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.

Multibranch pipeline

The Multibranch pipeline is the next step from the regular pipeline. It is pretty much the same, except it can run your script on every branch that has it. Any new branches are automatically scanned and build. Add a new item in Jenkins and pick the Multibranch Pipeline project type. The configuration requires you to specify your Git repository, but this time, you cannot specify a specific branch. The build configuration mode is set to by Jenkinsfile which, in this case, means your Jenkinsfile from source control. We can leave all the other settings for now. Save your configuration and you will be taken to the Scan Multibranch Pipeline Log. You should see Jenkins checking your repository for branches and Jenkinsfiles:

Getting remote branches...
Seen branch in repository origin/master
Seen 1 remote branch
Checking branch master
‘Jenkinsfile’...
