docker-compose.postgres.yml

# Sublarr — PostgreSQL stack
#
# Usage:
#   docker compose -f docker-compose.postgres.yml up -d
#
# On first run Postgres initialises an empty database. Sublarr runs Alembic
# migrations automatically on startup so no manual schema setup is needed.
#
# To migrate an existing SQLite database see docs/POSTGRESQL.md.
