I am trying to capture knative serving behavior in the context of n/w delay/latency. I know istio provides a way to introduce 'fault injection' to simulate the n/w latency and test the app resiliency and since Knative uses Istio as n/w layer (per my setup) .
All I am trying is to introduce somesort of n/w latency as described is [ISTIO documentation][1]
I am having a hard time to find a way to edit the corresponding virtual service as Knative takes care of creating the virtual function when a service is deployed.
Is there any ref or example to guide on how to test knative serving by introducing some sort of latency.
My service deployment file is quite simple
`apiVersion: serving.knative.dev/v1 kind: Service metadata: name: demo-concurrency-kt namespace: aurora spec: template: metadata: annotations: # Target 10 in-flight-requests per pod. autoscaling.knative.dev/metric: concurrency autoscaling.knative.dev/target: "10" autoscaling.knative.dev/targetUtilizationPercentage: "70" spec: containerConcurrency: 0 containers: - image: ghcr.io/knative/autoscale-go:latest
` [1]: https://istio.io/latest/docs/tasks/traffic-management/fault-injection/
I am running everything in docker desktop K8s environment with Istio as my n/w layer
Any help or guidance will be highly appreciated
