Introduction

In the previous chapters, we’ve looked at some Kubernetes objects that are used to deploy and run applications. We looked at Pods as the most fundamental unit for deploying microservices applications; then we looked at Deployment controllers that add things like scaling, self-healing, and rolling updates. However, despite all of the benefits of Deployments, we still cannot rely on individual Pod IPs! This is where Kubernetes Service objects come into play – they provide stable and reliable networking for a set of dynamic Pods.
