Docker Deployment

Docker provides a consistent and isolated environment for running ComfyUI in production. This guide covers Docker deployment strategies and best practices.

Quick Start

While ComfyUI doesn’t provide official Docker images in the repository, you can easily create your own Dockerfile or use community images.

Basic Dockerfile

Here’s a production-ready Dockerfile for ComfyUI:

Dockerfile

FROM nvidia/cuda:13.0-runtime-ubuntu22.04

# Set environment variables
ENV DEBIAN_FRONTEND=noninteractive \
    PYTHONUNBUFFERED=1 \
    HF_HUB_DISABLE_TELEMETRY=1 \
    DO_NOT_TRACK=1

# Install system dependencies
RUN apt-get update && apt-get install -y \
    python3.12 \
    python3-pip \
    git \
    wget \
    libgl1 \
    libglib2.0-0 \
    && rm -rf /var/lib/apt/lists/*

# Set working directory
WORKDIR /app

# Clone ComfyUI
RUN git clone https://github.com/comfyanonymous/ComfyUI.git . && \
    git checkout v0.7.0  # Replace with desired version

# Install PyTorch with CUDA support
RUN pip install --no-cache-dir torch torchvision torchaudio \
    --index-url https://download.pytorch.org/whl/cu130

# Install ComfyUI dependencies
RUN pip install --no-cache-dir -r requirements.txt

# Install manager dependencies (optional)
RUN pip install --no-cache-dir -r manager_requirements.txt

# Create directories for models and outputs
RUN mkdir -p models/checkpoints models/vae models/loras \
    models/embeddings models/upscale_models \
    input output temp

# Expose port
EXPOSE 8188

# Run ComfyUI
CMD ["python3", "main.py", "--listen", "0.0.0.0", "--port", "8188"]

Build and Run

# Build the image
docker build -t comfyui:latest .

# Run the container
docker run -d \
  --name comfyui \
  --gpus all \
  -p 8188:8188 \
  -v $(pwd)/models:/app/models \
  -v $(pwd)/output:/app/output \
  -v $(pwd)/input:/app/input \
  comfyui:latest

The --gpus all flag requires the NVIDIA Container Toolkit to be installed.

Docker Compose Setup

For easier management, use Docker Compose:

docker-compose.yml

version: '3.8'

services:
  comfyui:
    image: comfyui:latest
    container_name: comfyui
    restart: unless-stopped
    
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 1
              capabilities: [gpu]
    
    ports:
      - "8188:8188"
    
    volumes:
      - ./models:/app/models
      - ./output:/app/output
      - ./input:/app/input
      - ./custom_nodes:/app/custom_nodes
      - ./extra_model_paths.yaml:/app/extra_model_paths.yaml
    
    environment:
      - NVIDIA_VISIBLE_DEVICES=all
      - NVIDIA_DRIVER_CAPABILITIES=compute,utility
    
    command: >
      python3 main.py
      --listen 0.0.0.0
      --port 8188
      --highvram
      --preview-method taesd
      --enable-manager

Start the Service

# Start ComfyUI
docker compose up -d

# View logs
docker compose logs -f

# Stop ComfyUI
docker compose down

Multi-Stage Build (Optimized)

For smaller image sizes, use a multi-stage build:

Dockerfile.multistage

# Build stage
FROM nvidia/cuda:13.0-devel-ubuntu22.04 AS builder

ENV DEBIAN_FRONTEND=noninteractive

RUN apt-get update && apt-get install -y \
    python3.12 python3-pip git

WORKDIR /build

RUN git clone https://github.com/comfyanonymous/ComfyUI.git . && \
    git checkout v0.7.0

RUN pip install --no-cache-dir --target=/install \
    torch torchvision torchaudio \
    --index-url https://download.pytorch.org/whl/cu130

RUN pip install --no-cache-dir --target=/install -r requirements.txt

# Runtime stage
FROM nvidia/cuda:13.0-runtime-ubuntu22.04

ENV DEBIAN_FRONTEND=noninteractive \
    PYTHONUNBUFFERED=1 \
    PYTHONPATH=/install \
    HF_HUB_DISABLE_TELEMETRY=1 \
    DO_NOT_TRACK=1

RUN apt-get update && apt-get install -y \
    python3.12 \
    libgl1 \
    libglib2.0-0 \
    && rm -rf /var/lib/apt/lists/*

WORKDIR /app

COPY --from=builder /build /app
COPY --from=builder /install /install

RUN mkdir -p models/checkpoints models/vae input output temp

EXPOSE 8188

CMD ["python3", "main.py", "--listen", "0.0.0.0"]

      - comfyui-output:/app/output
      - comfyui-input:/app/input
      - comfyui-custom-nodes:/app/custom_nodes
    ports:
      - "8188:8188"
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 1
              capabilities: [gpu]

volumes:
  comfyui-models:
  comfyui-output:
  comfyui-input:
  comfyui-custom-nodes:

Shared Model Storage

Health Checks

Add health checks to ensure ComfyUI is running:

docker-compose.health.yml

services:
  comfyui:
    image: comfyui:latest
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:8188"]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 40s

Reverse Proxy Setup

Nginx

nginx.conf

server {
    listen 80;
    server_name comfyui.example.com;
    
    # Redirect to HTTPS
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    server_name comfyui.example.com;
    
    ssl_certificate /etc/nginx/ssl/cert.pem;
    ssl_certificate_key /etc/nginx/ssl/key.pem;
    
    client_max_body_size 500M;
    
    location / {
        proxy_pass http://localhost:8188;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        
        # WebSocket support
        proxy_read_timeout 86400;
    }
}

Traefik

docker-compose.traefik.yml

services:
  traefik:
    image: traefik:v2.10
    command:
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
  
  comfyui:
    image: comfyui:latest
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.comfyui.rule=Host(`comfyui.example.com`)"
      - "traefik.http.routers.comfyui.entrypoints=websecure"
      - "traefik.http.routers.comfyui.tls=true"
      - "traefik.http.services.comfyui.loadbalancer.server.port=8188"

Production Best Practices

Resource Limits

Set resource limits to prevent container from consuming all system resources:

services:
  comfyui:
    deploy:
      resources:
        limits:
          cpus: '4'
          memory: 16G
        reservations:
          memory: 8G

Restart Policies

Configure automatic restart on failure:

services:
  comfyui:
    restart: unless-stopped

Logging

Configure logging drivers to prevent disk space issues:

services:
  comfyui:
    logging:
      driver: "json-file"
      options:
        max-size: "10m"
        max-file: "3"

Security

Run as non-root user:

RUN useradd -m -u 1000 comfyui
USER comfyui

services:
  comfyui:
    user: "1000:1000"

Scaling with Docker Swarm

docker-stack.yml

version: '3.8'

services:
  comfyui:
    image: comfyui:latest
    deploy:
      replicas: 3
      update_config:
        parallelism: 1
        delay: 10s
      restart_policy:
        condition: on-failure
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 1
              capabilities: [gpu]
    ports:
      - "8188:8188"
    volumes:
      - comfyui-models:/app/models:ro
      - comfyui-output:/app/output

volumes:
  comfyui-models:
    driver: local
    driver_opts:
      type: nfs
      o: addr=nfs.example.com,rw
      device: ":/shared/models"
  comfyui-output:
    driver: local

# Deploy the stack
docker stack deploy -c docker-stack.yml comfyui

# Scale the service
docker service scale comfyui_comfyui=5

        resources:
          limits:
            nvidia.com/gpu: 1
            memory: 16Gi
          requests:
            memory: 8Gi
        volumeMounts:
        - name: models
          mountPath: /app/models
          readOnly: true
        - name: output
          mountPath: /app/output
      volumes:
      - name: models
        persistentVolumeClaim:
          claimName: comfyui-models-pvc
      - name: output
        persistentVolumeClaim:
          claimName: comfyui-output-pvc
---
apiVersion: v1
kind: Service
metadata:
  name: comfyui
spec:
  selector:
    app: comfyui
  ports:
  - protocol: TCP
    port: 8188
    targetPort: 8188
  type: LoadBalancer

Troubleshooting

GPU Not Detected

# Verify NVIDIA runtime
docker run --rm --gpus all nvidia/cuda:13.0-base nvidia-smi

# Check container toolkit
nvidia-ctk --version

Permission Issues

# Fix volume permissions
sudo chown -R 1000:1000 models output input

# Or run as current user
docker run --user $(id -u):$(id -g) ...

Out of Memory

# Increase shared memory
services:
  comfyui:
    shm_size: '2gb'

Slow Performance

# Use host network (less isolation)
docker run --network host ...

# Or enable highvram mode
command: ["python3", "main.py", "--highvram"]
