Preface

Chapter 3. Networking, Load Balancers, and Ingress

In this chapter, we will be covering how the Kubernetes cluster handles networking and how it differs from other approaches. We will be describing the three requirements for Kubernetes networking solutions and exploring why these are key to ease of operations. Further, we will take a deeper dive into services and how the Kubernetes proxy works on each node. Finishing up, we will see a brief overview of some higher level isolation features for multitenancy.

This chapter will discuss the following:

  • Kubernetes networking
  • Advanced services concepts
  • Service discovery
  • DNS
  • Namespace limits and quotas
