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 has covered the details of working with Helm and Helm charts. First, you have learned what the purpose of package management is and how Helm works as a package manager for Kubernetes. We have demonstrated how you can install Helm on your local machine, and how you can deploy the WordPress chart to test the installation. Then, we went through the structure of Helm charts, and we have shown how the YAML templates in charts can be configured using user-provided values. Lastly, we have shown the installation of a few popular solutions on a Kubernetes cluster using Helm. We have installed Kubernetes Dashboard, Elasticsearch together with Kibana, and the Prometheus Stack including Grafana.

In the next chapter, we are going to explore authentication and authorization on Kubernetes. We will dive deeper into RBAC available in Kubernetes – which you got a sneak-peek of in this chapter while creating ServiceAccount for accessing Kubernetes Dashboard!
