| # KanBot backend — self-contained Docker Space. | |
| # Installs Postgres server inside the container, stores data in /data (persistent | |
| # volume), and runs the web board on port 7860. | |
| # | |
| # DB_HOST env var: if set and reachable, the web server connects to that | |
| # external Postgres instead of the local one. Falls back to local automatically. | |
| # | |
| # The HF Docker Space runtime executes the container as UID 1000, so the | |
| # Debian "postgres" user is remapped to UID 1000 here and the entrypoint runs | |
| # initdb / pg_ctl / psql directly (no `su`, which requires root). | |
