Overview of this book

Kubernetes is the leading orchestrator of cloud-native apps. With knowledge of how to work with Kubernetes, you can easily deploy and manage applications on the cloud or in your on-premises data center. The book begins by introducing you to Kubernetes and showing you how to install it. You’ll learn how to use Kubernetes Services and bring stable and reliable networking to apps that are deployed on Kubernetes. You'll delve deep into the powerful storage subsystem of Kubernetes and learn how to leverage the variety of external storage backends in your applications. As the book progresses, it shows you how to use features such as DaemonSets, Helm, and RBAC to enhance your Kubernetes applications. You'll explore the six categories of identifying vulnerabilities and look at a few ways to prevent and mitigate them. You'll also look at ways to secure the software delivery pipeline by discussing some image-related best practices. The book ends by sharing with you some resources that’ll help take your Kubernetes knowledge to the next level. By the end of the book, you’ll have the confidence and skills to leverage all the features of Kubernetes to develop scalable applications.

Where did Kubernetes Come From?

Let's start from the beginning.

Kubernetes was released by Google. It is the product of Google's many years orchestrating containers at an extreme scale. It was open sourced in the summer of 2014 and handed over to the Cloud Native Computing Foundation (CNCF).

Since then, it's become the most important cloud-native technology on the planet.

Like many modern cloud-native projects, it's written in Go (Golang), it lives on GitHub at kubernetes/kubernetes, it's actively discussed on the IRC channels, you can follow it on Twitter (@kubernetesio), and slack.k8s.io is a pretty good slack channel. There are also regular meetups and conferences all over the planet.

Kubernetes and Docker

Kubernetes and Docker are complementary technologies. For example, it's common to develop your applications with Docker and use Kubernetes to orchestrate them.

In this model, you write...
