Connections Demo

A demo app showing a simple service using flask and some supporting packages

Requirements

Stack Information

  • Python / Flask
  • MySQL and SQLAlchemy
  • Gunicorn

Getting Started

It is recommended that you run two terminal tabs/windows, one for running the services and the other for running tests.

Building and Running

To build and run the services, run this:

docker-compose up

The application will automatically restart with any changes you make to the source files. The API is available at http://localhost:5005 for you to test manually.

Once the services are up, the database is empty. Run this to migrate the database:

docker-compose exec connections flask db upgrade

Running Tests

The following will run all tests. None should be failing as part of the submission.

docker-compose exec connections pytest

Optionally, you can run a specific test by matching keywords

docker-compose exec connections pytest -k test_create_person

Adding the -s option will run tests without swallowing print statements and may be useful for debugging:

docker-compose exec connections pytest -s

Cleaning up

When you are complete, you can Control-C on the window running the services to stop them. This command will cleanup any volumes created (also allows starting fresh if something is not working):

docker-compose down -v
