Combine multiple webinterfaces to 1 by caddy

[LittleFreak]

I’ve red a lot of the Caddy documentation in one sitting and now I don’t know anything again ^^To me more precise- I’m just more confused then before.

1. Caddy version (caddy version):

2.4.5

2. How I run Caddy:

http://192.168.178.20:80 {
reverse_proxy localhost:1080
}

a. System environment:

Raspi 4 with Debian 11, latest updates including dot.net (Kestrel) + lighttpd
running without any docker
I run a Raspi 4 with a few web services.
1. ArchiSteamFarm (Kestrel integrated, listening at port 1242)
2. Pihole (Lighttpd integrated, listening at port 1080)
3. Octoprint (without inbuild server software)

3. The problem I’m having:

I thought I could just create a start page, and let caddy redirect to the subpages with https encription.

But I never succeeded in running even 2 services accessible by caddy at the same time.

• I want 1 Start page (Including footer for quick switch)
• All 3 services should be accessible in 192.168.. only as security measure (local network only)
• All 3 services should have a separate subdomain each (f. e. “caddy.asf” or “192.168.178.19/pihole/admin”)
• Each service should have a legit https certificate to avoid annoying warnings

Is there any way to achieve that with caddy? How? I hope you can lead the way for me, because I’m lost right now

I only succeeded in using a caddy reverse proxy for 1 service yet, to avoid port conflicts between caddy with lighttpd- which doesn’t make sense yet for 1 service only, especially since I’m struggling with the certification aswell.

I also don’t know PHP- I can only write some simple HTML =/

5. What I already tried:

checking the documentation left me confused and lost on my way to solution
setting up multiple reverse proxy from port 80 of the same IP to different services failed ofc

I think this guide might be a good starting point for you:

Using Caddy as a reverse proxy in a home network

If you want to run a service inside a Local Area Network (LAN) such as your home or office – and especially if you want to be able to access it from outside that network – Caddy can help you accomplish this quite easily. This guide will show you how. It assumes you’ve never done this before, but that you have some technical proficiency and are somewhat knowledgable about your own network. Do this at your own risk. There are several ways to make private services accessible from other n…

Additional points:

• Subdomains are much better than proxying to subpaths, because many apps don’t behave well when you try to serve them in a subpath. Read more about that here: The "subfolder problem", OR, "why can't I reverse proxy my app into a subfolder?"

• You probably don’t need the IP address access. Since you’re using Pihole, you have a DNS server, and you can set up local names for each service, or you can make your real domains resolve to a LAN IP address while inside of your network (while devices outside your network would use the WAN IP by resolving using public DNS servers)

• Read through the Caddyfile structure docs Caddyfile Concepts — Caddy Documentation Essentially, you want to make a site block for each site you want to proxy to.
