General Docker troubleshooting:

docker info                             # Daemon info and config
docker system df                        # Disk usage
docker system prune                     # Clean up unused resources
docker inspect <container>              # Detailed container config
docker stats                            # Live resource usage
docker events                           # Real-time Docker events
