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.

Storage Providers

Kubernetes can use storage from a wide range of external systems. These will often be native cloud services such as AWSElasticBlockStore or AzureDisk, but they can also be traditional on-premises storage arrays providing iSCSI or NFS volumes. Other options exist, but the take-home point is that Kubernetes gets its storage from a wide range of external systems.

Some obvious restrictions apply. For example, you cannot use the AWSElasticBlockStore provisioner if your Kubernetes cluster is running in Microsoft Azure.
