## About

This repository automates the creation of Docker images for [ComfyUI](https://github.com/comfyanonymous/ComfyUI), a powerful and modular stable diffusion GUI and backend. It syncs with the upstream ComfyUI repository, builds a Docker image on new releases, and pushes it to GitHub Container Registry (GHCR).

I created this repo for myself as a simple way to stay up to date with the latest ComfyUI versions while having an easy-to-use Docker image. It's particularly suited for setups with **NVIDIA GPUs**, leveraging CUDA for accelerated performance.

### Built With
- [Docker](https://www.docker.com/)
- [GitHub Actions](https://github.com/features/actions) for automation
- [PyTorch](https://pytorch.org/) with CUDA support
- Based on Python 3.12 slim image

---

## Features
- **Automated Sync & Build**: Daily checks for upstream releases, auto-merges changes, and builds/pushes Docker images.
- **NVIDIA GPU Ready**: Pre-configured with CUDA-enabled PyTorch for seamless GPU acceleration.
- **Non-Root Runtime**: Runs as a non-root user for better security.
- **Pre-Installed Manager**: Includes ComfyUI-Manager for easy node/extensions management.

---

## Getting Started

### Prerequisites
- **Docker**: Installed on your host (e.g., Docker Desktop or Engine).
- **NVIDIA GPU**: For GPU support (ensure NVIDIA drivers and CUDA are installed on the host).
- **NVIDIA Container Toolkit**: For GPU passthrough in Docker (install via [official guide](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html)).

### Pulling the Image
The latest image is available on GHCR:

```bash
docker pull ghcr.io/clsferguson/comfyui-docker:latest
```

For a specific version (synced with upstream tags, starting at 0.3.57):
```bash
docker pull ghcr.io/clsferguson/comfyui-docker:vX.Y.Z
```

### Docker Compose
For easier management, use this `docker-compose.yml`:

```yaml
services:
  comfyui:
    image: ghcr.io/clsferguson/comfyui-docker:latest
    container_name: ComfyUI
    runtime: nvidia
    restart: unless-stopped
    ports:
      - 8188:8188
    environment:
      - TZ=America/Edmonton
      - PUID=1000
      - GUID=1000
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: all
              capabilities: [gpu]
    volumes:
      - comfyui_data:/app/ComfyUI/user/default
      - comfyui_nodes:/app/ComfyUI/custom_nodes
      - /mnt/comfyui/models:/app/ComfyUI/models
      - /mnt/comfyui/input:/app/ComfyUI/input
      - /mnt/comfyui/output:/app/ComfyUI/output
```

Run with `docker compose up -d`.

---

## Usage

### Basic Usage
Access ComfyUI at `http://localhost:8188` after starting the container using Docker Compose.

### Environment Variables
- Set via `.env` file or `-e` flags in `docker compose` or `docker run`.
