Overview of this book

The fourth edition of the bestseller Mastering Kubernetes includes the most recent tools and code to enable you to learn the latest features of Kubernetes 1.25. This book contains a thorough exploration of complex concepts and best practices to help you master the skills of designing and deploying large-scale distributed systems on Kubernetes clusters. You’ll learn how to run complex stateless and stateful microservices on Kubernetes, including advanced features such as horizontal pod autoscaling, rolling updates, resource quotas, and persistent storage backends. In addition, you’ll understand how to utilize serverless computing and service meshes. Further, two new chapters have been added. “Governing Kubernetes” covers the problem of policy management, how admission control addresses it, and how policy engines provide a powerful governance solution. “Running Kubernetes in Production” shows you what it takes to run Kubernetes at scale across multiple cloud providers, multiple geographical regions, and multiple clusters, and it also explains how to handle topics such as upgrades, capacity planning, dealing with cloud provider limits/quotas, and cost management. By the end of this Kubernetes book, you’ll have a strong understanding of, and hands-on experience with, a wide range of Kubernetes capabilities.

Helm alternatives

Helm is battle tested and very common in the Kubernetes world, but it has its downsides and critics, especially when you develop your own charts. A lot of the criticism was about Helm 2 and its server-side component, Tiller. However, Helm 3 is not a panacea either. On a large scale, when you develop your own charts and complex templates with lots of conditional logic and massive values files, it can become very challenging to manage.

If you feel the pain, you may want to investigate some alternatives. Note that most of these projects focus on the deployment aspect. Helm’s dependency management is still a strength. Let’s look at some interesting projects that you may want to consider.

Kustomize

Kustomize is an alternative to YAML templating by using the concept of overlays on top of raw YAML files. It was added to kubectl in Kubernetes 1.14.

See https://github.com/kubernetes-sigs/kustomize.
