docker-compose.yaml

# Development environment with MySQL, PostgreSQL, and S3 (SeaweedFS) services
#
# NOTE: docker-compose is OPTIONAL for running tests.
# Tests use testcontainers to automatically manage containers.
# Just run: pytest tests/
#
# Use docker-compose for development/debugging when you want
# persistent containers that survive test runs:
#   docker compose up -d db s3      # Start services manually
#   pytest tests/                    # Tests will use these containers
#
# Full Docker testing (CI):
#   docker compose --profile test up djtest --build
