relates to issue #1339

Adds reference to a fully documented cloud-oriented docker image for use at RunPod, Vast, Paperspace and others.

I think this will be better to merge this PR (https://github.com/comfyanonymous/ComfyUI/pull/1469) and to include a docker/docker-compose install in the main repo

Unfortunately there is no docker compose support in the intended environments (runpod, vast etc) so this image has to include extras for usability:

• Reverse proxy for authentication support
• Logging Web UI
• ... As documented

Yes, your repo is fantastic but it include much more than just ComfyUI and things that may not belong here. If I docker may be include here it must be a minimal one. Btw I love the rclone feature of your repo <3

But a note in the README is fine I suppose, howerver we are still waiting for the https://github.com/comfyanonymous/ComfyUI/pull/1469 PR to be merged

[robballantyne]

Thank you. Yes it's far more than ComfyUI, so I only suggested a Readme note for those of us without GPUs.

The PR you referenced is more important than this in ComfyUI's own scope, this is really an extra - Though it's also fine for local use, it's not the 'docker way', but these services offer one container only, so everything has to be bundled.

I support the idea of adding a Dockerfile / docker-compose.yml in the repo. Containers are the best way to run these UIs IMHO, even locally
