1.11.3 Cluster Networking

Описание: Summary of article: https://kubernetes.io/docs/concepts/c.... The article is about: Kubernetes uses networking for communication, addressing highly-coupled, pod-to-pod, pod-to-service, and external communication issues in clusters.

It involves sharing machines across applications without port conflicts, ensuring non-overlapping IP addresses for pods, services, and nodes.

Clusters can be IPv4 only, IPv6 only, or dual-stack, determined by network plugin and configurations.

The Kubernetes network model is implemented through Container Network Interface (CNI) plugins on each node, with various capabilities and add-ons available.
