Kubernetes for Developers

By: Joseph Heck

Overview of this book

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.

Chapter 9. Integration Testing

So far, we have reviewed how to run your code and describe your services in Kubernetes. We also looked into how to utilize additional tools to get information about how your code is running on each pod and on aggregate. This chapter builds on this to look at how to use Kubernetes to validate your code, with examples of different ways to accomplish that testing, and suggestions for how to leverage Kubernetes for validation testing.

Topics for this chapter include:

  • Testing strategies using Kubernetes
  • Simple validation with Bats
  • Example – testing code with Python
  • Example – testing code with Node.js
  • Continuous integration with Kubernetes
