Investigating Kubernetes Network Errors
You are a container engineer at Cube4Lyf, an e-gaming platform geared towards puzzle and logic games. Your team has been working on migrating Cube4Lyf's first hit title, Cubecraft, into Kubernetes. The portal app should have access to both the game engine pods and the game's shop pods (via services). However, the new network policies are preventing communication. You need to diagnose the issue(s) and restore connectivity.
