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 8. Logging and Tracing

When we first started with containers and Kubernetes, we showed how we could get the log output from any of our individual containers using the kubectl log command. As we scale the number of containers from which we want to get information, the ability to easily find the relevant logs becomes increasingly difficult. In the previous chapter, we looked at how to aggregate and collect metrics, and in this chapter we extend that same concept, looking at how to aggregate logging and getting a better understanding of how containers work together with distributed tracing.

Topics for this chapter include:

  • A Kubernetes concept—DaemonSet
  • Installing Elasticsearch, Fluentd, and Kibana
  • Viewing logs using Kibana
  • Distributed tracing with Jeager
  • An example of adding tracing to your application
