Overview of this book

With its broad adoption across various industries, Kubernetes is helping engineers with the orchestration and automation of container deployments on a large scale, making it the leading container orchestration system and the most popular choice for running containerized applications. This Kubernetes book starts with an introduction to Kubernetes and containerization, covering the setup of your local development environment and the roles of the most important Kubernetes components. Along with covering the core concepts necessary to make the most of your infrastructure, this book will also help you get acquainted with the fundamentals of Kubernetes. As you advance, you'll learn how to manage Kubernetes clusters on cloud platforms, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), and develop and deploy real-world applications in Kubernetes using practical examples. Additionally, you'll get to grips with managing microservices along with best practices. By the end of this book, you'll be equipped with battle-tested knowledge of advanced Kubernetes topics, such as scheduling of Pods and managing incoming traffic to the cluster, and be ready to work with Kubernetes on cloud platforms.

Why would you want to expose your Pods?

In the previous chapters, we discussed the microservice architecture, which offers to expose your functionality through REpresentational State Transfer (REST) application programming interfaces (APIs). These APIs rely completely on the HyperText Transfer Protocol (HTTP) protocol, which means that your microservices must be accessible via the web, and thus via an Internet Protocol (IP) address on the network.

In this section, we will explain what Services are in Kubernetes. Next, we'll explain what they're used for and how they can help you expose your Pod-launched microservices.

Understanding Pod IP assignment

To understand what Services are, we need to talk about Pods for a moment once again. On Kubernetes, everything is Pod management: Pods host your applications, and they have a special property. Kubernetes assigns them a private IP address as soon as they are created on your cluster. Keep that in mind because it is super...
