• Create a virtualenv: python3 -m venv .venv (only need to run once).
• Activate the virtualenv: . .venv/bin/activate
• Install requirements within virtualenv: pip3 install -r requirements.txt (only when requirements change)
• Deactivate virtualenv (when done using it): deactivate

Run flask app:

export FLASK_APP=src.main
export FLASK_DEBUG=1  # hot-reloads application when code changes 
flask run

Visit http://localhost:5000 to view the app.

Within virtualenv: black src --check

Within virtualenv: python -m pytest

Build the repo and tag the resulting image with "web-app-demo:latest":

docker build . -t web-app-demo

Run the image in a container named "web-app-demo-container", and forward the container port 5000 to the host port 5000:

docker run -p 5000:5000 --name web-app-demo-container web-app-demo

docker run web-app-demo black src --check

If the container is already running (with container name "web-app-demo-container"), lint can also be executed with docker exec:

docker exec web-app-demo-container black src --check

docker run web-app-demo python -m pytest

If the container is already running (with container name "web-app-demo-container"), unit tests can also be executed with docker exec:

docker exec web-app-demo-container python -m pytest
