Developed and delivered a Docker DNS resolution feature for the basecamp/omarchy repository, focusing on secure and reliable container networking. The solution enabled DNS queries from the 192.168 address range, but only when the UFW firewall was active, thereby maintaining a strong security posture and minimizing unnecessary exposure. This approach reduced DNS-related network issues for Dockerized services and streamlined internal troubleshooting. The work involved hands-on DevOps practices, firewall management, and network configuration, utilizing bash scripting to implement the changes. The feature improved the overall reliability of Docker networking while ensuring that security controls remained tightly integrated with operational workflows.
