• APPLICATION_CONFIG is strictly related to my project and is used only to load a JSON configuration file with the name specified in the variable itself.

• FLASK_CONFIG is used to select the Python object that contains the configuration for the Flask application (see application/app.py and application/config.py). The value of the variable is converted into the name of a class.

• FLASK_ENV is a variable used by Flask itself, and its values are dictated by it. See the configuration documentation mentioned in the resources of the previous section.

• Config database: SQLALCHEMY_DATABASE_URI = ( f"postgresql+psycopg2://ogwsmojrynkhmc:5e3f5b888472b53141e050ea3e366765203feab53b43a13248b65f718e477e63@ec2-52-86-2-228.compute-1.amazonaws.com:5432/dg0q8kfl0thi4" )

1. Give permission to manage.py

• chmod 775 manage.py

2. Create venv

• sudo apt-get install python3-venv
• sudo apt-get install python3-tk
• python3 -m venv .venv
• source .venv/bin/activate
• pip3 install -r requirements/development.txt
• python3 -m pip install
• pip3 freeze > requirements.txt

2. Init database

• ./manage.py flask db init
• ./manage.py flask db stamp head
• ./manage.py flask db migrate
• ./manage.py flask db upgrade

3. Update database

• ./manage.py flask db stamp head
• ./manage.py flask db migrate
• ./manage.py flask db upgrade

4. Run flask with config

• Run by flask command line: FLASK_CONFIG="development" flask run
• Run with manage.py: ./manage.py flask run

5. Build the image

• FLASK_ENV="development" FLASK_CONFIG="development" docker-compose -f docker/development.yml build web
• If you need to explore the container you can login directly with

docker exec -it docker_web_1 bash

or with

FLASK_ENV="development" FLASK_CONFIG="development" docker-compose -f docker/development.yml exec web bash

• To tear down the containers, when running as daemon, you can run

FLASK_ENV="development" FLASK_CONFIG="development" docker-compose -f docker/development.yml down

• If you need to explore the container you can login directly with

$ docker exec -it docker_web_1 bash

or with

$ FLASK_ENV="development" FLASK_CONFIG="development" docker-compose -f docker/development.yml exec web bash

• Run ./manage.py compose up -d and ./manage.py compose down and have the environment variables automatically passed to the system

• python3 -m pip install flask_jwt_extended
• python3 -m pip install flask_mail
• python3 -m pip install marshmallow
• python3 -m pip install webargs

• Run pytest

• Need to install: sudo apt-get install libpq-dev before installing the 'psycopg2' library
• Permission Denied for docker-compose: try with sudo
