🔹 Kubernetes - Kubernetes v1.34: Decoupled Taint Manager Is Now Stable

The blog post discusses the stabilization of the decoupled taint manager in Kubernetes v1.34. This update separates the responsibilities of managing node lifecycle and pod eviction into two different components. Previously, the node lifecycle controller was responsible for both marking nodes as unhealthy with NoExecute taints and evicting pods. Now, a dedicated taint eviction controller handles evictions, while the node lifecycle controller focuses on applying taints. This separation improves code organization and allows for easier enhancements or custom implementations of the taint-based eviction process. The feature gate SeparateTaintEvictionController has reached general availability, and users have the option to disable taint-based eviction. More information can be found in the KEP and previous announcements. The post also acknowledges contributors who helped develop this feature. 👉 Read more
