Kubernetes Networking

Summary

Every Pod gets its own IP address, and Kubernetes provides a flat network model where Pods can communicate across nodes — a different mental model from Docker's default single-host networking.

• 1Learn the basic Kubernetes networking model: every Pod gets a unique, routable IP.
• 2Practice using a Service's DNS name to reach another Pod, rather than a hardcoded IP.
• 3Understand this networking model is what makes Services and load balancing possible across a whole cluster.
