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.

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.

Write efficient, smart, and optimized code for containerized applications on public and private clouds at a generic level. This book shows you how to set up microservices that are robust, scalable, and capable of running on GKE (Google Kubernetes Service), AKS (Azure Kubernetes Service), ECS (Elastic Container Service), or even on a vanilla K8S cluster. The book covers the nuts and bolts of container orchestration engines (COEs) and explains how to install and configure them. It also covers creation and deployment of a sample application on COEs. You will learn how to integrate different applications such as OAuth and how to test them and secure them using Istio Citadel. You also will be taught how to create HPA rules for microservices and scale only those microservices that require it, making your stack intelligent. In the concluding chapter, the book explains how to build a SaaS solution from scratch, running on the cloud with automated deployments accessed publicly via a secured ingress K8S controller. By the end of the book, you will have a good understanding of developing microservices and how to design and create a software solution on the cloud. What You Will Learn Build software on Kubernetes in the most optimized way Interact with Kubernetes using client SDKs in Python, Go, nodejs, etc. Create a testing and deployment CI/CD system for software stacks Secure your application using Istio, without writing code Access microservices using ingress controllers and scale them using HPA rules Who This Book Is For Software and system engineers and developers
