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.

What Kubernetes is not

Kubernetes is not a platform as a service (PaaS). It doesn't dictate many of the important aspects of your desired system; instead, it leaves them up to you or to other systems built on top of Kubernetes, such as Deis, OpenShift, and Eldarion. For example:

  • Kubernetes doesn't require a specific application type or framework
  • Kubernetes doesn't require a specific programming language
  • Kubernetes doesn't provide databases or message queues
  • Kubernetes doesn't distinguish apps from services
  • Kubernetes doesn't have a click-to-deploy service marketplace
  • Kubernetes allows users to choose their own logging, monitoring, and alerting systems
