v1.2.0
What's New
Improve edge autonomy capability when cloud-edge network off
The original edge autonomy feature can make the pods on nodes un-evicted even if node crashed by adding annotation to node,
and this feature is recommended to use for scenarios that pods should bind to node without recreation.
After improving edge autonomy capability, when the reason of node NotReady is cloud-edge network off, pods will not be evicted
because leader yurthub will help these offline nodes to proxy their heartbeats to the cloud via pool-coordinator component,
and pods will be evicted and recreated on other ready node if node crashed.
By the way, The original edge autonomy capability by annotating node (with node.beta.openyurt.io/autonomy) will be kept as it is,
which will influence all pods on autonomy nodes. And a new annotation (named apps.openyurt.io/binding) can be added to workload to
enable the original edge autonomy capability for specified pod.
Reduce the control-plane traffic between cloud and edge
Based on the Pool-Coordinator in the nodePool, A leader Yurthub will be elected in the nodePool. Leader Yurthub will
list/watch pool-scope data(like endpoints/endpointslices) from cloud and write into pool-coordinator. then all components(like kube-proxy/coredns)
in the nodePool will get pool-scope data from pool-coordinator instead of cloud kube-apiserver, so large volume control-plane traffic
will be reduced.
Use raven component to replace yurt-tunnel component
Raven has released version v0.3, and provide cross-regional network communication ability based on PodIP or NodeIP, but yurt-tunnel
can only provide cloud-edge requests forwarding for kubectl logs/exec commands. because raven provides much more than the capabilities
provided by yurt-tunnel, and raven has been proven by a lot of work. so raven component is officially recommended to replace yurt-tunnel.
