Microservices with Docker, Flask, and React
This application is an example of a micro-services architecture using Docker, Flask and React from the online course, Microservices with Docker, Flask, and React
Manage the Application
- Deploy the application:
docker-compose -f docker-compose-dev.yml up -d --build - Create the database:
docker-compose -f docker-compose-dev.yml run users python manage.py recreate-db - Seed the database:
docker-compose -f docker-compose-dev.yml run users python manage.py seed-db - Run the Python tests:
docker-compose -f docker-compose-dev.yml run users python manage.py test - Run the Python tests with coverage:
docker-compose -f docker-compose-dev.yml run users python manage.py cov - Run Flake8:
docker-compose -f docker-compose-dev.yml run users flake8 project - Run the client-side (npm) tests:
docker-compose -f docker-compose-dev.yml run client npm test - Access the container logs:
docker-compose -f docker-compose-dev.yml logs -f - Access the Postgres container:
docker-compose -f docker-compose-dev.yml exec users-db psql -U postgres
Run a Multi-Stage Docker Build for the Client
docker build -f Dockerfile-prod -t "test" ./ \
--build-arg NODE_ENV=development \
--build-arg REACT_APP_USERS_SERVICE_URL=http://127.0.0.1
Running Database Migrations
- Create a migration repository:
docker-compose -f docker-compose-dev.yml run users python manage.py db init - Generate an initial migration:
docker-compose -f docker-compose-dev.yml run users python manage.py db migrate - Apply the migrations to the database:
docker-compose -f docker-compose-dev.yml run users python manage.py db upgrade
Access the Application
- Homepage: http://localhost
- Users: http://localhost/users
Working With the Postgres Database
Once you access the Postgres database (see above):
- Choose the
users_devdatabase:# \c users_dev - Describe the
userstable:# \d+ users - Select all of the users:
# select * from users;
