qBittorrent - Secure Self-Hosted BitTorrent Client

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

## Overview

qBittorrent is a popular free and open-source BitTorrent client with a large, active community. This AMI runs qbittorrent-nox, the headless daemon, and exposes its full functionality through a browser-based web interface - giving you a private, self-hosted download manager you run and control in your own AWS account. It is delivered fully installed and secured so a working client is operational within minutes of launch.

## Why This Image vs a Manual Install

This image eliminates the manual package setup, systemd unit authoring (the qbittorrent-nox package ships none), reverse-proxy configuration, and credential hardening that a manual install requires. qBittorrent's Web UI normally ships with a well-known default admin/adminadmin login; this image never keeps it. What typically requires several steps across package management, service configuration, and security hardening is completed for you at image build time. Launch the instance, read your unique credential, and start adding torrents.

## Application Stack

qbittorrent-nox is installed from the distribution repository and runs as an unprivileged system user under a hardened systemd unit. It is bound to the loopback interface only and fronted by an nginx reverse proxy on port 80. systemd starts the daemon and the web server on boot and restarts them on failure. The qBittorrent profile and the download library live on a dedicated data volume, independently resizable and separate from the OS disk.

## Security Hardening

This image follows a defence-in-depth approach:

• Network isolation: the Web UI binds exclusively to the loopback interface; only the nginx reverse proxy is exposed
• Authentication enforced: every request is authenticated, including from localhost - nothing is served anonymously
• No default or shared credentials: a cryptographically random administrator password is generated on each instance's first boot and written only to a root-only file
• Least privilege: the daemon runs as an unprivileged system user with NoNewPrivileges, PrivateTmp, and ProtectHome set
• Dedicated data volume: profile and downloads live on their own disk, surviving OS-disk changes and resizable independently
• Automatic restart: systemd monitors both qbittorrent-nox and nginx and restarts them on failure

Buyers requiring formal compliance documentation should contact cloudimg to discuss specific requirements.

## Concrete Use Cases

• Media production asset retrieval: A post-production team fetching hundreds of gigabytes of raw footage nightly via RSS rules, stored on a resizable EBS volume and synced to S3 for editing workflows
• Open-source mirror hosting: DevOps teams seeding Linux ISOs or large dataset distributions from a dedicated EC2 instance with scheduled bandwidth controls
• Research dataset distribution: Academic or data science teams downloading and sharing large public datasets via magnet links, with category-based organization and automated RSS subscriptions

## AWS Integration

Deploy on any EC2 instance type. Use the unauthenticated health endpoint with an Application Load Balancer for availability monitoring. Back up your configuration and download library using EBS snapshots or AWS Backup. Resize the dedicated download volume independently of the OS disk as your library grows. BitTorrent peer traffic uses port 6881.

## Getting Started

Read your credential from the root-only file, open the web interface in your browser, sign in, and start adding torrents by file, magnet link, or the built-in search engine. Organize downloads into categories, schedule bandwidth, and automate fetching via RSS subscriptions with rules.
