Overview of this book

The third edition of Mastering Kubernetes is updated with the latest tools and code enabling you to learn Kubernetes 1.18’s latest features. This book primarily concentrates on diving deeply into complex concepts and Kubernetes best practices to help you master the skills of designing and deploying large clusters on various cloud platforms. The book trains you to run complex stateful microservices on Kubernetes including advanced features such as horizontal pod autoscaling, rolling updates, resource quotas, and persistent storage backend. With the two new chapters, you will gain expertise in serverless computing and utilizing service meshes. As you proceed through the chapters, you will explore different options for network configuration and learn to set up, operate, and troubleshoot Kubernetes networking plugins through real-world use cases.

Summary

In this chapter, we got into some hands-on cluster creation. We created a single-node cluster using Minikube and a multi-node cluster using KinD and k3d. Then, we looked at the many options to create Kubernetes clusters on cloud providers. Finally, we touched on the complexities of creating Kubernetes clusters on bare metal. The current state of affairs is very dynamic. The basic components are changing rapidly, the tooling is getting better, and there are different options for each environment. Kubeadm is now the cornerstone of most installation options, which is great for consistency and consolidation of effort.

It's still not completely trivial to stand up a Kubernetes cluster on your own, but with some effort and attention to detail, you can get it done quickly.

In the next chapter, we will explore the important topics of scalability and high availability. Once your cluster is up and running, you need to make sure it stays that way, even as the volume of requests increases. This requires ongoing attention and building the ability to recover from failures, as well as adjusting to changes in traffic.
