Experiment 1

Write code for a simple user registration form for an event.

Files

• app.py: The main Flask application file that contains the routes and logic for the user registration form.
• Dockerfile: The Dockerfile used to build the Docker image for the Flask application.
• Dockerfile.test: The Dockerfile used to build the Docker image for running unit tests on the Flask application.
• requirements.txt: A file listing the Python dependencies required to run the Flask application.
• templates/: A directory containing HTML templates for the Flask application.
  • register.html: The HTML template for the user registration form.
  • success.html: The HTML template displayed after a successful user registration.

Build

To build the Docker image for the Flask application, run the following command:

docker build --no-cache -t simple-flask-app .

Run

To run the Docker container for the Flask application, use the following command:

docker run -p 80:80 simple-flask-app

After running the container, open your web browser and navigate to http://0.0.0.0:80/register to access the user registration form.

Testing

To run the unit tests for app.py using Docker, follow these steps:

1. Build the Docker image for testing:

docker build -f Dockerfile.test -t simple-flask-app-test .

2. Run the Docker container to execute the tests:

docker run simple-flask-app-test

This command will discover and run all the unit tests in the test_app.py file.
