Continuous Integration, Delivery, and Deployment

By: Sander Rossel

Overview of this book

The challenge faced by many teams while implementing Continuous Deployment is that it requires the use of many tools and processes that all work together. Learning and implementing all these tools (correctly) takes a lot of time and effort, leading people to wonder whether it's really worth it. This book sets up a project to show you the different steps, processes, and tools in Continuous Deployment and the actual problems they solve. We start by introducing Continuous Integration (CI), deployment, and delivery as well as providing an overview of the tools used in CI. You'll then create a web app and see how Git can be used in a CI environment. Moving on, you'll explore unit testing using Jasmine and browser testing using Karma and Selenium for your app. You'll also find out how to automate tasks using Gulp and Jenkins. Next, you'll get acquainted with database integration for different platforms, such as MongoDB and PostgreSQL. Finally, you'll set up different Jenkins jobs to integrate with Node.js and C# projects, and Jenkins pipelines to make branching easier. By the end of the book, you'll have implemented Continuous Delivery and deployment from scratch.

Installing SonarQube

SonarQube (https://www.sonarqube.org/) is a tool that scans your code and does a quality check. A set of rules are applied to your code and every time you break a rule, SonarQube will report it and add it to the technical debt. A rule can be simple, such as a missing semi-colon at the end of a JavaScript line. That should be a few seconds fix. Another rule can be more difficult, such as that the complexity of a function (nested loop and if statements and the lines of code add to the complexity) should not be greater than a certain value. SonarQube has a default set of rules, but you can roll out your own. In this book, we are going to see SonarQube with HTML, CSS, JavaScript, and C#, but SonarQube supports many languages, such as Java, VB.NET, SQL, Haskell, PHP, and many more.
