A Gradle book will be incomplete, unless we talk about the deployment aspect of a software component. In my opinion, in software engineering the most logical step after build automation is deployment. Deployment itself is a different domain and this has very little to do with Gradle. But still I think it makes sense to discuss build and deployment tools together, so that the reader gets an overview of Build, Deploy, and Test workflow. In this chapter, we will discuss some basics of deployment to give a flavor of the build and deployment process. We will learn how to use tools such as Gradle, Jenkins, and Docker together to create a build, deployment, and test workflow. Before we start, we have to understand, what deployment is. Deployment is as important as the build process in the software life cycle. You can write and build great software, but unless the application is deployed, it does not produce much value.
