CD is a process based on CI. As part of the CD process, we need other steps that are required to deploy the application to a production environment including tasks such as configuring and provisioning servers (infrastructure as code), acceptance testing, and preparing the build for a production environment.
A continuous deployment process differs from a continuous delivery process when deploying in a production environment without human intervention.
We are now going to create an example based on our simple pipeline. To focus on the processes of CI and CD, we are going to use the project that we created in the last chapter's Docker Compose section that showed you how to containerize your application. This project includes a complete environment that is ready to use, and which already includes an automated test.
