# Use `aria2` as downloader

Two environment variables are needed to use `aria2` as the downloader.

```bash
export COMFYUI_MANAGER_ARIA2_SERVER=http://127.0.0.1:6800
export COMFYUI_MANAGER_ARIA2_SECRET=__YOU_MUST_CHANGE_IT__
```

An example `docker-compose.yml`

```yaml
services:

  aria2:
    container_name: aria2
    image: p3terx/aria2-pro
    environment:
      - PUID=1000
      - PGID=1000

      - RPC_PORT=5080
      - DISK_CACHE=64M
      - IPV6_MODE=false
