Containerization is an approach to software development in which an application or service, its dependencies, and its configuration abstracted as deployment manifest files are packaged together as a container image. You then can test the containerized application as a unit and deploy it as a container image instance to the host operating system OS. Just as shipping containers allow goods to be transported by ship, train, or truck regardless of the cargo inside, software containers act as a standard unit of software deployment that can contain different code and dependencies. Containerizing software this way enables developers and IT professionals to deploy them across environments with little or no modification. Containers also isolate applications from each other on a shared OS. Containerized applications run on top of a container host that in turn runs on the OS Linux or Windows.

AD Teaching Wiki : DockerExample Last updated at This page describes a very simple project with a Dockerfile and a Makefile as required for all projects and theses supervised in our group. The basic idea is really easy: if you were afraid of Docker before, you won't be anymore after reading this page. We also provide a more extensive reproducibility example on Github. This could be overwhelming at first, so we recommend that you read this page first, if you are new to the Docker-world.
