Add instructions for subdomains

[alexjmccoy]

I think it would be fairly easy to add Caddy instructions for reverse proxying subdomains, i.e. nextcloud.domain.com for the various Docker containers. I'm researching this now so I might be able to contribute but I figured I'd get the issue going.

Thanks for the great project!

Yes, good idea, what do you have in mind? Caddy does have on the fly "on_demand" https mode..

*.example.com {
	tls [email protected] {
		on_demand
		}
	}

I'm thinking something like.. On your EDGE NODE

Edit Caddyfile

$ vim ~/Caddyfile

nextcloud.example.com {
	tls [email protected]

	reverse_proxy 10.1.1.2:80
	}

On your LOCAL NODE

Edit Caddyfile

nextcloud.example.com:80 {

	reverse_proxy nextcloud:80
	}

Eventually it would be good to make a full nextcloud container instruction section.

Thanks for the kind words!
