Cloudflare tunnel

[mrfluffy-dev]

I setup heimdall using Yacht and it works great but I want to setup a tunnel using cloudflare. I am new to docker and everything. but I wanted to know if this is possible I know for example nextcloud AIO has a var called APACHE_PORT that allows you to set the port that the reverse proxy should listen to but I have no idea how to do this here.

Thanks in advance
