Istio: Route weight traffic to replica pods of a deployment

Question

I have a deployment with 7 replica pods. In replica pods I give manual some labels version: ${nodeName}. After create virtual services and destination rules,but nothing happens. Also I can not see versioning traffic split in kiali. For destination rules Kiali said that can't find labels for host.

Is there another way to achieve traffic management to replica pods in a deployment?

This is my yaml files
