You don't need to teach docker. All you need is providing a docker image with everything pre-installed such as Julia, R language, Python, numpy, pandas, Tensorflow and maybe Vscode. And also any Linux distribution, then one can just type "$ docker --rm -it -v $PWD:/cwd -w /cwd my-image ipython" For better convenience, it is better creating a command line wrapper or shell script that saves one from typing that such as $ ./run-my-image ipython. I don't prepare anyone, but I guess that if I knew anything about docker and was given a docker image with everything ready and pre-configured and also a shell script or command line encapsulating all docker command line switches, I would find it more convenient than installing everything myself or fighting some dependency conflict or dependency hell. So, docker can be used as a portable environment development. VScode, aka visual studio code, also supports remote development within docker containers with extensions installed per container. I am a mechanical engineer by training, but I found docker pretty convenient for getting Julia, Octave, R language, Python, Jupyter Notebook server without installing anything or fighting with package manager of my Linux distribution when attempting to install a different version of R, Julia or Python. This approach makes easier for getting bleeding edge development tools without breaking anything that is already installed. I even created a command line wrapper tool for using docker in this way that simplifies all those case: $ mytool bash jupyter-image; $ mytool daemon jupyter-notebook ...
