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. This book will give you a complete understanding of Kubernetes and how to get a cluster up and running. You will develop an understanding of the installation and configuration process. The book will then focus on the core Kubernetes constructs such as pods, services, replica sets, replication controllers, and labels. You will also understand how cluster level networking is done in Kubernetes. The book will also show you how to manage deployments and perform updates with minimal downtime. Additionally, you will learn about operational aspects of Kubernetes such as monitoring and logging. Advanced concepts such as container security and cluster federation will also be covered. Finally, you will learn about the wider Kubernetes ecosystem with OCP, CoreOS, and Tectonic and explore the third-party extensions and tools that can be used with Kubernetes. By the end of the book, you will have a complete understanding of the Kubernetes platform and will start deploying applications on it.

Preface

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 to the final Kubernetes service.

Prerequisites

For this section of the article, you will need a NodeJS 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 NodeJS is installed correctly with a node -v command.

You'll also need Docker CE and a DockerHub 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/.

After you have your credentials, you can log in with the CLI using $ docker login command.
