How would you verify that a newly created Route is correctly exposing your application?

• A. Open the Route in a browser using the cluster IP.
• B. Retrieve the Route host with oc get routes, wait for DNS to resolve, then curl the Route host and check the response.
• C. Use oc describe route and assume it's exposed.
• D. Use oc expose service to create a new route.

Answer: (B)

End-to-end verification that a Route exposes the application by resolving the Route’s host and making a real HTTP request to that hostname. The Route object defines an externally reachable host through the cluster’s router, so the true test is to confirm you can reach that host from outside or from a client machine and receive the expected response. First, list the routes to obtain the exact host name assigned to your Route, which you can then use to perform a request. If you need to, wait for the DNS for that host to propagate so the name actually resolves to the router’s IP. Once DNS resolves, curl the Route host (using the appropriate protocol, http or https) and verify you see the expected status code and content. This end-to-end check confirms the Route is correctly exposing the application because it validates the actual network path from a client to the service through the OpenShift router.

Opening the Route via the cluster IP isn’t reliable for external access since Routes are designed to be reached by DNS-hostnames managed by the cluster’s DNS, not by internal cluster IPs. Simply describing the Route doesn’t prove reachability, you must verify the real connection works. Creating a Route with the expose command is how you set up exposure, not how you verify it.
