To set up the development environment:

1. docker-compose up -d postgres
2. docker-compose up -d airflow37 # or other version
3. docker logs -f airflow_airflow37_1
4. Wait until you see "Installation ready. Start doing nothing..."
5. docker exec -it airflow_airflow37_1 bash
6. You're good to go, e.g.:

• airflow webserver
