Code forked from https://github.com/brennv/flask-app. Deploy configuration changed for test purposes

Example app for demonstrating continuos integration/continuos deployment (CI/CD) workflows -- inspired by dockercloud-quickstart-python.

The example flask app connects to a redis instance and displays a simple visit counter and the hostname of the docker container serving the app.

Install docker and run:

docker-compose up
# docker-compose stop

Otherwise, for the standalone web service:

pip install -r requirements.txt
python app.py

Visit http://localhost:5000

Create a new branch off the develop branch for features or fixes.

After making changes rebuild images and run the app:

docker-compose build
docker-compose run -p 5000:5000 web python app.py
# docker stop flaskapp_redis_1

Standalone unit tests run with:

pip install pytest pytest-cov pytest-flask
pytest --cov=web/ --ignore=tests/integration tests

Integration and unit tests run with:

docker-compose -f test.yml -p ci build
docker-compose -f test.yml -p ci run test python -m pytest --cov=web/ tests
# docker stop ci_redis_1 ci_web_1

Commits tested via travis-ci.org. Test coverage reported to codecov.io. Requirements inspected with requires.io.

After testing, submit a pull request to merge changes with develop.
