
Adding '--volumes' to prune also removes named volumes. This can cause data loss.
