Monitoring
- Improve kube-ovn-pinger metrics to check apiserver and dns
- Add kube-ovn-controller metrics to show the controller status
- Add grafana templates to visualize metrics
Performance
- Adjust client-go param to increase parallelism
- Adjust ovn-db and ovn-controller resource
- Merge some ovn-nb requests and remove most wait=ovn-nb params
Stability and Bugfix
- LB init conflict when use multiple kube-ovn-controller
- Static Route might lost during leader election
- If pod have not a status.PodIP skip add/del static route
- Add keepalive to ovn-controller
- Add qlen when set egress QoS
- Add ingress_policing_burst to accurate limit ingress bandwidth
- GC resources when kube-ovn-controller starts
- Re-annotate related namespaces when subnet deleted.
- Check the short name of kubernetes services which is independent of the cluster domain name
- Daemonset updateStrategy changes to OnDelete for grace update
- Use new upstream ovn with some kube-ovn related modification
