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.

Distributed tracing with Jaeger

As you decompose your services into multiple containers, one of the hardest things to understand is the flow and path of requests, and how containers are interacting. As you expand and use more containers to support components within your system, knowing which containers are which and how they're contributing to the performance of a request becomes a significant challenge. For simple systems, you can often add logging and get a view through the log files. As you move into dozens, or even hundreds, of different containers making up a service, that process becomes far less tenable.

One solution to this problem is called Distributed Tracing, which is a means of tracking the path of requests between containers, much like a profiler can track requests within a single application. This involves using libraries or frameworks that support a tracing library to create and pass along the information, as well as a system external to your application to collect this information...
