Hi, I’m Yuzjing 👋
Welcome to my personal corner of the web. I’m a DevOps engineer with a constant curiosity for new technologies. I believe they are engines of change, offering elegant solutions to old problems and unlocking new possibilities, ultimately helping us make the most of our time.
This website is my space to document sparks of inspiration, lessons learned from challenges, and some occasional thoughts.
Beyond the code, I’m also exploring…
🌲 Into the Wild: On weekends, I love hiking in the nearby mountains. The fresh air is the perfect way to clear my mind and reboot.
🎵 A World of Music: My playlist is a melting pot, spanning from the melodies of Pop and the rhythms of House to the energy of Hardcore. For me, music is the perfect background for building mood and focus.
🚀 Exploring Fictional Worlds: Whether it’s the distant galaxies of sci-fi novels or the complex strategies of video games, I’m fascinated by exploring the grand worlds built from imagination.
My Projects#
Here’s a small tool I built:
GitHub Actions IP Firewall Auto-Updater#
- The Problem: Updating servers that use an IP allowlist (like Nftables) via GitHub Actions often failed because the runner IP addresses are dynamic.
- My Solution: I wrote a small tool in Go that automatically fetches the latest IP ranges used by GitHub Actions and updates the firewall rules. Combined with a Cron job, it creates a true “set it and forget it” solution.
- Find the code: You can check out the source code on GitHub.
