Please refer to CHANGELOG v1.8 for a full list of features in this release

Release Highlights​

Active-Active HA Support of CloudCore for Large Scale Cluster [Beta]​

CloudCore now supports Active-Active HA mode deployment, which provides better scalability support for large scale clusters. Cloud-Edge tunnel can also work with multiple CloudCore instances. CloudCore now can add the iptable rules for Cloud-Edge tunnel automatically.

Refer to the links for more details. (#1560, #2999)

EdgeMesh Architecture Modification​

EdgeMesh now has two parts: edgemesh-server and edgemesh-agent. The edgemesh-server requires a public IP address, when users use cross lan communication, it can act as a relay server in the LibP2P mode or assist the agent to establish p2p hole punching. The edgemesh-agent is used to proxy all application traffic of user nodes, acts as an agent for communication between pods at different locations.

Refer to the links for more details. (edgemesh#19)

EdgeMesh Cross LAN Communication​

Users can use cross LAN communication feature to implement cross LAN edge to edge application communication and cross LAN edge to cloud application communication.

Refer to the links for more details. (edgemesh#26, edgemesh#37, edgemesh#57)

Onvif Device Mapper​

Onvif Device Mapper with Golang implementation is provided, based on new Device Mapper Standard. Users now can use onvif device mapper to manage the ONVIF IP camera.

Refer to the links for more details. (mappers-go#48)

Kubernetes Dependencies Upgrade​

Upgrade the vendered kubernetes version to v1.21.4, users now can use the feature of new version on the cloud and on the edge side.

Refer to custom message deliver for more details. (#2413)

Simplified Application Autonomy Configuration When Node Is Off-line​

If user wants any application to stay on edge nodes when disconnected to the cloud, simply add label app-offline.kubeedge.io=autonomy to its pods. KubeEdge will automatically override pod default toleration configuration for Taint node.kubernetes.io/unreachable to avoid Kubernetes evicting pods from unreachable nodes. (#2499)

New home for Device Mappers code​
