Before actually implementing continuous delivery for our project, let's start by making some preparations. Later, these will make it easier for the tools that we will use to easily build and deploy your application in an automated way.
Before automatically building your application, you will need a place to store your application's source code. This is typically the job of a version control system (VCS). Often, the tools that enable you to do continuous delivery are tightly integrated with version control systems, for example, by triggering a new build and deployment of your application whenever the source code is changed.
If you did not do this already on your own, your first step should now be to put your existing code base into a VCS. In this example, we will be working with the current de facto standard VCS, Git. Although there are many other version control systems, Git is the most widely adopted; you will find many providers and tools...
