Overview of this book

With its broad adoption across various industries, Kubernetes is helping engineers with the orchestration and automation of container deployments on a large scale, making it the leading container orchestration system and the most popular choice for running containerized applications. This Kubernetes book starts with an introduction to Kubernetes and containerization, covering the setup of your local development environment and the roles of the most important Kubernetes components. Along with covering the core concepts necessary to make the most of your infrastructure, this book will also help you get acquainted with the fundamentals of Kubernetes. As you advance, you'll learn how to manage Kubernetes clusters on cloud platforms, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), and develop and deploy real-world applications in Kubernetes using practical examples. Additionally, you'll get to grips with managing microservices along with best practices. By the end of this book, you'll be equipped with battle-tested knowledge of advanced Kubernetes topics, such as scheduling of Pods and managing incoming traffic to the cluster, and be ready to work with Kubernetes on cloud platforms.

Deploying a workload and interacting with your cluster

One of the things to note from the feedback when we launched our cluster is the following output:

kubeconfig entry generated for k8sforbeginners.

As you may have already guessed, this has downloaded and configured all of the necessary information to connect the kubectl instance that you used to launch the cluster. You can confirm this by running the following command:

$ kubectl get nodes

The output you get from the command should show two nodes with a prefix of gke, so should appear something like the following Terminal output:

Figure 14.9 – Using kubectl to list the nodes

If you saw the preceding output and you are happy to proceed with the kubectl instance you are using, then you can skip the next section of the chapter and move straight onto Launching an example workload.

You can also find a link to the official GKE documentation in the Further reading section at the end of...
