I’m doing some chaos testing in K8s. My platform use Istio envoy sidecar, and as some use case of my chaos scenarios, I would like to stop/kill a envoy proxy without kill the service container, and see what is the standard behavior.
So far I don’t manage to figure how to do it through kubectl/istioctl.
Any idea how to accomplish this?
Regards
You might try and configure your Istio Virtual Service with a secondary HTTP route with a Route Destination:
Setting that weight to 100 would activate that fake route, effectively "killing" the router (in that it sends the traffic to "nowhere"), while the service remains active.
Use the /quitquitquit endpoint:

curl -sf -XPOST http://127.0.0.1:15020/quitquitquit
