# Portainer Stack Definition for School Compare
#
# Portainer environment variables (set in Portainer UI -> Stack -> Environment):
#   DB_USERNAME            — PostgreSQL username
#   DB_PASSWORD            — PostgreSQL password
#   DB_DATABASE_NAME       — PostgreSQL database name
#   ADMIN_API_KEY          — Backend admin API key
#   TYPESENSE_API_KEY      — Typesense admin API key
#   TYPESENSE_SEARCH_KEY   — Typesense search-only key (exposed to frontend)
#   UNLEASH_URL            — http://<unleash-ip>:4242/api (empty = all flags off)
#   UNLEASH_API_TOKEN      — Unleash *client* token, environment: production
#   AIRFLOW_ADMIN_USER     — Airflow admin username (default: admin)
#   AIRFLOW_ADMIN_PASSWORD — Airflow admin password. REQUIRED: the api-server
#                            refuses to start without it, rather than falling
#                            back to a generated one that changes on restart.
