Describe the bug

Docker implementation is really great!!

Is there a way to leverage all GPUs? I have 8 Nvidia GPUs exposed. I can see all the GPUs when i run the "nvidia-smi" in the docker container.

My docker compose looks like

x-base_service: &base_service
    ports:
      - "${WEBUI_PORT:-7860}:7860"
    volumes:
      - &v1 ./data:/data
      - &v2 ./output:/output
    stop_signal: SIGKILL
    tty: true
    deploy:
      resources:
        reservations:
          devices:
              - driver: nvidia
                count: all
                capabilities: [gpu]
    runtime: nvidia
    environment:
      - NVIDIA_DRIVER_CAPABILITIES=compute,utility
      - NVIDIA_VISIBLE_DEVICES=all

name: webui-docker

services:
  download:
    build: ./services/download/
    profiles: ["download"]
    volumes:
      - *v1

  auto: &automatic
    <<: *base_service
    profiles: ["auto"]
    build: ./services/AUTOMATIC1111
    image: sd-auto:78
    environment:
      - CLI_ARGS=--allow-code --medvram --xformers --enable-insecure-extension-access --api
      - NVIDIA_DRIVER_CAPABILITIES=compute,utility
      - NVIDIA_VISIBLE_DEVICES=all

  auto-cpu:
    <<: *automatic
    profiles: ["auto-cpu"]
    deploy: {}
    environment:
      - CLI_ARGS=--no-half --precision full --allow-code --enable-insecure-extension-access --api

  comfy: &comfy
    <<: *base_service
    profiles: ["comfy"]
    build: ./services/comfy/
    image: sd-comfy:7
    environment:
      - CLI_ARGS=
      - NVIDIA_DRIVER_CAPABILITIES=compute,utility
      - NVIDIA_VISIBLE_DEVICES=all

  comfy-cpu:
    <<: *comfy
    profiles: ["comfy-cpu"]
    deploy: {}
    environment:
      - CLI_ARGS=--cpu

If all GPUs are available and visible inside container, then it is probably ComfyUI thing to make proper use of them.
Make sure using multiple GPUs is supported by Comfy in the first place.

@aimanakheel found a solution?

[aimanakheel]

i did not. Perhaps this may not be the correct forum for this ticket. May be need to open a ticket with comfyUI team.

I'm still not sure if it is a comfyUI problem. I tried with auto . nvidia-smi shows all GPUs and I rewrote docker compose to be count: all. However, only one GPU is used.
