If you have Docker installed locally, you have three options to build and run the Flask application inside a container.

IMPORTANT: This section is for illustrative purposes only and you do not need to run these commands.

Clone the Visual Studio Code Flask tutorial:

git clone https://github.com/Microsoft/python-sample-vscode-flask-tutorial
cd python-sample-vscode-flask-tutorial/

Run the application from inside of a Docker container:

docker run --rm -v ${PWD}:/pwd/ -w /pwd/ -p 8080:5000 -it python bash
pip install -r requirements.txt
export FLASK_APP=startup.py
flask run --host=0.0.0.0
# open http://localhost:8080

Build a development container from a Dockerfile (dev.Dockerfile).

docker build -f dev.Dockerfile -t test python-sample-vscode-flask-tutorial/
docker run --rm -p 8080:5000 -it test
# open http://localhost:8080

Build a production container from a Dockerfile (prod.Dockerfile).

docker build -f prod.Dockerfile -t prod python-sample-vscode-flask-tutorial/
docker run --rm -p 8080:5000 -it prod
# open http://localhost:8080
