Docker example

services:
  ashim:
    image: ashimhq/ashim:latest
    ports:
      - "1349:1349"
    volumes:
      - ashim-data:/data
      - ashim-workspace:/tmp/workspace
    environment:
      - AUTH_ENABLED=true
      - DEFAULT_USERNAME=admin
      - DEFAULT_PASSWORD=changeme
      - MAX_UPLOAD_SIZE_MB=200
      - CONCURRENT_JOBS=4
      - FILE_MAX_AGE_HOURS=12
    restart: unless-stopped

Volumes

The Docker container uses two volumes:

• /data -- Persistent storage for the SQLite database and user files. Mount this to keep users, API keys, saved pipelines, and uploaded images across container restarts.
• /tmp/workspace -- Temporary storage for images being processed. This can be ephemeral, but mounting it avoids filling up the container's writable layer.
