This document provides an overview of how to convert an existing Sitecore module into a Docker image. It discusses what Docker is, how existing Sitecore modules are installed, and the steps to take a module and prepare the necessary assets and configuration to build it into a Docker image. This includes extracting content and database resources, using tools like Sitecore Courier to generate a DACPAC, adding a Dockerfile and Docker Compose configuration, and building and publishing the final image.
