Book excerpt: "Kubernetes for Python Developers" is the essential guide for developers new to Kubernetes, focusing on a step-by-step approach from application creation to deployment. Written with beginners in mind, it demystifies Kubernetes through a developer's lens, ensuring concepts are accessible and practical. The book includes 30+ exercises with solutions and numerous examples to solidify understanding. Whether you're looking to grasp container orchestration or deploy your Python applications with confidence, this book provides the knowledge and tools needed to navigate the Kubernetes ecosystem effectively. Contents 1. The meta stuff The audience of the book Why developers should learn Kubernetes What we will build What prerequisites you need 2. Containers recap Intro to containers How containers work Container networking Isolating processes Docker compose Docker registry Other container engines 3. Kubernetes 101 Why Kubernetes? How Kubernetes works Components of a Kubernetes cluster Setting up your first cluster 4. Pods 101 Kubectl, kubeconfig How to interact with your cluster Pods, events working with pods 5. Pods 201 Getting inside a pod Pod probes Namespaces Pod networking Deploying your first application 6. Beyond pods Replicasets Deployments Services Full fledged Flask app with Redis 7. Going a notch further Config maps Secrets Init containers Storing persistent data 8. A more robust setup Stateful sets Service accounts and RBAC Ingress annotations 9. Closing thoughts Setting up a CD pipeline in Github Github actions Where to go from here Appendix A: Troubleshooting common scenarios Pod not coming up Correct labels Exposing ports Resource constraints Unauthorized Appendix B: Solutions to exercises Is this the right book for you? This book aims to bridge the gap between Python development and Kubernetes operations, making it an ideal read for anyone in the software development lifecycle seeking to adopt Kubernetes for Python applications. This includes python developers, beginners to Kubernetes, students and educators. Whom is this book NOT for? If you already know Kubernetes and are using it in some capacity, then you might not find any value in this book. Also, if you don't have much of a technical background(don't know how to work with Python, no idea about containers), then this book won't be a good fit for you. About me I'm a full stack developer with more than 2 decades of experience working with enterprise customers. I've been dabbling with Kubernetes since 2018, when there were comparitively lesser resources to tame the Kubernetes beast. I always wanted to read a book to bridge the knowledge gap for a developer who knows a bit of ops and wants to dip their toes in the Kubernetes waters and figured I'll write one for those who are on the same boat. Is the book ideal only for Python developers? IThe book has been written using a Python Flask application as an example. It is quite easy to fit in your Node.js/Java/PHP/Rails/Golang/Rust stack if you understand the concepts explained in the book.

Available in PDF, EPUB and Kindle. Book excerpt: A developer's field-guide to designing scalable services using Kubernetes Key Features Develop and run your software using containers within a Kubernetes environment Get hands-on experience of using Kubernetes with DevOps concepts such as continuous integration, benchmark testing, monitoring, and so on Pragmatic example-based approach showing how to use Kubernetes in the development process Book Description Kubernetes is documented and typically approached from the perspective of someone running software that has already been built. Kubernetes may also be used to enhance the development process, enabling more consistent testing and analysis of code to help developers verify not only its correctness, but also its efficiency. This book introduces key Kubernetes concepts, coupled with examples of how to deploy and use them with a bit of Node.js and Python example code, so that you can quickly replicate and use that knowledge. You will begin by setting up Kubernetes to help you develop and package your code. We walk you through the setup and installation process before working with Kubernetes in the development environment. We then delve into concepts such as automating your build process, autonomic computing, debugging, and integration testing. This book covers all the concepts required for a developer to work with Kubernetes. By the end of this book, you will be in a position to use Kubernetes in development ecosystems. What you will learn Build your software into containers Deploy and debug software running in containers within Kubernetes Declare and add configuration through Kubernetes Define how your application fits together, using internal and external services Add feedback to your code to help Kubernetes manage your services Monitor and measure your services through integration testing and in production deployments Who this book is for If you are a full-stack or back-end software developers interested, curious, or being asked to test as well as run the code you're creating, you can leverage Kubernetes to make that process simpler and consistent regardless of where you deploy. If you're looking for developer focused examples in NodeJS and Python for how to build, test, deploy, and run your code with Kubernetes, this is perfect for you.

Book excerpt: Operators are a way of packaging, deploying, and managing Kubernetes applications. A Kubernetes application doesn’t just run on Kubernetes; it’s composed and managed in Kubernetes terms. Operators add application-specific operational knowledge to a Kubernetes cluster, making it easier to automate complex, stateful applications and to augment the platform. Operators can coordinate application upgrades seamlessly, react to failures automatically, and streamline repetitive maintenance like backups. Think of Operators as site reliability engineers in software. They work by extending the Kubernetes control plane and API, helping systems integrators, cluster administrators, and application developers reliably deploy and manage key services and components. Using real-world examples, authors Jason Dobies and Joshua Wood demonstrate how to use Operators today and how to create Operators for your applications with the Operator Framework and SDK. Learn how to establish a Kubernetes cluster and deploy an Operator Examine a range of Operators from usage to implementation Explore the three pillars of the Operator Framework: the Operator SDK, the Operator Lifecycle Manager, and Operator Metering Build Operators from the ground up using the Operator SDK Build, package, and run an Operator in development, testing, and production phases Learn how to distribute your Operator for installation on Kubernetes clusters

Book excerpt: The way developers design, build, and run software has changed significantly with the evolution of microservices and containers. These modern architectures use new primitives that require a different set of practices than most developers, tech leads, and architects are accustomed to. With this focused guide, Bilgin Ibryam and Roland Huß from Red Hat provide common reusable elements, patterns, principles, and practices for designing and implementing cloud-native applications on Kubernetes. Each pattern includes a description of the problem and a proposed solution with Kubernetes specifics. Many patterns are also backed by concrete code examples. This book is ideal for developers already familiar with basic Kubernetes concepts who want to learn common cloud native patterns. You’ll learn about the following pattern categories: Foundational patterns cover the core principles and practices for building container-based cloud-native applications. Behavioral patterns explore finer-grained concepts for managing various types of container and platform interactions. Structural patterns help you organize containers within a pod, the atom of the Kubernetes platform. Configuration patterns provide insight into how application configurations can be handled in Kubernetes. Advanced patterns covers more advanced topics such as extending the platform with operators.
