v1.6.0

What's New

Support Kubernetes up to V1.30

“k8s.io/xxx” and all its related dependencies are upgraded to version “v0.30.6”, for ensuring OpenYurt is compatible with Kubernetes v1.30 version. This compatibility has been confirmed by an end-to-end (E2E) test where we started a Kubernetes v1.30 cluster using KinD and deployed the latest components of OpenYurt. #2179 #2249

Enhance edge autonomy capabilities

OpenYurt already offers robust edge autonomy capabilities, ensuring that applications on edge nodes can continue to operate even when the cloud-edge network is disconnected. However, there are several areas where the current edge autonomy capabilities can still be improved. For instance, once nodes are annotated with autonomy annotations, the cloud controller does not automatically evict Pods, regardless of whether the disconnection is due to cloud-edge network issues or node failures, yet users expect automatic Pod eviction during node failures. Additionally, the current edge autonomy capabilities cannot be directly used in managed Kubernetes environments because users cannot disable the NodeLifeCycle controller within the Kube-Controller-Manager component of managed Kubernetes. In this release, new endpoints/endpointslices webhooks are added to ensure that pods are not removed from the backend of the Service. Additionally, a new autonomous annotation is introduced, supporting the configuration of autonomous time. #2155 #2201 #2211 #2218 #2241

Node-level Traffic Reuse Capability

In an OpenYurt cluster, control components are deployed in the cloud, and edge nodes usually interact with the cloud through the public internet, which can lead to significant consumption of cloud-edge traffic. This problem is more pronounced in large-scale clusters, mainly due to the edge-side components performing full-scale list/watch operations on resources. This not only consumes a large amount of cloud-edge traffic but also places considerable pressure on the apiserver due to the high volume of list operations. In this release, We have added a traffic multiplexing module in YurtHub. When multiple clients request the same resource (services, endpointslices), YurtHub returns data from the local cache, reducing the number of requests to the apiserver. #2060 #2141 #2242
