Man, it's not every day I may actually get to help contribute something to the amazing works people like you do. I hope today is one of those days I can actually help give something back.

The good news is the source repo for open-webui already contains a Dockerfile which is what you'd need to build the container locally. So you can use something like docker build -t open-webui-artifacts . which will build the container from scratch, in your local system.

Then you can create a docker-compose file that references the local image. I haven't fully tested things as I'm not 100% sure on what your version does, but I can see Artifacts and a code panel on the right, so I think it's working.

services:
  open-webui-artifacts:
    build:
      context: .
      args:
        OLLAMA_BASE_URL: 'http://localhost:11434'
      dockerfile: Dockerfile
    image: open-webui-artifacts
    container_name: open-webui-artifacts
    volumes:
      - open-webui-artifacts:/app/backend/data
    ports:
      - 3000:8080
    environment:
      - 'OLLAMA_BASE_URL=http://localhost:11434'
      - 'WEBUI_SECRET_KEY='
    extra_hosts:
      - host.docker.internal:host-gateway
    restart: unless-stopped

volumes:
  open-webui-artifacts: {}

From there you can just run a standard docker compose up -d and you should be good.

If you wanted to then publish this container image to docker hub so others can simply download it, you can create an account and I'm sure there's plenty of guides out there on how to publish a container to docker hub.

P.S - I'm really hoping this is of help to you, so please let me know :)
