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.

Summary

This chapter was one of the most important ones because we discovered how to properly configure our contained applications in Kubernetes.

In particular, we explained why it is so important to decouple your applications from their configuration. Kubernetes in particular emphasizes this principle by differentiating the applications, which are Pods, and their configurations, which are ConfigMaps and Secrets. Use these three objects wisely to build portable applications between environments.

In the next chapter, we will continue discovering Kubernetes by tackling another central concept of Kubernetes, which are Services. Services are Kubernetes objects that allow you to expose your Pods to each other, but also the internet: this is a very important network concept for Kubernetes, and mastering it is essential to use the orchestrator correctly. Fortunately, mastering Services is not very complicated and the next chapter will explain how to achieve this. You will learn how...
