caas-team/GoKubeDownscaler v1.3.0

on GitHub

🎉Announcement 🎉

We are pleased to announce the release of version 1.3.0 of GoKubeDownscaler. This release represents a significant milestone as it officially brings the project to GA and brings it into feature parity with the original, popular PyKubeDownscaler written in Python.

🚀 Release Notes 🚀

• All py-kube-downscaler features are now available in GoKubeDownscaler
• Introduction of Metrics: Starting today, GoKubeDownscaler exposes a series of metrics that can be used for production alerts, general statistics, and tracking of CPU and memory savings. Metrics can be exposed using the --metrics argument.
• Performance Optimizations: GoKubeDownscaler introduces new quality-of-life performance improvements. API calls have been optimized and reduced, multithreaded execution has been introduced, leveraging Go's native parallelism. Resource usage has been minimized, especially during idle situations.
• Webhook Introduction: An optional webhook has been introduced that can perform scaling during resource admission phases. This is very useful for ensuring cluster compliance and avoiding unnecessary scale-ups that could occur if a resource is deployed between two KubeDownscaler cycles. The webhook can be installed via Helm Chart.
• Regulated API Server Access: GoKubeDownscaler now natively supports and customizes QPS and Burst values to avoid saturating the API Server during downscaling peaks. The user can adjust these values using the --qps and --burst arguments.
• Introducing JSON Logs: GoKubeDownscaler can now print logs in JSON format using the --json-logs argument.
