karmada v0.5.0 release

What's New

Support resource status aggregation from Karmada
Users are now able to query aggregated status of resources(propagated by Karmada) from Karmada API-server, no need to connect to each member cluster.
All resource's status in member clusters will be aggregated to its binding objects.
In addition, if the resource type is deployment, deployment status will be also reflected.

karmada-agent to support pull-based synchronization between control plan and member clusters
karmada-agent is introduced in this release to support cases the member clusters not directly reachable from the Karmada control plan.
The agent basically pulls all useful configurations from the Karmada control plane and applies to member clusters it serves.
The karmada-agent also completes cluster registration automatically.

ReplicaSchedulingPolicy API to customize replica scheduling constraints of Deployments
Users are now able to customize replica scheduling constraints of Deployments with ReplicaScheduling Policy API.
The replicas will be divided into different numbers for member clusters according to weight list indicated by the policy.

Other Notable Changes

• The label karmada.io/override and karmada.io/cluster-override have been deprecated and replaced by policy.karmada.io/applied-overrides and policy.karmada.io/applied-cluster-overrides to indicate applied override rules.
• The ResourceBinding and ClusterResourceBinding names now consist of resource kind and resource name.
• Both PropagationPolicy and ClusterPropagationPolicy names now restricted to no more than 63 characters.
• OverridePolicy and ClusterOverridePolicy changes will take effect immediately now.
• Users are now able to use new flag --cluster-status-update-frequency when configuring karmada-agent and karmada-controller-manager, to specify cluster status update frequency.

karmada v0.4.0 release

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.

Other Notable Changes

• The PropagationWork API is now Work and located at the work.karmada.io group.
• The PropagationBinding API is now ResourceBinding and located at the work.karmada.io group.
• The label karmada.io/driven-by has been deprecated and replaced by propagationpolicy.karmada.io/namespace, propagationpolicy.karmada.io/name, and clusterpropagationpolicy.karmada.io/name.
• The label karmada.io/created-by has been deprecated and replaced by propagationpolicy.karmada.io/namespace, propagationpolicy.karmada.io/name, clusterpropagationpolicy.karmada.io/name, resourcebinding.karmada.io/namespace, resourcebinding.karmada.io/name, clusterresourcebinding.karmada.io/name, work.karmada.io/namespace, work.karmada.io/name.
• Added new annotation policy.karmada.io/applied-placement for both ResourceBinding and ClusterResourceBinding resources, to indicate the placement rule.
• Added Validating Admission Webhook to restrict resource selector change for PropagationPolicy and ClusterPropagationPolicy objects.

karmada v0.3.0 release

What's New

Support override resources when propagating to member clusters

Users are now able to specify override policies to customize specific resource fields for different clusters. (#130, @RainbowMango, @mrlihanbo)

Support labelselector in cluster affinity

Users are now able to use ClusterAffinity.LabelSelector in PropagationPolicy API to restrict target clusters to when propagating resources. (#149, @mrlihanbo)

Support spread constraints

Users are now able to specify resource spread constraints in propagation policies:

• SpreadByFieldCluster: resource will be spread by clusters, it's useful for limiting number of clusters that a resource will be propagated to. (#162, #167, @kevin-wangzefeng , #168, @mrlihanbo)

More constraint options will be introduced in the later releases:

• SpreadByFieldRegion: resource will be spread by region.
• SpreadByFieldZone: resource will be spread by zone.
• SpreadByFieldProvider: resource will be spread by cloud providers.

Added webhook components to mutating and validating resources automatically
Introduced new components named karmada-webhook for implementating Mutating and Validationg webhooks. (#133, @RainbowMango)

Other Notable Changes

• E2E testing time consumption has been significantly reduced. (#119, @mrlihanbo)
• Provided generic client for operating both Kubernetes and Karmada APIs. (#126, @RainbowMango)
• The MemberCluster API is now Cluster. (#139, @kevin-wangzefeng)
• The API group propagationstrategy.karmada.io is now policy.karmada.io. (#142, @kevin-wangzefeng)
• Supported skip member cluster TLS verification. (#159, @mrlihanbo)
• Any unexpected modification of resource in member cluster will be amended automatically. (#127, @mrlihanbo)
