Torrent Server + Telegram Bot

This project runs a Telegram bot that can queue torrents in qBittorrent, track progress, and provide download links for completed files via an HTTP file server.

Prerequisite

• Docker + Docker Compose must be installed.

This README assumes you run everything with docker compose.

Quick start

1. Clone the repository and enter it.

2. Create your runtime env file:

   cp .env.example .env

3. Fill in .env (see Environment variables).

4. Create required bind-mount directories:

   mkdir -p \
     volumes/downloads \
     volumes/auth \
     volumes/qbittorrent_config \
     volumes/nginxproxymanager/data \
     volumes/nginxproxymanager/letsencrypt

5. Start services:

   docker compose up -d --build

6. Handle first qBittorrent login/password initialization (important):

   • On first launch, qBittorrent logs a temporary admin password.

   • Read it with:

     docker compose logs qbittorrent | rg -i "temporary password|admin password|password"

   • Open qBittorrent Web UI (http://localhost:8080) and sign in with the temporary password.

   • Change username/password in qBittorrent Web UI to match your .env values:

     • QBITTORRENT_USERNAME
     • QBITTORRENT_PASSWORD

7. Restart containers after changing qBittorrent credentials:

   • Recommended because the bot initializes its torrent service on startup and may attempt login before qBittorrent has fully persisted updated credentials.

   docker compose down
   docker compose up -d

Environment variables

Rename .env.example to .env and fill all values.

Variable	Required	What it is for
TELEGRAM_BOT_TOKEN	Yes	Telegram Bot API token from BotFather.
BOT_OWNER_USER_ID	Yes	Telegram user_id of the bot owner/admin (allowed to run admin-only commands).
QBITTORRENT_URL	Yes	qBittorrent Web UI/API URL used by the bot (for Docker Compose default: http://qbittorrent:8080).
QBITTORRENT_USERNAME	Yes	qBittorrent Web UI username used by the bot API client.
QBITTORRENT_PASSWORD	Yes	qBittorrent Web UI password used by the bot API client.
TORRENT_INPUT_TMP_DIR	Yes	Temp folder inside the bot container for uploaded .torrent files before queueing.
AUTH_DB_PATH	Yes	SQLite file path for whitelist/auth data (default compose path: /auth/auth.db).
ACTIVE_DOWNLOADS_ROOT	Yes	Path where in-progress torrent data is stored.
FINISHED_DOWNLOADS_ROOT	Yes	Path where completed downloads are stored (served by file server).
DOWNLOAD_RECORDS_DB_PATH	Yes	SQLite path used to track download records/metadata.
FINISHED_DOWNLOAD_RETENTION_DAYS	Yes	Retention period for completed downloads/records.
HFS_BASE_URL	Yes	Base URL for the file server used when generating user download links.
DOWNLOAD_LINK_SECRET	Yes	Secret used to sign generated download links. Use a long random value.
DOWNLOAD_LINK_TTL_SECONDS	Yes	Link expiration time (in seconds) for generated download links.

Generate a strong value for DOWNLOAD_LINK_SECRET (example):

python3 -c "import secrets; print(secrets.token_urlsafe(48))"

Services in docker-compose.yml

• bot: Telegram bot application.
• qbittorrent: torrent engine + Web UI.
• file-server: serves completed downloads over HTTP.
• nginxproxymanager: reverse proxy manager that can be used for HTTPS/SSL and routing.

Why nginxproxymanager is included

nginxproxymanager is included for potential SSL enforcement and URL routing, including:

• redirecting custom domain URLs to qBittorrent Web UI,
• redirecting custom domain URLs to the HFS/file-server endpoint,
• optionally enforcing HTTP → HTTPS.

Default Nginx Proxy Manager admin UI: http://localhost:81.

qBittorrent first-run notes

• The LinuxServer qBittorrent container emits a temporary admin password on first startup.
• You must use that password once to log in and set your final credentials.
• After setting final credentials, restart the full compose stack so the bot consistently authenticates with the updated values.

Available bot commands

General

• /start — entry command.
• /authenticate <token> — authenticate and join whitelist.
• /cancel — cancel the currently pending multi-step command input.

Whitelisted users

• /queuedownload — queue a torrent file or magnet link.
• /status — view current torrent progress.
• /canceldownload — cancel and remove an active download.
• /getdownloadlink — get a link for a finished download.
• /deletefiles — delete finished downloads.
• /myfolder — get your personal folder link.

Admin only (owner)

• /generateaccesstoken — generate one-time authentication token.
• /removeuser <user_id> — remove a user from whitelist.
• /whitelist — list whitelisted users.
• /availablespace — show available disk space.

Common operations

Start/restart:

docker compose up -d --build

Stop:

docker compose down

View logs:

docker compose logs -f bot
docker compose logs -f qbittorrent

Notes

• Keep your .env out of version control.
• Use strong secrets/passwords in production.
• If you put qBittorrent and file server behind a public domain, configure TLS via nginxproxymanager.
