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.

The process

There is a lot to do. Here is a list of some of the concerns you'll have to address:

  • Implementing your own cloud provider's interface or sidestepping it
  • Choosing a networking model and how to implement it (using a CNI plugin or directly compiling)
  • Whether or not to use a network policy
  • Select images for system components
  • Security models and SSL certificates
  • Admin credentials
  • Templates for components such as an API server, replication controller, and scheduler
  • Cluster services such as DNS, logging, monitoring, and GUI

I recommend reading the guide at the Kubernetes site ( to get a deeper understanding of what it takes to create a cluster from scratch.
