Overview of this book

Kubernetes is an open source system to automate the deployment, scaling, and management of containerized applications. If you are running more than just a few containers or want automated management of your containers, you need Kubernetes. This book mainly focuses on the advanced management of Kubernetes clusters. It covers problems that arise when you start using container orchestration in production. We start by giving you an overview of the guiding principles in Kubernetes design and show you the best practises in the fields of security, high availability, and cluster federation. You will discover how to run complex stateful microservices on Kubernetes including advanced features as horizontal pod autoscaling, rolling updates, resource quotas, and persistent storage back ends. Using real-world use cases, we explain the options for network configuration and provides guidelines on how to set up, operate, and troubleshoot various Kubernetes networking plugins. Finally, we cover custom resource development and utilization in automation and maintenance workflows. By the end of this book, you’ll know everything you need to know to go from intermediate to advanced level.

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 kubeadm. 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 still young, and there are different options for each environment. It's not completely trivial to stand up a Kubernetes cluster, but with some effort and attention to detail you can get it done quickly.

In Chapter 3, we will explore the important topics of Monitoring, Logging, and Troubleshooting. Once your cluster is up and running and you start deploying workloads, you need you make sure it runs properly and satisfies requirements. This requires ongoing attention and responding to various failures that happen in the real world.
