Getting Started with Kubernetes - Third Edition

By: Jonathan Baier, Jesse White

Overview of this book

Kubernetes has continued to grow and achieve broad adoption across various industries, helping you to orchestrate and automate container deployments on a massive scale. Based on the recent release of Kubernetes 1.12, Getting Started with Kubernetes gives you a complete understanding of how to install a Kubernetes cluster. The book focuses on core Kubernetes constructs, such as pods, services, replica sets, replication controllers, and labels. You will understand cluster-level networking in Kubernetes, and learn to set up external access to applications running in the cluster. As you make your way through the book, you'll understand how to manage deployments and perform updates with minimal downtime. In addition to this, you will explore operational aspects of Kubernetes , such as monitoring and logging, later moving on to advanced concepts such as container security and cluster federation. You'll get to grips with integrating your build pipeline and deployments within a Kubernetes cluster, and be able to understand and interact with open source projects. In the concluding chapters, you'll orchestrate updates behind the scenes, avoid downtime on your cluster, and deal with underlying cloud provider instability within your cluster. By the end of this book, you'll have a complete understanding of the Kubernetes platform and will start deploying applications on it.

gulp.js


gulp.js gives us the framework to do build as code. Similar to Infrastructure as code, this allows us to programmatically define our build process. We will walk through a short example to demonstrate how you can create a complete workflow, from a Docker image build through to the final Kubernetes service.

Prerequisites

For this section of the article, you will need a Node.js environment installed and ready, including the node package manager (npm). If you do not already have these packages installed, you can find instructions for installing them at https://docs.npmjs.com/getting-started/installing-node.

You can check whether or not Node.js is installed correctly by using the node -v command.

You'll also need Docker CE and a Docker Hub account to push a new image. You can find instructions to install Docker CE at https://docs.docker.com/installation/. You can easily create a DockerHub account at https://hub.docker.com/.
