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.

Promoted builds

Another very cool plugin is the Promoted Builds plugin (https://wiki.jenkins.io/display/JENKINS/Promoted+Builds+Plugin). This plugin solves some of the problems we had earlier. It also makes the Join plugin obsolete. The idea behind promoted builds is that a build can be promoted based on various criteria (including promotion of other projects). Upon promotion, one or more additional build steps can be executed (including triggered another project). Whenever a build is promoted, it gets a promotion symbol on the build list. So, install the Promoted Builds plugin from the plugin manager.

We just used the Join plugin to wait for our database tests, browser tests, and E2E tests before triggering the deployment project. Instead, we can now use a promotion. Go to the CSharp Web Shop - Build project configuration and find the Promote builds when... checkbox in the General...
