Overview of this book

Containerization is said to be the best way to implement DevOps. Google developed Kubernetes, which orchestrates containers efficiently and is considered the frontrunner in container orchestration. Kubernetes is an orchestrator that creates and manages your containers on clusters of servers. This book will guide you from simply deploying a container to administrate a Kubernetes cluster, and then you will learn how to do monitoring, logging, and continuous deployment in DevOps. The initial stages of the book will introduce the fundamental DevOps and the concept of containers. It will move on to how to containerize applications and deploy them into. The book will then introduce networks in Kubernetes. We then move on to advanced DevOps skills such as monitoring, logging, and continuous deployment in Kubernetes. It will proceed to introduce permission control for Kubernetes resources via attribute-based access control and role-based access control. The final stage of the book will cover deploying and managing your container clusters on the popular public cloud Amazon Web Services and Google Cloud Platform. At the end of the book, other orchestration frameworks, such as Docker Swarm mode, Amazon ECS, and Apache Mesos will be discussed.

Kubernetes resource management

Chapter 3, Getting Started with Kubernetes mentioned that Kubernetes has a scheduler that manages Kubernetes node and then determines where to deploy a pod. When node has enough resources such as CPU and memory, Kubernetes administrator can feel free to deploy an application. However, once it reaches its resource limit, the Kubernetes scheduler behaves different based on its configuration. Therefore, the Kubernetes administrator has to understand how to configure and utilize machine resources.

Resource Quality of Service

Kubernetes has the concept of Resource QoS (Quality of Service), which helps an administrator to assign and manage pods by different priorities. Based on the pod's setting...
