What's New

Multiple Scheduling Groups

Users are now able to declare multiple groups of clusters to both PropagationPolicy and ClusterPropagationPolicy by leveraging the newly introduced ClusterAffinities field. The scheduler will evaluate these groups one by one in the order they appear in the specification until it finds the one that satisfies scheduling restrictions.

This feature allows the Karmada scheduler to first schedule applications to lower-cost clusters or migrate applications from a primary cluster to backup clusters in the case of cluster failure.

See multiple scheduling group proposal for more info.

New Way to Customize Scheduler

The default scheduler is now able to work with any number of third-party customized schedulers. Similar to Kubernetes, the workloads will be scheduled by the default scheduler if the scheduler name is not declared in PropagationPolicy or ClusterPropagationPolicy.

See customize scheduler for more details.

Other Notable Changes

API Changes

  • Introduced Affinities to both PropagationPolicy and ClusterPropagationPolicy. (#3105, @RainbowMango)
  • Introduced Placement to the ResoureBinding/ClusterResourceBinding API. (#2702, @Poor12)
  • Introduced SchedulerObservedAffinityName to both ResourceBinding and ClusterResourceBinding. (#3163, @RainbowMango)

Bug Fixes

  • karmadactl: Fixed the issue that karmada-agent installed by the register command cannot delete works due to lack of permissions. (#2902, @lonelyCZ)
  • karmadactl: Fixed the issue that the default ValidatingWebhookConfiguration for resourceinterpreterwebhook was not working. (#2915, @whitewindmills)
  • karmadactl: Fixed the issue that the default ValidatingWebhookConfiguration for resourceinterpretercustomizations was not working. (#2916, @chaunceyjiang)
  • karmadactl: Fixed the error of resources whose name contains colons failed to be created when using karmadactl apply. (#2919, @Poor12)
  • karmadactl init: Granted karmada-agent permissions to access resourceinterpretercustomizations. (#2984, @jwcesign)
  • karmada-controller-manager: Generated PolicyRules from given subjects for impersonation deduplicate. (#2911, @yanfeng1992)
  • karmada-controller-manager/karmada-agent: Fixed the failure to sync work status due to the informer being accidentally shut down. (#2930, @Poor12)
  • karmada-controller-manager/karmada-agent: Fixed misjudgment of deployment and statefuleset health status. (#2928, @Fish-pro)
  • karmada-controller-manager: Fixed LabelsOverrider and AnnotationsOverrider failures to add new items in the case of null label/annotation. (#2971, @chaunceyjiang)
  • karmada-controller-manager: labelsOverrider/annotationsOverrider supports composed-labels, like testannotation/projectId: . (#3037, @chaunceyjiang)
  • karmada-controller-manager: Fixed the issue that RBAC resources whose name contains uppercase characters cannot be propagated. (#3201, @whitewindmills)
  • karmada-agent: Check whether the resource exists before creating it. Sometimes the resource is created in advance, giving less privilege to Karmada. (#2988, @jwcesign)
  • karmada-scheduler: Fixed a corner case that re-scheduling was skipped in the case that the cluster becomes not fit. (#2912, @jwcesign)
  • karmada-search: Filtered out not-ready clusters. (#3010, @yanfeng1992)
  • karmada-search: Avoided proxy request block when member clusters were down. (#3027, @ikaven1024)
  • karmada-webhook: Validated replicaSchedulingType and replicaDivisionPreference. (#3014, @chaunceyjiang)
  • karmada-webhook: Fixed the issue that the InterpretDependency operation cannot be registered. (#3052, @whitewindmills)
  • karmada-search: Supported pod subresource (attach, exec, port-forward) through global proxy. (#3098, @ikaven1024)
