karmada v1.3.0 release

What's New

Taint-based eviction in graceful way

We introduced a new controller named taint manager which aims to evict workloads from faulty clusters after a grace period.
Then the scheduler would select new best-fit clusters for the workloads. In addition, if the feature GracefulEviction is enabled,
the eviction will be very smooth, that is, the removal of evicted workloads will be delayed until the workloads are available on
new clusters or reach the maximum grace period. For more details please refer to Failover Overview.

Global proxy for resources across multi-clusters

We introduced a new proxy feature to karmada-search that allows users to access resources in multiple clusters in a way just like accessing resources in a single cluster. No matter whether the resources are managed by Karmada, by leveraging the proxy, users
can manipulate the resources from the Karmada control plane.
For more details please refer to Global Resource Proxy.

(Feature contributor: @ikaven1024, @XiShanYongYe-Chang)

Cluster resource modeling

To provide a more accurate scheduling basis for the scheduler, we introduced a way to model the cluster's available resources.
The cluster status controller will model the resources as per the customized resource models, which is more accurate than the general resource summary. For more details please refer to Cluster Resource Modeling.

(Feature contributor: @halfrost, @Poor12)

Bootstrap token-based cluster registration

Now for clusters in Pull mode, we provide a way for them to register with the Karmada control plane. By leveraging the commands token and register in kubectl, the registration process including deploying the karmada-agent can be completed very easily. For more details please refer to Register cluster with Pull mode.

(Feature contributor: @lonelyCZ )

Significant improvement in system scalability

We improved the system scalability, such as:

• Enable pprof(#2008)
• Introduce cachedRESTMapper(#2187)
• Adopt the transform function to reduce memory usage(#2383)

With these improvements, Karmada can easily manage hundreds of huge clusters. The detailed test report will be released soon.
