Key benefits

  • Develop a holistic understanding of operators and the Operator Framework
  • Learn to design and develop your own operators as per industry standards
  • Find out how to implement best practices and troubleshoot Kubernetes operators

Description

From incomplete collections of knowledge and varying design approaches to technical knowledge barriers, Kubernetes users face various challenges when developing their own operators. Knowing how to write, deploy, and pack operators makes cluster management automation much easier – and that's what this book is here to teach you. Beginning with operators and Operator Framework fundamentals, the book delves into how the different components of Operator Framework (such as the Operator SDK, Operator Lifecycle Manager, and OperatorHub.io) are used to build operators. You’ll learn how to write a basic operator, interact with a Kubernetes cluster in code, and distribute that operator to users. As you advance, you’ll be able to develop a sample operator in the Go programming language using Operator SDK tools before running it locally with Operator Lifecycle Manager, and also learn how to package an operator bundle for distribution. The book covers best practices as well as sample applications and case studies based on real-world operators to help you implement the concepts you’ve learned. By the end of this Kubernetes book, you’ll be able to build and add application-specific operational logic to a Kubernetes cluster, making it easier to automate complex applications and augment the platform.

Who is this book for?

This book is for DevOps and cloud engineers, Kubernetes engineers, SREs, developers, and cloud architects interested in automating the management of their Kubernetes clusters. It assumes a basic understanding of core Kubernetes topics or familiarity with Kubernetes and container orchestration.

What you will learn

  • Gain insight into the Operator Framework and the benefits of operators
  • Implement standard approaches for designing an operator
  • Develop an operator in a stepwise manner using the Operator SDK
  • Publish operators using distribution options such as OperatorHub.io
  • Deploy operators using different Operator Lifecycle Manager options
  • Discover how Kubernetes development standards relate to operators
  • Apply knowledge learned from the case studies of real-world operators

This is a book that tells you not just how to develop a k8s operator but how to iteratively develop an operator to achieve increasing levels of sophistication. The code is meticulously described and broken up into digestible chunks. It's almost like having someone next to you walking through the code.

Having read the book before it was released, there may be some slight differences from the published version.Our team looked at writing and managing custom operators instead of just managing Openshift clusters at one time. To learn more, we picked this book.Operators are designed to automate tasks that would otherwise be performed by humans manually, such as cluster and application management.Our goal is to solve the following tasks:* Testing your cluster's resilience by simulating failure in all or part of it* Making backups of the state of the application and restoring them The book gives an in-depth look at how operators interact with K8s, how to design and deploy them. (particularly chapters 3 to 7).There are quite a few examples and supplementals in the Github repository.Anyone interested in learning more about K8s operators and starting to design and write one should read this book.

Review of Kubernetes Operator Framework Book by Michael DameThsi book is an introduction to the Kubernetes Operator structure for users who are unfamiliar with that and how it benefits the DevOps space.In the first chapter the author discusses the essentials of Operators and the operator framework. The principal idea behind an operator is to automate the cluster creation and application management tasks that typically would be done by a human. Any operator is essentially just a controller. The operator SDKs are submitted to OperatorHub.io for users to download the code from one single location.The above diagram gives an overview of the operator sdk, operator and the OperatorHub.io website.The chapter 2 and chapter 3 focus on designing and developing an Operator.Chapter 3 talks about error reporting and reporting errors with events. How to process them. In chapter 4 the author provides the steps for developing an operator with Operator SDK. In chapter 5 Developing an Operator Advanced functionality the author dives deep into the implementation of the operator. In chapter 6 the author talks about the details of building the operator. How to write the controller loop code? What are the characteristics of the controller loop? In chapter 7 the use of OLM (Operator lifecycle Manager) is described. Installing Grafana operator is taken as an example to highlight the use of Operator hub. The steps to submit your own operator to the OperatorHub.io are explained.Overall I would highly recommend this book for a novice who is trying to learn Kubernetes operator and write their own and submit the code to OperatorHub.io.great book!

This a wonderful book for the one who wants to start the journey of Kubernetes and also one who is a professional working on this, this book gives insights to all, in this world of over information this book precisely guides you as what you need and where to look up for things to work, I was a novice but was able to understand through and through about Kubernetes, I say every technical person needs to read this as this is a every day diction for Kubernetes frame works and operators. Please keep up the good work and bring more valuable work like this to us!!!!! Keep going !!!!!

Being one of the maintainers of Operator Framework projects, I can vouch for the simplicity and accuracy of this book. Though the community projects have technical documentation, afaik there is no content currently anywhere which walks a user through the utilities of all tools in one go. The author has elaborately explained the end to end process of creating operators, building and packaging them, and submitting it to OLM to manage its lifecycle. The chapters are thoroughly organized to make it easier for a beginner or an expert to refer this book for understanding concepts.Personally, I especially like the idea where the author tackles the pitfalls which an operator author can face. These are really useful for someone trying operators out for first time.Overall, a great read! Would highly recommend.
