Any way to reduce output from Google Cloud Run emulator?

The Google Cloud Run emulator (gcloud beta code dev) watches for file changes and rebuilds on every change.

So, in my terminal, there's a constant churn of building messages as I type, and it's distracting.

I tried (reference: https://cloud.google.com/sdk/gcloud/reference)

--verbosity="none" (no effect)
--quiet just elminates interactivity.
--no-user-output-enabled crashes the emulator with

Flag --enable-rpc has been deprecated, flags --rpc-port or --rpc-http-port now imply --enable-rpc=true, so please use only those instead
^CException in thread Thread-13:
Traceback (most recent call last):
  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/threading.py", line 932, in _bootstrap_inner
    self.run()

and a whole bunch more that I can copy if it matters.

Is there a way to either silence build logs, but still get (1) my own console.logs and (2) errors?

Solution

I suspect (because your question was the first time I became aware of this [useful] facility) that, because gcloud beta code dev is using (in my case) minikube (locally), the output is being generated by minikube (kubelet) process and not gcloud, that you can't (yet!) control the output by adding gcloud flags.

It's a good suggestion and I recommend you file an issue on Google's Issue Tracker.

kubectl (!) has a new configuration that points to minikube while it's running and (!) I'm able to kubectl logs deployment/${APP} from another term to view only my app's logs:

kubectl get deployments
NAME      READY   UP-TO-DATE   AVAILABLE   AGE
${APP}    1/1     1            1           1m

kubectl logs deployment/${APP}
