Building a Foundation with Core Kubernetes Constructs

This chapter will cover the core Kubernetes constructs, namely pods, services, replication controllers, replica sets, and labels. We will describe Kubernetes components, dimensions of the API, and Kubernetes objects. We will also dig into the major Kubernetes cluster components. A few simple application examples will be included to demonstrate each construct. This chapter will also cover basic operations for your cluster. Finally, health checks and scheduling will be introduced with a few examples.

The following topics will be covered in this chapter:

Kubernetes' overall architecture
The context of Kubernetes architecture within system theory
Introduction to core Kubernetes constructs, architecture, and components
How labels can simplify the management of a Kubernetes cluster
Monitoring services and container health
Setting...

Key benefits

Get to grips with a wide range of tools to monitor and secure your deployments

Manage your container clusters and networks using Kubernetes

Get well-versed with the fundamentals of Kubernetes

Description

Kubernetes has continued to grow and achieve broad adoption across various industries, helping you to orchestrate and automate container deployments on a massive scale. Based on the recent release of Kubernetes 1.12, Getting Started with Kubernetes gives you a complete understanding of how to install a Kubernetes cluster. The book focuses on core Kubernetes constructs, such as pods, services, replica sets, replication controllers, and labels. You will understand cluster-level networking in Kubernetes, and learn to set up external access to applications running in the cluster. As you make your way through the book, you'll understand how to manage deployments and perform updates with minimal downtime. In addition to this, you will explore operational aspects of Kubernetes , such as monitoring and logging, later moving on to advanced concepts such as container security and cluster federation. You'll get to grips with integrating your build pipeline and deployments within a Kubernetes cluster, and be able to understand and interact with open source projects. In the concluding chapters, you'll orchestrate updates behind the scenes, avoid downtime on your cluster, and deal with underlying cloud provider instability within your cluster. By the end of this book, you'll have a complete understanding of the Kubernetes platform and will start deploying applications on it.
