应用virtualservice

[root@k8s-master 06-weight-based-routing]# kubectl apply -f virtualservice-demoapp.yaml 

[root@k8s-master 06-weight-based-routing]# cat virtualservice-demoapp.yaml 
apiVersion: networking.istio.io/v1beta1
kind: VirtualService
metadata:
  name: demoapp
spec:
  hosts:
  - demoapp
  http:
  - name: weight-based-routing
    route:
    - destination:
        host: demoapp
        subset: v10
      weight: 90
    - destination:
        host: demoapp
        subset: v11
      weight: 10

while true; do curl demoapp:8080; sleep 0.$RANDOM; done

可以看到基本是按照9/1进行分配的

也直接vim直接修改VS，然后apply一下，就能在线修改权重了
