ComfyUI Docker Setup with GGUF Support and ComfyUI Manager

This guide provides detailed steps to build and run ComfyUI with GGUF support and ComfyUI Manager using Docker. The GGUF format is optimized for quantized models, and ComfyUI Manager is included for easy node management.

Prerequisites

Before starting, ensure you have the following installed on your system:

• Docker
• NVIDIA GPU with CUDA support (if using GPU acceleration)
• Create Directory structure for git repo Models and Checkpoints

mkdir -p ~/dev-ai/vison/models/checkpoints

1. Clone the ComfyUI Repository

First, navigate to ~/dev-ai/vison directory and clone the ComfyUI repository to your local machine:

cd ~/dev-ai/vison

git clone https://github.com/comfyanonymous/ComfyUI.git
cd ComfyUI

2. Create the Dockerfile

Copy the provided Dockerfile in the root of your ComfyUI directory. This file contains the necessary configurations for building the Docker container with GGUF support.

3. Build the Docker Image

docker build -t comfyui-gguf:latest .

This will create a Docker image named comfyui-gguf:latest with both ComfyUI Manager and GGUF support built in.

4. Run the Docker Container

Once the image is built, you can run the Docker container with volume mapping for your models.

docker run --name comfyui -p 8188:8188 --gpus all \
  -v /home/mukul/dev-ai/vison/models:/app/models \
  -d comfyui-gguf:latest

This command maps your local models directory to /app/models inside the container and exposes ComfyUI on port 8188.

5. Download and Place Checkpoint Models

Download and place your civitai checkpoint models in the checkpoints directory inside the container: https://civitai.com/models/139562/realvisxl-v50

To use GGUF models or other safetensor models, follow the steps below to download them directly into the checkpoints directory.

1. Navigate to the Checkpoints Directory:

   cd /home/mukul/dev-ai/vison/models/checkpoints
   

2. Download flux1-schnell-fp8.safetensors:

   wget https://huggingface.co/Comfy-Org/flux1-schnell/resolve/main/flux1-schnell-fp8.safetensors?download=true -O flux1-schnell-fp8.safetensors
   

3. Download flux1-dev-fp8.safetensors:

   wget https://huggingface.co/Comfy-Org/flux1-dev/resolve/main/flux1-dev-fp8.safetensors?download=true -O flux1-dev-fp8.safetensors
   

These commands will place the corresponding .safetensors files into the checkpoints directory.

6. Access ComfyUI

After starting the container, access the ComfyUI interface in your web browser:

http://<your-server-ip>:8188

Replace <your-server-ip> with your server's IP address or use localhost if you're running it locally.

7. Using GGUF Models

In the ComfyUI interface:

• Use the UnetLoaderGGUF node (found in the bootleg category) to load GGUF models.
• Ensure your GGUF files are correctly named and placed in the /app/models/checkpoints directory for detection by the loader node.

8. Managing Nodes with ComfyUI Manager

With ComfyUI Manager built into the image:

• Install missing nodes as needed when uploading workflows.
• Enable/Disable conflicting nodes from the ComfyUI Manager interface.

9. Stopping and Restarting the Docker Container

To stop the running container:

docker stop comfyui

To restart the container:

docker start comfyui

10. Logs and Troubleshooting

To view the container logs:

docker logs comfyui

This will provide details if anything goes wrong or if you encounter issues with GGUF models or node management.
