karmada v0.4.0 release

on GitHub

What's New

New policy APIs have been added to support cluster level resources propagation and customization
Users are now able to use ClusterPropagationPolicy to propagate both cluster-scoped and namespace-scoped resources. In addition, users are able to use ClusterOverridePolicy to define the overall policy to realize differentiation propagation.

Support resource and policy detector
The detector watches both resources and policy (PropagationPolicy and ClusterPropagationPolicy) changes, all changes on resources or policies will take effect immediately.

Namespace Auto-provision feature get on board
Namespaces created on Karmada will be synced to all member clusters automatically. Users don't need to propagate namespaces anymore.

Scheduler now able to reschedule resources when policy changes
Once the Placement rule in the PropagationPolicy changed, the scheduler will reschedule to meet the declaration.

Scheduler now support failure recovery
Once any of the clusters becomes failure, the scheduler now able to re-schedule the resources to available clusters.
This feature is controlled by flag --failover and disabled by default.
