In April 2025, Madko77 developed a DNS Listening Bind Mode for Pi-hole within the truenas/apps repository, introducing a new 'bind' mode that activates when host networking is enabled and an interface name is specified. This feature, implemented using YAML and configuration management skills, allows for more flexible and scalable DNS configurations in containerized environments. By integrating interface-based binding and host-networking support, Madko77 reduced manual setup time and improved deployment reproducibility for Pi-hole users. The work demonstrated a focused approach to DNS configuration challenges, with clear commit traceability and a targeted solution that addressed deployment flexibility without introducing bug fixes.
