We can use Docker to set up a stable and repeatable environment where our firmware is built and unit tested. Furthermore, we can use access the hardware from the container to perform integration testing. A shared directory will allow us to access our code from within the containerized environment.

from https://dev.to/djangostars/what-is-docker-and-how-to-use-it-with-python-tutorial-87a:

• 1 application = 1 container.
• Run the process in the foreground (don't use systemd, upstart or any other similar tools).
• Keep data out of containers – use volumes.
• Do not use SSH (if you need to step into container, you can use the docker exec command).
• Avoid manual configurations (or actions) inside container.
