Uyuni Event-Driven Automation via MQTT and Node-RED

Uyuni is a powerful systems management platform, but today it lacks a native way to automate actions based on events in real time. As a result, administrators often have to write custom scripts to react to things like patch updates or system changes, which adds unnecessary complexity and effort. This project aims to change that by introducing a simple, scalable event-driven architecture that turns Uyuni into an automation-friendly platform. The idea is to make it easy for administrators to connect Uyuni with other tools and build workflows without writing a lot of custom code. The solution has two main parts. First, an MQTT-based event publisher that hooks into Uyuni’s existing event pipeline and emits real-time events such as patch updates, system registrations, and Salt state results. Second, a custom Node-RED integration that allows administrators to visually design automation workflows using a drag-and-drop interface. The publisher is designed to be lightweight and non-intrusive, running as a passive listener so it does not interfere with Uyuni’s current behavior. It sends structured JSON messages, supports topic-based filtering, and includes reliability features like retries, batching, and rate limiting to handle larger deployments. On top of this, the Node-RED layer provides reusable nodes for consuming events, triggering actions, and interacting with Uyuni APIs. Overall, this project makes automation in Uyuni much more accessible, reduces the need for manual scripting, and enables easy integration with external tools like Slack or Jira. It also lays a solid foundation for building more advanced automation features in the future.
