This article explores how to enable host systems to access Docker containers by name in development environments. Traditional methods like static IP configuration or external DNS servers pose maintenance complexity and security risks. We propose an event-driven solution using a bash script to dynamically update the host's /etc/hosts file for automatic container name resolution. Leveraging docker events to monitor container start and network disconnect events, combined with jq for parsing container information, this approach efficiently updates host files. Compared to polling mechanisms, it is more efficient; versus external dependencies, it is safer with fewer requirements. The article details script logic, system integration, and contrasts with alternatives like DNS Proxy Server, offering a lightweight, reliable practice for developers.
