This was the repo: https://github.com/amalshaji/portr

And this was my gh issue: https://github.com/amalshaji/portr/issues/308

And below was my prompt:

""" give me single docker-compose file that i can run on my server to run current project... you can read README.md , and then, this relevant page: https://docs-custom-reverse-proxy.portr-docs.pages.dev/docs/... ... this was the result of me raising github issue: https://github.com/amalshaji/portr/issues/308 ... you can use gh cli to fetch the details and comments...

i already have a caddy server running on my vps... and i will create wildcard certificates myself using certbot.. the domain name will be helloportr.xyz ... also, ports up to 9019 are already taken...

ask me if anymore info is needed... """

You can try yourself and let me know of what you got.
