Quick Start

Docker Installation

The fastest way to install Stacks is by using the Docker image available on Docker Hub. You can deploy it with either Docker Compose or the Docker CLI.

---

Docker Compose

Prerequisites

• Docker and Docker Compose installed
• (Recommended) FlareSolverr for solving Cloudflare/DDoS-guard
• (Optional) Anna's Archive membership for fast downloads

1. Create a file named docker-compose.yaml and add the following:

    networks:
      default:
        name: stacks
   
    services:
      stacks:
        image: zelest/stacks:latest
        container_name: stacks
        stop_signal: SIGTERM
        stop_grace_period: 30s
        ports:
          # Change the left port if 7788 is already in use
          - "7788:7788"
        volumes:
          # REQUIRED - change these paths to match your system
          - /path/to/config:/opt/stacks/config # Configuration files
          - /path/to/download:/opt/stacks/download # Downloaded files
          - /path/to/logs:/opt/stacks/logs # Log files
   
          # OPTIONAL: Separate incomplete folder (requires setting in Stacks UI)
          # Uncomment and set incomplete_folder_path to "/incomplete" in the UI
          # - "/path/to/incomplete:/opt/stacks/incomplete"
   
        restart: unless-stopped
        environment:
          # These only apply on first run, afterward edit config.yaml directly
          # or update the configuration from the UI.
          - USERNAME=admin # Default admin username (change if desired)
          - PASSWORD=stacks # Default admin password - CHANGE THIS!
   
          # Uncomment to reset the admin password to the above values on startup
          # - RESET_ADMIN=true
   
          # If you're using the included flaresolverr, this will automatically
          # connect it. If you already got it running, you can change this
          # address to match your local setup, or delete this variable and set
          # it up inside Stacks later.
          - SOLVERR_URL=flaresolverr:8191
   
          # Set your timezone:
          # https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
          - TZ=UTC
   
      # Optional, but recommended - bypasses Cloudflare and DDoS-Guard
      # protection on mirror sites. Required if you encounter 403 errors when
      # downloading. Not needed for fast downloads.
      flaresolverr:
          image: ghcr.io/flaresolverr/flaresolverr:latest
          container_name: flaresolverr
          ports:
            - "8191:8191"
          environment:
            - LOG_LEVEL=info
          restart: unless-stopped

2. Update the volume paths to wherever you want Stacks to keep its files.

3. Change PASSWORD to something secure (seriously, do this).

4. In the same directory, run:

   docker compose up

Docker CLI Installation

If you prefer running Stacks without Docker Compose, you can use the Docker CLI directly.

Prerequisites

• Docker installed
• (Recommended) FlareSolverr for solving Cloudflare/DDoS-guard
• (Optional) Anna's Archive membership for fast downloads

1. Create the required folders on your host:

   mkdir -p /path/to/config /path/to/download /path/to/logs

2. Set up the network:

   docker network create stacks

3. Set up FlareSolverr

   docker run -d \
     --name flaresolverr \
     --network stacks \
     -p 8191:8191 \
     -e LOG_LEVEL=info \
     --restart unless-stopped \
     ghcr.io/flaresolverr/flaresolverr:latest

4. Set up Stacks

   docker run -d \
     --name stacks \
     --network stacks \
     --stop-signal SIGTERM \
     -p 7788:7788 \
     -v /path/to/config:/opt/stacks/config \
     -v /path/to/download:/opt/stacks/download \
     -v /path/to/logs:/opt/stacks/logs \
     -e USERNAME=admin \
     -e PASSWORD=stacks \
     -e SOLVERR_URL=flaresolverr:8191 \
     -e TZ=UTC \
     --restart unless-stopped \
     zelest/stacks:latest

Important notes

• USERNAME and PASSWORD only apply on first run; afterward Stacks is configured via config.yaml.

• Change the left side of -p 7788:7788 if port 7788 is already taken.

• Always change the default password before exposing Stacks publicly.

• To reset the admin password later, add:

  -e RESET_ADMIN=true

First-Time Setup

1. Navigate to the web interface at http://localhost:7788
2. Log in with default credentials (or custom if set via environment variables)
3. Go to Settings tab
4. Change your password in the Login Credentials section
5. Copy your API key for usage with the Tampermonkey script in step 9
6. (Optional) Configure your Anna's Archive fast download key and enable fast downloads.
7. Adjust download delays and retry settings as needed
8. Click Save Settings
9. Install the Tampermonkey Script (see the Tampermonkey documentation for more information)

Security

Stacks implements multiple layers of security:

• Password Authentication: Bcrypt-hashed passwords with salt
• Session Management: Secure HTTPOnly cookies with SameSite protection
• Rate Limiting: 5 failed login attempts triggers 10-minute lockout
• API Key Authentication: Secure 32-character keys for external tools
• Auto-generated Secrets: API keys and session secrets generated on first run

Security Best Practices:

1. Change the default password immediately after first login
2. Use strong, unique passwords
3. Keep your API key secure
4. Don't expose Stacks directly to the internet without additional security (use a VPN or reverse proxy with HTTPS)
