Mastering Kubernetes - Second Edition

By: Gigi Sayfan

Overview of this book

Kubernetes is an open source system that is used to automate the deployment, scaling, and management of containerized applications. If you are running more containers or want automated management of your containers, you need Kubernetes at your disposal. To put things into perspective, Mastering Kubernetes walks you through the advanced management of Kubernetes clusters. To start with, you will learn the fundamentals of both Kubernetes architecture and Kubernetes design in detail. You will discover how to run complex stateful microservices on Kubernetes including advanced features such as horizontal pod autoscaling, rolling updates, resource quotas, and persistent storage backend. Using real-world use cases, you will explore the options for network configuration, and understand how to set up, operate, and troubleshoot various Kubernetes networking plugins. In addition to this, you will get to grips with custom resource development and utilization in automation and maintenance workflows. To scale up your knowledge of Kubernetes, you will encounter some additional concepts based on the Kubernetes 1.10 release, such as Promethus, Role-based access control, API aggregation, and more. By the end of this book, you’ll know everything you need to graduate from intermediate to advanced level of understanding Kubernetes.

Monitoring, Logging, and Troubleshooting

In Chapter 2, Creating Kubernetes Clusters, you learned how to create Kubernetes clusters in different environments, experimented with different tools, and created a couple of clusters.

Creating a Kubernetes cluster is just the beginning of the story. Once the cluster is up and running, you need to make sure that it is operational, all the necessary components are in place and properly configured, and enough resources are deployed to satisfy the requirements. Responding to failures, debugging, and troubleshooting is a major part of managing any complicated system, and Kubernetes is no exception.

The following topics will be covered in this chapter:

  • Monitoring with Heapster
  • Performance analytics with Kubernetes dashboard
  • Central logging
  • Detecting problems at the node level
  • Troubleshooting scenarios
  • Using Prometheus
