A mapping of 3000:5000 means port 3000 on the host maps to port 5000 inside the container. A process running on the host machine must connect to port 3000 (the host-side port), and Docker forwards that traffic internally to port 5000 where the service is actually listening inside the container. Port 5000 (D) is only accessible inside the container, not from the host.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
