Each container within a pod in Kubernetes shares the same network namespace, which means they operate under the same IP address assigned to the pod itself. The pod is the smallest deployable unit in Kubernetes and can contain one or more containers. Because the containers share the pod's network, they communicate with each other via localhost and use the same IP address for network communications.

This design ensures that the containers within a pod are closely coupled, allowing them to efficiently share resources and communicate without the overhead of complex networking configurations. While they can communicate with other pods using their individual IP addresses, the containers inside a single pod will always reference each other using the pod's IP address.

Other options, while they may relate to various concepts within Kubernetes, do not specifically describe how containers within a pod are identified in terms of IP address. Unique IP addresses assigned to individual containers are not utilized in this context, and cluster IPs and service names pertain to networking at a higher abstraction level (e.g., services that manage access to pods) rather than the fundamental communication between containers within the same pod.
