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.

Legend has it that Google deploys over two billion application containers a week. How’s that possible? Google revealed the secret through a project called Kubernetes, an open source cluster orchestrator (based on its internal Borg system) that radically simplifies the task of building, deploying, and maintaining scalable distributed systems in the cloud. This practical guide shows you how Kubernetes and container technology can help you achieve new levels of velocity, agility, reliability, and efficiency. Authors Kelsey Hightower, Brendan Burns, and Joe Beda—who’ve worked on Kubernetes at Google and other organizatons—explain how this system fits into the lifecycle of a distributed application. You will learn how to use tools and APIs to automate scalable distributed systems, whether it is for online services, machine-learning applications, or a cluster of Raspberry Pi computers. Explore the distributed system challenges that Kubernetes addresses Dive into containerized application development, using containers such as Docker Create and run containers on Kubernetes, using the docker image format and container runtime Explore specialized objects essential for running applications in production Reliably roll out new software versions without downtime or errors Get examples of how to develop and deploy real-world applications in Kubernetes

Manage developer-defined infrastructure using the universal Kubernetes solution-TectonicAbout This Book* Deploy, manage, and secure your containers and understand how you can transform your business between the cloud and the datacenter* Deliver consistent environments and save time, money, and resources using the best of CoreOS and Kubernetes through Tectonic* Build next generation Kubernetes-based infrastructure and run powerful enterprise applications on the cloud with simplicityWho This Book Is ForThis book is for developers who want to write Kubernetes-native applications and operators who want to administer distributed systems applications while leveraging best practices.You need a working knowledge of the Linux command line and the basics of Docker and containers, and experience creating at least one local container and a consumed cloud service.What You Will Learn* Deploy code on a container-native stack with flexible architectures and automatic load-balancing for services* Migrate existing workloads to containers or start a new project with containers* Explore CoreOS's packaging of Google Infrastructure For Everyone Else (GIFEE) under the offering name "Tectonic"* "Security Spotlight" which will expand on CoreOS's security-minded approach to each of its projects* Find out how to make informed decisions about which components and edition make sense for your use case* Get insights into the evolving patterns used in microservices in a container infrastructure* Comprehend the components and projects used to run web-scale infrastructure* Best practices and trade-offs to consider when designing cloud-native software and running the infrastructureIn DetailTectonic is a powerful container and enterprise solution by CoreOS. It helps deploy, manage, and secure your containers by leveraging and combining the best features of CoreOS and Kubernetes. It provides an integrated container-based solution and is an initiative toward opinionated infrastructure.The book starts by recognizing that the way infrastructure is defined and consumed is significantly shifting; that we are entering the age of developer-defined infrastructure where the choices of developers dictate what systems, clouds, software, tools, and so on, are used. We then provide a high-level overview of the components and deployment of Tectonic. Next, we cover each component individually at a deeper level with a great emphasis on Kubernetes-the central framework, which is the largest and most complex component within the software suite. Finally, we'll compare it with the other available container orchestration systems, and provide container management best practices, microservices patterns, and anti-patterns in the Kubernetes world.
