karmada v1.4.0 release

What's New

Declarative Resource Interpreter

The Interpreter Framework is designed for interpreting the structure of arbitrary resource types. It consists of built-in and customized interpreters, this release introduced another brand-new customized interpreter.

With the newly introduced declarative interpreter, users can quickly customize resource interpreters for both Kubernetes resources and CRD resources by the rules declared in the ResourceInterpreterCustomization API specification. Compared with the interpreter customized by the webhook, it gets the rules from the declarative specifications instead of requiring an additional webhook component.

The new command named interpret in the karmadactl could be used to test the rules before applying them to the system.
Some examples are provided to help users better understand how this interpreter can be used.

PropagationPolicy/ClusterPropagationPolicy priority

Users are now able to declare the priorities for both PropagationPolicy and ClusterPropagationPolicy. A policy will be applied for the matched resource templates if there are no other policies with higher priority at the point the resource template be processed.

The system administrator can use priorities to manage and control policies. Refer to Configure PropagationPolicy priority for more details.

(Feature contributor: @Garrybest @jwcesign)

Instrumentation improvement

This release enhanced observability significantly through metrics and events.
The metrics can be queried by the endpoint(/metrics) of each component using an HTTP scrap, and they are served in Prometheus format. Events are reported to the relevant resource objects respectively.

Refer to events and metrics for more details.
