Hands-On Continuous Integration and Delivery

By: Jean-Marcel Belmont

Overview of this book

Hands-On Continuous Integration and Delivery starts with the fundamentals of continuous integration (CI) and continuous delivery (CD) and where it fits in the DevOps ecosystem. You will explore the importance of stakeholder collaboration as part of CI/CD. As you make your way through the chapters, you will get to grips with Jenkins UI, and learn to install Jenkins on different platforms, add plugins, and write freestyle scripts. Next, you will gain hands-on experience of developing plugins with Jenkins UI, building the Jenkins 2.0 pipeline, and performing Docker integration. In the concluding chapters, you will install Travis CI and Circle CI and carry out scripting, logging, and debugging, helping you to acquire a broad knowledge of CI/CD with Travis CI and CircleCI. By the end of this book, you will have a detailed understanding of best practices for CI/CD systems and be able to implement them with confidence.

CircleCI

CircleCI is a hosted and automated solution for continuous integration (CI) builds. CircleCI uses an in application configuration file that uses YAML ( http://yaml.org/spec/1.2/spec.html) syntax, such as Travis YML script, which we discussed in Chapter 9, Installation and Basics of Travis CI, to Chapter 11, Travis CI UI Logging and Debugging. Since CircleCI is hosted in the cloud, it has the advantage that it can be set up quickly in other environments as well as used in different operating systems without having to worry about setup and installation like you have to do with Jenkins CI. Because of this, CircleCI is much faster to set up than Jenkins.
