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.

Play with Kubernetes

Play with Kubernetes (PWK) is free and is a great way to get your hands on a Kubernetes cluster without having to install anything. All you need is a computer, an internet connection, and an account on Docker Hub or GitHub. In my opinion, it's the fastest and easiest way to get your hands on Kubernetes.

However, it has limitations. For starters, it's a time-limited playground – you get a lab that lasts for 4 hours. It also lacks some integrations with external services such as cloud-based load-balancers. However, limitations aside, it's a great tool and I use it all the time.

Let's see what it looks like:

  1. Point your browser at http://play-with-k8s.com.
  2. Log in with your GitHub or Docker Hub account and click Start.
  3. Click + ADD NEW INSTANCE from the navigation pane on the left of your browser.

    You will be presented with a Terminal window on the right of your browser. This is a Kubernetes node (node1).

  4. Run a few...
