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.

  • Itemized billing

    Warning

    GKE and other hosted Kubernetes services are not free. Some services might provide a free tier or an initial amount of free credit. However, generally speaking, you have to pay to use them.

Configuring GKE

To work with GKE, you'll need an account on the Google Cloud with billing configured and a blank project. These are all simple to set up, so we won't spend time explaining them here – for the remainder of this section, we'll be assuming you have these.

The following steps will walk you through configuring GKE via a web browser. Some of the details might change in the future, but the overall flow will be the same:
