Runbook (operational guide)

This document covers running the application, checking health, logs, common errors, and database operations.

Starting and stopping

Local

• Start: From the repository root, with virtualenv activated:

  python main.py
  

  Or after pip install -e .: duty-teller
• Stop: Ctrl+C

Docker

• Dev (code mounted; no rebuild needed for code changes):

  docker compose -f docker-compose.dev.yml up --build
  

  Stop: Ctrl+C or docker compose -f docker-compose.dev.yml down.

• Prod (built image; restarts on failure):

  docker compose -f docker-compose.prod.yml up -d --build
  

  Stop: docker compose -f docker-compose.prod.yml down.

On container start, entrypoint.sh runs Alembic migrations then starts the app as user botuser. Ensure .env (or your orchestrator’s env) contains BOT_TOKEN and any required variables; see configuration.md.

Health check

• HTTP: The FastAPI app serves the API and static webapp. A simple way to verify it is up is to open the interactive API docs: GET /docs (e.g. http://localhost:8080/docs). If that page loads, the server is running.
• There is no dedicated /health endpoint; use /docs or a lightweight API call (e.g. GET /api/duties?from=...&to=... with valid auth) as needed.

Logs

• Local: Output goes to stdout/stderr; redirect or use your process manager’s logging (e.g. systemd, supervisord).
• Docker: Use docker compose logs -f (with the appropriate compose file) to follow application logs. Adjust log level via Python logging if needed (e.g. environment or code).

Common errors and what to check

"hash_mismatch" (403 from /api/duties or Miniapp)

• Cause: The server that serves the Mini App (e.g. production host) uses a different BOT_TOKEN than the bot from which users open the Mini App (e.g. test vs production bot). Telegram signs initData with the bot token; if tokens differ, validation fails.
• Check: Ensure the same BOT_TOKEN is set in .env (or equivalent) on the machine serving /api/duties as the one used by the bot instance whose menu button opens the Miniapp.

Miniapp "Open in browser" or direct link — access denied

• Cause: When users open the calendar via “Open in browser” or a direct URL, Telegram may not send tgWebAppData (initData). The API requires initData (or MINI_APP_SKIP_AUTH in dev).
• Action: Users should open the calendar via the bot’s menu button (e.g. ⋮ → "Calendar") or a Web App inline button so Telegram sends user data.

403 "Open from Telegram" / no initData

• Cause: Request to /api/duties or /api/calendar-events without valid X-Telegram-Init-Data header. The API returns 403 without initData; the only bypass is MINI_APP_SKIP_AUTH=1 (dev only, insecure).
• Check: Ensure the Mini App is opened from Telegram (menu or inline button). For local dev without Telegram, use MINI_APP_SKIP_AUTH=1 in .env.

Mini App URL — redirect and broken auth

• Cause: If the Mini App URL is configured without a trailing slash (e.g. https://your-domain.com/app) and the server redirects /app → /app/, the browser can drop the fragment Telegram sends, breaking authorization.
• Action: Configure the bot’s menu button / Web App URL with a trailing slash, e.g. https://your-domain.com/app/. See README “Mini App URL”.

User not in allowlist (403)

• Cause: Telegram user’s username is not in ALLOWED_USERNAMES or ADMIN_USERNAMES, and (if using phone) their phone (set via /set_phone) is not in ALLOWED_PHONES or ADMIN_PHONES.
• Check: configuration.md for ALLOWED_USERNAMES, ADMIN_USERNAMES, ALLOWED_PHONES, ADMIN_PHONES. Add the user or ask them to set phone and add it to the allowlist.

Database and migrations

• Default DB path (SQLite): data/duty_teller.db (relative to working directory when using default DATABASE_URL=sqlite:///data/duty_teller.db). In Docker, the entrypoint creates /app/data and runs migrations there.
• Migrations (Alembic): From the repository root:

  alembic -c pyproject.toml upgrade head
  

  Config: pyproject.toml → [tool.alembic]; script location alembic/; metadata and URL from duty_teller.config and duty_teller.db.models.Base.
• Rollback: Use with care; test in a copy of the DB first. Example to go back one revision:

  alembic -c pyproject.toml downgrade -1
  

  Always backup the database before downgrading.

For full list of env vars (including DATABASE_URL), see configuration.md. For reverse proxy and Mini App URL details, see the main README.
