How to set log level to info in the ingressgateway pod?


I want to create a Lua filter on my istio-ingressgateway pod, and use the request_handle:logInfo method to log some messages.

For sidecars injected by istio, I know I can use the lua:info annotation to get the info level log.

But the ingressgateway is not a sidecar, so it does not use this annotation.

I guess changing the logLevel value would allow me to see the info logs in the gateway pod. But I only want to change the log level in the gateway pod, not all the istio components.
