Step 1: Install Docker

1. Install Docker Desktop for Windows / Mac, or Docker Engine on Linux.
2. Make sure Docker is running (you can open Docker Desktop and confirm “Running”).

Step 2: Create a folder with a compose file

Create a new folder (example: quinfall-worker) and add a file named docker-compose.yml with this:

services:
  ocr_consumer:
    image: akjroller1995/quinfall-ocr-consumer:latest
    container_name: quinfall_ocr_consumer
    restart: unless-stopped
    environment:
      RABBITMQ_HOST: rabbitmq.therollermethod.com
      RABBITMQ_PORT: 5672
      RABBITMQ_USER: ocr_client
      RABBITMQ_PASS: guest1234
      RABBITMQ_INPUT_QUEUE: ocr_tasks
      RABBITMQ_OUTPUT_QUEUE: ocr_results

  watchtower:
    image: containrrr/watchtower
    container_name: quinfall_watchtower
    restart: unless-stopped
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    command: --cleanup --interval 300 quinfall_ocr_consumer

Notes: Watchtower checks every 5 minutes (300s) and automatically updates the worker if a new image is published.

Step 3: Run it

In that folder, run:

docker compose up -d

To check logs:

docker logs -f quinfall_ocr_consumer

To stop:

docker compose down

Safety / permissions

• This worker only needs access to the task queues (no admin access).
• If you ever rotate credentials, update them in the compose file.
• Watchtower needs Docker socket access to update containers.
