Kubernetes v1.36 introduces a new counter metric to optimize route synchronization in the Cloud Controller Manager.
- •The route_controller_route_sync_total metric tracks how many times routes are synced with cloud providers
- •The CloudControllerManagerWatchBasedRoutesReconciliation feature gate switches from fixed-interval polling to watch-based reconciliation
- •Watch-based approach reduces unnecessary API calls to infrastructure providers and relieves rate-limit pressure
- •Operators can use this metric to A/B test and compare sync behavior with the feature gate enabled versus disabled
- •In stable clusters with infrequent node changes, watch-based reconciliation significantly reduces the sync frequency
