How can you configure a Cloud Run application deployment for beta testers before a full rollout?

Deploying the Cloud Run application to production with a revision tag and the "--no-traffic" option allows the application to be available without routing any traffic to it, effectively making it a safe way to share the application with beta testers. By using the "--no-traffic" option, you can ensure that the new version is set up and ready for testing, but no users will access it until you explicitly direct traffic to it later. The revision tag helps in identifying the specific deployment that beta testers will evaluate, ensuring consistency in the test environment.

This method supports controlled testing, as you can share the application URL exclusively with the testing team without impacting the current production environment. It allows for feedback collection and debugging of the application before rolling it out to all users, mitigating risks associated with a wider deployment.

The other options, while they may have their merits, do not provide the same level of control or safety for beta testing. Directing traffic to a newly deployed application, even if limited to 1%, could still affect the user experience for the broader audience. Configuring Google Cloud Armor for IP restrictions would complicate access and doesn't address the need for a controlled test environment effectively. Deploying to a private VM instance, while isolating the
