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.

In this chapter, we introduced Prometheus and showed how to install it, used it to capture metrics from your Kubernetes cluster, and showed how to install and use Grafana to provide dashboards, using the metrics captured and temporarily stored in Prometheus. We then looked at how you can expose custom metrics from your own code and leverage Prometheus to capture them, along with a few examples of metrics you might be interested in tracking, such as error rate, response time, and throughput.

In the next chapter, we continue to look into observability for our applications with tools to help us capture logs and traces.
