Repair Service Discovery

Restore traffic between a frontend and its backend Service.

A intermediate Linux challenge worth 10 points. Solve it hands-on in a real Linux environment in your browser - no local setup, no fake shells.

The Challenge

Scenario: frontend cannot reach http://catalog. Inspect the Service, backend labels/ports, and Endpoints.

Fix catalog-service.yaml so the selector targets the backend and targetPort reaches its container. Apply it and prove the request with kubectl exec frontend -- curl http://catalog. Run check when done.
