These default values can be changed in the `docker-compose.yml` file. 8 | A table `players` with one record is created by copying the file `db/init/init.sql` into the `/docker-entrypoint-initdb.d/` container directory ([see documentation of postgres official image](https://hub.docker.com/_/postgres/)). 9 | 10 | The Flask application uses SQLAlchemy to retrieve the content of the `players`, ReactJS call the REST API and display it ! 11 | 12 | **Hot reloading** is enabled for the React and Flask code, after every code change the container is up-to-date automatically ! 13 | 14 | ### Run the app 15 | 16 | Everything is containerized from the client, backend to the database. So all you need is Docker installed, and then you can run : 17 | 18 | ``` 19 | docker-compose up --build 20 | ``` 21 | 22 | And your app will be up on the *port 3000* ! 23 | 24 | ### Special notes 25 | 26 | ##### Using Docker Toolbox 27 | 28 | This project was implemented with [Docker Toolbox](https://docs.docker.com/toolbox/toolbox_install_windows/), which need some fixes ([read my article on medium for more information](https://medium.com/@thimblot/using-docker-on-windows-without-hyper-v-troubleshooting-tips-2949587f796a)) before running the `docker-compose up` command. 29 | That's the goal of the `docker-compose-up.sh` file at the root of the project, use it instead of the `docker-compose up` command if you are running Docker with the Toolbox. 30 | 31 | Flask and ReactJS part of the application use the IP adress / port for containers communication (see `config.py` and `config.js`). You can normally use the name of the service located on the docker-compose.yml, but it doesn't seems to work using Docker Toolbox ! 32 | 33 | ##### Reloading Database configuration 34 | 35 | If you change user, password, database name or any other kind of database configuration, you may need to run `docker-compose -up --build` from a fresh start. Make sure to run `docker-compose down` before or even `docker-compose rm` if some containers are stopped but not destroyed. -------------------------------------------------------------------------------- /backend/Dockerfile: -------------------------------------------------------------------------------- 1 | FROM python:3-onbuild 2 | COPY . /usr/src/app 3 | CMD ["python", "app.py"] -------------------------------------------------------------------------------- /backend/api/__init__.py: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/tomahim/react-flask-postgres-boilerplate-with-docker/c4138df028818ca472941f110b6221e67b5b8728/backend/api/__init__.py -------------------------------------------------------------------------------- /backend/api/api.py: -------------------------------------------------------------------------------- 1 | from flask import jsonify 2 | from flask_restful import Resource, Api 3 | 4 | from .models import Player as PlayerModel, to_dict 5 | 6 | api = Api() 7 | 8 | class Player(Resource): 9 | def get(self): 10 | return jsonify([to_dict(player) for player in PlayerModel.query.all()]) 11 | 12 | api.add_resource(Player, '/') 13 | -------------------------------------------------------------------------------- /backend/api/config.py: -------------------------------------------------------------------------------- 1 | class Config(object): 2 | DEBUG = True 3 | TESTING = True 4 | SQLALCHEMY_DATABASE_URI = 'postgresql+psycopg2://myuser:mypassword@192.168.99.100/sport_stats' 5 | SQLALCHEMY_TRACK_MODIFICATIONS = False -------------------------------------------------------------------------------- /backend/api/models.py: -------------------------------------------------------------------------------- 1 | import json 2 | 3 | from flask_sqlalchemy import SQLAlchemy 4 | from sqlalchemy.ext.declarative import DeclarativeMeta 5 | 6 | db = SQLAlchemy() 7 | 8 | class Player(db.Model): 9 | __tablename__ = 'players' 10 | firstname = db.Column(db.String(100), nullable=False, primary_key=True) 11 | lastname = db.Column(db.String(100), nullable=False) 12 | 13 | def __repr__(self): 14 | return '' % self.firstname + ' ' + self.lastname 15 | 16 | def to_dict(obj): 17 | if isinstance(obj.__class__, DeclarativeMeta): 18 | #
