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.

Chapter 8: Managing Namespaces in Kubernetes

So far, we've learned about Kubernetes' key concepts by launching objects into our clusters and observing their behavior. As you deployed all of these objects, such as Pods, ConfigMaps, Secrets, and more, you may have noticed that, in the long run, it would be difficult to maintain a cleanly organized cluster. As your clusters grow, it's going to become more and more difficult to maintain the ever-increasing number of resources that are managed in your cluster. That's when Kubernetes namespaces come into play.

In this chapter, we will learn about namespaces. They help us keep our clusters well organized by grouping our resources by application or environment. Kubernetes namespaces are another key aspect of Kubernetes management and it's really important to master them!

In this chapter, we're going to cover the following main topics:

  • Introduction to Kubernetes namespaces
  • How namespaces impact...
