Overview of this book

Thanks to its extensive support for managing hundreds of containers that run cloud-native applications, Kubernetes is the most popular open source container orchestration platform that makes cluster management easy. This workshop adopts a practical approach to get you acquainted with the Kubernetes environment and its applications. Starting with an introduction to the fundamentals of Kubernetes, you’ll install and set up your Kubernetes environment. You’ll understand how to write YAML files and deploy your first simple web application container using Pod. You’ll then assign human-friendly names to Pods, explore various Kubernetes entities and functions, and discover when to use them. As you work through the chapters, this Kubernetes book will show you how you can make full-scale use of Kubernetes by applying a variety of techniques for designing components and deploying clusters. You’ll also get to grips with security policies for limiting access to certain functions inside the cluster. Toward the end of the book, you’ll get a rundown of Kubernetes advanced features for building your own controller and upgrading to a Kubernetes cluster without downtime. By the end of this workshop, you’ll be able to manage containers and run cloud-based applications efficiently using Kubernetes.

Every pod has a pod status that tells us what stage of its life cycle a pod is in. We can see the pod status by running the kubectl get command:

kubectl get pod

You will see the following response:

first-pod    1/1         Running       0             5m44s

For our first pod, named first-pod, we see that the pod is in the Running state.

Let's see what the different states that a pod can have in its life cycle are:

  • Pending: This means that the pod has been submitted to the cluster, but the controller hasn't created all its containers yet. It may be downloading images or waiting for the pod to be scheduled on one of the cluster nodes.
  • Running: This state means that the...
