Your company is using HTTPS requests to trigger a public Cloud Run-hosted service accessible at the https://booking-engine-abcdef.a.run.app URL. You need to give developers the ability to test the latest revisions of the service before the service is exposed to customers. What should you do?

  • A. Run the gcloud run deploy booking-engine --no-traffic --tag dev command. Use the https://dev--booking-engine-abcdef.a.run.app URL for testing.
  • B. Run the gcloud run services update-traffic booking-engine --to-revisions LATEST=1 command. Use the https://booking-engine-abcdef.a.run.app URL for testing.
  • C. Pass the curl –H “Authorization:Bearer $(gcloud auth print-identity-token)” auth token. Use the https://booking-engine-abcdef.a.run.app URL to test privately.
  • D. Grant the roles/run.invoker role to the developers testing the booking-engine service. Use the https://booking-engine-abcdef.private.run.app URL for testing.

Selected Answer: A
To enable developers to test the latest revisions of a Cloud Run-hosted service before exposing it to customers, the recommended approach is to use the --no-traffic flag during deployment, as outlined in (Option A). By running the command gcloud run deploy booking-engine --no-traffic --tag dev, you deploy the service with no traffic routed to it initially. Subsequently, developers can test the latest revisions using the URL https://dev--booking-engine-abcdef.a.run.app. This allows for a controlled and private testing environment where developers can validate the service's functionality and behavior before making it publicly accessible. Utilizing a dedicated URL with the --tag option ensures that developers can interact with the specific version intended for testing, facilitating a smooth and secure testing process.

It create a new deployment(revision) with no traffic to https://booking-engine-abcdef.a.run.app but the revision can be tested by developer at https://dev--booking-engine-abcdef.a.run.app as dev tag is associated with the deploymnet.
