Kubernetes DNS provides a streamlined way for pods to discover one another using short, user-friendly names, keeping complex IP addresses out of sight. Yet, this very convenience can mask a significant security flaw. Without a thorough grasp of Kubernetes DNS behavior, an opening for attackers might unknowingly be created. Consider this: the ability to create namespaces and services allows an attacker to reroute traffic intended to leave a cluster, diverting it for their own purposes.
