ComfyUI Setup for GCP (Google Cloud Platform)

This directory contains an updated and optimized ComfyUI setup workflow designed specifically for GCP Virtual Machines.

Key Improvements over RunPod (comfy_setup)

1. Non-Root & Home Workspace Integration:

   • Replaced fixed /workspace and /root paths with ${HOME}/workspace (~/workspace/comfyui/ComfyUI).
   • Runs cleanly as a standard GCP SSH user without requiring root privileges.
   • Logs saved to safe non-root locations (/tmp/*.log).

2. Updated PyTorch 2.11.0 (CUDA 12.8):

   • Uses PyTorch 2.11.0 with CUDA 12.8 wheels index (https://download.pytorch.org/whl/cu128).
   • Uses uv (fast Rust-based package installer) with automatic pip fallback.

3. GCP Reboot Recovery:

   • Automatically generates a local ~/workspace/restart_after_reboot.sh recovery script.
   • Restores ComfyUI server, Cloudflared tunnel, and Gradio helper UI screen sessions after VM restarts.

4. Dynamic Model & Output Directories:

   • helpers.py automatically detects and defaults model paths to ~/workspace/comfyui/ComfyUI/models/.

Quick Start

Run the setup script on your GCP VM:

cd comfy_setup_gcp
bash setup.sh

Screen Sessions

Monitor or attach to running background sessions:

# Attach to ComfyUI server logs
screen -r comfyui

# Attach to Cloudflared tunnel logs
screen -r tunnel8188

# Attach to Helper UI (CivitAI & HuggingFace downloader/uploader)
screen -r helpers

After VM Reboot

To restart all background services after rebooting your GCP instance:

bash ~/workspace/restart_after_reboot.sh
