This post introduces a new alpha feature gate in Kubernetes v1.35 that changes route reconciliation in the Cloud Controller Manager from a fixed-interval polling model to a watch-based informer model.
•Prior to v1.35, the route controller in CCM reconciled routes at a fixed interval, causing unnecessary cloud provider API requests even when no changes occurred.
•The new feature gate CloudControllerManagerWatchBasedRoutesReconciliation can be enabled with --feature-gate=CloudControllerManagerWatchBasedRoutesReconciliation=true.
•Reconciliation is triggered when a node is added, deleted, or when .spec.podCIDRs or .status.addresses fields are updated.
•An additional reconcile runs at a random interval between 12h and 24h, chosen at controller start time.
•
The feature does not modify the logic inside the reconciliation loop, so existing route configurations remain unaffected.
