Kubernetes Networking
Kubernetes Networking refers to the set of principles, models, and components that enable communication between pods, services, and external systems within a Kubernetes cluster. It encompasses concepts like the Container Network Interface (CNI), service discovery, load balancing, and network policies to ensure secure and reliable connectivity. This networking model is abstracted from the underlying infrastructure, allowing applications to communicate seamlessly across nodes.
Developers should learn Kubernetes Networking when deploying containerized applications in Kubernetes, as it is essential for microservices architectures, service-to-service communication, and managing traffic flow. It is crucial for scenarios like implementing ingress controllers for external access, configuring network policies for security, and ensuring high availability through load balancing across pods.
