Dependency Watchdog
Overview
A watchdog which actively looks out for disruption and recovery of critical services. If there is a disruption then it will prevent cascading failure by conservatively scaling down dependent configured resources and if a critical service has just recovered then it will expedite the recovery of dependent services/pods.
Avoiding cascading failure is handled by Prober component and expediting recovery of dependent services/pods is handled by Weeder component. These are separately deployed as individual pods.
Current Limitation & Future Scope
Although in the current offering the Prober is tailored to handle one such use case of kube-apiserver connectivity, but the usage of prober can be extended to solve similar needs for other scenarios where the components involved might be different.

Feedback and Support

Please report bugs or suggestions on how we can enhance dependency-watchdog to address additional recovery scenarios on GitHub issues
