Docker is used by Data to Science (D2S) to deploy each application that makes up the D2S platform in an isolated environment known as a container. The version of D2S we will be working with today uses eight containers. Today, we will be building two of these containers locally and using remote repositories for the remaining containers. A deeper dive into Docker containers can be found here.
