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.

Jenkins

If you committed your work to Jenkins, you may have noticed the Jenkins build broke somewhere. We fixed most of it; we fixed our Gulp build after all. However, some issues remain. The build project fails because of some SonarQube issues. You can do three things, fix your code (you would have to remove some alert() and console.log() statements), disable the rules in SonarQube, or configure your Jenkins project, so it will not fail because of SonarQube. That last option is the quickest; simply remove the Quality Gates post-build action. In production code, we would not use alert() and console.log(), but for now, I do not find that a problem.

With the build project running again, we should publish the extra reports we are generating for our Node.js tests. We have an extra Cobertura report, so the XML report pattern should now be test/coverage/cobertura/*.xml,coverage/*.xml...
