Deploy with Docker

The easiest way to self-host BentoPDF in a production environment.

IMPORTANT

Required Headers for Office File Conversion

LibreOffice-based tools (Word, Excel, PowerPoint conversion) require these HTTP headers for SharedArrayBuffer support:

• Cross-Origin-Opener-Policy: same-origin
• Cross-Origin-Embedder-Policy: require-corp

The official Docker images include these headers. If using a reverse proxy (Traefik, Caddy, etc.), ensure these headers are preserved or added.

Quick Start

docker run -d \
  --name bentopdf \
  -p 3000:8080 \
  --restart unless-stopped \
  ghcr.io/alam00000/bentopdf:latest

Docker Compose

Create docker-compose.yml:

services:
  bentopdf:
    image: ghcr.io/alam00000/bentopdf:latest
    container_name: bentopdf
    ports:
      - "3000:8080"
    restart: unless-stopped
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:8080"]
      interval: 30s
      timeout: 10s
      retries: 3

Run:

docker compose up -d

Build Your Own Image
