ovnkube does not generate persistent network configs #274

I also encountered similar problems....

The following is my environment and steps

1. rhel 9.2 os ( 3 master , 3 worker )
2. install openvswitch , crio , kubectl , kubelet , kubeadm ,
3. kubeadm init ( init cluster )
4. install ovn-kubernetes with helm ( use values-multi-node-zone.yaml with default mode )
5. i got ( ovnkube-control-plane pod , ovnkube-db pod , ovnkube-master pod , ovnkube-node pod , ovs-node pod )

I get the following IP :
