One challenge for a network engineer learning the ‘tools of the trade’ for programmable networks is how to set up a development environment. The environment must be ephemeral, consistent, and repeatable with the instructor, your teammates and your study partner. In this session, we demonstrate how to use Visual Studio Code along with Vagrant, Docker and cloud compute environments. We will share sample configurations in GitLab and also a number of Jupyter Notebooks which can be used as study aides for the Cisco DevNet Certification exams.

Development Containers in Education: A Guide for Instructors
July 27, 2020 by Brigit Murtaugh, @BrigitMurtaugh
We've heard from many educators that the first days or weeks
of the semester can be lost to configuring the correct
environment for students. Even so, students may still end up
with a low-quality development experience or insufficient
grading of their assignments:
"Set up for my students normally takes five class periods.
There are version of Python to deal with. There's a lot of
complexity. Sadly that complexity takes a lot of time and money
to sort out." -[Community College US Professor CS 101]

The goal is to eliminate the Works on My Machine issue due to inconsistencies in environments.
