I created a Dockerfile for this course to run the flask application, jupyter notebook, the mongo-shell and the mongo-tools on Docker. You can find it here M220P Dockerfile.
Note: I didnt create a docker container on the docker-hub, but instead just a dockerfile. It should serve merely as a skeleton for this project and be as general as it can be.
Continuing this course i might still update this repository and also add Docker Compose, who knows. But for now it serves my needs.
I hope this helps someone out there
