R

2020
When I began learning about how to use Docker I stumbled on an excellent project called Rocker. For anyone with an x86 machine these Rocker images allow them to run R and most of its dependencies in a containerised environment. Plumber APIs, anyone? What about your own Shiny server? Finally, data scientists using R can have the same level of control on dependencies and package versions as Python users have become accustomed to through venv.
