Building Enterprise JavaScript Applications

By: Daniel Li

Overview of this book

With the over-abundance of tools in the JavaScript ecosystem, it's easy to feel lost. Build tools, package managers, loaders, bundlers, linters, compilers, transpilers, typecheckers - how do you make sense of it all? In this book, we will build a simple API and React application from scratch. We begin by setting up our development environment using Git, yarn, Babel, and ESLint. Then, we will use Express, Elasticsearch and JSON Web Tokens (JWTs) to build a stateless API service. For the front-end, we will use React, Redux, and Webpack. A central theme in the book is maintaining code quality. As such, we will enforce a Test-Driven Development (TDD) process using Selenium, Cucumber, Mocha, Sinon, and Istanbul. As we progress through the book, the focus will shift towards automation and infrastructure. You will learn to work with Continuous Integration (CI) servers like Jenkins, deploying services inside Docker containers, and run them on Kubernetes. By following this book, you would gain the skills needed to build robust, production-ready applications.

Visualizing Kubernetes Objects using the Web UI Dashboard

You've been introduced to a lot of Kubernetes in this chapter—Namespaces, Nodes, Pods, Deployments, ReplicaSet, StatefulSet, DaemonSet, Services, Volumes, PersistentVolumes, and StorageClasses. So, let's take a mini-breather before we continue.

So far, we've been using kubectl for everything. While kubectl is great, sometimes, visual tools can help. The Kubernetes project provides a convenient Web UI Dashboard that allows you to visualize all Kubernetes Objects easily.


The Kubernetes Web UI Dashboard is different from the DigitalOcean Dashboard.

Both kubectl and the Web UI Dashboard make calls to the kube-apiserver, but the former is a command-line tool, whereas the latter provides a web interface.

By default, the Web UI Dashboard is not deployed automatically. We'd normally need to run the following to get an instance of the Dashboard running on our cluster:

$ kubectl create -f
