A developer's field-guide to designing scalable services using Kubernetes

About This Book

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

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.

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

In Detail

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.

Style and approach

This book will cover examples using NodeJS and Python that walk you through building containers, defining your deployments, deploying, debugging, testing, and generally interacting with your code running on Kubernetes. The examples are focused on common development needs, and include pragmatic advice and the explanations behind that advice.
