Minimal useful project template and Docker development environment with
- Postgres DB
- Flask app (via gunicorn) with SQLAlchemy
- Nginx web server
Assuming you have Docker installed.
Start development environment:
cd environments/dev
docker-compose up -d
(-d means run in background, if you omit it start a new terminal for the following.)
On the first start the database is empty. Initialize the SQLAlchemy models from the app server by
docker-compose run flask-gunicorn project/scripts/init_db.sh
Browse to localhost. You should see a well-known poem delivered from the database backend.
Start hacking in /project.
When done, take down containers with
docker-compose down
For more details see environments/dev/README.md.
The database data is stored in a docker volume db-data, see
docker volume ls
Should you want to remove that and start over, remove the volume by
docker volume prune
while the containers are down. Next time you start you will have to initialize the database again.
If you use this template for more than one project your container names may clash (dev_db, dev_nginx and so forth.)
Set the environment variable COMPOSE_PROJECT_NAME to a unique project name, and docker-compose will name your containers unique_name_* instead.
Alternatively use flag -p for docker-compose,
docker-compose -p unique_name [command]
