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.

Understanding the difference between the master and worker nodes

To run Kubernetes, you will require Linux machines, which are called nodes in Kubernetes. A node could be a physical machine or a virtual machine on a cloud provider, such as an EC2 instance. There are two types of nodes in Kubernetes:

  • Master nodes
  • Worker nodes

Master nodes are responsible for maintaining the state of the Kubernetes cluster, whereas worker nodes are responsible for executing your Docker containers.

While using Linux, you will have probably used commands such as apt-get install or yum install to get a new, fully functional software preconfigured that just works out of the box. With Kubernetes, things are a slightly more complex.

The good news is that you can also use Windows-based nodes to launch Windows-based containers in your Kubernetes cluster. The thing to know is that you can mix Linux and Windows machines on your cluster and it will work the same, but you cannot launch a...
