[Guide] How to securely run ComfyUI on Windows (Docker>WSL2) [RTX 3090, logic can be applied to other hardware]

ComfyUI is a node-based interface for Stable Diffusion that can be run on Windows using Docker and WSL2 (Windows Subsystem for Linux 2) for improved security and performance. This guide provides instructions for setting up ComfyUI in a containerized environment on Windows systems, with specific examples using RTX 3090 GPUs, though the methodology can be adapted for other hardware configurations. The approach leverages Docker virtualization to isolate the application while maintaining access to GPU acceleration for AI image generation tasks.
