Endigest AI Core Summary
The Node Readiness Controller is a new Kubernetes project that extends node scheduling readiness beyond the standard binary 'Ready' condition using declarative taint management.
•Introduces the NodeReadinessRule (NRR) API to define custom scheduling gates for specific node groups and heterogeneous clusters
•Supports two enforcement modes: continuous enforcement (monitors throughout the node lifecycle) and bootstrap-only enforcement (for one-time initialization steps)
•Reacts to Node Conditions rather than performing health checks itself, enabling integration with Node Problem Detector and custom solutions
•Includes a dry run mode to simulate taint actions and validate impact before enforcing rules across a fleet
•Example use case shows CNI bootstrapping where a node stays unschedulable until a custom NetworkReady condition is met
