Now we have a waypoint proxy installed, we will learn how to split traffic between services.
## Split traffic between services
The Bookinfo application has three versions of the `reviews` service. You can split traffic between these versions to test new features or perform A/B testing.
Let's configure traffic routing to send 90% of requests to `reviews` v1 and 10% to `reviews` v2:
{{< text syntax=bash snip_id=deploy_httproute >}}
$ kubectl apply -f - <<EOF
apiVersion: gateway.networking.k8s.io/v1
kind: HTTPRoute
metadata:
name: reviews
spec:
parentRefs:
- group: ""
kind: Service
name: reviews
port: 9080
rules:
- backendRefs:
- name: reviews-v1
port: 9080
weight: 90
- name: reviews-v2
port: 9080
weight: 10
EOF
{{< /text >}}
To confirm that roughly 10% of the of the traffic from 100 requests goes to `reviews-v2`, you can run the following command:
{{< text syntax=bash snip_id=test_traffic_split >}}
$ kubectl exec deploy/sleep -- sh -c "for i in \$(seq 1 100); do curl -s http://productpage:9080/productpage | grep reviews-v.-; done"
{{< /text >}}
You'll notice the majority of requests go to `reviews-v1`. You can confirm the same if you open the Bookinfo application in your browser and refresh the page multiple times. Notice the requests from the `reviews-v1` don't have any stars, while the requests from `reviews-v2` have black stars.
