We were using multiple container registries — across clouds and in-house (e.g., Nexus, GitLab Registry).
𝗧𝗵𝗲 𝗰𝗵𝗮𝗹𝗹𝗲𝗻𝗴𝗲: with so many registries scattered around, we had no unified view of whether each registry was actually up & reachable.
We lacked a simple dashboard telling us “Registry X is down.”
So I decided to build a lightweight UI application that addresses exactly this gap.
🔍 How it works: The app polls each registry endpoint at regular intervals, checks status (up/down) and logs results.
🖥️ We created a dashboard showing all registries, each with status indicator, last check time, and region.
🚨 When any registry goes down (and stays down), we trigger a proactive alert via MS Teams or email—before developers hit failures.
📊 We also track historical uptime so we can ask: which region fails most often? Which registry is most reliable?
💡 Why build it ourselves? Because we couldn’t find an off-the-shelf tool that monitored availability across multiple registries, platforms and clouds in the way we needed.
✅ The result: early detection, central visibility, fewer surprises, greater developer confidence.
📝 Key take-aways: choose a reliable health endpoint, set sensible intervals, avoid alert fatigue, centralize visibility.
🔧 Tech Stack: The entire solution is built using Python scripts, leveraging libraries like requests for HTTP checks and Flask for the dashboard interface.
