IPython kernel provides a way to run shell commands in code blocks https://jakevdp.github.io/PythonDataScienceHandbook/01.05-ipython-and-shell-commands.html#Shell-Commands-in-IPython

!echo "Hello"

I run the jupyter notebook as docker run --rm -it -p 8888:8888 -p 4040:4040 -p 9001:9001 -e JUPYTER_ENABLE_LAB=yes -v ${PWD}:/home/jovyan/work pavolloffay/trace-dsl:latest. The
command is run in a directory with a library so it is injected into the container. Then I do changes to the library in local IDE running on the host and to load the changes in the notebook I have to run maven install.
