Understanding Kubernetes Networking. Part 1: Container Networking

Kubernetes is all about networking. In this series, we will examine various aspects of Kubernetes networking such as cluster and POD networks, Container Network Interface (CNI), services, and network policies. To get started though we need to have a basic understanding of the OSI network model, network appliances (physical and virtual), overlay networks, and container networking fundamentals. In this first installment, we will cover those basics. Hope you will me join in this journey.
