Kubernetes Networking Basics
Learn how pods, services, and ingresses communicate within a Kubernetes cluster and the underlying CNI concepts.
K8s Networking Essentials
Welcome! Kubernetes networking can seem complex, but it's designed to make distributed applications work seamlessly.
In this lesson, we'll explore how different parts of a Kubernetes cluster communicate. You'll learn about Pods, Services, and Ingress.
Pods Get Their Own IPs
In Kubernetes, a Pod is the smallest deployable unit. Each Pod gets its own unique IP address within the cluster.
Containers inside the same Pod share this network namespace, meaning they can communicate with each other using localhost.
