In this example, we study in depth how to create a machine learning container which can be run on the cluster. In principle, this works just like creating any other docker container. However, from - the very beginning, we should write our code so that it fits a few special conventions, in particular about where you read/write your main difficulty will be how to store data. While it is in principle possible to map the directories on the cluster node to any directory which is used by your program, it is advised that you stick to a certain structure, in particular if you intend your code to be easily parsed by other peoplepersistent manner. We will start simple, and then gradually add more capability for our program.
