Overview of this book

Kubernetes is the most popular container orchestration tool in the industry. The Kubernetes Administrator certification will help you establish your credibility and enable you to efficiently support the business growth of individual organizations with the help of this open source platform. The book begins by introducing you to Kubernetes architecture and the core concepts of Kubernetes. You'll then get to grips with the main Kubernetes API primitives, before diving into cluster installation, configuration, and management. Moving ahead, you’ll explore different approaches while maintaining the Kubernetes cluster, perform upgrades for the Kubernetes cluster, as well as backup and restore etcd. As you advance, you'll deploy and manage workloads on Kubernetes and work with storage for Kubernetes stateful workloads with the help of practical scenarios. You'll also delve into managing the security of Kubernetes applications and understand how different components in Kubernetes communicate with each other and with other applications. The concluding chapters will show you how to troubleshoot cluster- and application-level logging and monitoring, cluster components, and applications in Kubernetes.

FAQs

  • Where should I start to test the Kubernetes cluster?

You can start on your local laptop or desktop on Windows, Linux, or Mac OS, and we recommend using VMware player or Hyper-V to spin up multiple VMs so you can test out a multinode scenario. Using Multipass from Canonical is also great for creating Ubuntu VMs and it supports Linux, Mac, and Windows. Check it out here: https://multipass.run/.

Another option is to get a cloud subscription such as Microsoft Azure, AWS, or GCP, using which you can provision a VM with a click-through experience.

  • Where can I find the latest Kubernetes release to test out?

The Kubernetes GitHub repository is where you can find all the releases as well as changelogs, and you can get the latest release and build it by yourself: https://github.com/kubernetes/kubernetes.

We can also use kubeadm or minikube to get Kubernetes, as they are aligned with the Kubernetes source code delivery cycle and are up to date.
