11 months ago This config looks correct to me, it should be mirroring any traffic that matches that prifix to the canary but it will still send it to the stable that is what mirroring is suppose to do. It is also configured to mirror 100% of the traffic to the canary from this config. Then any traffic that does not match the prefix falls into the next mataching route, istio priorities route config by order.
Tried to use mirroe route option using url prefix , but durring canary deployment there is a route rule getting updated in the virtualservice which specifies that 100% traffic to go to stable service, is there any option to speficy that for all the request marching the URL prefix, it should go only to the anary service and not the stable service.
