What is a pod network?

Pod Networks refer to the way networking is implemented for pods in a Kubernetes cluster. A pod network enables communication between pods across different nodes and ensures that each pod gets its own unique IP address within the cluster. These networks are typically managed by network plugins, also called Container Network Interfaces (CNIs), such as Calico, Flannel, or Weave. Proper configuration of a pod network is crucial for service discovery, load balancing, and secure communication between microservices within a Kubernetes environment.
