You have a Cloud Run service currently serving 100% of production traffic. You deploy a new revision of the service, but you only want 10% of user traffic to be routed to the new revision for canary testing.

How should you configure this?

Deploy the new revision to a different Cloud Run service and use a Global HTTP Load Balancer to split traffic.

Use the Cloud Console or gcloud to adjust the traffic splitting settings, assigning 90% to the old revision and 10% to the new revision.

Modify the application code to randomly reject 90% of requests.

Cloud Run does not support traffic splitting; you must use GKE for canary deployments.
